TROUBLE
Motor starts slowly
or fails to come up
to full speed
Motor overheats
Starting switch in
motor will not
operate
Motor stalls. 1.
(resulting in blown
fuses or tripped 2.
circuit breakers)
Frequent opening o!
fuses or circuit
breakers
PROBABLE CAUSE
1. Low voltage.
2. Windings burned out
or open.
3. Starting switch not
operating.
1. Motor overloaded
2. improper cooling. (Air
circulation restricted
through motor due to
sawdust, accumulating
inside of saw.)
1. Burned switch contacts
(due to extended hold-in
periods caused by low line
voltage, etc.)
2. Shorted capacitor
(when equipped)
3. Loose or broken
connections.
Starting switch not
operating.
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 circuitbreakers
do not have sufficient
capacity.
3. Starting switchnot
