GENERAL POWER TOOL SAFETY WARNINGS

WARNING

Read all safety warnings, instructions,

illustrations and specifications provided with

this power tool. Failure to follow all instructions

listed below may result in electric shock, fire and/

or serious injury.

Save all warnings and instructions for future

reference.The term “power tool” in the warnings

refers to your mains-operated (corded) power tool

or battery-operated (cordless) power tool.

WORK AREA SAFETY

 Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

 Do not operate power tools in explosive

atmospheres, such as in the presence of

flammable liquids, gases or dust. Power tools

create sparks which may ignite the dust or fumes.

 Keep children and bystanders away while

operating a power tool. Distractions can cause

you to lose control.

ELECTRICAL SAFETY

 Power tool plugs must match the outlet. Never

modify the plug in any way. Do not use any

adapter plugs with earthed (grounded) power

tools. Unmodified plugs and matching outlets

will reduce risk of electric shock.

 Avoid body contact with earthed or grounded

surfaces such as pipes, radiators, ranges

and refrigerators. There is an increased risk

of electric shock if your body is earthed or

grounded.

 Do not expose power tools to rain or wet

conditions. Water entering a power tool will

increase the risk of electric shock.

 Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool.

Keep cord away from heat, oil, sharp edges

or moving parts. Damaged or entangled cords

increase the risk of electric shock.

 When operating a power tool outdoors, use

an extension cord suitable for outdoor use.

Use of a cord suitable for outdoor use reduces

the risk of electric shock.

 If operating a power tool in a damp location

is unavoidable, use a ground fault circuit

interrupter (GFCI) protected supply. Use of a

GFCI reduces the risk of electric shock.

PERSONAL SAFETY

 Stay alert, watch what you are doing and

use common sense when operating a power

tool. Do not use a power tool while you are

tired or under the influence of drugs, alcohol

or medication. A moment of inattention while

operating power tools may result in serious

personal injury.

 Use personal protective equipment. Always

wear eye protection. Protective equipment

such as dust mask, non-skid safety shoes, hard

hat, or hearing protection used for appropriate

conditions will reduce personal injuries.

 Prevent unintentional starting. Ensure the

switch is in the off-position before connecting

to power source and/or battery pack, picking

up or carrying the tool. Carrying power tools

with your finger on the switch or energising power

tools that have the switch on invites accidents.

 Remove any adjusting key or wrench before

turning the power tool on. A wrench or a key

left attached to a rotating part of the power tool

may result in personal injury.

 Do not overreach. Keep proper footing and

balance at all times. This enables better control

of the power tool in unexpected situations.

 Dress properly. Do not wear loose clothing

or jewellery. Keep your hair, clothing and

gloves away from moving parts. Loose clothes,

jewellery or long hair can be caught in moving

parts.

3 - English

GENERAL POWER TOOL SAFETY WARNINGS

 If devices are provided for the connection

of dust extraction and collection facilities,

ensure these are connected and properly

used. Use of dust collection can reduce dust-

related hazards.

 Do not let familiarity gained from frequent use

of tools allow you to become complacent and

ignore tool safety principles. A careless action

can cause severe injury within a fraction of a

second

POWER TOOL USE AND CARE

 Do not force the power tool. Use the correct

power tool for your application. The correct

power tool will do the job better and safer at the

rate for which it was designed.

 Do not use the power tool if the switch does

not turn it on and off. Any power tool that cannot

be controlled with the switch is dangerous and

must be repaired.

 Disconnect the plug from the power source

and/or the battery pack from the power tool

before making any adjustments, changing

accessories, or storing power tools. Such

preventive safety measures reduce the risk of

starting the power tool accidentally.

 Store idle power tools out of the reach of

children and do not allow persons unfamiliar

with the power tool or these instructions

to operate the power tool. Power tools are

dangerous in the hands of untrained users.

 Maintain power tools. Check for misalignment

or binding of moving parts, breakage of parts

and any other condition that may affect the

power tool’s operation. If damaged, have

the power tool repaired before use. Many

accidents are caused by poorly maintained

power tools.

 Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges

are less likely to bind and are easier to control.

 Use the power tool, accessories and tool bits

etc. in accordance with these instructions,

taking into account the working conditions

and the work to be performed. Use of the

power tool for operations different from those

intended could result in a hazardous situation.

