TROUBLESHOOTING
GAS ENGINE WON’T START:
1. Check for sufficient fuel.
2. Check oil level. Engines have an “Oil Alert” feature, which prevents them from starting when the oil level is low.
3. Was engine choked when starting?
4. Is engine flooded?
5. Check spark plug. (Clean and check gap)
6. If engine still will not start, consult the engine owner’s manual or take it to an authorized service center.
ELECTRIC ENGINE WON’T START:
1. Make sure the motor is wired correctly for the supply voltage. Wiring information can be found on the motor nameplate
or inside the wiring box.
2. Check plugs, fuses, and circuit breakers. The circuit should be rated for AT LEAST the full load current of the motor.
3. Make sure the mixer is not jammed or overloaded when starting up. This can lead to repeated blown fuses or tripped
circuit breakers.
ENGINE/MOTOR STARTS BUT PADDLES WILL NOT TURN:
HYDRAULIC DRIVE MODELS
1. Make sure the mixer is not jammed. A broken mixing arm can prevent the entire shaft from turning.
2. Check the adjustment on the flow control.
3. Make sure the shear bolt is still intact on the coupler between the hydraulic motor and the drum shaft.
4. Verify hydraulic fluid levels and check the filter.
MECHANICAL DRIVE MODELS
1. Check the belts for wear, oil, or grease. Replace them if necessary.
2. Loosen the bolts that hold the engine in place. Slide the engine away from the drive shaft to tighten the belts;
then re-tighten the bolts. Be careful not to over-tighten the belts or the clutch will not disengage.
3. Make sure the clutch mechanism is moving the idler pulley or engine base when the clutch lever is moved.
4. Make sure that gears are meshing and not slipping on the drive or drum shafts.
