Troubleshooting (continued)
Motor (continued)
NOTE: Motors used on woodworking tools are particularly susceptible to the accumulation of sawdust and wood chips
and should be blown or “vacuumed” frequently to prevent interference with normal motor ventilation of the centrifugally
operated starting switch.
Trouble Probable Cause Remedy
Motor fails to develop full
power. NOTE: LOW VOLT-
AGE: (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 maxi-
mum power output of
which the motor is capable
and a reduction of 20% in
voltage causes a reduction
of 36% in maximum power
output.)
1. Circuit overloaded with
lights, appliances and other
motors.
2. Undersize extension cord or
extension cord too long.
3. General overloading of
power company facilities.
1. Do not use other appliances or motors on same cir-
cuit when using the Dust Collection System.
2. Increase the wire sizes on extension cords, or
reduce length of extension cords. See “Motor Speci-
fications and Electrical Requirements” section.
3. Request a power check from the power company.
Motor starts slowly or fails
to come up to full speed.
1. Low voltage.
2. Windings burned out or
open.
3. Starting switch will not oper-
ate. (Switch contacts work-
ing properly.) Capacitor is
bad.
1. Request voltage check from the power company.
2. Have motor repaired by a qualified service techni-
cian.
3. Have capacitor replaced by a qualified service tech-
nician.
Motor overheats 1. Motor overloaded.
2. Improper cooling. (Air circu-
lation restricted through
motor due to sawdust, accu-
mulating inside of motor.)
1. Clean out sawdust to provide normal air circulation
through motor. See “Maintenance” section.
Motor stalls (resulting in
blown fuses or tripped cir-
cuit breakers).
1. Voltage too low to permit
motor to reach operating
speed.
2. Fuses or circuit breakers do
not have sufficient capacity.
1. Request voltage check from the power company.
2. Install proper size fuses or circuit breakers.
Frequent opening of fuses
or circuit breakers.
1. Motor overloaded.
2. Fuses or circuit breakers do
not have sufficient capacity.
1. Install proper size fuses or circuit breakers.
