TROUBLE SHOOTING -- MOTOR (Continued)
TROUBLE PROBABLE CAUSE
Motor starts slowly
or fails to come up
to full speed.
Motor overheats.
Starting relay
will not operate.
Motor stalls
(resulting in blown
fuses or tripped
circuit breakers).
Frequent opening of
fuses or circuit
breakers.
1. Low voltage will not
trip relay.
2. Windings burned out
or open.
3. Starting relay not
operating.
1. Motor overloaded.
2. Improper cooling. (Air
circulation restricted
through motor due to
sawdust, accumulating
inside of saw).
1. Burned relay contacts
(due to extended
hold-in periods caused
by low line voltage, etc.)
2. Saw not in upright
position.
3. Loose or broken
connections.
1. Starting relay not
operating.
2, 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 circuit breakers
do not have sufficient
capacity.
3. Starting relay not
operating (motor does
not reach normal speed).
REMEDY
1. Request voltage check from the power company.
2. Have motor repaired or replaced.
3. Have relay replaced.
1. Feed work slower into blade.
2. Clean out sawdust to provide normal air
circulation through motor.
See "Maintenance and Lubrication" section.
1. Have relay replaced and request a voltage check
from the power company.
2. Place saw in upright position.
3. Have wiring checked and repaired.
1. Have relay replaced.
2. Request voltage check from the power company.
"3. Install proper size fuses or circuit breakers.
1. Feed work slower into blade.
2. Install proper size fuses or circuit breakers.
3. Have relay replaced.
