Cut from yourrighttoyourleft.
Do not runthe engine at a higher
speed than necessary. The cutting line
willcut efficiently when the engine is
run at less than fullthrottle. At lower
speeds, there is less engine noise and
vibration. The cuttingline will last
longer and will be less likely to "weld"
onto the spool.
If the trimmer head does not turn when
the engine is in operation, make sure
the drive shaft housing is properly
seated in engine shroud.
Always release the throtUetrigger and
allow the engine to return to idle speed
when not cutting.
To stop engine:
* Release the throttle trigger.
• Press and holdthe ON/STOP switch
inthe STOP position.
TRIMMER LINE ADVANCE
The trimmer line will advance approxi-
mately 2 in. (5 cm) each time the bot-
tom of the tdmmer head is tapped on
the ground wJthrthe engine running at
full throttle.
The most efficient linelength is the
maximum lengthallowed by the line
limiter.
Always keep the shleld in place when
the toolis being operated.
To Advance Line:
, Operate the engine at full throttle.
, Holdthe trimmer head parallel to and
above the grassy area.
. Tap the bottom of the trimmer head
lightlyon the groundone time. Ap-
proximately 2 in. (5 cm) of line will be
advanced with each tap.
Alwaystap the trimmer head on a
grassy area. Tapping on surfaces such
as concrete or asphalt can cause ex-
cessive wear to the trimmer head.
If the line isworn downto 2 in. (5 cm)
or less, more than one tap will be re-
quired to obtain the most efficient line
length.
WARNING; Use only .065" (1.6 ram)
diameter line. Other sizes of line will
not advance properlyand can cause
serious injury.Do notuse other mated-
als such as wire, stdng, rope, etc. Wire
can break off during cuttingand be-
come a dangerous missile that can
cause serious injury.
CUTrlNG 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 seri-
ous hazard.
• The tip ofthe line does the cutting.
You wilt achfeve the best perform-
ance and minimumline wear by not
crowdingthe line into the cutting
area. The rightand wrong ways are
shown below.

, 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. To help avoid darn-
age especially to delicate vegetation
or trees with tender bark, shorten line
to 4-5 in. (10-13 cm) and use at less
than full throttle.
• For trimming or scalping, use tess
than full throttle to increase line life
and decrease head wear, especially:
• During light duty cutting.
• Near objects around which the fine
can wrap such as small posts,
trees or fence wire.
• For mowing or sweeping, use full
throttle for a good cleanjob.
