GENERAL SAFETY RULES
WARNING:
Do not attempt to operate this unit until you
have read thoroughly and understand completely 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 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.
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, or under the influence of alcohol, drugs, or
medication.
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 stopped and the guide bar and saw
chain positioned to the rear. When transporting
your chain saw, use the appropriate guide bar
scabbard.
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. Do
not leave the unit running unattended.
To avoid accidental starting, never carry the unit
with your finger on the 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.
3 - English
Inspect the battery charger cord periodically,
and if damaged, have it replaced or repaired by
an authorized service dealer.
Keep handles dry, clean, and free of oil and
grease.
Do not operate a chain saw that is damaged,
improperly adjusted, or not completely and
securely assembled. Chain should stop turning
when the trigger is released. If the chain turns
after the trigger has been released, have the unit
serviced by your nearest Ryobi service dealer.
Check for damaged parts. Any part or guard that
has been damaged should be carefully checked
to determine that it will operate properly and
perform its intended function. 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
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 Ryobi
service dealer.
Do not use in the rain, snow or wet condi-
tions.
Always maintain a proper stance. Do not over-
reach.
Do not adapt your powerhead to a bow guide
or use it to power any attachments or devices
not listed for the saw.
Do not cut vines and/or small underbrush.
SAFETY APPAREL
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 nonslip 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.
GENERAL SAFETY RULES
Wear eye protection which is marked to comply
with ANSI Z87.1 as well as hearing and head
protection when operating this equipment.
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:
1. Hold the saw firmly with both hands when
the motor 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.
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 at full speed.
Fully squeeze the throttle trigger and maintain
a steady cutting speed.
4. Use replacement parts such as low kick-
back chain, SAFE-T-TIP
guards and special guide bars that reduce the
risks associated with rotational kickback.
®
anti-kickback nose
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.
Keep proper footing and balance at all times.
Do not cut above shoulder height or overreach when
cutting.
®
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.
IN THE CUTTING/WORK AREA
Do not operate a chain saw in a tree, on a ladder,
rooftop or scaffold; this is extremely dangerous.
Keep ALL children, bystanders, visitors, and
animals out of the work area while starting or
cutting with the chain saw.
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.
Never start cutting until you have a clear work
area, secure footing, and a planned retreat path
from the falling tree. Cluttered area invite injuries.
Do not expose the chain saw to rain.
Do not use the chain saw in damp or wet loca-
tions.
Do not use the chain saw near flammable liq-
uids, gases, or in any type of explosive atmosphere.
Use extreme caution when cutting small size
brush and saplings, because slender mate-
4 - English
GENERAL SAFETY RULES
rial 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 per-
formed 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 materials.
Do not use the chain saw for purposes not
intended.
Store idle 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, remove battery and place the scabbard on
the bar and chain or store the chain saw in a
carry case.
Remove the battery pack from the chain saw
before cleaning, servicing, storing, removing
material from the unit, changing accessories
such as the bar and chain, or when not in use.
UNDERSTANDING YOUR CHAIN SAW
SAFETY DEVICES
See Figure 4.
®
SAFE-T-TIP
The SAFE-T-TIP
pening, because it covers the tip of the bar where
kickback is generated. Never attempt any kind of
Anti-Kickback Nose Guard
®
prevents kickback from hap-
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 saw chain is chain that has met
the kickback performance requirements of ANSI
B175.1 - 1991 (American National Standard for
Power Tools - Gasoline-Powered Chain SawsSafety 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 Ryobi 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®.

SPECIFIC SAFETY RULES
BATTERY SAFETY
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
before cleaning, servicing, storing, removing
material from the unit, changing accessories
such as the bar and chain, or when not in use.
A battery pack must be recharged only with the
specified charger for the battery pack. A charger
that may be suitable for one type of battery pack
may create a risk of fire when used with another
battery pack. Use battery pack only with charger
listed.
For use with 18V nickel-cadmium and 18 V
lithium-ion battery packs, see tool/appliance/
battery pack/charger correlation supplement
987000-432.
To reduce the risk of explosion and possible
injury, Do not place battery units or their batteries
near fire or heat.
Do not open or mutilate the battery pack.
Released electrolyte is corrosive and may cause
damage to the eyes or skin. It may be toxic if
swallowed.
Do not crush, drop or damage battery pack. Do
not use a battery pack or charger that has been
dropped or received a sharp blow. A damaged
battery is subject to explosion. Properly dispose
of a dropped or damaged battery immediately.
Batteries can explode in the presence of a
source of ignition, such as a pilot light. To reduce
the risk of serious personal injury, never use any
cordless product in the presence of open flame.
An exploded battery pack can propel debris and
chemicals. If exposed, flush with water immediately.
Do not charge unit in a damp or wet location.
Following this rule will reduce the risk of electric
shock.
For best results, your battery unit should be
charged in a location where the temperature
is more than 50°F but less than 100°F. Do not
store outside or in vehicles.
Under extreme usage or temperature conditions,
battery pack leakage may occur. If liquid comes
in contact with your skin, wash immediately with
soap and water, then neutralize with lemon juice
or vinegar. If liquid gets into your eyes, flush
them with clean water for at least 10 minutes,
then seek immediate medical attention.
Do not dispose of batteries in a fire. The cell
may explode. Batteries should be recycled, consult your local waste authority for information
regarding available recycling and/or disposal
options.
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 pack terminals
together may cause sparks, burns, or a fire.

CAUTION:
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.
OPERATION
CHAIN OIL SYSTEM
See Figure 7.
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 oils. Damage may occur to the bar or
chain.
Carefully pour the bar and chain oil into the
tank.
Check and fill the oil tank when battery is
recharged, or as needed.
Depress the oil tank cap several times to pump
the oil to the chain before starting the saw.
Depress the oil tank cap every 20-30 seconds
while cutting to keep the chain lubricated.
NOTE: It is normal for oil 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.

