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
instructions in
on pages 3 through 5. Improper use
tion
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.

See page 9 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 service center (see Te chnical 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 www.desatech.com
Important Safety Informa-
• 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 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. 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 causing 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 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.
WARNING: This product contains
chemicals known to the State of California to cause cancer or birth defects, or
other reproductive harm.
WARNING: Some dust created by
power sanding, sawing, grinding, drilling, and other construction 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 ce-
ment and other masonry products
• arsenic and chromium from chemi-
cally-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.
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
overheat. 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.
Example:
SJTW-A or SJTW.
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
severe injury or death. See
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 bucking 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

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 possible. 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 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
•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.

Kickback,
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 mov-
ing 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.
Follow directions below to buck a log.

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 periodically. 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 forward 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 sharpening, 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
Replacement Parts and Accessories, page 16.