 Keep handles and grasping surfaces dry,

clean and free from oil and grease. Slippery

handles and grasping surfaces do not allow

for safe handling and control of the tool in

unexpected situations.

BATTERY TOOL USE AND CARE

 Recharge only with the charger specified by

the manufacturer. A charger that is suitable for

one type of battery pack may create a risk of fire

when used with another battery pack.

 Use power tools only with specifically

designated battery packs. Use of any other

battery packs may create a risk of injury and fire.

 When battery pack is not in use, keep it away

from other metal objects, like paper clips,

coins, keys, nails, screws or other small metal

objects, that can make a connection from

one terminal to another. Shorting the battery

terminals together may cause burns or a fire.

 Under abusive conditions, liquid may be

ejected from the battery; avoid contact. If

contact accidentally occurs, flush with water.

If liquid contacts eyes, additionally seek

medical help. Liquid ejected from the battery

may cause irritation or burns.

 Do not use a battery pack or tool that is

damaged or modified. Damaged or modified

batteries may exhibit unpredictable behaviour

resulting in fire, explosion or risk of injury.

 Do not expose a battery pack or tool to fire

or excessive temperature. Exposure to fire or

temperature above 265°F may cause explosion.

 Follow all charging instructions and do not

charge the battery pack or tool outside the

temperature range specified in the instructions.

Charging improperly or at temperatures outside

the specified range may damage the battery and

increase the risk of fire.

SERVICE

 Have your power tool serviced by a qualified

repair person using only identical replacement

parts. This will ensure that the safety of the

power tool is maintained.

CHAIN SAW SAFETY WARNINGS

 Keep all parts of the body away from the

saw chain when the chain saw is operating.

Before you start the chain saw, make sure

the saw chain is not contacting anything. A

moment of inattention while operating chain

saws may cause entanglement of your clothing

or body with the saw chain.

 Always hold the chain saw with your right

hand on the rear handle and your left hand on

the front handle. Holding the chain saw with a

reversed hand configuration increases the risk

of personal injury and should never be done.

 Hold the power tool by insulated gripping

surfaces only, because the saw chain may

contact hidden wiring. Saw chains contacting

a “live” wire may make exposed metal parts of

the power tool “live” and could give the operator

an electric shock.

 Wear eye protection. Further protective

equipment for hearing, head, hands, legs and

feet is recommended. Adequate protective

equipment will reduce personal injury from flying

debris or accidental contact with the saw chain.

 Do not operate a chain saw, on a ladder, from

a rooftop, or any unstable support. Operation

of a chain saw in this manner could result in

serious personal injury.

NOTE: The size of the work area depends on the

job being performed as well as the size tree or

work piece involved. For example, felling a tree

requires a larger work area than making bucking

cuts.

 Do not operate a chain saw in a tree unless

you have been specifically trained to do

so. Operation of a chain saw in a tree without

proper training could increase the risk of serious

personal injury.

 Always keep proper footing and operate

the chain saw only when standing on fixed,

secure and level surface. Slippery or unstable

surfaces such as ladders may cause a loss of

balance or control of the chain saw.

 When cutting a limb that is under tension be

alert for spring back. When the tension in the

wood fibres is released the spring loaded limb

may strike the operator and/or throw the chain

saw out of control.

 Use extreme caution when cutting brush and

saplings. The slender material may catch the

saw chain and be whipped toward you or pull

you off balance.

 Follow all instructions when clearing jammed

material, storing or servicing the chain saw.

Make sure the switch is off and the battery

pack is removed. Unexpected actuation of the

chain saw while clearing jammed material or

servicing may result in serious personal injury.

 Carry the chain saw by the front handle with

the chain saw switched off and away from

your body. When transporting or storing the

chain saw always fit the guide bar cover.

Proper handling of the chain saw will reduce the

likelihood of accidental contact with the moving

saw chain.

 Follow instructions for lubricating, chain

tensioning and changing the bar and chain.

Improperly tensioned or lubricated chain may

either break or increase the chance for kickback.

 Cut wood only. Do not use chain saw for

purposes not intended. For example: do not

use chain saw for cutting plastic, masonry

or non-wood building materials. Use of the

chain saw for operations different than intended

could result in a hazardous situation.

GENERAL POWER TOOL SAFETY WARNINGS

 Never service damaged battery packs. Service

of battery packs should only be performed by the

manufacturer or authorized service providers.

