Troubleshooting; Lubrication - Craftsman 351.225000 Operator's Manual

LUBRICATION
The shielded ball bearings in this tool are permanently
lubricated at the factory. They require no further lubrication.
• When operation seems stiff, a light coat of paste wax
applied to the belt table and disc table will make it easier to
feed the work while finishing.
• Do not apply wax to the belt platen. Belt could pick up wax
and deposit it on wheels causing belt to slip.
KEEP TOOL IN REPAIR
• If power cord is worn, cut, or damaged in any way, have it
replaced immediately.
• Replace worn abrasives when needed.
• Replace any damaged or missing parts. Use parts list to
order parts.
Any attempt to repair motor may create a hazard unless
repair is done by a qualified service technician. Repair
service is available at your nearest Sears store.
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 decreases rapidly
with decrease in voltage
at motor terminals)
POSSIBLE CAUSE(S)
1. Low voltage
2. Open circuit in motor or loose
connections
3. Defective switch
4. Defective capacitor
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
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
Motor overheats Motor overloaded
Motor stalls (resulting in
blown fuses or tripped
circuit breakers)
1. Short circuit in motor or loose
connections
2. Low voltage
3. Incorrect fuses or circuit breakers in
power line
4. Motor overload
Machine slows down 1. Applying too much pressure to workpiece
while operating 2. Belt Slipping
Abrasive belt runs off top Not tracking properly
wheel
CORRECTIVE ACTION
1. Check power line for proper voltage
2. Inspect all lead connections on motor for loose or
open connection
3. Replace switch
4. Replace capacitor
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
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
Reduce load on motor
1. Inspect connections in motor for loose or shorted
terminals or worn insulation on lead wires
2. Correct the low line voltage conditions
3. Install correct fuses or circuit breakers
4. Reduce load on motor
1. Ease up on pressure
2. Increase V-belt tension
