GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions
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.
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.

GENERAL POWER TOOL SAFETY WARNINGS
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.
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.
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.
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.

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 safety glasses and hearing protection.
Further protective equipment for head, hands,
legs and feet is recommended. Adequate
protective clothing will reduce personal injury
by flying debris or accidental contact with the
saw chain.
Do not operate a chain saw in a tree. Operation
of a chain saw while up in a tree may result in
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.
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 accessories.
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
Keep handles dry, clean, and free from oil
and grease. Greasy, oily handles are slippery
causing loss of control.
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.
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.
6 - English
CHAIN SAW SAFETY WARNINGS
Do not overreach and do not cut above
shoulder 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.
 It is not recommended to cut over chest height.
 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.
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.
7 - English
CHAIN SAW SAFETY WARNINGS
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 your an authorized
service center.
Always maintain a proper stance.
Do not use chain saw if switch does not turn it
on and off. Have defective switch replaced by
an 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, scaffold, or other unstable support; 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.
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 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 battery only with charger listed. For use
with 18V nickel-cadmium and 18V lithium-ion
battery packs, see 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,
servicing, storing, removing material from the
unit, changing accessories such as the bar and
chain, or when not in use.
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.

CHAIN SAW SAFETY WARNINGS
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 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.
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 kick-
back chain, chain brakes 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.
With a basic understanding of kickback, you
can reduce or eliminate the element of surprise.
Sudden surprise contributes to accidents.

CHAIN SAW SAFETY WARNINGS
Keep proper footing and balance at all times.
Do not cut above chest height or overreach
when cutting.
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.

OPERATION
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.
Turn saw on its side and remove chain oil tank
cap.
Carefully pour the bar and chain lubricant into
the tank.
Wipe off excess lubricant.
Check and fill the oil tank when battery is
recharged, or as needed.
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.

OPERATION
PREPARATION FOR CUTTING
PROPER GRIP ON HANDLES
See Figures 8 - 10.
Refer to Chain Saw Safety Warnings 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.
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 - 12.
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 12. 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.
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.
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.
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.
When felling a tree, keep everyone - helpers,
bystanders, children, and animals - a safe dis-
tance from the cutting area. During felling opera-
tions, the safe distance should be a least twice
the height of the largest trees in the felling area.
During bucking opetations, keep a minimum dis-
tance of 15 feet between workers. 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.
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.
