Troubleshooting
Motor
NOTE: Motors used on wood-working tools are particularly susceptible to the accumu-
lation of sawdust and wood chips and should be blown out or "vacuumed" frequently to
prevent interference with normal motor ventilation and proper operation of the centrifu-
gally-operated starting switch.
Trouble
Excessive noise
Motor fails to
develop full power.
Note Low Voltage:
Power output of
motor decreases
rapidly with
decrease in voltage
at motor terminals.
For example, a
reduction of 10% in
voltage causes a
reduction of 19% in
maximum power
output of which the
motor is capable,
and a reduction of
20% in voltage
causes a reduction
of 36% in maxi-
mum power output
Motor starts slowly
or fails to come up
to full speed.
Motor overheats
Probable Cause
1. Motor
1. Circuit overloaded
with light, appli-
ances and other
motors.
2. Undersize wires or
circuit too long.
3. General overload-
ing of power com-
pany facilities.
1. Low voltage.
2. Windings burned
out or open.
3. Starting switch not
operating.
1. Motor overloaded.
2. Improper cooling
(air circulation
restricted through
motor due to saw-
dust accumula-
tion).

Remedy
1. Have motor checked by quali-
fied service technician. Repair
service is available your near-
est Authorized Service Center
store.
1. Do not use other appliances or
motors on same circuit when
using the saw.
2. Increase wire sizes, or reduce
length of wiring. See "Motor
specifications and Electrical
Requirements" section.
3. Request a voltage check from
the power company.
1. Request voltage check from the
power company. Check size of
circuit wiring.
2. Have motor repair or replaced.
3. Blow out sawdust from motor.
Have motor repaired.
1. Feed work slower into blade.
2. Clean out sawdust to provide
normal air circulation through
motor. See "Maintenance" sec-
tion.