 When servicing a power tool, use only identical

replacement parts. Follow instructions in

the Maintenance section of this manual.

Use of unauthorized parts or failure to follow

maintenance instructions may create a risk of

shock or injury.

5 - English

CHAIN SAW SAFETY WARNINGS

 Do not attempt to fell a tree until you have an

understanding of the risks and how to avoid

them. Serious injury could occur to the operator

or bystanders while felling a tree.

CAUSES AND OPERATOR

PREVENTION OF KICKBACK

Kickback may occur when the nose or tip of the

guide bar touches an object, or when the wood

closes in and pinches the saw chain in the cut.

Tip contact in some cases may cause a sudden

reverse reaction, kicking the guide bar up and back

towards the operator.

Pinching the saw chain along the top of the guide

bar may push the guide bar rapidly back towards

the operator.

Either of these reactions may cause you to lose

control of the saw which could result in serious

personal injury. Do not rely exclusively upon the

safety devices built into your saw. As a chain saw

user, you should take several steps to keep your

cutting jobs free from accident or injury.

Kickback is the result of tool misuse and/or

incorrect operating procedures or conditions and

can be avoided by taking proper precautions as

given below:

 Maintain a firm grip, with thumbs and fingers

encircling the chain saw handles, with both

hands on the saw and position your body

and arm to allow you to resist kickback

forces. Kickback forces can be controlled by

the operator, if proper precautions are taken.

Do not let go of the chain saw.

 Do not overreach and do not cut above

chest height. This helps prevent unintended tip

contact and enables better control of the chain

saw in unexpected situations.

 Only use replacement bars and chains

specified by the manufacturer. Incorrect

replacement bars and chains may cause chain

breakage and/or kickback.

 Follow the manufacturer’s sharpening and

maintenance instructions for the saw chain.

Decreasing the depth gauge height can lead to

increased kickback.

 Do not start cutting until you have a clear work

area, secure footing, and a planned retreat

path from the falling tree. Cluttered areas invite

accidents.

 Keep ALL children, bystanders, visitors, and

animals out of the work area while starting or

cutting with the chain saw. Do not let visitors

contact chain saw or extension cord.

 Do not operate chain saw in explosive

atmospheres, such as in the presence of

flammable liquids, gases, or dust. Chain saws

create sparks which may ignite the dust or

fumes.

 Dress Properly – Wear snug fitting clothing.

Always wear heavy, long pants, long sleeves,

overalls, jeans or chaps made of cut resistant

material or ones that contain cut resistant

inserts. Wear non-slip safety footwear. Wear

non-slip heavy duty gloves to improve your

grip and to protect your hands. Do not wear

jewelry, short pants, sandals, or go barefoot.

Do not wear loose fitting clothing, which could

be drawn into the motor or catch the chain or

underbrush. Secure hair so it is above shoulder

level. Wear hearing and head protection.

 Heavy protective clothing may increase operator

fatigue, which could lead to heat stroke. During

weather that is hot and humid, heavy work

should be scheduled for early morning or late

afternoon hours when temperatures are cooler.

 Always wear eye protection with side shields

marked to comply with ANSI Z87.1 as well as

hearing and head protection when operating

this equipment.

 Always be aware of what you are doing when

using the chain saw. Use common sense. Do

not operate the chain saw when you are tired, ill,

upset, or under the influence of alcohol, drugs,

or medication.

 Do not expose the chain saw to rain.

 Do not use the chain saw in damp or wet

locations.

 Stay alert and pay attention to what you are

doing. Use common sense when using this unit.

6 - English

CHAIN SAW SAFETY WARNINGS

 Keep all parts of your body away from the saw

chain when the unit is running.

 Never let anyone use your chain saw who has

not received adequate instructions in its proper

use. This applies to rentals as well as privately

owned saws.

 Before you start the unit, make sure the saw

chain is not contacting any object.

 Stop the chain saw before setting it down.

 To avoid accidental starting, never carry the unit

with your finger on the switch trigger.

 Maintain the unit with care. Keep the cutting

edge sharp and clean for best performance and

to reduce the risk of injury. Follow instructions

for lubricating and changing accessories.

 Do not operate a chain saw with one hand!

Use a firm grip with thumbs and fingers

encircling the chain saw handles. Serious injury

to the operator, helpers, bystanders, or any

combination of these persons may result from

one-handed operation. A chain saw is intended

for two-handed use.

