IMPORTANT SAFETY INSTRUCTIONS
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. 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 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.
■ Do not cut vines and/or small underbrush.
SAFETY APPAREL
■ Wear snug fitting clothing. Always wear heavy, long
pants, overalls, jeans or chaps made of cut resistant material or ones that contain cut resistant
inserts. Wear non-slip safety footwear. Wear nonslip heavy duty gloves to improve your grip and to
protect your hands. Do not wear jewelry, short
pants, sandals, or go barefoot. Do not wear loose
fitting clothing, which could be drawn into the motor
or catch the chain or underbrush. Secure hair so it
is above shoulder level.
■ Wear 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
KICKBACK
See Figures 1 and 2.
■ 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.
■ 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.
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.
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. 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 instructions for the saw chain.

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.
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.
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.
■ 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 performed better and safer at the rate for which it was
intended.
■ Always use the right product for your application.
The chain saw should be used for cutting wood
only. Never use the chain saw to cut plastic,
masonry or non-wood building materials.
■ 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.

IMPORTANT SAFETY INSTRUCTIONS
UNDERSTANDING YOUR CHAIN SAW
SAFETY DEVICES
See Figure 4.
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.
SAFE-T-TIP
Fig. 4
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 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.
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 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®.
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.
BATTERY PACK: Item # 1322401,
1323303, 130224007,
or 130256001
CHARGER: Item # 1423701
■ 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.
■ 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.
■ 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 (10°C) but less than 100°F (38°C).
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.

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 protection.
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 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.

OPERATION
PROPER CUTTING STANCE
See Figure 13.
■ 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 your saw before
you begin a major sawing operation.
1. Take the proper stance in front of the wood with the
saw off.
2. Squeeze the trigger and let the chain accelerate to
full speed before entering the cut.
3. Begin cutting with the saw against the log.
4. Keep the unit running the entire time you are
cutting, maintain a steady speed.
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.
6. Release the 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.
7. Do not put pressure on the saw at the end of the
cut.

■ 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.
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.
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 your 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
(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 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.
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.
17
OPERATION
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.
■ 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.

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.
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.
■ 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.
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.
See Figure 17.
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.
See
WEDGE
Fig. 17
BUCKING
See Figures 18 through 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.
■ 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 device
attached while cutting. Refer to “Precautions Against
Kickback” earlier in this manual.

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 your 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.
See Figure 19.
BUCKING LOGS UNDER STRESS
See Figures 20 and 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 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.

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.
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.
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.
OVERBUCKING
UNDERBUCKING
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.
■ 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 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.
1. Underbuck the branch 1/3 through for your first
cut.
2. Your second cut should overbuck to drop the
branch off.
3. 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,

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.
Fig. 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.

MAINTENANCE
CUTTING
CORNER
CAUTION:
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 fastcutting chain will provide kickback reduction when
properly maintained.
For smooth and fast cutting, chain needs to be maintained 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:
■ 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.

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.
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.
Fig. 34

MAINTENANCE
5. 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.
WARNING:
Failure to replace or repair damaged chain can
cause serious injury.
WARNING:
The saw chain is very sharp, always wear
protective gloves when performing maintenance
to the chain.

(0.6 mm) 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
See Figure 41
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.
■ 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.
Turn the guide bar and check that the lubrication holes
and chain groove are free from impurities.

MAINTENANCE
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-TTIP® anti-kickback device already installed, you
need to check the tightness of the mounting
screw before each use.
SAFE-T-TIP® NOSE GUARD MAINTENANCE
See Figures 42 and 43.
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.
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.
1. Tighten the screw with your finger.
2. From the finger-tight position, tighten the screw an
additional 3/4 of a turn using a wrench.
MOUNTING SAFE-T-TIP® NOSE GUARD

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.
■ 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.
■ 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.
BATTERIES
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.
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 disassemble battery pack and attempt to replace the
batteries. Handling of these batteries, especially when
wearing rings and jewelry, could result in a serious
burn.
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 discharged.
■ 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.
DISPOSAL OF THE EXHAUSTED BATTERY
To preserve natural resources,
please recycle or dispose of properly. This product contains a nickelcadmium battery. Must be disposed
of properly. Local, state, or federal
laws may prohibit disposal of NickelCadmium batteries in ordinary trash.
Consult your local waste authority for
information regarding available recy-
