3. Blown overload breaker.
1. Improper mounting of saw.
2. Unsuitable mounting surface.

2. Reduce feed rate. See BLADE REMOVAL
AND INSTALLATION section.
3. Use narrow blade. See BLADE SELECTION
section.
4. Avoid side pressure on blade. See BLADE

again. See POWER SUPPLY section on
Page 10.
2. Call Service Center. Any attempt to repair
this motor may create a HAZARD unless the
repair is done by a qualified technician.

position. Let the motor cool.