 Guard against electric shock – Avoid body

contact with grounded surfaces such as metal

pipes and wire fences. There is an increased

risk of electric shock if your body is grounded.

 Do not operate a chain saw that is damaged,

improperly adjusted, or not completely and

securely assembled. Chain should slow to a

stop when the switch trigger is released. If the

chain continues to turn after the switch trigger

has been released, have the unit serviced by an

authorized service center.

 Check for damaged parts. Check for alignment

of moving parts, binding of moving parts,

breakage of parts, mounting, and any other

conditions that may affect its operation. A guard

or other part that is damaged should be properly

repaired or replaced by an authorized service

center unless otherwise indicated elsewhere in

this manual.

 All chain saw service, other than the items listed

in the operation and maintenance sections,

should be performed by an authorized service

center.

 Always maintain a proper stance.

 Do not use chain saw if switch does not turn it on

and off. Have switch replaced by an authorized

service center.

 Do not adapt your power head to a bow guide

or use it to power any attachments or devices

not listed for the saw.

 Disconnect chain saw from power supply when

not in use, before servicing, and when making

adjustments and changing attachments, such

as saw chain and guard.

 Do not cut vines and/or small underbrush.

 Do not force the chain saw. The job can be

performed better and safer at the rate for which

it was intended.

 When clearing jammed material or servicing

the unit, make sure all power switches

are off and the battery pack is removed or

disconnected. Unexpected actuation of the

chain saw while clearing jammed material or

servicing may result in serious personal injury.

 Always use the right product for your application.

The chain saw should be used for cutting wood

only. Never use the chain saw to cut plastic,

masonry or non-wood building materials.

 Store chain saw when not charging or when not

in use. Chain saw should be stored in a dry and

high or locked area out of the reach of children.

When storing chain saw place the scabbard on

the bar and chain.

 Use this product only with batteries and

chargers listed in tool/appliance/battery pack/

charger correlation supplement 987000-432.

 Battery operated units do not have to be

plugged into an electrical outlet; therefore, they

are always in operating condition. Be aware

of possible hazards even when unit is not

operating.

 Remove the battery pack from the chain

saw when not charging and before cleaning,

7 - English

CHAIN SAW SAFETY WARNINGS

servicing, storing, removing material from the

unit, changing accessories such as the bar and

chain, or when not in use.

 Never use water or any liquids to clean or rinse

off your product and do not expose the product

to rain or wet conditions. Store indoors in a dry

area. Corrosive liquids, water, and chemicals

can enter the product’s electronic components

and/or battery compartment and damage

electronic components and/or the battery pack,

which can result in a short circuit, increased risk

of fire, and serious personal injury. Remove any

buildup of dirt and debris by wiping the product

clean with a dry cloth occasionally.

KICKBACK

See Figures 1 - 3.

WARNING

Kickback may occur when the moving chain

contacts an object at the upper portion of the

tip of the guide bar or when the wood closes in

and pinches the saw chain in the cut. Contact at

the upper portion of the tip of the guide bar can

cause the chain to dig into the object and stop

the chain for an instant. The result is a lightning

fast, reverse reaction which kicks the guide bar

up and back toward the operator. If the saw

chain is pinched along the top of the guide bar,

the guide bar can be driven rapidly back toward

the operator. Either of these reactions can cause

loss of saw control which can result in serious

injury. Do not rely exclusively upon the safety

devices built into the saw. As a chain saw user,

you should take several steps to keep your

cutting jobs free from accident or injury.

 The following precautions should be followed

to minimize kickback:

• Always grip the saw firmly with both hands.

Hold the saw firmly with both hands when

the unit is running. Place your right hand on

the rear handle and your left hand on the

front handle with your thumbs and fingers

encircling the chain saw handles. A firm grip

together with a stiff left arm will help you

maintain control of the saw if kickback occurs.

• Make sure that the area in which you are

cutting is free from obstructions. Do not let the

nose of the guide bar contact a log, branch,

fence, or any other obstruction that could be

hit while you are operating the saw.

• Always cut with the unit running at full speed.

Fully squeeze the throttle trigger and maintain

a steady cutting speed.

• Use replacement parts such as low kickback

chain and special guide bars that reduce the

risks associated with rotational kickback.

