Before further use of the chain saw, a guard or other part that is damaged
should be carefully checked to determine that

Grip saw firmly. Hold the chain saw firmly with both hands when the
motor is running. Use a firm grip with thumbs and fingers encircling the
chain saw handles.

Do not over reach.
(3)
Keep proper footing and balance at all times.
(4)
Don't let the nose of the guide bar contact a log, branch, ground, or other
obstruction.
(5)
Don't cut above shoulder height.
(6)
Use devices such as low kickback chain and special guide bars that
reduce the risks associated with kickback.
(7)
Only use replacement bars and chains specified by the manufacturer.

Power Supply
Connect chain saw to correct voltage, that is, be sure that the voltage
supplied is the same as that specified on the nameplate of the tool.

Replacement Parts
When servicing use only identical replacement parts.
