WARNING: Always weareyeprotec-
tion. Never lean over the trimmer head.
Rocks ordebris canricochet orbe 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 efficiently
whentheengine isrunat lessthan fullthrottle.
At lower speeds, there is less engine noise
and vibration. The cutting line will last longer
and will be les s likely to “weld” ontothespool.
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
Thetrimmerline w illadvance approximately 2
inches (5 cm) each time the bottom o f the
trimmer headis tappedon theground w iththe
engine running at full throttle.
The most efficient line length is the maximum
length allowed by the line limiter.
Always keep the shield in placewhen the tool
is being operated.
To advance line:
S Operate the engine at full throttle.
S Hold thetrimmer headparallelto andabove
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 onetap will berequired toob-
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.
