TROUBLESHOOTING
SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
Motor will not run 1. Defective plug, cord, switch or motor 1.Check wiring, replace defective parts
2. Blown fuse or circuit breaker 2. Check fuse or breaker, replace
Excessive dust in air 1. Leaking bag or hose connection 1. Check filter and collector bag connections.
Check collector hose connections
2. Filter or collector bag leaks 2. Dust trapped under bag clamp or collector bag not
sealed on collar
Excessive impeller noise 1. Large debris or piece or wood in I.D 0 not vacuum metal materials. Turn
impeller housing collector off and let debris settle in
collector bag.
2. Loose impeller 2. Disconnect collector from power source.

2. Defective motor capacitor switch 2.Check switch, replace if necessary
Motor overheats 1. Motor overload 1. Reduce lead by slowing dust production
2. Improper motor cooling 2. Clean sawdust from motor
Tripping circuit breaker or 1. Motor overloaded 1. Reduce load by slowing dust production
fuses 2. Improper capacity of circuit breaker 2. Use proper capacity circuit breaker or
or fuses fuse
