Motor - RIDGID WL1200 Owner's Manual

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 and proper op-
eration of the centrifugally-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 maximum power
output.)
Motor starts slowly or
fails to come up to full
speed.
Motor overheats
Starting switch in
motor will not oper-
ate.
Motor stalls
(resulting in blown
fuses or tripped circuit
breakers).
Frequent opening of
fuses or circuit break-
ers.
Probable Cause
1. Motor
1. Circuit overloaded with light,
appliances and other motors.
2. Undersize wires or circuit too
long.
3. General overloading of power
company facilities.
1. Low voltage will not trip relay.
2. Windings burned out or open.
1. Motor overloaded.
2. Improper cooling. (Air circulation
restricted through motor due to
sawdust accumulating inside of
motor).
1. Burned switch contacts (due to
extended hold-in periods caused
by low line voltage, etc.)
2. Shorted capacitor
3. Loose or broken connections.
1. Starting switch not operating.
2. Voltage too low to permit motor
to reach operating speed.
3. Fuses or circuit breakers do not
have sufficient capacity.
1. Motor overloaded.
2. Fuses or circuit breakers do not
have sufficient capacity.
3. Starting switch not operating
(motor does not reach speed).
1. Have motor checked by qualified service technician.
Repair service is available at an Authorized Service Cen-
ter.
1. Do not use other appliances or motors on same circuit
when using the lathe.
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.
2. Have motor repaired or replaced.
1. Take shallower cuts.
2. Clean out sawdust to provide normal air circulation
through motor.
See "Maintenance and Lubrication" section.
1. Have switch replaced and request a voltage check
from the power company.
2. Have capacitor tested and replace if defective.
3. Have wiring checked and repaired.
1. Have switch replaced.
2. Request voltage check from the power company.
3. Install proper size fuses or circuit breakers.
1. Take shallower cuts.
2. Install proper size fuses or circuit breakers.
3. Have switch replaced.
