GENERAL SAFETY RULES

WARNING:

Do not attempt to operate this unit until you

have read thoroughly and understand com-

pletely all instructions, safety information, etc.

contained in this manual. Failure to comply can

result in accidents involving fire, electric shock,

or serious personal injury.

READ ALL INSTRUCTIONS

BASIC SAFETY PRECAUTIONS

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 atmo-

spheres, such as in the presence of flammable

liquids, gases, or dust. Chain saws create

sparks which may ignite the dust or fumes.

WARNING: Use outdoor extension cords

marked SW-A, SOW-A, STW-A, STOW-A,

SJW-A, SJTW-A, or SJTOW-A. These cords

are rated for outdoor use and reduce the risk

of electric shock.

Polarized Plugs. To reduce the risk of electric

shock, this tool has a polarized plug (one blade

is wider than the other). This plug will fit in a

polarized outlet only one way. If the plug does

not fit fully in the outlet, reverse the plug. If it

still does not fit, contact a qualified electrician

to install the proper outlet. Do not change the

plug in any way.

Make sure your extension cord is in good condi-

tion. When using an extension cord, be sure to

use one heavy enough to carry the current your

product will draw. A wire gauge size (A.W.G.)

of at least 14 is recommended for an extension

cord 50 feet or less in length. A cord exceeding

100 feet is not recommended. If in doubt, use

the next heavier gauge. The smaller the gauge

number, the heavier the cord. An undersized

cord will cause a drop in line voltage resulting

in loss of power and overheating.

Inspect extension cords periodically and, if

damaged, have repaired by a licensed electri-

cian. Constantly stay aware of cord location.

Following this rule will reduce the risk of electric

shock or fire.

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.

Always be aware of extension cord while oper-

ating chain saw. Take precautions to avoid

tripping over cord. Keep cord away from chain

and operator at all times. Never carry saw by

the cord or pull it to disconnect from receptacle.

Keep cord from oil and sharp edges.

Stay alert and pay attention to what you are

doing. Use common sense when using this unit.

Keep all parts of your body away from the saw

chain when the unit is running.

Always carry the chain saw by the front handle

with the unit unplugged and the guide bar

and saw chain positioned to the rear. When

transporting your chain saw, use the appropriate

guide bar scabbard.

Page 4 — English

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.

Keep handles dry, clean, and free of oil and

grease.

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 opera-

tor, 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

your nearest Homelite service dealer.

Check for damaged parts. Check for alignment

of moving parts, binding of moving parts, break-

age of parts, mounting, and any other condi-

tions that may affect its operation. A guard or

other part that is damaged should be properly

repaired or replaced by an authorized service

dealer 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 your nearest Homelite

service dealer.

Always maintain a proper stance.

GENERAL SAFETY RULES

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

on and off. Have defective switch replaced by

authorized service center.

Do not adapt your powerhead 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 operate a chain saw in a tree, on a ladder,

rooftop, or scaffold; this is extremely dangerous.

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.

Use extreme caution when cutting small size

brush and saplings, because small material may

catch the saw chain and be whipped toward you

or pull you off balance.

When cutting a limb that is under tension, be

alert for spring back so that you will not be

struck when the tension in the wood fibers is

released.

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

performed better and safer at the rate for which

it was intended.

Always use the right product for your applica-

tion. The chain saw should be used for cutting

wood only. Never use the chain saw to cut

plastic, masonry or non-wood building materi-

als.

Do not use the chain saw for purposes not

intended.

Store chain saw 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 and store the chain saw in carrying case.

Save these instructions. Refer to them fre-

quently and use them to instruct others who

may use this product. If you loan someone this

product, loan them these instructions also.

PURPOSES ONLY

KICKBACK

See Figures 1 - 2.

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 cut-

ting jobs free from accident or injury.

The following precautions should be followed

to minimize kickback:

1. 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 encircl-

ing the chain saw handles. A firm grip together

with a stiff left arm will help you maintain

control of the saw if kickback occurs.

2. Make sure that the area in which you are cut-

ting 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.

3. Always cut with the unit running. Fully

squeeze the switch trigger and maintain

cutting speed.

4. Use replacement parts such as low kickback

chain, SAFE-T-TIP

®

anti-kickback nose

guards 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 manufac-

turer for the saw.

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 shoulder height or overreach

when cutting. Do not let nose of guide bar con-

tact log, branch, ground, or other obstruction.

Keep the SAFE-T-TIP

®

anti-kickback nose guard

properly mounted on the guide bar to prevent

rotational kickback.

Follow the sharpening and maintenance instruc-

tions 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

See Figure 4.

SAFE-T-TIP

®

ANTI-KICKBACK NOSE

GUARD

The SAFE-T-TIP

®

prevents rotational kickback

from happening, because it covers the tip of the

bar where kickback is generated. Never attempt

any kind of cutting where the SAFE-T-TIP

®

would

have to be removed from the bar tip.

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/skip tooth saw chain is a chain that

has met the kickback performance requirements

of ANSI B175.1 - 1991 (American National Stan-

dard 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 - 1991.

