tripped circuit).
Short circuit in motor or loose
connections.
Inspect connections on motor for loose
or shorted terminals or worn insulation.
(Send for Servicing.)
Low voltage.

Install correct fuses or circuit breakers
or plug tool into an appropriate circuit,
matched to an appropriate fuse or
breaker.
Motor overload.
Reduce the load on the motor.

when operating.
Feed rate too great.
Reduce the rate at which the
workpiece is fed into the working area
of the tool (grinding wheel).
Lines on surface
of workpiece.
Impurity on surface of wheel.
Clean or replace the buffing wheel.
Workpiece is not being held tightly.
Use a holding device to more firmly
