IMPORTANT SAFETY
INFORMATION

WARNING: When using an electric
chain saw, basic safety precautions
should always be followed to reduce the
risk of fire, electric shock, and injury to
persons, including the following:

READ ALL INSTRUCTIONS.

Make sure you read and understand all in
structions in Important Safety Information
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.

BEFORE OPERATING SAW

1. Read and understand this owner’s manual before
operating chain saw.

2. Watch what you are doing. Use common sense.
Do not operate saw when you are tired.

3. Use chain saw for cutting wood only. Do not use
chain saw for purpose not intended. Do not use
for cutting plastic, masonry, etc.

4. Only well-instructed adults should operate chain
saw. Never allow children to operate chain saw.

5. Use only electrical voltage noted on model plate
of chain saw.

6. Use only extension cords marked for outdoor use.
See page 10 for extension cord requirements.

7. Do not operate chain saw

• while under the influence of alcohol, medica

tion, or drugs

• in rain or in damp or wet areas

• where highly flammable liquids or gases are

present

• if saw is damaged, adjusted wrong, or not fully

and securely assembled

• if trigger does not turn saw on and off. Chain

must stop moving when you release trigger.
Have faulty switch replaced by authorized ser
vice center (see Technical Service, page 16).

• while in a hurry

• while in tree or on a ladder unless trained to

do so

8. Wear snug-fitting clothes when operating chain
saw. Do not wear loose clothing or jewelry. They
can get caught in moving saw chain.

9. Wear the following safety gear when operating
chain saw.

• heavy-duty gloves (wear rubber gloves when

working outdoors)

• steel-toed safety footwear with non-skid soles

• eye protection such as safety glasses, goggles,

or face screen

107705

-

• safety hard hat

• ear mufflers or ear plugs

• hair covering to contain long hair

• face or dust mask (if working in dusty areas)

10. Before cutting, always provide the following:

• clear work area

• secure footing

• planned retreat path from falling tree

11. Inspect tree before cutting down. Make sure there are
no dead limbs or branches that may fall on you.

12. To reduce the risk of electric shock, this saw has a
polarized plug (one blade is wider than the other).
This plug will fit in a polarized outlet only one
way. If the plug does not fit fully in the outlet of
your extension cord, reverse the plug. If it still
does not fit, a polarized extension cord will be
necessary. Do not change the plug in any way.

WHILE OPERATING SAW

1. Stay alert. Use common sense while operating
chain saw.

2. Keep work area clean. Cluttered areas invite
injuries.

3. Be aware of extension cord while operating chain
saw. Be careful not to trip over cord. Keep cord
away from chain and operator at all times.

4. Keep children, animals, and bystanders 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 bucking and fell
ing 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. To guard against electrical shock, avoid body
contact with grounded objects such as pipes,
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. It will do the job better and safer at the
rate for which it was intended.

14. Cut small brush and saplings with extreme care.
Slender material may catch in chain and be
whipped toward you. This could also pull you
off balance.

IMPORTANT SAFETY
INFORMATION

Continued

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. Carry chain saw from one place to another

• with saw stopped and unplugged

• by holding front handle (never use hand guard

as handle)

• with finger off trigger

• with guide bar and chain to rear

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 opera
tor. 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.

-

WARNING: This product contains
chemicals known to the State of Cali
fornia to cause cancer or birth defects,
or other reproductive harm.

WARNING: Some dust created by
power sanding, sawing, grinding, drill
ing, and other construction activities
contains chemicals known (to the state
of California) to cause cancer, birth de
fects, or other reproductive harm. Some
examples of these chemicals are:

• lead from lead-based paints

• crystalline silica from bricks and ce

ment 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 reduce your exposure to
these chemicals: work in a well ventilated
area, and work with approved safety
equipment, such as those dust masks
that are specially designed to filter out
microscopic particles.

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.
Follow assembly instructions on pages 7 and 8. 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).

EXTENSION CORDS

Use proper extension cords with this saw. Use only
extension cords marked for outdoor use. The cord must
be marked with suffix W or W-A following the cord
type designation. Example: SJTW-A or SJTW.
Use proper sized cord with this saw. Cord must be heavy
enough to carry current needed. An undersized cord will
cause voltage drop at saw. Saw will lose power and over
heat. Follow cord size requirements listed below.

