Troubleshooting (continued)
Motor
NOTE: Motors used on wood working tools are particularly susceptible to the accumulation of sawdust and wood chips
and should be blown out or “Vacuumed” frequently to prevent interference with normal motor ventilation.
Trouble Probable Cause Remedy
Excessive Noise 1. Motor 1. Have motor checked by qualified service technician.
Repair service is available at your nearest Autho-
rized Service Center.
Motor fails to develop
full power. NOTE: Low
Voltage:
(Power output of motor
decreases rapidly with
decrease in voltage at
motor terminals.
1. Circuit overloaded with lights,
appliances and other motors.
2. Wiring circuit (extension cord)
too long or undersize.
3. General overloading of power
company facilities. (In some
sections of the country, demand
for electrical power may exceed
the capacity of existing generat-
ing and distribution systems.)
4. Incorrect fuses or circuit break-
ers in power line.
1. Do not use other appliances or motors on same cir-
cuit when using the saw.
2. Increase wire sizes, or reduce length of circuit. See
“Motor Specifications and electrical Requirements”
section.
3. Request a voltage check from the power company.
4. Install correct fuses or circuit breakers.
Motor starts slowly or
fails to come up to full
speed
1. Low voltage.
2. Windings burned out or open.
1. Request voltage check from the power company.
2. Have motor repaired or replaced.
Motor overheats 1. Motor overloaded
2. Improper cooling. (Air circula-
tion restricted through motor
due to sawdust, accumulating
inside of saw.)
1. Feed work slower into blade.
2. Clean out sawdust to provide normal air circulation
through motor. See “Maintenance” and “Lubrication”
section.
Motor stalls (resulting in
blown fuses or tripped
circuit breakers)
1. Voltage too low to permit motor
to reach operating speed.
2. Fuses or circuit breakers do not
have sufficient capacity.
1. Request voltage check from the power company.
2. Install proper size fuses or circuit breakers.
Frequent opening of
fuses or circuit breakers
1. Motor overloaded
2. Fuses or circuit breakers do not
have sufficient capacity.
1. Feed work slower into blade.
2. Install proper size fuses or circuit breakers.
Motor runs intermit-
tently, sparks exces-
sively or fails to start
1. Worn or damaged brushes 1. Replace brushes. See “Maintenance” section.
