4

• Wear heavy, long pants, boots and gloves. Do not

wear loose clothing, jewelry, short pants, sandals or
go barefoot. Secure hair above shoulder level.

• The string guard must be in place at all times while

operating the unit. Failure to use the string guard
may cause the clutch to overheat. DO NOT
OPERATE UNIT WITHOUT THE GUARD IN PLACE. 

• Before each use, check that the cutting head is in

good condition and correctly installed, that the
trigger returns automatically to the idle position.

• Before starting, adjust the handle to your size and

make sure that the cutting head is not in contact
with anything.

• Use the unit only in daylight or good artificial light.
• Operate this unit only in a well-ventilated area

outdoors. Carbon monoxide exhaust fumes can be
lethal in a confined area.

• Avoid accidental starting. Be in the starting position

whenever pulling the starting rope. The operator and

cutting head when it is rotating.

short time after the unit is turned off.

is attempted. Do not operate the unit with loose or
damaged parts.

All damaged parts must be replaced immediately.
Follow all the required precautions when
undertaking replacement.

spark arrestors, keep the engine and muffler free of
grass, leaves, excessive grease or carbon buildup.
