TROUBLESHOOTING
Problem
Excessive noise
Motor fails to develop full
power. NOTE: Low voltage
(Power output of motor
decreases rapidly with
decreases 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 to full speed
Motor overheats
Motor stalls (resulting in
blown fuses or tripped circuit
breakers.)
Frequent opening of fuses or
circuit breakers
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 circulation restricted
through motor due to sawdust accumulating
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 technician.
Repair service is available at your nearest Authorized
Service Center.
2. Tighten set screw.
1. Do not use other appliances or motors on same circuit
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 knives.
2. Clean out sawdust to provide normal air
circulation through motor. See "Maintenance and
Lubrication."
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 circuit
when using the jointer.
1. Feed work slower.
2. Install proper size fuses or circuit breakers. See
"Electrical Connection" section.
