W1730 Oscillating Edge Sander
Troubleshooting
This section covers the most common Model W1730 Oscillating Edge Sander problems. DO NOT make any
adjustments until the Model W1730 is unplugged and moving parts have come to a complete stop.
SYMPTOM POSSIBLE CAUSE CORRECTIVE ACTION
Motor will not start. 1. Low voltage.
2. Open circuit in motor or loose
connections.
1. Check power supply for proper voltage.
2. Inspect all lead connections on motor and magnetic
switch for loose or open connections.
Fuses or circuit breakers
trip open. 1. Short circuit in line cord or plug.
2. Short circuit in motor or loose
connections.
3. Incorrect fuses or circuit breakers
in power supply.
1. Inspect cord or plug for damaged insulation and
shorted wires and replace extension cord.
2. Inspect all connections on motor for loose or
shorted terminals or worn insulation.
3. Install correct fuses or circuit breakers.
Motor overheats. 1. Motor overloaded.
2. Air circulation through the motor
restricted.
1. Reduce load on motor.
2. Clean out motor to provide normal air circulation.
Motor automatically shuts
off (possibly resulting in
blown fuse or tripped
circuit breaker in the
magnetic switch box, or in
power supply circuit). 1. Thermal Protection Circuit Breaker
amperage is set too low.
2. Short circuit in motor or loose
connections.
3. Low power supply voltage.
4. Incorrect fuses/circuit breakers.
1. Unplug machine, open magnetic switch cover,
turn amperage dial on Thermal Protection Circuit
Breaker to a higher amperage setting.
2. Inspect connections on motor for loose or shorted
terminals or worn insulation.
3. Correct the low voltage condition with a qualified
electrician.
4. Install correct fuses or circuit breakers.
Loud, repetitious noise
coming from machine. 1. Pulley setscrews or keys are
missing or loose.
2. Motor fan is hitting the cover.
1. Inspect keys and setscrews. Replace or tighten if
necessary.
2. Tighten fan or shim cover, or replace items.
Machine slows when
operating. 1. Applying too much pressure to
workpiece.
2. Undersized circuit or using
extension cord.
3. Run capacitor is at fault.
1. Sand with less pressure—let the movement of the
belt do the work.
2. Make sure circuit wires are proper gauge & don't
use extension cord!
3. Replace run capacitor.
Machine vibrates
excessively 1. Stand not stable on floor
2. Loose motor mounting.
3. Weak or broken tension spring.
4. Idler roller is too loose.
5. Broken/defective sanding belt.
1. Secure stand to floor, reposition to level surface, or
shim the stand.
2. Check/tighten motor mounts.
3. Replace spring.
4. Adjust idler roller.
5. Replace sanding belt.
Deep sanding grooves or
marks in workpiece. 1. Sanding belt grit too coarse for
the desired finish.
2. Workpiece is being sanded across
the grain.
3. Too much sanding force on
workpiece.
4. Workpiece held still against the
belt.
1. Use a finer grit sanding belt.
2. Sand with the grain.
3. Reduce pressure on workpiece while sanding.
4. Keep workpiece moving while sanding on the belt.
Grains easily rub off the
belt. 1. Sanding belt has been stored in an
incorrect environment.
2. Sanding belt has been folded or
smashed.
1. Store sanding belt away from extremely dry or hot
temperature.
2. Hang sanding belt or store unfolded and unstacked.
