IMPORTANT SAFETY INSTRUCTIONS
WARNING: WHEN USINGAN ELECTRIC CHAIN
SAW, BASIC SAFETY PRECAUTIONS SHOULD
ALWAYS BE FOLLOWED T REDUCE THE RISK
OF FIRE, ELECTRIC SHOCK, AND INJURY TO
PERSONS, INCLUDING THE FOLLOWING:
READ ALL INSTRUCTIONS (1)
- Keep Work Area Clean
Cluttered areas invite injuries. Do not start cutting until
you have a clear work area, secure footing, and a planned
retreat path from the falling tree.
- Consider Work Area Environment
Use extreme caution when cutting small size brush and
saplings because the slender material may catch the saw
chain and be whipped toward you or pull you off balance.
Do not operate a chain saw in a tree unless specically
trained to do so. 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 bers is released. Don't expose
chain saw to rain (3). Don’t use chain saw in damp or wet
locations. Do not use chain saw in presence of ammable
liquids or gases.
- Guard Against Electric Shock
Prevent body contact with grounded surfaces. For ex-
ample: metal pipes, wire fences.
- Keep Children Away
Do not let visitors contact chain saw or extension cord.
All visitors should be kept away from work area (4).
- Store Idle Chain Saw
When not in use, chain saws should be stored in a dry
and high or locked up place-out of the reach of children.
When storing saw, use a scabbard or carrying case.
- Don’t Force Chain Saw
It will do the job better and safer at the rate for which it
was intended.
- Use Right Tool
Cut wood only. Don’t use chain saw for purpose not
intended - for example - Don’t use chain saw for cutting
plastic, masonry non- wood building materials.
- Dress Properly
Do not wear loose clothing or jewelry. They can get caught
in moving parts. Rubber gloves and non-skid footwear are
recommended when working outdoors. Wear protective
hair covering to contain long hair.
- Use Safety Glasses
Also use safety footwear; snug tting clothing; protective
gloves; hearing and head protection (5).
- Carrying Saw
Carry the chain saw by the front handle with the saw
stopped, nger off the switch, the guide bar and saw
chain, covered with the chain protection, to the rear.
- Maintain Chain Saw With Care
Inspect chain saw cords periodically and if damaged,
have repaired by authorized service facility. Keep cord
clear of the chain and operator at all times. Never carry
saw by the cord or pull it to disconnect from receptacle. 5

Keep cord from oil and sharp edges. Inspect extension
cords periodically and replace if damaged. Keep tools
sharp and clean for better and safer performance. Fol-
low instructions for lubricating and changing accessories.
Keep handles dry, clean, and free from oil and grease.
- Disconnect Chain Saw
Disconnect chain saw when not in use, before servicing,
and when changing accessories and attachments, such
as saw chain and guard (6).
- Outdoor Use Extension Cords
Use only extension cords intended for use outdoors and
so marked.
Route the power cord in such a way that in cannot get
caught in branches or other objects during sawing.
- Stay Alert
Watch what you are doing. Use common sense. Do not
operate chain saw when you are tired. Keep all parts of
the body away from the saw chain when the motor is
operating. Before you start the saw, make sure the saw
chain is not contacting anything.
- Check Damaged Parts
Before further use of the chain saw, a guard or other part
that is 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 center unless other-
wise indicated elsewhere in this instruction manual. Have
defective switches be replaced by authorized service
center. Do not use chain saw if the switch does not turn
the saw on and off. Do not operate a chain saw that is
damaged, improperly adjusted, or is not completely and
securely assembled (7). Be sure that the saw chain stops
moving when the trigger is released.
- Guard Against Kickback
WARNING: KICKBACK may occur when the nose or
tip of the guide bar touches an object (8), 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. The following precautions should be followed to
minimize kickback:
- Always grip each handle with the thumb and ngers
encircling the handle as illustrated in (9). If a manual
oiler control is provided additional or modied instruc-
tions regarding its use shall be provided.
- Do not over reach.
- Keep proper footing and balance at all times.
- Don’t let the nose of the guide bar contact a log,
branch, ground, or other obstruction.
- Don’t cut above shoulder height (10).
- Use devices such as low kickback chain, chain brakes
and special guide bars that reduce the risks associated
with kickback.
- Only use replacement bars and chains specied by
the rnanufacturer.

