OPERATING INSTRUCTIONS
It is recommended that the engine not be
operated for longer than 1 minute at full
throttle.
OPERATING POSITION
Eye protection
Long pants
Heavy shoes
ALWAYS WEAR:
Cut from your right to your left.
WARNING:
Always wear eye protec-
tion. Never lean over the trimmer head.
Rocks or debris can ricochet or be thrown into
eyes and face and cause blindness or other
serious injury.
Do not run the engine at a higher speed than
necessary. The cutting line will cut efficiently
when the engine is run at less than full throttle.
At lower speeds, there is less engine noise and
vibration. The cutting line will last longer and will
be less likely to “weld” onto the spool.
Always release the throttle trigger and allow the
engine to return to idle speed when not cutting.
To stop engine:
S
Release the throttle trigger.
S
Push and release the engine ON/STOP
switch.
TRIMMER LINE ADVANCE
The trimmer line will advance approximately 2
inches (5 cm) each time the bottom of the
trimmer head is tapped on the ground with the
engine running at full throttle.
The most efficient line length is the maximum
length allowed by the line limiter.
Always keep the shield in place when the tool
is being operated.
To advance line:
S
Operate the engine at full throttle.
S
Hold the trimmer head parallel to and above
the grassy area.
S
Tap the bottom of the trimmer head lightly on
the ground one time. Approximately 2 inches
(5 cm) of line will be advanced with each tap.
Always tap the trimmer head on a grassy
area. Tapping on surfaces such as concrete
or asphalt can cause excessive wear to the
trimmer head.
If the line is worn down to 2 inches (5 cm) or
less, more than one tap will be required to ob-
tain the most efficient line length.
WARNING:
Use only 0.080
″
(2 mm)
diameter line. Other sizes of line will not ad-
vance properly and can cause serious injury.
Do not use other materials such as wire,
string, rope, etc. Wire can break off during
cutting and become a dangerous missile that
can cause serious injury.
CUTTING METHODS
WARNING:
Use minimum speed
and do not crowd the line when cutting around
hard objects (rock, gravel, fence posts, etc.),
