manual before operating chain saw.

2. Use chain saw for cutting wood only. Do

not use for cutting any non-wood items.

3. Only well-instructed adults should op-

erate chain saw. Never allow children

to operate chain saw. First-time user

should obtain informed, practical in-

struction in addition to reading this

manual. Practice cutting logs on a saw

horse or cradle.

Read and understand all

Safety

Warnings

on pages 3 through 5.

Improper use of this chain saw can

cause severe injury or death from

ﬁre, electrical shock, body contact

with moving chain, or falling wood.

Kickback Safety Devices On

This Saw

This saw has a low-kickback chain and re-

duced-kickback guide bar. Both items reduce

the chance of kickback. Kickback can still

occur with this saw. Do not let tip of guide

bar touch anything when chain is moving.

Never hold the chain saw by the front hand

guard.

Cause Of Kickback

Kickback may occur when nose or tip of

guide bar touches an object while chain is

moving. If chain cutter catches on object, a

sudden reverse action will result. The guide

bar will kick up and back towards operator.

Kickback may also occur when wood

pinches chain at guide bar nose. A sudden

reverse action will also result.

WARNING: Avoid Kickback.

Kickback can cause you to lose

control of chain saw. Kickback

can cause severe injury or death.

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.

• 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).

•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 re-

place these parts with chains and guide

bars listed in this manual.

•Never use dull or loose chain. Keep chain

sharp and tensioned correctly.

•Never try cutting through two logs at

same time. Only cut one log at a time.

•Watch for shifting of log or other forces

that may pinch chain.

• Use extreme caution when reentering a

previous cut.

• Do not twist saw when removing guide

bar from undercut.

• Use wedges made of plastic, wood, or

light alloy (never steel or iron) to hold

cut open.

CHAIN SAW OPERATION

1. Stay alert. Use common sense while op-

erating chain saw.

2. Keep work area clean. Cluttered areas

invite injuries.

3. Be aware of extension cord while op-

erating chain saw. Be careful not to trip

over cord.

4. Keep children, animals, and bystand-

ers away from chain saw and extension

cord. Only chain saw user should be in

work area.

5. Do not cut down a tree unless you are

trained or have expert help.

6. If two or more persons perform buck-

ing and felling operations at the same

time, provide plenty of distance between

operations. Provide distance of at least

twice the height of tree being felled.

7. Secure wood you are cutting by using

clamps or chocks.

8. Grip chain saw ﬁrmly with both hands.

Never operate chain saw with one hand.

Never use hand guard as handle.

9. Keep ﬁnger off trigger until ready to

make cut.

10. Before starting chain saw, make sure

chain is not touching anything.

11. Avoid body contact with grounded ob-

jects such as pipes, wire fences, and

metal posts.

12. Keep all parts of body away from chain

when saw is running.

13. Do not force chain saw while cutting.

Apply light pressure.

14. Cut small brush and saplings with ex-

treme care. Slender material may catch

in chain and be whipped toward you.

This could also pull you off balance.

15. When cutting limb or tree trunk 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 caus-

ing severe injury or death.

16. Do not activate the chain brake to stop

saw. Always release trigger to stop saw.

17. Carry chain saw from one place to an-

other

• with chain saw unplugged

•by holding front handle (never use

front hand guard as handle)

• with ﬁnger off trigger

• with guide bar and chain to rear

• with scabbard in place

Saw Maintenance and Kickback

Safety

Follow maintenance instructions in this manual.

Proper cleaning of saw and chain and guide

bar maintenance can reduce chances of kick-

back. Inspect and maintain saw after each use.

This will increase the service life of your saw.

Note:

Even with proper sharpening, risk of

kickback can increase with each sharpening.

PUSHBACK AND PULL-IN

Cause Of Pushback and Pull-In

Pushback may occur while cutting with top

of guide bar. Pushback will force saw back

towards you. Pull-in may occur while cut-

ting with bottom of guide bar. Pull-in will

force saw in towards wood you are cutting.

These hazards can occur if chain is pinched,

caught, or contacts a non-wood object.

The following steps will reduce the risk of

pushback or pull-in:

• Use both hands to grip saw while saw is

running. Use ﬁrm grip. Thumbs and

ﬁngers must wrap around saw handles.

• Do not overreach or cut above shoulder

height.

•Keep solid footing and balance.

• Stand slightly to left side of saw. This

keeps your body from being in direct line

with chain.

•Have saw running at full speed before

starting a cut.

•When cutting, make sure spike of saw is

against wood (pull-in only). See Prod-

uct Identification, page 6, to locate spike.

WARNING: Avoid pushback

and pull-in. These hazards can

cause you to lose control of chain

saw. Pushback or pull-in can

cause severe injury.

