OPERATING INSTRUCTIONS
It is recommended that the engine not be
operated for longer than 1 minute at full
throttle.

OPERATING POSITION

EyeProtection
LongP ants
Heavy Shoes
ALWAYSWEAR:
Cut from your right to your left.
WARNING: Alway s wear eye protec-
tion. Never lean over the trimmer head.
Rocksor debris can ricoc het or be thrown into
eyes and face and cause blindness or other
serious injury.
Donot run t he engine at a higher speed than
necessary. The cutting line will cut efficiently
whenthe engine is run at less than full throttle.
At lower speeds, there is less engine noise
andv ibration. The cutting line will last longer
andwill 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.
Tostop engine:
SRelease the throttle trigger.
SMovethe ON/O FF switch to the OFF posi-
tion.

TRIMMER LINE ADVANCE

Thetrimmer line will advanc e approximately 2
inches (5 cm) each time the bottom of the
trimmerhead is tapped on the ground w ith the
engine running at full throttle.
Themost efficient line length is the maximum
length allowed by the line limiter.
Always keep the shield in place when the tool
is being operated.
Toadvance line:
SOperate the engine at full throttle.
SHoldthe trimmer head parallel to and above
the grassy area.
STapthe bottom of the trimmer head lightly on
the ground one time. Approximately 2 inches
(5c m) of line will be advanced wit h each tap.
Always tap the trimmer head on a grass y
area. Tappingon surfaces such as concrete
or asphalt can cause exces sive wear to the
trimmer head.
If the line is worn down to 2 inches (5 cm) or
less,mor e than one tapwill 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.

CUTTINGMETHODS

WARNING : Use minimum speed
anddo not cr owd the line when cutting around
hardobjec ts (rock, gravel, fence posts, etc.) ,
whichcan damage the tr immer head, become
entangled in the line, or be thrown causing a
serious hazard.
SThetip of the line does the c utting. Youwill
achieve the best performance and
minimumline wear by not c rowding the line
into the cutting area. The right and wrong
ways are shown below.

SThe line will easily remove grass and
weedsfrom around walls, fences, tr ees and
flower beds, but it also can cut the tender
bark of trees or shrubs and scar fences.
SFor trimming or scalping, use less than full
throttleto inc rease line life and decrease head
wear, especially:
SDuring light duty cutting.
SNear objects around which the line can
wrap such as small posts, trees or fence
wire.