Use only the replacement guide bars and low

kickback chains specified by the manufacturer

for the saw.

CHAIN SAW SAFETY WARNINGS

 With a basic understanding of kickback, you

can reduce or eliminate the element of surprise.

Sudden surprise contributes to accidents.

 Do not overreach. Keep proper footing and

balance at all times.

 Do not cut above chest height or overreach

when cutting. Do not let the nose of the guide

bar contact a log, branch, ground, or any other

obstruction while you are operating the unit.

 Follow the sharpening and maintenance

instructions for the saw chain.

 Push and Pull – This reaction force is always

opposite to the direction the chain is moving

where wood contact is made. Thus, the operator

must be ready to control the PULL when cutting

on the bottom edge of the bar, and PUSH when

cutting along the top edge. See Figure 3.

UNDERSTANDING YOUR CHAIN SAW

SAFETY DEVICES

LOW KICKBACK SAW CHAIN

The rakers (depth gauges) ahead of each cutter

can minimize the force of a kickback reaction by

preventing the cutters from digging in too deeply

at the kickback zone. Only use replacement chain

that is equivalent to original chain or has been

certified as low kickback chain per ANSI B175.1.

Low kickback saw chain is chain that has met

the kickback performance requirements of ANSI

B175.1 (American National Standard for Power

Tools – Gasoline-Powered Chain Saws-Safety

Requirements) when tested on the representative

sample of chain saws below 3.8 c.i.d. specified in

ANSI B175.1.

As saw chains are sharpened during their useful

life, they lose some of the low kickback qualities

and extra caution should be used.

GUIDE BARS

Generally, guide bars with small radius tips have

somewhat lower kickback potentials.

When making a replacement, be sure to order

one of the bars listed for the saw in this operator’s

manual.

 Save these instructions. Refer to them frequently

and use them to instruct others who may use

this product. If you loan someone this product,

loan them these instructions also.

OPERATION

To remove:

Locate latches on side of battery pack and depress

both sides to release the battery pack from the

chain saw.

For complete charging instructions, see the opera-

tor’s manuals for your battery pack and charger.

NOTICE:

When placing battery pack in your chain saw,

be sure raised rib on battery pack aligns with

groove in chain saw’s battery port and latches

snap in place properly. Improper assembly of

battery pack can cause damage to internal

components.

CHAIN LUBRICATION SYSTEM

See Figure 6.

NOTICE:

Remove battery pack from unit. Fill oil tank with

RYOBI Bar and Chain Lubricant before starting

the chain saw. Failure to lubricate the chain will

cause damage to the bar and chain.

 Use RYOBI Bar and Chain Lubricant. It is formu-

lated to perform over a wide temperature range

with no dilution required.

NOTE: Do not use dirty, used or otherwise con-

taminated lubricants. Damage may occur to the

bar or chain.

 Carefully pour the bar and chain lubricant into

the tank.

 Check and fill the oil tank when battery is

recharged, or as needed.

Fig. 6

 Depress the oil tank cap once to pump the

lubricant to the chain before starting the saw.

 To keep the chain lubricated while cutting,

depress the oil tank cap once every few minutes.

NOTE: It is normal for lubricant to seep from the

saw when not in use. To prevent seepage, empty

the oil tank after each use. When storing the unit

for a long period of time (three months or longer) be

sure the chain is lightly lubricated; this will prevent

rust on the chain and bar sprocket.

NOTICE:

Before each use, check to make sure that the

chain is properly tensioned. A cold chain is cor-

rectly tensioned when there is no slack on the

underside of the guide bar, the chain is snug,

and it can be turned by hand without binding.

During normal saw operation, the temperature

of the chain increases. The drive links of a cor-

rectly tensioned warm chain will hang approxi-

mately .050 in. out of the bar groove.

See the Adjusting the Chain Tension instruc-

tions in the Maintenance section of this manual

to properly adjust the chain tension.

 Release the switch trigger to stop the chain saw.

 Upon release of the switch trigger, the lock-out

button will be automatically reset to the lock

position.

This cordless chain saw is not designed for cutting

trees larger than 7 in. in diameter.

This cordless chain saw is designed for limbing

and pruning type cutting, as well as cutting trees

up to 7 in. in diameter only.

PREPARATION FOR CUTTING

PROPER GRIP ON HANDLES

See Figures 8 - 10.

