TROUBLESHOOTING
Problem
Cause
Solution
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.)
Circuit overloaded with lights,
appliances, and other motors
Undersize wires or circuit too long
General overloading of power company
facilities
Do not use other appliances or motors on the same
circuit when using the jointer.
Increase wire sizes, or reduce length of wiring. See
“Motor Specifications and Electrical Requirements”
section.
Request a voltage check from the power company.
Motor starts slowly
or fails to come to full
speed
Windings burned out or open
Drive belt tension too high
Defective start capacitor
Have motor repaired or replaced.
Adjust belt tension.
Have start capacitor replaced.
Motor overheats
Motor overloaded
Improper cooling. (Air circulation
restricted through motor due to
sawdust accumulating inside of motor)
Feed work slower into knives.
Clean out sawdust to provide normal air circulation
through motor. See “Maintenance and Lubrication.”
Motor stalls (resulting in
blown fuses or tripped
circuit breakers.)
Voltage too low to permit motor to
reach operating speed
Fuses or circuit breakers do not have
sufficient capacity
Circuit overloaded with lights,
appliances and other motors
Request voltage check from the power company.
Install proper size fuses or circuit breakers. See
“Electrical Connection” section.
Do not use other appliances or motors on same
circuit when using the jointer.
Frequent opening of
fuses or circuit breakers
Motor overloaded
Fuses or circuit breakers do not have
sufficient capacity
Circuit overloaded with lights,
appliances and other motors
Feed work slower.
Install proper size fuses or circuit breakers. See
“Electrical Connection” section.
Do not use other appliances or motors on same
circuit when using the jointer.