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 Homelite bars listed for the saw in this

operator’s manual. The proper size SAFE-T-TIP

®

nose guard comes installed on the bar. Use only

guide bars that have a provision for mounting the

SAFE-T-TIP

Before using any extension cord, inspect it for loose

or exposed wires and cut or worn insulation.

A proper extension cord is available at an authorized

service center.

It is possible to tie the extension cord and power

cord in a knot to prevent them from becoming

disconnected during use. Make the knot as shown

in figure 5, then connect the plug end of the power

cord into the receptacle end of the extension cord.

This method can also be used to tie two extension

cords together.

DOUBLE INSULATION

Double insulation is a concept in safety in electric

power tools, which eliminates the need for the usual

three-wire grounded power cord. All exposed metal

parts are isolated from the internal metal motor

components with protecting insulation. Double

insulated tools do not need to be grounded.

WARNING:

The double insulated system is intended to

protect the user from shock resulting from a

break in the tool’s internal insulation. Observe

all normal safety precautions to avoid electrical

shock.

NOTE: Servicing of a product with double insulation

requires extreme care and knowledge of the system

and should be performed only by a qualified service

technician. For service, we suggest you return the

product to your nearest authorized service center

for repair. Always use original factory replacement

parts when servicing.

ELECTRICAL CONNECTION

This product has a precision-built electric motor.

It should be connected to a power supply that is

120V, AC only (normal household current), 60

Hz. Do not operate this product on direct current

(DC). A substantial voltage drop will cause a loss of

power and the motor will overheat. If the product

does not operate when plugged into an outlet,

double-check the power supply.

EXTENSION CORDS

See Figure 5.

When using a power tool at a considerable

distance from a power source, be sure to use

an extension cord that has the capacity to

handle the current the product will draw. An

undersized cord will cause a drop in line voltage,

resulting in overheating and loss of power. Use the

chart to determine the minimum wire size required

in an extension cord. Only round jacketed cords

listed by Underwriter’s Laboratories (UL) should

be used.

When working outdoors with a product, use an

extension cord that is designed for outside use.

This type of cord is designated with “W-A” or “W”

on the cord’s jacket.

PROPER GRIP ON HANDLES

See Figure 10.

See General Safety Rules 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 that would place your body or arm

across the chain line.

Maintain a proper grip on the saw whenever the

motor 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 dangerous

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:

Always use the proper cutting stance described

in this section. Never kneel when using the

chain saw, except when felling a tree as illus-

trated in Figure 12. Kneeling could result in

loss of stability and control of the chain saw,

resulting in serious personal injury.

Page 17 — English

OPERATION

Fig. 12

Balance your weight with both feet on solid

ground.

Keep left arm with elbow locked in a “straight

arm” position to withstand any kickback force.

Keep your body to the left of the chain line.

Keep your thumb on underside of handlebar.

BASIC OPERATING/CUTTING

PROCEDURES

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.

Take the proper stance in front of the wood with

the saw idling.

Press the switch lock-out and squeeze the

switch trigger then release switch lock-out 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. Forcing the cut could result

in damage to the bar, chain, or motor.

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

the cut.

WORK AREA PRECAUTIONS

See Figure 12.

Cut only wood or materials made from wood;

no sheet metal, no plastics, no masonry, no

non-wood building materials.

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

adequate 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

distance 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 shoulder height as a saw held

higher 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 13 - 16.

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 important that you follow

these warnings and instructions to prevent possible

serious injury.

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

or large trees with rotten limbs, loose bark,

or hollow 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

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 13.

 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.

SECTION

Fig. 17

 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 14.



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 Figures 14 - 15.

 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 14 - 15.

 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 16.

 When bucking or felling with a wedge, it may

be necessary to remove the SAFE-T-TIP anti-

kickback device to allow the bar to be drawn

through the cut. After you complete the cut,

reinstall the tip immediately.

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.

WARNING:

Never cut through to the notch when making a

back cut. The hinge controls the fall of the tree,

this is the section of wood between the notch

and backcut.

REMOVING BUTTRESS ROOTS

See Figure 17.

A buttress root is a large root extending from the

trunk of the tree above the ground. Remove large

buttress roots prior to felling. Make the horizontal

cut into the buttress first, followed by the vertical

cut. Remove the resulting loose section from the

work area. Follow the correct tree felling procedure

as stated in Proper Procedure For Tree Felling

after you have removed the large buttress roots.

BUCKING

See Figure 18.

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.

To avoid the danger, keep the SAFE-T-TIP anti-

kickback device attached while cutting. Refer

to Kickback earlier in this manual.

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

uphill side of the log. To maintain complete

control 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 WITH A WEDGE

See Figure 19.

If the wood diameter is large enough for you to

insert a soft bucking wedge without touching the

chain, you should use the wedge to hold the cut

open to prevent pinching.

NOTE: When bucking or felling with a wedge, you

may need to remove the SAFE-T-TIP anti-kickback

device to allow the bar to be drawn through the

cut. After you complete the cut, reinstall the tip.

BUCKING LOGS UNDER STRESS

See Figure 20.

Make the first bucking cut 1/3 of the way through

the log and finish with a 2/3 cut on the opposite

side. As you cut the log, 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

prevent the bar and chain from pinching.
