Motor - RIDGID JP0600 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.
Trouble
Excessive noise
Motor fails to develop full
power. NOTE: Low volt-
age (Power output of
motor decreases in volt-
age 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 capa-
ble, and a reduction of
20% in voltage causes a
reduction of 36% in maxi-
mum power output.)
Motor starts slowly or fails
to come to full speed
Motor overheats
Motor stalls (resulting in
blown fuses or tripped cir-
cuit breakers.)
Frequent opening of
fuses or circuit breakers
Probable Cause
1. Motor
2. Pulley set screw is loose.
1. Circuit overloaded with
lights, appliances and other
motors.
2. Undersize wires or circuit
too long.
3. General overloading of
power company facilities.
1. Windings burned out or
open.
2. Drive belt tension too high.
3. Defective start capacitor
1. Motor overloaded
2. Improper cooling. (Air circu-
lation restricted through
motor due to sawdust accu-
mulating inside of motor.)
1. Voltage too low to permit
motor to reach operating
speed.
2. Fuses or circuit breakers do
not have sufficient capacity.
3. Circuit overloaded with
lights, appliances and other
motors.
1. Motor overloaded
2. Fuses or circuit breakers do
not have sufficient capacity.
3. Circuit overloaded with
lights, appliances and other
motors.
1. Have motor checked by qualified service techni-
cian. Repair service is available at your nearest
Authorized Service Center.
2. Tighten set screw.
1. Do not use other appliances or motors on same cir-
cuit when using the jointer.
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. Have motor repaired or replaced
2. Adjust belt tension
3. Have start capacitor replaced
1. Feed work slower into blade.
2. Clean out sawdust to provide normal air circulation
through motor. See "Maintenance and Lubrication"
section.
1. Request voltage check from the power company
2. Install proper size fuses or circuit breakers. See
"Electrical Connection" section
3. Do not use other appliances or motors on same cir-
cuit when using the jointer.
1. Feed work slower
2. Install proper size fuses or circuit breakers. See
"Electrical Connection" section
3. Do not use other appliances or motors on same cir-
cuit when using the jointer.
