Rocks ordebriscanricochetorbe throwninto
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 ef ficiently
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 le ss likely to “weld” on to th e 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 ADVAN CE
Thetrimmerlinewilladvanceapproximately2
inches (5 cm) each time the bottom o f the
trimmerhead istappedon thegroundwiththe
engine running at full throttle.
The most efficient line length is the maximum
length allowed by the line limiter.
Always keep the shield inplacewhen thetool
is being operated.
To advance line:
S Operate the engine at full throttle.
S Holdthe trimmerheadparalleltoandabove
the g rassy area.
S Tap the bottom of the trimmer head lightly on
the ground one time. Approximately 2 i nches
(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) o r
less, more thanone tapwill berequired toob-
tain the most ef ficient line length.
WARNING: Use only 0.080 ″ (2mm)
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.

S The tip of the line does the cutting. You will
achieve the best performance and
minimumline wear by not crowding the line
into the cutting area. The right and wrong
