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.  
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.  
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.  
All chain saw service, other than the items listed in  
the operation and maintenance sections, should be  
performed by your nearest Ryobi service dealer.  
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.  
Do not use in the rain, snow or wet conditions.  
Always maintain a proper stance.  
Do not adapt your powerhead to a bow guide or  
use it to power any attachments or devices not  
listed for your saw.  
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.  
Do not cut vines and/or small underbrush.  
SAFETY APPAREL  
Before you start the unit, make sure the saw chain  
is not contacting any object.  
Wear snug fitting clothing. Always wear heavy, long  
pants, overalls, jeans or chaps made of cut resis-  
tant 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.  
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.  
Wear eye protection which is marked to comply  
with ANSI Z87.1 as well as hearing and head  
protection when operating this equipment.

IMPORTANT SAFETY INSTRUCTIONS  
Do not cut above shoulder height or overreach  
when cutting.  
KICKBACK  
See Figures 1 and 2.  
Keep the SAFE-T-TIP anti-kickback nose guard  
properly mounted on the guide bar to prevent  
rotational kickback.  
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 your  
saw. As a chain saw user, you should take several  
steps to keep your cutting jobs free from accident  
or injury.  
Follow the sharpening and maintenance instruc-  
tions for the saw chain.  
ROTATIONAL  
KICKBACK  
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 the 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.

KICKBACK  
DANGER ZONE  
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 throttle trigger and maintain a  
steady cutting speed.  
Fig. 2  
4. Use replacement parts such as low kickback  
chain, SAFE-T-TIP anti-kickback nose guards,  
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 your saw.  
With a basic understanding of kickback, you can  
reduce or eliminate the element of surprise. Sud-  
den surprise contributes to accidents.  
Keep proper footing and balance at all times.

IMPORTANT SAFETY INSTRUCTIONS  
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,  
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.  
PULL  
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 locations.  
Do not use the chain saw near flammable liquids,  
gases, or in any type of explosive atmosphere.  
Use 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.  
PUSH  
Fig. 3  
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 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.  
Do not use the chain saw for purposes not in-  
tended.  
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.

IMPORTANT SAFETY INSTRUCTIONS  
UNDERSTANDING YOUR CHAIN SAW  
SAFETY DEVICES  
See Figure 4.  
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 haz-  
ards even when unit is not operating.  
SAFE-T-TIP® Anti-Kickback Nose Guard  
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.  
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.

Fig. 4  
To reduce the risk of explosion and possible injury,  
Do not place battery units or their batteries near fire  
or heat.  
LOW KICKBACK SAW CHAIN  
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.  
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.  
A damaged battery pack is subject to explosion. To  
avoid serious personal injury, properly dispose of a  
damaged battery pack.  
Batteries vent hydrogen gas and 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.  
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 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.  
Do not charge unit in a damp or wet location.  
Following this rule will reduce the risk of electric  
shock.  
GUIDE BARS  
For best results, your battery unit should be  
charged in a location where the temperature is  
more than 50°F (10°C) but less than 100°F (38°C).  
Do not store outside or in vehicles.  
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 your 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®.  
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.

When using your chain saw continuously, the batteries  
in your battery pack will become hot. You should let a  
hot battery pack cool down for approximately 30  
minutes before attempting to recharge.  
NOTE: This situation only occurs when continuous use  
of your chain saw causes the batteries to become hot.  
It does not occur under normal circumstances. Refer  
to “Charging Your Chain saw” earlier in this manual, for  
normal recharging of batteries. If the charger/charging  
assembly does not charge your battery pack under  
normal circumstances, return both the battery pack  
and charger/charging assembly to your nearest Ryobi  
Authorized Service dealer for electrical check.  
When your battery pack becomes fully charged,  
the red light will turn off and the green light will turn  
on.  
After normal usage, 1 hour of charge time is  
required to be fully charged. A minimum charge  
time of 1 to 1-1/2 hours is required to recharge a  
completely discharged tool.

pack snap in place and that battery pack is secured  
in chain saw before beginning operation.  
CHAIN OIL SYSTEM  
See Figure 8.  
TO REMOVE BATTERY PACK  
See Figure 7.  
1. Use Homelite Bar and Chain Oil. It is formulated to  
perform over a wide temperature range with no  
dilution required.  
Locate latches on side of battery pack and depress  
both sides to release the battery pack from the chain  
saw.  
NOTE: Do not use dirty, used or otherwise contami-  
nated oils. Damage may occur to the bar or chain.  
CAUTION:  
2. Carefully pour the bar and chain oil into the tank.  
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.  
3. Check and fill the oil tank when battery is re-  
charged, or as needed.  
4. Depress the oil tank cap several times to pump the  
oil to the chain before starting the saw.  
5. 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  
Figures 10, 11, and 12.  
Refer to “Important Safety Instructions” earlier in this  
manual for appropriate safety equipment.  
1. Wear non-slip gloves for maximum grip and protec-  
tion.  
2. 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.

