TROUBLESHOOTING

1. Check spark. Remove sparking plug. Reattach

the sparking plug cap and lay sparking plug on
metal cylinder. Pull the starter rope and watch
for spark at sparking plug tip. If there is no
spark, repeat test with a new sparking plug.

2. Push primer bulb until bulb is full of fuel. If bulb

does not fill, primary fuel delivery system is
blocked. Contact a servicing dealer. If primer
bulb fills, engine may be flooded (see
next item).

3. Remove sparking plug, turn trimmer so spark-

ing plug hole is aimed at the ground. Make sure
lever is in the “WARM START” position and pull
starter cord 10 to 14 times. This will clear
excess fuel from engine. Clean and reinstall
sparking plug. With the throttle trigger fully
depressed, pull starter cord three times with
lever at “WARM START” position. If engine
does not start, move choke lever to “COLD
START” and follow normal starting instructions
in “STARTING AND STOPPING” section. If
engine still fails to start, repeat procedure with
a new sparking plug.