Refer to Important Safety Instructions earlier in this

manual for appropriate safety equipment.

 Wear non-slip gloves for maximum grip and

protection.

 Hold the saw firmly with both hands. Always

keep your left hand on the front handle and your

right hand on the rear handle so that your body

is to the left of the chain line.

WARNING:

Never use a left-handed (cross-handed) grip, or

any stance which would place your body or arm

across the chain line. Improper operation of the

chain saw could result in serious personal injury.

OPERATION

 Maintain a proper grip on the saw whenever

the unit is running. The fingers should encircle

the handle and the thumb is wrapped under the

handlebar. This grip is least likely to be broken

(by a kickback or other sudden reaction of the

saw). Any grip in which the thumb and fingers

are on the same side of the handle, is danger-

ous because a slight kick of the saw can cause

loss of control.

WARNING:

Do not operate the switch trigger with your left

hand and hold the front handle with your right

hand. Never allow any part of your body to be

in the chain line while operating a saw. Improper

operation of the chain saw could result in seri-

ous personal injury.

PROPER CUTTING STANCE

See Figure 11.

WARNING:

Alway use the proper cutting stance described

in this section. Never kneel when using the

chain saw except when felling a tree as shown

in figure 15. Kneeling could result in loss of sta-

bility and control of the saw resulting in serious

personal injury.

 Weight should be balanced with both feet on

solid ground.

 Keep left arm with elbow locked in a “straight

arm” position to withstand any kickback force.

 Your body should always be to the left of the

chain line.

 Thumb should be on underside of handlebar.

BASIC CUTTING PROCEDURE

Practice cutting a few small logs using the following

technique to get the “feel” of using the saw before

you begin a major sawing operation.

 Support log on a saw horse or cradle.

 Take the proper stance in front of the wood with

the saw off.

 Squeeze the switch trigger and let the chain

accelerate to full speed before entering the cut.

 Begin cutting with the saw against the log.

 Keep the unit running the entire time you are

cutting, maintain a steady speed.

 Allow the chain to cut for you; exert only light

downward pressure. If you force the cut, dam-

age to the bar, chain, or unit can result.

CHAIN LINE

 Release the switch trigger as soon as the cut

is completed, allowing the chain to stop. If you

run the saw without a cutting load, unnecessary

wear can occur to the chain, bar, and unit.

 Do not put pressure on the saw at the end of cut.

WORK AREA PRECAUTIONS

 Cut only wood or materials made from wood,

no sheet metal, no plastics, no masonry, no

non-wood building materials.

18 - English

 Never allow children to operate the saw. Allow

no person to use this chain saw who has not

read this Operator’s Manual or received ade-

quate instructions for the safe and proper use

of this chain saw.

 Keep everyone - helpers, bystanders, children,

and animals - a safe distance from the cutting

area. During felling operations, the safe dis-

tance should be a least twice the height of the

largest trees in the felling area. During bucking

operations, keep a minimum distance of 15 feet

between workers.

 Always cut with both feet on solid ground to

prevent being pulled off balance.

 Do not cut above chest height, as a saw held high-

er is difficult to control against kickback forces.

 Do not fell trees near electrical wires or build-

ings. Leave this operation for professionals.

 Cut only when visibility and light are adequate

for you to see clearly.

FELLING TREES

See Figures 12 - 15.

HAZARDOUS CONDITIONS

WARNING:

Do not fell trees during periods of high wind or

heavy precipitation. Wait until the hazardous

weather has ended.

WARNING:

Closely check for broken or dead branches,

which could fall while cutting and do not cut

near buildings or electrical wires if you do not

know the direction of tree fall. Do not cut at

night or during bad weather conditions, such as

rain, snow, or strong winds, which can reduce

visibility and control of the chain saw. If the tree

you are felling makes contact with any utility

line, you should discontinue use of the chain

saw and immediately notify the utility company.

Failure to follow these instructions could result

in death or serious personal injury.

When felling a tree, it is very important that you

closely follow these warnings and instructions to

prevent possible death or serious personal injury.

OF FALL

RETREAT PATH

■Do not cut down trees having an extreme lean or

large trees with rotten limbs, loose bark, or hol-

low trunks. Have these trees pushed or dragged

down with heavy equipment, then cut them up.

■Do not cut trees near electrical wires or buildings.

