ALWAYS WEAR:
Cut from your right to your left.
WARNING:
Always wear eye protec-
tion and hearing protection. Never lean over
the trimmer head. Rocks or debris can rico-
chet 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
Move the ON/OFF switch to the OFF posi-
tion.
TRIMMER LINE ADVANCE
The trimmer line will advance approximately 2
in. (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 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 5 cm or less, more
than one tap will be required to obtain the
most efficient line length.
WARNING:
Use only 2 mm diameter
line. Other sizes and shapes of line will not ad-
vance properly and will result in improper cut-
ting head function or 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.

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:
