TROUBLESHOOTING

CORRECTIVE ACTION
1. Check power line for proper voltage
2. Inspect all lead connections on motor for loose
or open connection
3. Replace switch
4. Replace capacitor
1. Inspect line cord or plug for damaged insulation
and shorted wires
2. Inspect all lead connections on motor for loose
or shorted terminals or worn insulation on wires
3. Install correct fuses or circuit breakers
1. Reduce the load on the power line
2. Increase wire sizes, or reduce length of wiring
3. Request a voltage check from the power com-
pany
Reduce load on motor
1. Inspect connections in motor for loose or
shorted terminals or worn insulation on lead wires
2. Correct the low line voltage conditions
3. Install correct fuses or circuit breakers
4. Reduce load on motor
Ease up on pressure
See operation "Adjusting Belt Tracking"
1. Empty dust collection bag
2. Replace belt
3. Replace impeller
