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.
CUTTING METHODS
WARNING:
and do not crowd the line when cutting around
hard objects (rock, gravel, fence posts, etc.),
which can damage the trimmer head, become
entangled in the line, or be thrown causing a
serious hazard.
S The tip of the line does the cutting. You will
achieve the best
minimum line wear by not crowding the line
into the cutting area. The right and wrong
ways are shown below.
Tip of the line
does the cutting.
Right
S The line will easily remove grass and
weeds from around walls, fences, trees and
flower beds, but it also can cut the tender
bark of trees or shrubs and scar fences.
S For trimming or scalping, use less than full
throttle to increase line life and decrease head
wear, especially:
S During light duty cutting.
S Near objects around which the line can
wrap such as small posts, trees or fence
wire.
S For mowing or sweeping, use full throttle for
a good clean job.
TRIMMING - - Hold the bottom of the trimmer
head about 3 inches (8 cm) above the ground
and at an angle. Allow only the tip of the line to
make contact. Do not force trimmer line into
work area.

Wrong
SCALPING - - The scalping technique re-
moves unwanted vegetation down to the
ground. Hold the bottom of the trimmer head
about 3 inches (8 cm) above the ground and
at an angle. Allow the tip of the line to strike the
ground around trees, posts, monuments, etc.
This technique increases line wear.
Scalping
MOWING - - Your trimmer is ideal for mowing
in places conventional lawn mowers cannot
reach. In the mowing position, keep the line
parallel to the ground. Avoid pressing the
head into the ground as this can scalp the
ground and damage the tool.
SWEEPING - - The fanning action of the rotat-
ing line can be used for a quick and easy
clean up. Keep the line parallel to and above
the surfaces being swept and move the tool
from side to side.
