MAINTENANCE AND
STORAGE OF CHAIN SAW
SAFETY
WARNINGS
1.
KICKBACK
WARNING: Kickback may occur when the nose or tip of the
guide bar touches an object, or
when the wood closes in and
pinches the saw chain in the cut.
Tip contact in some cases may
cause a lightning fast reverse reaction, kicking the guide bar up
and back towards the operator.
Pinching the saw chain along the
top of the guide bar may push the
guide bar rapidly back towards
the operator. Either of these reactions may cause you to lose
control of the saw which could
result in serious injury to user.
Kickback Safety Devices On
This Saw
This saw has a low-kickback chain and
reduced kickback guide bar. Both items
reduce the chance of kickback. Kickback
can still occur with this saw.
Properly install front hand guard. This item
can reduce injuries from kickback. Follow
assembly instructions on page 6. Do not
remove front hand guard. Do not replace
front hand guard with substitute.
The following steps will reduce the risk of
kickback.
• Use both hands to grip saw while saw is
running. Use firm grip. Thumbs and
fingers must wrap around saw handles.
• Keep all safety items in place on saw.
Make sure they work properly.
• Do not overreach or cut above shoulder
height.
• Keep solid footing and balance at all
times
• Stand slightly to left side of saw. This
keeps your body from being in direct line
with chain.
• Do not let guide bar nose touch anything
when chain is moving (see Figure 1).

While Chain is Moving
• Never try cutting through two logs at
same time. Only cut one log at a time.
• Do not bury guide bar nose or try plunge
cut (boring into wood using guide bar
nose).
• Watch for shifting of wood or other
forces that may pinch chain.
• Use extreme caution when reentering a
previous cut.
• Use low-kickback chain and guide bar
supplied with this chain saw. Only replace these parts with chains and guide
bars listed in this manual.
• Never use dull or loose chain. Keep chain
sharp with proper tension.
• Do not hand sharpen chain on automatic
chain sharpening (Fast Sharp) models.
Saw Maintenance and Kickback
Safety
Follow maintenance instructions in this
manual. Proper cleaning of saw and chain
and guide bar maintenance can reduce

CUTTING WITH THE CHAIN
SAW
9.
Connect saw to extension cord. Connect extension cord to power supply.
Make sure section of log to be cut is
not laying on ground. This will keep
chain from touching ground as it cuts
through log. Touching ground with
moving chain will dull chain.
Use both hands to grip saw. Always use
left hand to grip front handle and right
hand to grip rear handle. Use firm grip.
Thumbs and fingers must wrap around
saw handles (see Figure 9).
Make sure your footing is firm. Keep
feet apart. Divide your weight evenly
on both feet.
When ready to make a cut, press in
switch lockout with right thumb and
squeeze trigger (see Figure 9). This will
turn saw on. Releasing trigger will turn
saw off. Make sure saw is running at
full speed before starting a cut.
When starting a cut, place moving
chain against wood. Hold saw firmly
in place to avoid possible bouncing or
skating (sideways movement) of saw.
Guide saw using light pressure. Do not
force saw. The motor will overload and
can burn out. It will do the job better
and safer at the rate for which it was
intended.
Remove saw from a cut with saw running at full speed. Stop saw by releasing trigger. Make sure chain has
stopped before setting saw down.
Practice until you can maintain a steady,
even cutting rate.

Before felling, inspect tree. Make sure
there are no dead limbs or branches that
may fall on you. Study natural lean of
tree, location of larger branches, and
wind direction. This will help you judge
which way tree will fall.
Clear work area around tree.
Plan and clear a retreat path before felling. Make retreat path opposite to
planned direction of fall of tree and at
45° angle (see Figure 10).
Remove dirt, stones, loose bark, nails,
staples, and wire from tree where you
will make felling cuts.
Stay on uphill side when felling tree.

Figure 10 - Retreat Path From Tree
Felling Procedure
A) Felling Notch
A properly placed felling notch will determine direction tree will fall. Place felling
notch on side of tree in direction you want
tree to fall (see Figure 11). Follow directions below to create a felling notch.
1. Make lower notch cut as close to
ground as possible. Hold saw so guide
bar is horizontal. Cut 1/3 the diameter
of tree trunk (see Figure 11). Note: Always make this horizontal lower notch
cut first. If you make this cut second,
tree can pinch chain or guide bar.
2. Start upper notch cut the same distance
above first cut as first cut is deep.
Example: If lower notch cut is eight
inches deep, start upper notch cut eight
inches above it. Cut downward at 45°
angle. The upper notch cut should meet
end of lower notch cut (see Figure 11).
3. Remove tree trunk wedge created by
notching cuts.
Figure 11 - Felling A Tree
3.
4.
As felling cut nears hinge, tree should
begin to fall. Note: If needed, drive
wedges into felling cut to control direction of fall. If tree settles back and pinches
chain, drive wedges into felling cut to
remove saw. Only use wedges made of
wood, plastic, or aluminum. Never use
wedge made of steel. This could cause
kickback and damage to chain.
When tree begins to fall, quickly
• remove saw from felling cut
• release trigger to turn saw off
• put saw down
• exit area using retreat path
WARNING: Be alert for falling
overhead limbs. Watch your footing while exiting area.
B) Felling Cut
1.
2.
Make felling cut two inches higher than
lower notch cut and on opposite side
of tree (see Figure 11). Keep felling cut
parallel to lower notch cut.
Cut towards notch.
WARNING: Do not cut all the
way through tree. Leave about
two inches of tree diameter uncut directly behind felling notch
(see Figure 11). This uncut portion acts as a hinge. The hinge
helps keep tree from twisting and
falling in wrong direction.