Cord Length AWG Cord Size
25 feet 16 AWG

50 feet 16 AWG
100 feet 14 AWG
150 feet 12 AWG

Models EL-8: 107624-01, -02; 107625-01, -02,
111174-01

Keep cord away from cutting area. Make sure cord
does not catch on branches or logs during cutting.
Inspect cords often. Replace damaged cords.
This chain saw is designed with an extension cord hitch
that prevents the extension cord from being pulled loose
during use. To use, form a loop with the end of the
extension cord, insert loop into slot in rear of handle,
and place loop over cord hitch (see Figure 9). Gently
pull loop against cord hitch until slack is removed.
Plug extension cord into chain saw cord.

Power Cord

CUTTING WITH THE CHAIN SAW

1. Connect saw to extension cord. Connect 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 10).

4. Make sure your footing is firm. Keep feet apart.
Divide your weight evenly on both feet.

5. When ready to make a cut, push the lockout
button completely forward with the right thumb
and squeeze the trigger (see Figure 10). 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.
It will do the job better and safer at the rate for
which it was intended.

8. 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.

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 se
vere injury or death. See Kickback, pages
4 and 5, 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 perform buck
ing and felling operations at the same
time, provide 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 damage. If tree strikes
utility lines, contact 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.

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 felling. Make
retreat path opposite to planned direction of fall
of tree and at 45° angle (see Figure 11).

Retreat Path

Direction of Fall

-

-

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.

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 12). Follow
directions below to create a felling notch.

1. Make lower notch cut as close to ground as pos
sible. Hold saw so guide bar is horizontal. Cut
1/3 the diameter of tree trunk (see Figure 12).
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 12).

3. Remove tree trunk wedge created by notching
cuts.

B) Felling Cut

1. Make felling cut two inches higher than lower
notch cut and on opposite side of tree (see Figure

12). Keep felling cut parallel to lower notch cut.

2. 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 12). This uncut
portion acts as a hinge. The hinge helps
keep tree from twisting and falling in
wrong direction.

3. 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 re
move 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

• 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.

LIMBING A TREE

WARNING: Avoid kickback. Kickback
can result in severe injury or death. See
Kickback, pages 4 and 5, 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

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.

BUCKING A LOG

WARNING: Avoid kickback. Kickback
can result in severe injury or death. See
Kickback, pages 4 and 5, 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 reduc
ing 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.
Follow directions below to buck a log.

Log Supported On One End

1. Make first cut on underside of log (see Figure

15). Use top of guide bar to make this cut. Cut
1/3 through diameter of log. This cut will keep
section from splintering when cut.

2. Make second cut directly above first cut. Cut
down to meet first cut. This cut will keep log
from pinching guide bar and chain.

Log Supported On Both Ends

1. Make first cut from above log (see Figure 16).
Cut 1/3 through diameter of log. This cut will
keep section from splintering when cut.

2. Make second cut on underside of log, directly
under first cut. Use top of guide bar to make this
cut. Cut up to meet first cut. This will keep log
from pinching guide bar and chain.

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

WARNING: Unplug chain saw from
power source before servicing. Severe injury
or death could occur from electrical shock
or body contact with moving chain.

Normal Guide Bar Maintenance

1. Remove guide bar from chain saw.

2. Remove sawdust from guide bar groove periodi
cally. Use putty knife or wire (see Figure 19).

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 Replacement
Parts and Accessories, page 16, for proper bar.

SHARPENING SAW CHAIN

-

WARNING: Cutting edges on chain
are sharp. Use protective gloves when
handling chain.

WARNING: When cleaning saw body,

• do not submerge saw in any liquids

• do not use products that contain am

-

monia, chlorine, or abrasives

• do not use chlorinated cleaning sol

­vents, 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.

CARE OF GUIDE BAR

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 18). 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.

Guide Bar Groove

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.

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.

4. Hold file guide level. Make sure 30° mark on
file guide is parallel to center of guide bar (see
Figure 20). This will insure that you file cutters
at 30° angle.

5. File from inside towards outside of cutter until
sharp. Only file in this one direction (see Figure

20). Note: Two or three strokes with file should
sharpen cutter.

6. After each cutter is sharpened, move chain for
ward to sharpen next cutter. File all cutters on
one side of chain.

7. Move to other side of chain and repeat process.

Filing Cutter Depth Gauges

The cutter depth gauge clearance is reduced as cutters
are sharpened. After every second or third sharpen
ing, reset cutter depth gauges.

1. Place depth gauge tool (.025") firmly across top
of two cutters. Make sure depth gauge enters slot
in depth gauge tool (see Figure 22).

2. Use medium flat file. File depth gauge level with
depth gauge tool.

3. Remove depth gauge tool. With flat file, round
off front corner of cutter depth gauge (see Figure

23).

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 replacement chain noted in
this manual. Always include new drive sprocket when
replacing chain. This will maintain proper driving of
chain. Note: For proper chain and drive sprocket, see