■Check the tree for damaged or dead branches

that could fall and hit you during felling.

■Periodically glance at the top of the tree during

the backcut to assure the tree is going to fall in

the desired direction.

If the tree starts to fall in the wrong direction,

or if the saw gets caught or hung up during the

fall, leave the saw and save yourself!



Felling a tree - When bucking and felling opera-

tions are being performed by two or more per-

sons, at the same time, the felling operation

should be separated from the bucking operation

by a distance of at least twice the height of the

tree being felled. Trees should not be felled in a

manner that would endanger any person, strike

any utility line or cause any property damage. If

the tree does make contact with any utility line, the

utility company should be notified immediately.

 Before any cuts are started, pick your escape

route (or routes in case the intended route is

blocked); clear the immediate area around the

19 - English

OPERATION

tree and make sure there are no obstructions in

your planned path of retreat. Clear paths of safe

retreat should extend back and diagonally (45°)

to the rear of the planned line of fall. When the

tree begins to fall, you should retreat away from

the direction of fall along a retreat path and at

least 20 feet away from the trunk in case it kicks

back over the stump. See Figure 12.

 Before felling is started, consider the force and

direction of the wind, the lean and balance of

the tree, and the location of large limbs. These

things influence the direction in which the tree

will fall. Do not try to fell a tree along a line dif-

ferent from its natural line of fall.

 The chain saw operator should keep on the

uphill side of the terrain as the tree is likely to

roll or slide downhill after it is felled.

 Remove dirt, stones, loose bark, nails, staples,

and wire from the tree where felling cuts are to

be made.

 Notched Undercut. Cut a notch about 1/3 the

diameter of the tree, perpendicular to the direc-

tion of fall. Make the cuts of the notch so they

intersect at a right angle to the line of fall. This

notch should be cleaned out to leave a straight

line. To keep the weight of the wood off the saw,

always make the lower cut of the notch before

the upper cut. See Figure 13.

 Felling Backcut. The backcut is always made

level and horizontal, and at a minimum of 2 in.

above the horizontal cut of the notch. See Fig-

ures 13 - 14.

 Never cut through to the notch. Always leave a

band of wood between the notch and backcut

(approximately 2 in. or 1/10 the diameter of the

tree). This is called “hinge” or “hingewood.” It

controls the fall of the tree and prevents slip-

ping or twisting or shoot-back of the tree off the

stump. See Figures 13 - 14.

 On large diameter trees, stop the back cut

before it is deep enough for the tree to either

fall or settle back on the stump. Then insert

soft wooden or plastic wedges into the cut so

they do not touch the chain. The wedges can

be driven in, little by little, to help jack the tree

over. See Figure 15.



As tree starts to fall, stop the chain saw and put

it down immediately. Retreat along the cleared

path, but watch the action in case something

falls your way. Be alert for overhead limbs or

branches that may fall and watch your footing.

WARNING:

Never cut through to the notch when making a

backcut. The hinge controls the fall of the tree,

this is the section of wood between the notch

and backcut.

20 - English

OPERATION

BUCKING

See Figures 16 - 19.

Bucking is the term used for cutting a fallen tree

to the desired log length.

 Always make sure your footing is secure and

your weight is distributed evenly on both feet.

■ Cut only one log at a time.

■ Support small logs on a saw horse or another

log while bucking.

■ Keep a clear cutting area. Make sure that no

objects can contact the guide bar nose and

chain during cutting, this can cause kickback.

Refer to Kickback earlier in this manual.

■When bucking on a slope, always stand on the

uphill side of the log. To maintain complete con-

trol of the chain saw when cutting through the

log, release the cutting pressure near the end of

the cut without relaxing your grip on the chain

saw handles. Do not let the chain contact the

ground. After completing the cut, wait for the

saw chain to stop before you move the chain

saw. Always stop the motor before moving from

tree to tree.

BUCKING LOGS UNDER STRESS

See Figures 18 - 19.

When the log is supported along its entire length,

it should be cut from the top or overbucking.

When the log is supported on one end, cut 1/3

the diameter from the underside or underbuck-

ing. Then make the finishing cut by overbucking

to meet the first cut.

As the log is being cut, it will tend to bend. The saw

can become pinched or hung in the log if you make

the first cut deeper than 1/3 of the diameter of the log.

Give special attention to logs under stress to pre-

vent the bar and chain from pinching.
