How to start the engine
NOTE: DO NOT BE ALARMED, your engine will smoke the
first time it is started. It is burning off the protective coating
that is on the internal engine parts.
1. Before each use, remove debris from the debris screen. see
fIGuRe 1 In "feATuRes" secTIon. Debris can cause the
engine to overheat. Wipe the debris screen with a cloth or
paper towel.
2. Move the throttle control lever forward to the START or FAST
position.
3. foR 600050B/600050Bce: To start a cold engine, push the
primer button five times. Wait two seconds between each
push of the primer button.
NOTE: Do not use the primer to start a warm engine.
4. Firmly hold the recoil starter handle with your right hand.
see fIGuRe 7.
Trimmer Tips
• Set the throttle control in the FAST position. If the weeds
or grass are tall and thick, operate the trimmer at a slower
walking speed.
• Frequently clean the underside of the trimmer to remove any
grass build up. See the "Maintenance, Service and Storage"
section for details.
• For best results and longer lasting line, use the ends of the
line to do the cutting. This is easily done by moving slowly
through very thick or heavy weeds.
• If the trimmer lines become too short, it will take longer to
complete the job. If the trimmer lines are worn to less than
half their original length, change to a new trimmer line. See
more on how to replace the trimmer line in the "Maintenance,
Service and Storage" section.
• Do not trim on excessively steep slopes. If a slope is difficult
to stand on, do not trim. Do not trim on slopes when the
ground is slippery or wet. Trim across the face of a slope, not
up and down.
• Trimmer head contact to concrete, asphalt and harder
surfaces may create premature wear to the height guide.
5. Pull back sharply on the recoil starter handle. do noT allow
the starter rope to snap back. let the starter rope slowly
rewind as you hold the recoil starter handle.
TIP: on 600050B and
600050Bce models, if
the engine fails to start
after three pulls, push the
primer button two times
and pull the recoil starter
handle again.
