SYMPTOM
Motor will not start.
Motor will not start; fuses
or circuit breakers blow.
Motor fails to develop full
power (power output of
motor decreases rapidly
with decrease in voltage
at motor terminals).
Motor overheats.
Motor stalls (resulting in
blown fuses or tripped
circuit).
Machine slows when
operating.
Blade does not run even-
ly on wheels or runs off.
Blade does not cut even-
ly
Ticking sound when the
saw is running.
Blade contacting table
insert.
Excessive vibration.
POSSIBLE CAUSE
1. Low voltage.
2. Open circuit in motor or loose
connections.
1. Short circuit in line cord or
plug.
2. Short circuit in motor or loose
connections.
3. Incorrect fuses or circuit
breakers in power line.
1. Power line overloaded with
lights, appliances, and other

2. Undersized wires or circuits
too long.
3. General overloading of
power company facilities.
1. Motor overloaded.
2. Air circulation through the
motor restricted.
1. Short circuit in motor or loose

3. Request a power check from the power company.
1. Reduce load on motor.
2. Clean out motor to provide normal air circulation.
1. Inspect connections on motor for loose or shorted
terminals or worn insulation.
2 Correct the low voltage conditions.
3. Install correct fuses or circuit breakers.
4. Reduce load on motor.
Feed workpiece slower.
1. Adjust tracking.
2. Adjust wheel co-planarity.
1. Adjust tension.
2. Replace blade, or have it professionally sharp-
ened.
3. Replace blade, or have it professionally sharp-
ened.
Use file or stone to smooth and round the back of
the blade.
