WARNING: Always weareyeprotec-

Rocks ordebris canricochetor bethrowninto
eyes and face and cause blindness o r other
serious injury .
When operating unit, stand as shown and
check for the following:
S W ear eye protection and heavy clothing.
S Holdtrigger handlewithyourrighthandand
assit handle with left hand.
S Keep unit below waist level.
S Cut only from your left to your r ight to
ensure debris is thrown away from you.
Without bending over, keep line near and
parallel to the ground and not crowded into
material being cut.
Do not run the engine a t a higher speed than
necessary. The cutting line will cut efficiently
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 less 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 Move the ON/OFF switch to the OFF posi-
tion.
TRIMMER LINE ADVANCE
Thetrimmerlinewilladvanceapproximately 2
inches (5 cm) each time the bottom o f the
trimmer headistapped ontheground withthe
engine running at full throttle.
The most efficient line length is the maximum
length allowed by the line limiter . Always keep
the shield in place when the tool is being oper-
ated.
To advance line:
S Operate the engine at full throttle.
S Hold thetrimmerhead paralleltoandabove
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 as-
phalt can cause excessive wear to the trimmer
head.If the line is worn down to 2 inches (5 cm)
or less, more than o ne tap will berequired toob-
tain th e most ef fi cient line length.
WARNING: Use only 0.095″ (2.4
mm) diameter line. Other sizes of line will not
advance properly and can cause serious
injury. Do not use other materials such as
wire, string, rope, etc. Wire can break off dur-
ing cutting and become a dangerous missile
that can cause serious injury.
CUTTING METHODS
WARNING: Use minimum speed
anddo notcrowdthelinewhen cuttingaround
hard objects (rock, gravel, fence posts, etc.),
whichcandamagethetrimmerhead,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 mini-
mum linewear by not crowding the lineinto
the cutting area. The right and wrong ways
are shown below.
