TROUBLE SHOOTING
-- MOTOR (Continued)
TROUBLE
Motor starts slowly
or fails to come up
to full speed.
Motor overheats.
Starting relay in motor will not
operate.
Motor stalls
(resulting in blown
fuses or tripped
circuit breakers)°
Frequent opening of
fuses or circuit
breakers.
|
| 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
by low line voltage, etc.,)
2 Shorted capacitor (when equipped)
3, Loose or broken connections.
t. 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 clrcuit breakers do not have sufficient capacity,
3_ Starting relay not operating (motor does not reach speed),,
REMEDY
ill i
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 motorr
See "Maintenance and Lubrication" section.
