Before trimming, bring engine to a speed suffi-
cient to cut material to be trimmed.
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 Move the ON/OFF switch to the OFF posi-
tion.
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 oper-
ated.
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 as-
phalt 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.),
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 performance and mini-
mum line wear by not crowding the line into
the cutting area. The right and wrong ways
are shown below.

Right Wrong
Line crowded into
work area.
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.

SCALPING -- The scalping technique removes
unwanted vegetation down to the ground. Hold
the bottom of the trimmer head about 3 in. (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 in-
creases 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.
