TROUBLE
ill i
Motor starts slowly
or fails to come up
to full speed.
Motor overheats.
Starting relay in
motor will not
operate.
PROBABLE CAUSE
1, Low voltage will not
trip relay,,
2, Windings burned out
or open.
3. Starting relay not
operating.
t, Motor overloaded
2._Improper cooling, (Air
circulation restricted
through motor due to
sawdust, accumulating
inside of saw).
t. Burned relay contacts
(due to extended
hold-in periods caused
by low line voltage, etc.,)
2 Shorted capacitor
(when equipped)
3, Loose or broken
connections.
Motor stalls t. Starting relay not
(resulting in blown operating,,
fuses or tripped 2. Voltage too low to permit
circuit breakers)° motor to reach operating
3

capacity,
Starting relay not
operating (motor does
not reach speed),,
REMEDY
1, Request voltage check from the power company,