OPERATION  
WARNING:  
Never use a left-handed (cross-handed) grip, or  
any stance which would place your body or arm  
across the chain line.  
3. 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 handle-  
bar. 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.  
CHAIN LINE

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.

See Figure 13.  
Weight should be balanced with both feet on solid  
ground.  
CHAIN LINE  
STRAIGHT ARM  
POSITION  
Keep left arm with elbow locked in a "straight arm"

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 your saw before  
you begin a major sawing operation.  
Fig. 13  
1. Take the proper stance in front of the wood with the  
saw off.  
Always cut with both feet on solid ground to prevent  
being pulled off balance.  
2. Squeeze the trigger and let the chain accelerate to  
full speed before entering the cut.  
Do not cut above chest height, as a saw held  
higher is difficult to control against kickback forces.  
3. Begin cutting with the saw against the log.  
4. Keep the unit running the entire time you are  
cutting, maintain a steady speed.  
Do not fell trees near electrical wires or buildings.  
Leave this operation for professionals.  
5. 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.  
Cut only when visibility and light are adequate for  
you to see clearly.  
6. 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.  
TREE FELLING  
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.  
7. 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.  
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.  
Never allow children to operate your saw. Allow no  
person to use this chain saw who has not read this  
Operator's Manual or received adequate instruc-  
tions 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  
(4.5 m) 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.  
WARNING:  
Do not cut trees near electrical wires or  
buildings.  
WARNING:  
Check the tree for damaged or dead branches  
that could fall and hit you during felling.

OPERATION  
PLANNED LINE OF FALL  
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!  
90°  
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 sepa-  
rated 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 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.  
SAFE  
RETREAT  
ZONE  
Fig. 14  
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.  
HINGE  
2 IN. (5 CM) OR 1/10 DIA  
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.

OPERATION  
Felling Backcut. The backcut is always made  
level and horizontal, and at a minimum of 2 inches  
(5 cm) above the horizontal cut of the notch. See  
Figures 15 and 16.  
Never cut through to the notch. Always leave a  
band of wood between the notch and backcut  
(approximately 2 inches (5 cm) 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 and 16.  
Fig. 17  
WEDGE  
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.  
BUCKING  
See Figures 18 through 21.  
Bucking is the term used for cutting a fallen tree to the  
desired log length.  
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.  
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.  
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.  
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 dan-  
ger, keep the SAFE-T-TIP® anti-kickback device  
attachedwhilecutting. RefertoPrecautionsAgainst  
Kickback” earlier in this manual.  
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.

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  
letthechaincontacttheground. Aftercompletingthe  
cut, wait for the saw chain to stop before your move  
the chain saw. Always stop the motor before moving  
from tree to tree. See Figure 19.  
When the log is supported along its entire length, it  
should be cut from the top or overbucking.  
When the log is supported on one end, cut 1/3 the  
diameter from the underside or 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.  
Sometimes it is impossible to avoid pinching (with  
juststandardcuttingtechniques)ordifficulttopredict  
which way a log will settle when cut. To avoid  
pinching while cutting, rotate or move the log so that  
the pinch is eliminated.  
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 19. 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 your move the chain saw. Always stop the  
motor before moving from tree to tree. See Figure 19.

TYPES OF CUTTING USED  
See Figure 21.  
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.  
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  
LIMBING  
See Figure 22.  
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.  
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.  
OVERBUCKING  
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 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 danger-  
ous. Leave this operation for professionals.  
FIRST CUT  
1/3 DIAMETER  
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.  
FINISHING CUT  
Fig. 23  
1. Underbuck the branch 1/3 through for your first  
cut.  
2. Your second cut should overbuck to drop the  
branch off.  
SPRINGPOLE  
3. 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  
If the limbs to be pruned are above chest height,  
hire a professional to perform the pruning.  
SPRINGPOLES  
See Figure 24.  
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.  
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.

properly maintained.  
GULLET  
Fig. 32  
For smooth and fast cutting, chain needs to be main-  
tained properly. The chain requires sharpening 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:  
CHECK FOR WEAR OR  
DAMAGE  
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.  
Fig. 33  
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.  
HOW TO SHARPEN THE CUTTERS  
See Figure 34 and 35.  
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.  
1. 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.  
Fig. 34  
2. Use A 5/32 in. diameter round file and holder.  
3. Keep the file level with the top plate of the tooth. Do  
not let the file dip or rock.  
4. Using light but firm pressure, stroke towards the  
front corner of the tooth.  
Lift file away from the steel on each return stroke.

