Troubleshooting
Fault Probable cause Suggested remedy
Motor will not run 1. Motor is defective
2. Voltage is too low
3. Switch is defective
4. Branch circuit fuse is blown or the circuit
breaker is tripped
5. Branch is shut down for service
6. Open circuit in the wiring
1. Replace the motor.
2. Check the power supply for the proper
voltage.
3. Replace the switch.
4. Determine the reason for the blown
fuse or tripped circuit breaker -- then
replace the fuse or reset the breaker.
5. 5. Check all personnel and machines
on the branch to be certain someone
has not shut down the branch for
service. DO NOT replace the fuse or
reset the breaker unless you are
certain no personnel are working on
the machines, wires or con trols in the
circuit.
6. 6. Inspect all the wire connections for
loose or open connections.
Motor stalls easily 1. Low voltage.
2. Fuse is blown (three phase motors
only.)
3. Improper wiring.
1. Check for proper voltage at the motor
-- correct as necessary.
2. Replace the blown fuse.
3. Check for proper connections.
Abrasive belt or disc slows
down although motor keeps
running at working speed
1. Belt is slipping 1. Replace the belt.
Poor tracking 1. Tracking is out of adjustment.
2. Too much belt tension.
3. Not enough belt tension.
4. Belt is jointed improperly.
5. Lack of crown on the drive roller.
6. Worn bearings.
1. Adjust the belt tracking.
2. Loosen the tension until the belt is just
taut.
3. Tighten the tension until the belt is
more taut.
4. Check the belt for an irregular seam
or shape.
5. Remove the belt and put a straight
edge along the drive roller. There
should be a slight crown (high spot
toward the middle of the roller.) If the
crown has worn away, replace the
roller.
6. Check all the bearings for excessive
heat or loose shafts. Replace if
necessary.
Unsteady belt 1. Slack in the abrasive belt. 1. Adjust the belt tension.
Short belt life 1. Excessive pressure applied while
grinding.
2. Working on only one side of the belt
or only in one area of the disc.
3. Incorrect abrasive material or grit size.
1. Allow the belt to do the cutting.
Excessive pressure only dulls the grit
and removes it from the cloth.
2. Use all the surface areas of the
abrasive cloth.
3. Check with your abrasives supplier for
rec ommendations on the type and coarse
ness of the abrasive required for the
workpieces you are sanding or grinding.
CAUTION: For all of the electrical faults and corrections in the above table we recommends the use of a qualified and
licensed electrician for all circuit tracing, diagnosis and repair.
