TROUBLESHOOTING - 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
Excessive noise.
rMotor fails to develop
lull 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
maximum power
output.)
PROBABLE CAUSE
1. Motor
1. Circuit overloaded with
lights, appliances and other
motors.
2. Undersize wires or circuit
too long.
3. General overloading of
ix)we r company facilities.
(in some sections of the
country, demand for elec-
trical power may exceed
the capacity of existing
f generating and distribution
systems.)
REMEDY
1. Have motor checked by qualified service techni-
cian. Repair service is available at your nearest
Sears 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 Require
meres" section.
3, Request a voltage check from the power company.
.
incorrect fuses or circuit
breakers in power line.
4. Install correct fuses or circuit breakers.