- Power Supply
Connect chain saw to correct voltage, that is, be sure that
the voltage supplied is the same as that specied on the
nameplate of the tool (11).
- Replacement Parts
When servicing, use only identical replacement parts
(11).
- Polarized Plugs
To reduce the risk of electric shock, this equipment has
a polarized plug (one blade is wider than the other). This
plug will t in a polarized outlet only one way. If the plug
does not t fully in the outlet, reverse the plug. If it still
does not t, contact a qualied electrician to install the
proper outlet. Do not change the plug in any way.
- Wear ear protectors during operation.
- Before making a felling cut, remove dirt, stones, loose
bark, nails, staples and wire from the tree.
- Secure the log so that it will not rol or move suddenly
during operation.
- AVOID UNINTENTIONAL STARTING. Don’t carry
plugged-in tool with nger on switch. Be sure switch
is OFF when plugging in.
- Attention! Do not expose this tool to rain (12) and pull
plug immediately if the supply cable is damaged or
cut (13).
-The chain saw must not be left outdoors during rain
and it must not be used when wet.
VOLTAGE WARNING:
Before connecting the tool to a power source (recep-
tacle outlet, etc.) be sure the voltage supplied is the
same as that specied on the nameplate of the tool. A
power source with voltage greater than that specied
for the tool can result in SERIOUS INJURY to the user
- as well as damage to the tool. If in doubt, DO NOT
PLUG IN THE TOOL. Using a power source with voltage
less than the nameplate rating is harmful to the motor.
Use of Extension Cord
If the extension cord is intended to be used outdoors, the cord
shall be marked with the sufx W-A following the cord type
designation, for example - SJTW-A, to indicate it is accept-
able for outdoor use. Use an extension cord heavy enough
to carry the current the tool will draw. Undersized cord will
cause a drop in line voltage resulting in loss of power and
over-heating. Make sure the extension cord is in good condi-
tion before using. Keep the cord away from the cutting area
and to position cord so that it will not be caught on branches,
and the like, during cutting. Use the table below to determine
the proper wire size required in the extension cord.
Contact DOLMAR Authorized or Factory Service Center if a
proper extension cord cannot be found.

Checking the chain tension
The chain has the proper tension when it lies against the bottom
edge of the guide bar and can be easily pulled by hand about
2-4 mm (about 1/8") up from the guide bar.
Check the chain tension frequently - new chains tend to get
longer during use!
When checking the chain tension the motor must be switched
off and the power supply plug pulled out.If the chain is too
loose: Loosen the sprocket guard quick tightener by about a
quarter turn. Tighten the chain as described under “Tightene-
ing the saw chain.”
HINT:
Use 2 or 3 saw chains alternately for even wear of the chains,
sprocket and guide bar running surfaces.
In order to guarantee a uniform wear of the groove in the bar the
bar should be turned over whenever replacing the chain.
Chain brake
The electric chain saw comes with an chain brake as standard
equipment. Kickback occurs due to contact of the guide bar tip
with wood (see SAFETY PRECAUTIONS, page 5).
Run-out brake
The electric chain saw come with a run-out brake as standard
equipment.
The run-out brake ensures that the chain comes to a stop
immediately when the ON/OFF switch is released, thus
preventing the chain from continuing to run and presenting a
hazard.
Testing of the run-out brake is described on page 14.
Chain and run-out brake maintenance
The brake systems are very important safety features, and
like any other part they are subject to a certain amount of
wear. Regular inspection and maintenance is important for
your personal safety, and can be properly performed only
by a DOLMAR service center.
Engaging the chain brake (braking)
If the kickback is strong enough the sudden acceleration of the
guide bar combined with the inertia of the hand guard (1) will
automatically actuate the chain brake.
To engage the chain brake manually, simply push the hand
guard (1) forward (towards the tip of the saw) with your left
hand (arrow 2).
Releasing the chain brake
Pull the hand guard (1) towards you (arrow 3) until you feel it
catch. The brake is now released.
Note:
When the chain brake is actuated the power supply to the
motor will be cut off. Testing of the chain brake is described
on page 14.
