Troubleshooting
Possible Solution
1. Replace fuse/ensure no shorts (Page 32).
2. Ensure correct power supply voltage/circuit size.
3. Test/replace if at fault.
4. Ensure circuit is free of shorts. Reset circuit breaker
or replace fuse.
5. Fix broken wires or disconnected/corroded
connections.
6. Remove/replace brushes (Page 30).
7. Replace switch.
8. Inspect/replace if at fault.
9. Replace motor.
1. Replace blade (Page 22).
2. Only cut wood/ensure moisture if below 20%
(Page 20).
3. Use correct blade/reduce feed rate or depth of cut.
4. Make sure blade installed correctly, tighten lock
knobs (Page 22).
5. Inspect and replace if at fault.
6. Test and replace if at fault.
7. Replace motor brushes (Page 30).
8. Clean motor, let cool, reduce workload.
9. Move machine closer to power supply; use shorter
extension cord.
10. Replace motor.
1. Replace damaged or missing bolts/nuts or tighten if
loose.
2. Replace warped/bent blade; resharpen dull blade.
3. Adjust feet, shim or tighten mounting hardware.
4. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
1. Reduce feed rate and pressure on workpiece.
2. Adjust blade holders so they are perpendicular.
1. Use relief cuts for tight turns; reduce feed rate; do
not twist blade.
2. Refer to Blade Selection Chart, and use correct
blade for operation (Page 23).
3. Reduce pressure on workpiece.
1. Position arm parallel with table (Page 24).
2. Rotate motor until blade perpendicular with table.
