general SAFETY RULES
WARNING:
Read and understand all instructions. Failure
to follow all instructions listed below may result
in electric shock, fire, and/or serious personal
injury.
READ ALL INSTRUCTIONS
Basic Safety Precautions
nDo 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.
nAlways 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.
nStay alert and pay attention to what you are
doing. Use common sense when using this unit.
nKeep all parts of your body away from the saw
chain when the unit is running.
nAlways 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.
nNever 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.
nBefore you start the unit, make sure the saw
chain is not contacting any object.
nStop the chain saw before setting it down. Do
not leave the unit running unattended.
n To avoid accidental starting, never carry the unit
with your finger on the switch trigger.
nMaintain 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.
Inspect the battery charger cord periodically,
and if damaged, have it replaced or repaired by
an authorized service dealer.
nKeep handles dry, clean, and free of oil and
grease.
nDo not operate a chain saw that is damaged,
improperly adjusted, or not completely and
securely assembled. Chain should stop turning
when the switch trigger is released. If the chain
turns after the switch trigger has been released,
have the unit serviced by your nearest Ryobi
service dealer.
n 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.
n All chain saw service, other than the items listed
in the operation and maintenance sections,
should be performed by your nearest Ryobi
service dealer.
nDo not use in the rain, snow or wet conditions.
nAlways maintain a proper stance. Do not overreach.
nDo not adapt your powerhead to a bow guide
or use it to power any attachments or devices
not listed for the saw.
nDo not cut vines and/or small underbrush.
SAFETY APPAREL
nWear 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.
nAlways wear eye protection with side shields
marked to comply with ANSI Z87.1, along with
head protection.
3 - English
general SAFETY RULES
Kickback
See Figures 1 - 4.
nWARNING: 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.
nThe 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 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.
3. Always cut with the unit running at full speed.
Fully squeeze the switch trigger and maintain
a steady 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 manufacturer
for the saw.
nWith a basic understanding of kickback, you
can reduce or eliminate the element of surprise.
Sudden surprise contributes to accidents.

general SAFETY RULES
nKeep proper footing and balance at all times.
nDo not cut above shoulder height or overreach
when cutting.
nKeep the SAFE-T-TIP® anti-kickback nose guard
properly mounted on the guide bar to prevent
rotational kickback.
nFollow the sharpening and maintenance instructions for the saw chain.
nPush 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 4.
In The Cutting/Work Area
n Do not operate a chain saw in a tree, on a ladder,
rooftop or scaffold; this is extremely dangerous.
nKeep 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.
nNever start cutting until you have a clear work
area, secure footing, and a planned retreat path
from the falling tree. Cluttered area invite injuries.
nDo not expose the chain saw to rain.
n Do not use the chain saw in damp or wet locations.
nDo not use the chain saw near flammable liquids, gases, or in any type of explosive atmosphere.
nUse extreme caution when cutting small size
brush and saplings, because slender material may catch the saw chain and be whipped
toward you or pull you off balance.
nWhen 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.
n Do not force the chain saw. The job can be performed better and safer at the rate for which it
was intended.
nAlways 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.
nDo not use the chain saw for purposes not
intended.
n 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.
nRemove 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
SAFE-T-TIP® Anti-Kickback Nose
Guard
See Figure 1.
The SAFE-T-TIP® prevents 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 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.
5 - English
general SAFETY RULES
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
n 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.
nRemove 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.
nUse only with charger listed. For use with 40V
lithium-ion battery packs, see tool/appliance/
battery pack/charger correlation supplement
988000-842.
nSave these instructions. Refer to them frequently and use them to instruct others who
may use this tool. If you loan someone this tool,
loan them these instructions also.

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.

OPERATION
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.
Proper Cutting Stance
See Figures 12 - 13.
Fig. 10
WARNING:
Always use the proper cutting stance described
in this section. Never kneel when using the
chain saw, except when felling a tree as illustrated in Figure 13. Kneeling could result in loss
of stability and control of the chain 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, damage 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.

 Cut only wood or materials made from wood, no
sheet metal, no plastics, no masonry, no nonwood 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 felling 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 buildings.
Leave this operation for professionals.
 Cut only when visibility and light are adequate for
you to see clearly.

OPERATION
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.
n
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.
n
Do not cut trees near electrical wires or buildings.
n
Check the tree for damaged or dead branches
that could fall and hit you during felling.
n
Periodically glance at the top of the tree during
the backcut to assure the tree is going to fall in
the desired direction.
n
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
wedge

Fig. 19
line of fall. The retreat path should extend back
and diagonally to the rear of the expected line
of fall. See Figure 14.
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.
17 - English
OPERATION
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 15.
 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 15 - 16.
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 15 - 16.
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 17.
NOTE: When bucking or felling with a wedge, it
may be necessary to remove the SAFE-T-TIP®
anti-kickback nose guard 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.

