Troubleshooting

Possible Solution
1. Disconnect power, and inspect line cord and
circuit for electrical shorts and repair; replace
circuit breaker.
2. Test/replace variable speed/power switch.
3. Test/replace motor.
4. Test/replace circuit board.
5. Have the line voltage checked (110–120V
required).
1. Reduce the feed rate and pressure on the
workpiece.
2. Have the line voltage checked (110–120V
required).
3. Inspect/replace motor brushes (refer to Page 28).
1. Inspect/re-tighten/replace.
2. The more solid the mounting surface is, the
less vibration will be felt (solid wood is better
than plywood).
3. Inspect/re-tighten/repair.
1. Properly tension the blade (refer to Page 20).
2. Reduce the feed rate and pressure on the
workpiece.
3. Re-adjust the blade holders so that are aligned
in a straight line with the saw.
1. Properly tension the blade (refer to Page 20).
2. Use more relief cuts for tight turns; reduce feed
rate; do not twist the blade—allow the blade to
do the work.
3. Refer to the Blade Selection Chart on Page
22 and use the right blade for the operation.
4. Reduce the pressure on the workpiece as it
passes through the blade.
5. Select correct blade for task.
