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
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 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. 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 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.
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 conditions. 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.
Always wear eye protection with side shields
marked to comply with ANSI Z87.1, along with head protection.

GENERAL SAFETY RULES
KICKBACK
See Figures 1 - 4.
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 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 kick-
®
back chain, SAFE-T-TIP 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.
With a basic understanding of kickback, you
can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

GENERAL SAFETY RULES
Keep proper footing and balance at all times. Do not cut above shoulder height or overreach
when cutting.
®
Keep the SAFE-T-TIP
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 4.

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 locations. 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 mate­rial may catch the saw chain and be whipped toward you or pull you off balance.
When cutting a limb that is under tension, be
alert for spring back so that you will not be struck when the tension in the wood fibers is released.
Do not force the chain saw. The job can be 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
®
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.
SPECIFIC SAFETY RULES
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.
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
Use only with charger listed. For use with 40V
lithium-ion battery packs, see tool/appliance/ battery pack/charger correlation supplement 988000-842.
Save these instructions. Refer to them fre-
quently and use them to instruct others who may use this tool. If you loan someone this tool, loan them these instructions also.

PREPARATION FOR CUTTING PROPER GRIP ON HANDLES
See Figures 9 -11.
Refer to GENERAL SAFETY RULES 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 danger­ous because a slight kick of the saw can cause loss of control.

WARNING:
Do not operate the switch trigger with your left hand and hold the front handle with your right hand. Never allow any part of your body to be in the chain line while operating a saw.
PROPER CUTTING STANCE
See Figures 12 - 13.
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.
Fig. 10
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.

OPERATION
WORK AREA PRECAUTIONS
See Figure 14.
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 pre-
vent being pulled off balance.
Do not cut above chest height, as a saw held high-
er 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.

Closely check for broken or dead branches, which could fall while cutting and do not cut near buildings or electrical wires if you do not know the direction of tree fall. Do not cut at night or during bad weather conditions, such as rain, snow, or strong winds, which can reduce visibility and control of the chain saw. If the tree you are felling makes contact with any utility line, you should discontinue use of the chain saw and immediately notify the utility company. Failure to follow these instructions could result in death or serious personal injury.
When felling a tree, it is important that you follow these warnings and instructions to prevent pos­sible serious injury.
■Do not cut down trees having an extreme lean or
large trees with rotten limbs, loose bark, or hol­low trunks. Have these trees pushed or dragged down with heavy equipment, then cut them up.

■Do not cut trees near electrical wires or buildings.
■Check the tree for damaged or dead branches
that could fall and hit you during felling.
■Periodically glance at the top of the tree during
the backcut to assure the tree is going to fall in the desired direction.
If the tree starts to fall in the wrong direction,
or if the saw gets caught or hung up during the fall, leave the saw and save yourself! Felling a tree - When bucking and felling opera-
tions are being performed by two or more 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
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.

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.
BUCKING
See Figures 18 - 21.
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.

Fig. 21
■ Cut only one log at a time.
■ Support small logs on a saw horse or another
log while bucking.
■ Keep a clear cutting area. Make sure that no objects can contact the guide bar nose and chain during cutting, this can cause kickback.
®
To avoid the danger, keep the SAFE-T-TIP
anti-
kickback nose guard attached while cutting. Refer to Precautions Against Kickback earlier in this manual.
OPERATION
3
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.
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.
SECOND CUT
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.
Fig. 22
Fig. 23
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.
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 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.
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:
SPRINGPOLE
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-

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.

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.

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
