MAINTENANCE
TROUBLESHOOTING
POSSIBLE CAUSE(S)
1. Machine not plugged in.
2. Power switch in OFF position.
3. Power cord is faulty.
4. Fuses or circuit breaker is open.
5. Grinding wheels are blocked.
1. Incorrect line voltage.
2. Motor capacitor has failed
1. Motor is overloaded.
2. Poor air circulation around motor.
3. Overuse in high ambient temperature
room
1. Motor is overloaded.
2. Incorrect line voltage.
3. Motor capacitor has failed
1. Motor is overloaded.
2. Overloaded electrical circuit breaker.
3. Wrong fuse or circuit breaker
4. Defective cord, plug or switch creating a
short circuit.
5. Undersized or excessive length of
extension cord.
6. Grinding wheels are blocked.
LUBRICATION
The bench grinder has sealed lubricated bearings in
the motor housing that do not require any additional
lubrication from the operator.
CLEANING
With the bench grinder unplugged, rotate the grinding
wheels slowly and inspect for any damage or trapped
debris. Periodically blow areas in and around the grinder
to keep the machine and work area clean.
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, oil, grease, etc.
CAUTION
DO NOT USE FLAMMABLE MATERIALS to clean
the bench grinder. A clean dry rag or brush is all that is
needed to remove dust and debris buildup.
CORRECTIVE ACTION
1. Plug power cord into electrical receptacle.
2. Flip switch to ON position.
3. Replace power cord.
4. Overloaded electrical circuit.
5. Unplug machine and remove obstruction.
1. Have a qualified electrician check line for
proper voltage.
2. Replace motor capacitor
1. Reduce pressure on workpiece.
2. Remove any blockage around motor.
3. Reduce runtime to 20 minutes or less
1. Reduce pressure on workpiece.
2. Have a qualified electrician check line for
proper voltage.
3. Replace motor capacitor
1. Reduce pressure on workpiece.
2. Reduce the amount of items on circuit
3. Replace with correct fuse or circuit breaker.
4. Replace with new parts
