PROBLEM

CAUSE

SOLUTION

Deep sanding grooves or scars in 

the workpiece. 

1. 

Sanding belt/disc grit is too coarse 

for the desired finish.

1. 

Use a finer-grit sanding accessory.

2. Workpiece sanded across the 

grain.

2. Sand with the grain of the wood.

3. Too much sanding force on the 

workpiece.

3. Reduce pressure on workpiece 

while sanding.

4. Workpiece held still against the 

belt-disc for too long.

4. Keep workpiece moving while 

sanding on the sanding accessory.

Sanding surface clogs quickly.

1. 

Too much pressure against belt/

disc.

1. Reduce pressure on workpiece 

while sanding.

2. Sanding softwood.

2.

 Use different stock, different 

sanding accessories, If you are 

certain of using softwood this will 

occur frequently. Plan on cleaning or

replacing belts/discs frequently.

Burns on workpiece.

1. Using a sanding grit that is too 

fine.

1. Use a coarser-grit sanding 

accessory.

2. Using too much pressure.

2. Reduce pressure on workpiece 

while sanding.

3. Work held still for too long.

3. Do not keep workpiece in one 

place for too long.

Motor will not start - Fuses 

or circuit breakers tripping or 

blowing. 

1. Short circuit in line, cord or plug.

1. Inspect cord or plug for damaged 

insulation and shorted wires.

2. Short circuit in motor or loose 

connections.

2. Inspect all connections on motor 

for loose or shorted terminals and/or 

worn insulation.

3. Incorrect fuses or circuit breakers 

in power line.

3. Install correct fuses or circuit 

breakers or switch tool to an appro-

priately sized circuit.

Motor overheats.

1. Motor overloaded.

1. Reduce load on motor (pressure on 

object being sanded).

2. Extension cord too long and of 

insufficient gauge

2. Utilize an extension cord of appro-

priate gauge and length or plug tool 

directly into outlet.

Motor stalls (resulting in blown 

fuses or tripped circuit)

1. Low voltage.

1. Correct low voltage conditions (for 

example: improper extension cord 

length and/or gauge).

2. Incorrect fuses or circuit breakers 

in power line.

2. Install correct fuses or circuit 

breakers or plug tool into an 

appropriate circuit, matched to an 

appropriate fuse or breaker.

3. Excessive sanding pressure over-

loads motor.

3. Reduce the load on the motor.
