SYMPTOM
Motor will not start
Motor will not start;
fuses blown or circuit
breakers are tripped
Motor fails to develop
full power (power
output of motor de-
creases rapidly with
decrease in voltage
at motor terminals)
Motor stalls
(resulting in blown
fuses or tripped cir-
cuit breakers)
Feed belt runs
off rollers
Workpieces stalls
while feeding
Workpiece thickness
is not uniform
TROUBLESHOOTING
POSSIBLE CAUSE(S)
1. Low voltage
2. Open circuit in motor or loose
connections
3. Thermal overload protector
activated
1. Short circuit in line cord or plug
2. Short circuit in motor or loose
connections
3. Incorrect fuses or circuit breakers
in power line
4. Thermal overload protector
activated
1. Power line overloaded with lights,
appliances and other motors
2. Undersize wires or circuits too long
3. General overloading of power
company's facilities
1.Motor overload; too much stock
removed per pass
2. Short circuit in motor or loose
connections
3. Low voltage
4. Incorrect fuses or circuit breakers
in power line
Not tracking properly
1. Too much stock removal per pass
2. Not enough tension on feed belt
Drum carriage is not parallel to the
feed table
CORRECTIVE ACTION
1. Check power line for proper voltage
2. Inspect all lead connections on motor for loose
or open connection
3. Push thermal overload button to reset
1. Inspect line cord or plug for damaged insulation
and shorted wires
2. Inspect all lead connections on motor for loose
or shorted terminals or worn insulation on wires
3. Install correct fuses or circuit breakers
4. Push thermal overload button to reset
1. Reduce the load on the power line
2. Increase wire sizes, or reduce length of wiring
3. Request a voltage check from the power
company
1.Set drum height to remove less material per
pass
2. Inspect connections in motor for loose or
shorted terminals or worn insulation on lead
wires
3. Correct the low line voltage conditions
4. Install correct fuses or circuit breakers
See operation, "Adjusting Tracking and Tension of
the Feed Belt"
1. Reduce depth of stock removal per pass
2. See operation, "Adjusting Tracking and Tension
of the Feed Belt"
See operation, "Adjusting Feed Table Parallel to
Drum"
