TROUBLESHOOTING
ENGINE WON’T START:
1. Check safety switches. Tether should be attached and weight pushed away from operator. Check for
loose connections.
2. Check for sufficient fuel.
3. Check oil level. Engines have an “Oil Alert” feature, which prevents them from starting when the oil
level is low.
4. Was engine choked when starting?
5. Is engine flooded?
6. Check spark plug. (Clean and check gap)
7. If engine still will not start, consult the engine owner’s manual or take it to an authorized service
center.
BLADES WON’T MOVE OR ARE SLOWER THAN NORMAL:
1. Check the throttle cable to make sure it is allowing the engine throttle to move freely in its entire
range of motion.
2. Check the v-belt. Replace if worn.
3. Check the clutch. Replace if needed.
4. Check the gear box.

THE PITCHING ARMS” section for more information.
