Eye Protection
Long Pants
Heavy Shoes
ALWAYS WEAR:
Cut from your right to your left.
WARNING: Alwayswear eyeprotec-
tion. Never lean over the trimmer head.
Rocks ordebris canricochet orbethrowninto
eyes and face and cause blindness o r other
serious injury .
Do not run the engine at a higher speed than
necessary . The cutting line will cut efficiently
whenthe engineis runatlessthan fullthrottle.
At lower speeds, there is less engine noise
and vibration. The cutting line will last longer
and will beless likely to “weld” ontothe 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
Thetrimmerline willadvanceapproximately 2
inches (5 cm) each time the bottom o f the
trimmer headis tappedonthe groundwith 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 placewhen thetool
is being operated.
To advance line:
S Operate the engine at full throttle.
S Hold thetrimmer headparalleltoandabove
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 thanone tap w illbe required 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.
CUTTING METHODS
WARNING: Use minimum speed
and donotcrowdthe linewhencuttingaround
hard objects (rock, gravel, fence posts, etc.),
whichcandamage thetrimmerhead, 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
minimum linewear 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 fr omaroundwalls,fences, tr eesand
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 i ncrease line lif e a nd decrease h ead
wear, especially:
S During light duty cutting.
S Near objects around which the line can
wrap such as small posts, trees or fence
wire.
