6. Pull starter rope handle sharply until en-
gine sounds as if it is trying to start, but do
not pull rope more than 6 times.
7. As soon as engine sounds as if it is trying to
start, move choke lever to HALF CHOKE.
8. Pull starter rope sharply until engine runs,
but no more than 6 pulls. If the engine
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
HALF CHOKE position and pull the starter
rope until the engine runs, but no more than

6 pulls. If engine still doesn't start,
it may be flooded. Proceed to STARTING A
FLOODED ENGINE.
9. Once the engine starts, allow it to run 10
seconds, then move the choke lever to
the RUN position. Allow the unit to run for
60 more seconds before releasing the
NOTE:
throttle trigger. If engine dies with
the choke lever in the RUN position, move
the choke lever to the HALF CHOKE
position and pull the rope until engine
runs, but no more than 6 pulls.
There is a simplified start reminder (with
illustrations to describe each step) loc-
ated on the air filter cover of the trimmer.
STARTING A WARM ENGINE
1. Move ON/STOP switch to the RUN 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
may be 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.
OPERATING INSTRUCTIONS
OPERATING POSITION
ALWAYS WEAR:
Hearing
protection
Eye protection
Long
Pants
Heavy
Shoes
Cut from your right to your left.
WARNING:
Always wear eye protec-
tion and hearing protection. Never lean over
the trimmer head. Rocks or debris can rico-
chet or be thrown into eyes and face and
cause blindness or other serious injury.
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/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.
WARNING:
Use only 2 mm diameter
line. Other sizes and shapes of line will not ad-
vance properly and will result in improper cut-
ting 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.
