doesn't start after 6 pulls (at the HALF
CHOKE position), move the choke lever to
the FULL CHOKE position and press the
primer bulb 6 times. Squeeze and hold the
throttle trigger and pull the starter rope 2
more times. Move the choke lever to the

STARTING A WARM ENGINE

1. Move ON/STOP switch to the ON posi-
tion.
2. Move the choke lever to the HALF
CHOKE position.
3. Squeeze and hold the throttle trigger.
Keep throttle trigger fully squeezed until
the engine runs smoothly.
4. Pull starter rope sharply until engine runs,
but no more than 5 pulls.
5. Allow engine to run 15 seconds, then move
the choke lever to the RUN position.
NOTE:
If engine has not started, pull starter
rope 5 more pulls. If engine still does not run, it
is probably flooded.

STARTING A FLOODED ENGINE

Flooded engines can be started by placing
the choke lever in the RUN position; then, pull
the rope to clear the engine of excess fuel.
This could require pulling the starter handle
many times depending on how badly the unit
is flooded. If the unit still doesn't start, refer to
TROUBLESHOOTING TABLE.

Cut from your left to your right.
When operating unit, clip shoulder strap onto
clamp, stand as shown and check for the fol-
lowing:
S Wear eye protection and heavy clothing.
S Extend your left arm and hold handlebar
grip with your left hand.
S Hold throttle grip with your right hand with
finger on throttle trigger.
S Keep unit below waist level.
S Keep shoulder strap pad centered on your
left shoulder.

shoulder.
S Without bending over, keep the blade or
trimmer head near and parallel to the ground
and not crowded into material being cut.
OPERATING INSTRUCTIONS FOR
USE WITH TRIMMER HEAD
If engine dies with
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.
Before trimming, bring engine to a speed suffi-
cient to cut material to be trimmed.
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 en-
gine to return to idle speed when not cutting.
To stop engine:
S Release the throttle trigger.
S Move the ON/STOP switch to the STOP
position.
TRIMMER LINE ADVANCE
Advance line by tapping the bottom of the cut-
ting head lightly on the ground while engine is
running at full speed. The metal line limiter
blade attached to the guard will cut the line to
the proper length.
ter line. Other sizes of line will not advance
properly and will result in improper cutting
head function or 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.
Eye Protection

CUTTING METHODS

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 minimum
line wear by not crowding the line into the
cutting area. The right and wrong ways are
shown below.
