MAINTENANCE AND REPAIR INSTRUCTIONS
If the chain and
motor fail to stop
when the Chain Brake® is engaged, take
the saw to a Sears or other qualified service
dealer. Do not use the saw if the Chain
Brake® is not in proper working order.
WARNING:
CHAIN BRAKE® TEST
Before cutting with your saw, the Chain Brake® should be
tested as follows:
A. Make sure the Chain Brake® is disengaged (Fig. 26).
B. Place the saw on a firm, flat, dry surface that is clear
of any debris. Do not let the saw come in contact with
any objects.
C. Plug the unit into the power source.
D. Grasp the front handle (not the Chain Brake®/Hand
Guard Lever) with your left hand. Thumb and fingers
should encircle the handle.
E. Grasp the rear handle with your right hand. Thumb
and fingers should encircle the handle.
F. Slide the LOCK/OFF button with your right thumb.
Squeeze the trigger with your index finger (Fig. 7).
G. While the motor is running, activate the Chain Brake®
by rolling your left hand forward against the lever.
H. Chain and motor should stop abruptly.
A cord that is hot to
the touch is over-
loaded.
CAUTION:
Your double insulat-
ed appliance has no
serviceable parts inside. Do not attempt to
repair it yourself. For service information,
take the saw to a Sears or other qualified
service dealer.
WARNING:
Do not operate your
chain saw in a wet or
damp environment. Do not expose the saw to
rain, snow or sleet. Moisture will cause short
circuits. Replace or repair any damaged or
frayed extension cords before using your saw.
Keep the cord away from the cutting area and
position the cord so that it will not be caught
on branches or other objects during cutting.
WARNING:
EXTENSION CORDS
When using an electric chain saw, plug it into the exten-
sion cord only when you are ready to cut wood. Connect
the extension cord to a 110/120 voltage outlet. Refer to
the Electrical Safety Warnings section.
DOUBLE INSULATION
WHEN SERVICING, USE ONLY IDENTICAL REPLACE-
MENT PARTS.
Information
Do not use if the cord or plug is damaged. Your appliance
is double insulated to help protect against electric shock.
Double insulation construction consists of 2 separate “lay-
ers” of electrical insulation.
Appliances built with this insulation system are not intend-
ed to be grounded. As a result, the extension cord used
with your appliance can be plugged into any conventional
120 volt electrical outlet.
Normal safety precautions must be observed when operat-
ing an electrical appliance. The double insulation system is
only for added protection against injury resulting from a
possible internal electrical insulation failure.
In this double insulated appliance, 2 systems of insulation,
instead of grounding, are provided. No grounding means is
provided on a double insulated appliance, nor should a
means for grounding be added to the appliance. No serv-
iceable parts are inside. A double insulated appliance is
marked with the words, “DOUBLE INSULATION” or “DOU-
BLE INSULATED.” The symbol (square within a square)
may also be marked on the appliance.
Maintenance
1. Place switch in OFF position and unplug the power
supply before the appliance is serviced, cleaned, or
maintenance is performed.
2. Keep the air intake clean and air vents free of debris to
avoid overheating the motor.
3. Clean with a damp sponge and mild soap. Do not
squirt with a water hose or douse with water or other
liquids.
4. Inspect the saw chain for proper tension before each
use and frequently during cutting. Sharpen as required.
Refer to the Chain Sharpening in
Maintenance and
Repair Instructions.
5. Clean the guide bar and bar pad to ensure free path
for oil.
6. No motor lubrication is necessary. The motor is
equipped with lifetime lubricated bearings.
7. If the saw does not operate, turn switch to OFF posi-
tion and disconnect the extension cord, first from the
power supply, then from the saw. Check the power
supply for blown fuses or tripped circuit breakers. If it
still does not operate,
take the saw to a Sears or
other qualified service dealer.
NOTE:
Do not attempt to repair saw yourself. No
serviceable parts are inside.
