SOLUTION
1. Depress switch in 1/2 inch or make sure switch is in the
"ON" position.
2. Have switch replaced.
3. Have capacitor replaced.
4. Correct low line voltage condition. If saw is plugged into an
extension cord, plug saw directly into wall outlet.
5. Have motor replaced.
NOTE: 3 and 4 must be done by a qualified service
technician.
1. Reduce circuit load (turn off other appliances)
2. Correct low line voltage condition. Check line voltage with a
multi-meter. If saw is plugged into an extension cord,
unplug saw from extension cord and plug saw directly to
wall outlet.
3. Reduce load on motor, slow down feed rate of workpiece
being pushed into blade.
4. Have correct fuses on circuit breakers installed by a quali-
fied electrician.
5. Inspect terminals in motor for damaged insulation and
shorted wires and have them replaced. Check all power
lead connections.
1. Correct low line voltage condition. Check line voltage with a
multi-meter. If saw is plugged into an extension cord,
unplug saw from extension cord and plug saw directly to
wall outlet.
2. Have motor replaced.
3. Have capacitor replaced
1. Clean dust and restore normal air circulation around motor.
2. Reduce load on motor.
1. Loosen Handwheel Lock Knob.
2. Clean off tilt and bevel gear assemblies.
1. Clean miter gauge groove and bar.
2. Adjust set-screws in miter gauge bar.
1. Sharpen or replace blade.