WARNING: Some dust cre-

ated by power sanding, sawing,

grinding, drilling, and other con-

struction activities contains

chemicals known (to the state of

California) to cause cancer, birth

defects, or other reproductive

harm. Some examples of these

chemicals are:

• lead from lead-based paints

• crystalline silica from bricks

and cement and other masonry

products

• arsenic and chromium from

chemically-treated lumber

Your risk from these exposures

varies, depending on how often

you do this type of work. To re-

duce your exposure to these

chemicals: work in a well venti-

lated area, and work with ap-

proved safety equipment, such

as those dust masks that are spe-

cially designed to filter out mi-

croscopic particles.

WARNING: This product con-

tains chemicals known to the

State of California to cause can-

cer or birth defects, or other re-

productive harm.

EXTENSION CORDS

Use proper extension cord with this chain

saw. Use only extension cords marked for

outdoor use. Use an extension cord no less

than 1.5 mm

(14SWG) at distances up to

30 meters (100 feet). The cord must be

marked with suffix W following the cord

type marking.

Example:

SJTW

Use an extension cord heavy enough to carry

the current your saw will draw. An under-

sized cord will cause a voltage drop at the

saw, loss of power, and overheating.

Keep cord away from cutting area. Make

sure cord does not catch on branches or logs

during cutting. Inspect cords often. Replace

damaged cords.

The extension cord may come undone from the

power cord during use. To avoid this, make a

knot with the two cords as shown in Figure 7.

OILING CHAIN

Always check oil level before using saw. To

oil chain, press squeeze bulb on oil cap. Do

not attempt to operate the oiler while cut-

ting with the saw. Oil will feed onto guide

bar and chain. Press squeeze bulb on oil cap

at least once before each cut. Check oil level

often by looking at oil sight level hole. Oil

sight level hole is on left side of saw, be-

tween front handle and front hand guard.

CUTTING WITH THE CHAIN

SAW

1. Connect saw to extension cord. Con-

nect extension cord to power supply.

2. 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.

3. 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).

4. Make sure your footing is ﬁrm. Keep

feet apart. Divide your weight evenly

on both feet. Stand slightly to left side

of saw. This keeps your body from be-

ing in direct line with chain.

5. 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.

6. When starting a cut, place moving

chain against wood. Hold saw ﬁrmly

in place to avoid possible bouncing or

skating (sideways movement) of saw.

7. Guide saw using light pressure. Do not

force saw. The motor will overload and

can burn out.

8. Remove saw from a cut with saw run-

ning at full speed. Stop saw by releas-

ing trigger. Do not use the chain brake.

Make sure chain has stopped before

setting saw down.

9. Practice until you can maintain a steady,

even cutting rate.

FELLING A TREE (Cutting

Down a Tree)

WARNING:

• Avoid kickback. Kickback can

result in severe injury or death.

See

Kickback,

page 3, to avoid

risk of kickback.

• Do not fell a tree without ample

skill or expert help.

• Keep children, animals, and

bystanders away from area

when felling a tree.

• If two or more persons per-

form bucking and felling op-

erations at the same time, pro-

vide ample distance between

operations. Provide distance

of at least twice the height of

tree being felled.

WARNING: When felling a tree,

be aware of your surroundings. Do

not endanger any person, strike

utility lines, or cause property dam-

age. If tree strikes utility lines, con-

tact utility company at once.

Felling is the process of cutting down a tree.

Make sure your footing is ﬁrm. Keep feet

apart. Divide your weight evenly on both

feet. Follow directions below to fell a tree.

CAUTION: Seek professional

help if facing conditions beyond

your ability.

Before Felling a Tree

1. 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.

2. Clear work area around tree.

3. Plan and clear a retreat path before fell-

ing. Make retreat path opposite to

planned direction of fall of tree and at

45° angle (see Figure 11).

4. Remove dirt, stones, loose bark, nails,

staples, and wire from tree where you

will make felling cuts.

5. Stay on uphill side when felling tree. Tree

could roll or slide downhill after falling.

WARNING: Be alert for falling

overhead limbs. Watch your foot-

ing while exiting area.

3. As felling cut nears hinge, tree should

begin to fall.

Note:

If needed, drive

wedges into felling cut to control direc-

tion 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.

4. When tree begins to fall, quickly

BUCKING A LOG

Figure 14 - Bucking Log With Entire

Length On Ground

OPERATING CHAIN

SAW

Continued

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 un-

der tree that support log off ground. Remove

each limb with one cut (see Figure 13). 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.

CAUTION: Seek professional

help if facing conditions beyond

your ability.

WARNING: When cutting limb

that is under tension, use extreme

caution. Be alert for wood spring-

ing back. When wood tension is

released, limb could spring back

and strike operator causing se-

vere injury or death.

