OPERATING INSTRUCTIONS
It is recommended that the engine not be
operated for longer than 1 minute at full
throttle.
OPERATING POSITION
Cut only from your left to your right.
ALWAYS WEAR:
Long Pants
Heavy shoes
Eye Protection
Hearing
Protection
WARNING:
Always wear eye protec-
tion. Never lean over the trimmer head.
Rocks or debris can ricochet or be thrown into
eyes and face and cause blindness or other
serious injury.
When operating unit, stand as shown and
check for the following:
S
Wear eye protection and heavy clothing.
S
Hold trigger handle with your right hand and
assit handle with left hand.
S
Keep unit below waist level.
S
Cut only from your left to your right 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 at 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” onto the 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
The trimmer line will advance approximately 2
inches (5 cm) each time the bottom of the
trimmer head is tapped on the ground with 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 place when the tool is being oper-
ated.
To advance line:
S
Operate the engine at full throttle.
S
Hold the trimmer head parallel to and above
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 one tap will be required to ob-
tain the most efficient 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
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
serious hazard.
S
The tip of the line does the cutting. You will
achieve the best performance and mini-
mum line wear by not crowding the line into
the cutting area. The right and wrong ways
are shown below.