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.

SHAPE BY ROUNDING  
THE FRONT  
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 re-  
placed.  
Fig. 40  
Wear inside the bar rails which permits the chain to  
lay over sideways.  
Bent guide bar.  
Cracked or broken rails.  
Spread rails.  
In addition, guide bars with a sprocket at their tip must  
be lubricated weekly with a grease syringe to extend  
the guide bar life. Using a grease syringe, lubricate  
weekly in the lubricating hole. See Figure x.  
LUBRICATING HOLE  
Turn the guide bar and check that the lubrication holes  
and chain groove are free from impurities.

MAINTENANCE  
MOUNTING SCREW  
LOCKING RIVET  
CAUTION:  
Remove the battery pack and make sure the  
chain has stopped before you do any work on  
the saw.  
WARNING:  
Although the guide bar comes with a SAFE-T-  
TIP® anti-kickback device already installed, you  
need to check the tightness of the mounting  
screw before each use.  
SAFE-T-TIP  
SAFE-T-TIP® NOSE GUARD MAINTE-  
NANCE  
See Figures 42 and 43.  
Fig. 42  
Tighten the mounting screw of the nose guard as  
instructed below. These are specially hardened  
screws. If the screw cannot be installed tightly, replace  
both the screw and the SAFE-T-TIP® before further  
operation. Do not replace with an ordinary screw.  
TIGHTEN 3/4  
OF A TURN  
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  
tightness of 35 to 45 in. lb. (4-5 Nm). A tightness  
within this range can be achieved by the following  
method.

MAINTENANCE  
BATTERIES  
WARNING:  
The battery pack for your chain saw is equipped with  
nickel-cadmium rechargeable batteries. Length of  
service from each charging will depend on the type of  
work you are doing.  
Do not attempt to modify this tool or create  
accessories not recommended for use with this  
tool. Any such alteration or modification is  
misuse and could result in a hazardous condition  
leading to possible serious personal injury.  
The batteries in this tool have been designed to  
provide maximum trouble free life. However, like all  
batteries, they will eventually wear out. Do not disas-  
semble battery pack and attempt to replace the  
batteries. Handling of these batteries, especially when  
wearing rings and jewelry, could result in a serious  
burn.  
WARNING:  
Any repairs requiring disassembly should only be  
performed by a Ryobi Authorized Service dealer.  
For the repair center nearest you, call 1-800-  
525-2579.  
To obtain the longest possible battery life, we suggest  
the following:  
Store and charge your batteries in a location where  
the temperature is above 50°F but less than 100°F.  
Never store batteries in a discharged condition.  
Recharge them immediately after they are dis-  
charged.  
TRANSPORTING AND STORING  
See Figure 44.  
Do not store or transport the chain saw when it is  
running. The chain saw should always be idle  
before storing or transporting.  
All batteries gradually lose their charge. The higher  
the temperature the quicker they lose their charge.  
If you store your chain saw for long periods of time  
without using it, recharge it every month or two.  
This practice will prolong battery life.  
Always place the guide bar scabbard on the bar  
and chain before storing or transporting the chain  
saw. Use caution to avoid the sharp teeth of the  
chain.  
DISPOSAL OF THE EXHAUSTED BATTERY  
To preserve natural resources,  
please recycle or dispose of prop-  
erly. This product contains a nickel-  
cadmium battery. Must be disposed  
of properly. Local, state, or federal  
laws may prohibit disposal of Nickel-  
Cadmium batteries in ordinary trash.  
Clean the chain saw thoroughly before storing.  
Store the chain saw indoors, in a dry place that is  
locked and/or inaccessible to children.  
Keep away from corrosive agents such as garden  
chemicals and de-icing salts.  
Consult your local waste authority for  
information regarding available recy-  
cling and/or disposal options. For more information on  
battery recycling call 1-800-8BATTERY.  
BATTERY PACK PREPARATION FOR RECYCLING