WARNING: Avoid kickback.

Kickback can result in severe in-

jury or death. See

Kickback,

page

3, to avoid risk of kickback.

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.

Stand slightly to left of saw. This keeps your

body from being in direct line with chain.

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 cut-

ting through log, release trigger to turn saw

off before moving saw.

Follow directions below to buck a log.

Entire Length Of Log On

Ground

Cut log from top (see Figure 14).

CAUTION: Seek professional

help if facing conditions beyond

your ability.

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 be-

fore moving from one place to

another.

WARNING: Avoid kickback.

Kickback can result in severe in-

jury or death. See

Guide Bar

Figure 17 - Guide Bar Cross Section

Showing Uneven Bar Wear

Keep saw body clean. Use a soft cloth damp-

ened with a mild soap and water mixture.

Wipe saw body to clean.

CARE OF GUIDE BAR

Uneven bar wear causes most guide bar prob-

lems. 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.

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.

WARNING: When cleaning

saw body

• do not submerge saw in any

liquids

• do not use products that con-

tain ammonia, chlorine, or

abrasives

• do not use chlorinated clean-

ing solvents, carbon tetrachlo-

ride, kerosene, or gasoline

WARNING: Cutting edges on

chain are sharp. Use protective

gloves when handling chain.

WARNING: Unplug chain saw

from power source before servic-

ing. Severe injury or death could

occur from electrical shock or

body contact with moving chain.

CLEANING SAW BODY

NOTICE: Below are instructions

for servicing your chain saw. Any

servicing not mentioned below

should be done by an authorized

Normal Guide Bar Maintenance

1. Remove guide bar from chain saw.

2. Remove sawdust from guide bar groove

periodically. Use putty knife or wire.

3. Clean oil slots after each day of use.

4. Remove burrs from sides of guide bar.

Use ﬂat ﬁle to make side edges square.

Replace guide bar when

• bar is bent or cracked

• inside groove of bar is badly worn

Note:

When replacing guide bar, see Re-

placement Parts, page 14, for proper bar.

CLEANING AND

MAINTENANCE

Continued

Keep chain sharp. Your saw will cut faster

and more safely. A dull chain will cause

undue sprocket, guide bar, chain, and mo-

tor wear. If you must force chain into wood

and cutting creates only sawdust with few

large chips, chain is dull.

Items Needed to Sharpen Chain

Purchase these items from your local dealer,

hardware store, or chain saw supplies outlet.

•4 mm (5/32") round ﬁle

• File guide

• Medium sized ﬂat ﬁle

•Depth gauge tool

•Vise

Sharpening Cutters

Use ﬁle guide for 30° ﬁling.

1. Adjust chain for proper tension (see Saw

Chain Tension Adjustment, page 8).

2. Clamp guide bar in vise to hold saw

steady.

Note:

Do not clamp chain.

3. Press four millimeter (5/32") round ﬁle

(attached to ﬁle guide) into groove be-

tween 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.

4. 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.

5. File from inside towards outside of cut-

ter until sharp. Only ﬁle in this one direc-

tion (see Figure 19).

Note:

Two or three

strokes with ﬁle should sharpen cutter.

6. After each cutter if sharpened, move

chain forward to sharpen next cutter.

File all cutters on one side of chain.

7. Move to other side of chain and repeat

process.

WARNING: Cutting edges on

chain are sharp. Use protective

gloves when handling chain.

WARNING: Unplug chain saw

from power source before servic-

ing. Severe injury or death could

occur from electrical shock or

body contact with moving chain.

STORAGE

If storing saw for more than 30 days, fol-

low steps below.

1. Drain oil tank.

2. Remove and clean guide bar and chain.

Clean guide bar and chain by soaking

in petroleum based solvent or mild soap

and water mixture.

3. Dry guide bar and chain.

4. Place chain in container ﬁlled with oil.

This will prevent rust.

5. Wipe a thin coating of oil over surface

of guide bar.

6. Wipe off outside of saw body. Do this

with soft cloth dampened with a mild

soap and water mixture.

7. Store chain saw

• in a high or locked place, out of

children’s reach

• in a dry place

• in a carrying case or with scabbard

over guide bar

• with oil cap tight and saw upside

down to prevent excess oil seepage

After several hand ﬁlings, have authorized

service center or sharpening service machine

sharpen chain. This will insure even ﬁling.

Replacing Saw Chain

Replace chain when cutters are too worn to

sharpen or when chain breaks. Only use re-

placement chain noted in this manual. Al-

ways include new drive sprocket when re-

placing chain. This will maintain proper

driving of chain.

Note:

For proper chain and

drive sprocket, see Replacement Parts.

Purchase these parts from your local dealer.