PREPARATION FOR CUTTING
PROPER GRIP ON HANDLES
See Figures 9 - 11.
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.
STARTING AND STOPPING THE CHAIN
SAW
See Figure 8.
WARNING:
Keep body to the left of the chain line. Never
straddle the saw or chain, or lean over past the
chain line.
Starting the chain saw:
Place the chain saw on a flat bare surface and
make sure no objects or obstructions are in
immediate vicinity which could come in contact
with the bar and chain.
Press and hold the trigger lock-out button. This
makes the trigger operational.
Press and hold the trigger, release the trigger
lock-out button and continue to squeeze the
trigger for continued operation.
Stopping the chain saw:
Release the trigger to stop the chain saw.
Upon release of the trigger, the trigger lock-out
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 dangerous because a slight kick of the saw can cause
loss of control.
WARNING:
Do not operate the throttle 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.
11 - English
OPERATION
PROPER CUTTING STANCE
See Figure 12.
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 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, damage to the bar, chain, or unit can result.
Release the trigger as soon as the cut is com-
pleted, 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
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.
When felling a tree, 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 fell-
ing area. During bucking operations, keep a
minimum distance 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
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.
TREE FELLING
See Figures 13-16.
Unusual Hazardous Tree Felling Conditions
Do not fell trees during periods of high wind or
heavy precipitation. Wait to do your cutting until
the hazard has ended.
WARNING:
Do not cut down trees having an extreme lean
or large trees that have rotten limbs, loose bark,
or hollow trunks. Have these trees pushed or
dragged down with heavy equipment, then cut
them up.
DANGER:
Electrocution hazard. Do not cut trees or
branches near power lines or electrical wires.
Contact with power lines or live electrical wires
will result in serious personal injury or possible
death.
WARNING:
Do not cut trees or branches near buildings,
which may result in serious injuries or property
damage.
12 - English
OPERATION
WARNING:
Check the tree for damaged or dead branches
that could fall and hit you during felling.
WARNING:
Periodically glance at the top of the tree during
the backcut to assure the tree is going to fall in
the desired direction.
WARNING:
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 operations are being performed by two or more persons, 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 path of
safe retreat approximately 135° from planned
line of fall. The retreat path should extend back
and diagonally to the rear of the expected line
of fall. 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 different 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 direction 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 Fig-
ures 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 slipping 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.
NOTE: 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 the cut is complete,
the tip should be reinstalled 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. 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.
13 - English
OPERATION
BUCKING
See Figures 17 - 20.
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
kickback device attached while cutting. Refer to
Precautions Against 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.
Sometimes it is impossible to avoid pinching
(with just standard cutting techniques) or difficult
to predict which way a log will settle when cut.
To avoid pinching while cutting, rotate or move
the log so that the pinch is eliminated.
®
anti-
BUCKING LOGS UNDER STRESS
See Figures 19 - 20.
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 underbucking. 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 prevent the bar and chain from pinching.
When bucking on a slope, always stand on the
uphill side of the log as shown in figure 18. When
“cutting through,” to maintain complete control
of the chain saw, 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.
TYPES OF CUTTING USED
See Figure 20.
OVERBUCKING
Begin on the top side of the log with the bottom
of the saw against the log; exert light pressure
downward. Note that the saw will tend to pull
away from you.
UNDERBUCKING
Begin on the under side of the log with the top
of the saw against the log; exert light pressure
upward. During underbucking, the saw will tend
to push back at you. Be prepared for this reaction
and hold the saw firmly to maintain control.
WARNING:
Never climb into a tree to limb or prune. Do not
stand on ladders, platforms, a log, or in any
position which can cause you to lose your balance or control of the saw.
LIMBING
See Figure 21.
Limbing is removing branches from a fallen tree.
Work slowly, keeping both hands on the chain
saw with a firm grip. Always make sure your
footing is secure and your weight is distributed
evenly on both feet.
Leave the larger support limbs under the tree to
keep the tree off the ground while cutting.
14 - English
OPERATION
Limbs should be cut one at a time. Remove the
cut limbs from the work area often to help keep
the work area clean and safe.
Branches under tension should be cut from the
bottom up to avoid binding the chain saw.
Keep the tree between you and the chain saw
while limbing. Cut from the side of the tree
opposite the branch you are cutting.
PRUNING
See Figure 22.
Pruning is trimming limbs from a live tree.
Work slowly, keeping both hands on the chain
saw with a firm grip. Always make sure your
footing is secure and your weight is distributed
evenly on both feet.
Do not cut from a ladder, this is extremely dan-
gerous. Leave this operation for professionals.
Do not cut above chest height as a saw held
higher is difficult to control against kickback.
When pruning trees it is important not to make
the finishing cut next to the main limb or trunk
until you have cut off the limb further out to
reduce the weight. This prevents stripping the
bark from the main member.
Now make your finishing cut smoothly and
neatly against the main member so the bark will
grow back to seal the wound.
WARNING:
If the limbs to be pruned are above chest height,
hire a professional to perform the pruning.
SPRINGPOLES
See Figure 23.
A springpole is any log, branch, rooted stump, or
sapling which is bent under tension by other wood
so that it springs back if the wood holding it is cut
or removed. On a fallen tree, a rooted stump has
a high potential of springing back to the upright
position during the bucking cut to separate the log
from the stump. Watch out for springpoles, they
are dangerous.
WARNING:
Springpoles are dangerous and could strike the
operator, causing the operator to lose control
of the chain saw. This could result in severe or
fatal injury to the operator.
Underbuck the branch 1/3 through for your first
cut.
Your second cut should overbuck to drop the
branch off.
