MAINTENANCE

TROUBLESHOOTING

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)

Motor overheats

Motor stalls (resulting in
blown fuses or tripped 
circuit breakers)

Machine slows down
while operating or 
sandpaper slips on drum

Wood burns while 
sanding; sandpaper not
removing wood

Spindle does NOT travel
completely through 1

stroke

Excessive noise
Note: Normally operating
sander does make some
noise

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 overloaded

1. Short circuit in motor or loose 

connections

2. Low voltage
3. Incorrect fuses or circuit breakers in 

power line

4. Motor overload

1. Applying too much pressure to 

workpiece

2. Spindle knob loose

Sandpaper glazed or loaded with 
sawdust

1. Sawdust build-up below table insert
2. Damaged or loose oscillating 

mechanism

Spindle and motor not aligned properly

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. Tighten spindle knob

Replace sandpaper

1. Remove sawdust with vacuum
2. Inspect mechanism. Contact Sears Service Center 

if necessary

Adjust motor and spindle alignment
