PROBLEM / PROBABLE CAUSE
REMEDY
1.Grinder not plugged in.
2.Low Voltage.
3.Open circuit in motor or loose
connections.
4.Blown fuse or breaker.
5.Cord damaged.
1.Plug in the grinder.
2.Check power source for proper voltage.
3.Inspect all lead connections on motor for loose or
open connections.
(Send for Servicing)
4.Replace fuse or reset circuit breaker.
5.Have cord replaced by an authorized service center.
1.Motor overloaded.
2.Extension cord too long and of
insufficient gauge (weight).
1.Reduce load on motor.
2.Utilize an extension cord of appropriate gauge and
length or plug tool directly into outlet.
1.Feed rate too great.
1.Reduce the rate at which the workpiece is fed into
the working area of the tool (grinding wheel).
1.Impurity on surface of wheel.
2.Workpiece not being held tightly.
1.Dress the grinding wheel.
2.Use a holding device to more firmly retain the work-
piece.
1.Machine vibrating.
2.Workpiece not being held firmly.
3.Wheel face uneven.
4.Wheel is too hard..
1.Ensure machine is securely mounted on a solid
surface.
2.Use a holding device to firmly retain the workpiece.
3.Dress the grinding wheel.
4.Use softer wheel, or reduce the feed rate.
1.Short circuit in motor or loose
connections.
2.Low voltage.
3.Incorrect fuses or circuit
breakers in power line.
4.Motor overload.
1.Inspect connections on motor for loose or shorted
terminals or worn insulation. (Send for Servicing)
2.Correct low voltage conditions (for example:
improper extension cord length and/or gauge).
3.Install correct fuses or circuit breakers or plug tool
into an appropriate circuit, matched to an appropriate
fuse or breaker.
4.Reduce the load on the motor.
1.Improper type of grinding wheel.
2.Improper feed rate.
3.Coolant required.
1.Try wheels with softer bond or coarser grit.
2.Slow down the rate at which the workpiece is fed
into the wheel.
3.Introduce coolant.
1.Feed rate is too aggressive.
2.Wheel is soft.
3.Wheel diameter too small.
4.Bad wheel dressing.
5.Defective wheel bonding.
1.Decrease feed rate of workpiece into grinding wheel.
2.Select a grinding wheel with a harder bond of
material.
3.Replace wheel.
4.Dress the wheel.
5.DO NOT USE – return wheel to point of purchase.
1.Wheel is too hard.
2.Feed rate is too slow.
3.Bad wheel dressing.
4.Coolant required.
1.Select a grinding wheel with a softer bond of
material.
2.Increase the feed rate of the workpiece into the
grinding
3.Dress the wheel.
4.Introduce coolant.