OPERATION
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.

BUCKING Logs Under Stress
See Figures 20 - 21.
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 21.
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.

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 22.
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.
 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.
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
19 - English
OPERATION
Keep the tree between you and the chain saw
while limbing. Cut from the side of the tree
opposite the branch you are cutting.
SPRINGPOLE
Pruning
See Figure 23.
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 dangerous. 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.
 Underbuck the branch 1/3 through for your first cut.
Your second cut should overbuck to drop the
branch off.
Now make your finishing cut smoothly and
neatly against the main member so the bark will
grow back to seal the wound.
WARNING:
Fig. 24
Springpoles
See Figure 24.
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.
If the limbs to be pruned are above chest height,
hire a professional to perform the pruning. Failure to do so could result in serious personal
injury.

Chain Maintenance
See Figures 33 - 35.
WARNING:
Remove the battery pack and make sure the chain
has stopped before you do any work on the saw.
Use only low-kickback chain on this saw. This
fast-cutting chain will provide kickback reduction
when properly maintained.
For smooth and fast cutting, chain needs to be
maintained properly. The chain requires sharpen-
Fig. 35
ing when the wood chips are small and powdery,
the chain must be forced through the wood during cutting, or the chain cuts to one side. During
maintenance of your chain, consider the following:
Improper filing angle of the side plate can
increase the risk of a severe kickback.
Raker (depth gauge) clearance.
Too low increases the potential for kickback.
Not low enough decreases cutting ability.
 If cutter teeth have hit hard objects such as nails
and stones, or have been abraded by mud or sand
on the wood, have service dealer sharpen chain.
NOTE: Inspect the drive sprocket for wear or damage when replacing the chain. If signs of wear or
damage are present in the areas indicated, have the
drive sprocket replaced by a Ryobi Service dealer.
24 - English
MAINTENANCE
How to Sharpen the Cutters
See Figures 36 - 37.
Be careful to file all cutters to the specified angles
and to the same length, as fast cutting can be
obtained only when all cutters are uniform.
Wear gloves for protection. Properly tension
the chain prior to sharpening. Refer to Chain
Tension Section earlier in this manual. Do all
of your filing at the mid-point of the bar.
Use a 5/32 in. diameter round file and holder.
 Keep the file level with the top plate of the tooth.
Do not let the file dip or rock.
 Using light but firm pressure, stroke towards the
front corner of the tooth.
 Lift file away from the steel on each return stroke.
 Put a few firm strokes on every tooth. File all left
hand cutters in one direction. Then move to the
other side and file the right hand cutters in the
opposite direction. Occasionally remove filings
from the file with a wire brush.
WARNING:
Improper chain sharpening increases the potential of kickback.

DEPTH GAUGE JOINTER
Depth Gauge Clearance
See Figures 40 - 41.
The depth gauge should be maintained at a
clearance of .025 in. Use a depth gauge tool
for checking the depth gauge clearances.
Every time the chain is filed, check the depth
gauge clearance.
Use a flat file and a depth gauge jointer to lower
all gauges uniformly. Depth gauge jointers are
available in .020 in. to .035 in. Use a .025 in. depth
gauge jointer. After lowering each depth gauge,
restore original shape by rounding the front. Be
careful not to damage adjoining drive links with
the edge of the file.
Depth gauges must be adjusted with the flat file in
the same direction the adjoining cutter was filed
with the round file. Use care not to contact cutter
face with flat file when adjusting depth gauges.
GUIDE BAR MAINTENANCE
When the guide bar shows signs of wear, reverse
it on the saw to distribute the wear for maximum
bar life. The bar should be cleaned every day of
use and checked for wear and damage.
Feathering or burring of the bar rails is a normal process of bar wear. Such faults should be smoothed
with a file as soon as they occur.
A bar with any of the following faults should be
replaced.
 Wear inside the bar rails which permits the chain
to lay over sideways.

WARNING:
Although the guide bar comes with a SAFE-TTIP® anti-kickback nose guard already installed,
check the tightness of the mounting screw
before each use to avoid possible serious personal injury.
Use the following instructions to tighten the mounting screw of the nose guard. These are specially
hardened screws. If you cannot install the screw
tightly, replace both the screw and the SAFE-T-TIP®
before further operation.
Note: Do not replace the screw with an ordinary
screw. Use only identical replacement parts from
the manufacturer when replacing parts.
In addition to preventing chain contact with solid
objects at the nose of the bar, the SAFE-T-TIP® also
helps keep the chain away from abrasive surfaces,
such as the ground. Keep it on the right hand side
of the bar where it will be between the chain and
the ground during flush with ground cutting.
The mounting screw requires a 5/16 in. wrench (or
adjustable wrench) to achieve the recommended
torque of 35 to 45 in.lb. A torque within this range
can be achieved by using the following method.