LIMBING A TREE
WARNING: Avoid kickback.
Kickback can result in severe injury or death. See Kickback, page
3 to avoid risk of kickback.
WARNING: When cutting limb
that is under tension, use extreme
caution. Be alert for wood springing back. When wood tension is
released, limb could spring back
and strike operator causing severe injury or death.
Limbing is removing branches from a fallen
tree. Make sure your footing is firm. Keep
feet apart. Divide your weight evenly on
both feet. Do not remove larger limbs under
tree that support log off ground. Remove
each limb with one cut (see Figure 12).
Clear cut limbs from work area often. This
will help maintain a safe work area.
Make sure you start your cut where limb
will not pinch saw during cutting. To avoid
pinching, start cut on freely hanging limbs
from above limb. Start cut on limbs under
tension from under limb. If pinch occurs,
turn saw off, lift limb, and remove saw.
BUCKING A LOG
WARNING: Avoid kickback.
Kickback can result in severe injury or death. See Kickback, page
3 to avoid risk of kickback.
WARNING:
• If on slope, make sure log will
not roll down hill. Secure log
by using wooden stakes. Drive
wooden stakes into ground on
downhill side of log. Stand on
uphill side of log while cutting.
Log may roll after cutting.
• Never try cutting through two
logs at same time. This could
increase the risk of kickback.
• While cutting log, never hold
log with your hand, leg, or foot.
• While cutting log, never allow
another person to hold log.
• Turn off and unplug saw before moving from one place to
another.
Bucking a log is cutting a log into sections.
Make sure your footing is firm. Keep feet
apart. Divide your weight evenly on both feet.
When possible, raise log or section off ground.
Do this by using limbs, logs, chocks, etc.
When cutting through log, maintain control
by reducing cutting pressure near end of cut.
Do not relax your grip on chain saw handles.
Do not let moving chain touch ground.
Ground will dull moving chain. After cutting through log, release trigger to turn saw
off before moving saw.

ELECTRIC CHAIN SAW
CLEANING AND
MAINTENANCE
NOTICE: Below are instructions
for servicing your chain saw. Any
servicing not mentioned below
should be done by an authorized
service center.
CLEANING SAW BODY
CARE OF GUIDE BAR
Normal Guide Bar Maintenance
Uneven bar wear causes most guide bar
problems. Incorrect sharpening of chain
cutter and depth gauge settings often cause
this. When bar wears unevenly, it widens
guide bar groove (see Figure 17). This causes
chain clatter and rivet popping. Saw will not
cut straight. Replace guide bar if this occurs.
1.
2.
Inspect guide bar before sharpening chain.
A worn or damaged guide bar is unsafe. A
worn or damaged guide bar will damage
chain. It will also make cutting harder.
Replace guide bar when
• bar is bent or cracked
• inside groove of bar is badly worn
WARNING: Unplug chain saw
from power source before servicing. Severe injury or death could
occur from electrical shock or
body contact with moving chain.
3.
4.
Remove guide bar from chain saw.
Remove sawdust from guide bar
groove periodically. Use putty knife or
wire.
Clean oil slots after each day of use.
Remove burrs from sides of guide bar.
Use flat file to make side edges square.
Note: When replacing guide bar, see Replacement Parts and Accessories, page 19,
for proper bar.

WARNING: When cleaning
saw body,
• do not submerge saw in any
liquids
• do not use products that contain ammonia, chlorine, or
abrasives
• do not use chlorinated cleaning solvents, carbon tetrachloride, kerosene, or gasoline
Keep saw body clean. Use a soft cloth dampened with a mild soap and water mixture.
Wipe saw body to clean.

SHARPENING SAW CHAIN
WARNING: Unplug chain saw
from power source before servicing. Severe injury or death could
occur from electrical shock or
body contact with moving chain.
WARNING: Cutting edges on
chain are sharp. Use protective
gloves when handling chain.
Use file guide for 30° filing.
1. Adjust chain for proper tension (see Saw
Chain Tension Adjustment, page 7).
2. Clamp guide bar in vise to hold saw
steady. Note: Do not clamp chain.
3. Press 5/32" round file (attached to file
guide) into groove between top plate
and depth gauge on chain. File guide
should rest on both top plate and depth
gauge (see Figures 19 and 20). Note:
File at midpoint of guide bar.
5.
6.
7.
Hold file guide level. Make sure 30°
mark on file guide is parallel to center
of guide bar (see Figure 19). This will
insure that you file cutters at 30° angle.
File from inside towards outside of cutter until sharp. Only file in this one direction (see Figure 19). Note: Two or three
strokes with file should sharpen cutter.
After each cutter is sharpened, move
chain forward to sharpen next cutter.
File all cutters on one side of chain.
Move to other side of chain and repeat
process.

HOLDER
Keep chain sharp. Your saw will cut faster
and more safely. A dull chain will cause
undue sprocket, guide bar, chain, and motor
wear. If you must force chain into wood and
cutting creates only sawdust with few large
chips, chain is dull.
