or  circuit  breakers  tripping 
or blowing. 

1.  Short circuit in line, cord or 

plug. 

2.  Short circuit in motor or loose 

connections. 

3.  Incorrect fuses or circuit 

breakers in power line. 

1.  Inspect cord or plug for damaged 

insulation and shorted wires. 

2.  Inspect all connections on motor 

for loose or shorted terminals 
and/or worn insulation. 

3.  Install correct fuses or circuit 

breakers or switch tool to an 
appropriately sized circuit. 

Motor overheats. 

4.  Motor overloaded. 
5.  Extension cord too long and of 

insufficient gauge (weight). 

4.  Reduce load on motor. 
5.  Utilize an extension cord of 

appropriate gauge and length or 
plug tool directly into outlet. 

Motor  stalls  (resulting  in 
blown  fuses  or  tripped 
circuit). 

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. 

Machine 

slows 

when 

operating. 

1.  Feed rate too great. 

1.  Reduce the rate at which the 

workpiece is fed into the working 
area of the tool (grinding wheel). 

Wavy  condition  on  surface 
of workpiece. 

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.

on 

surface 

of 

workpiece. 

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 workpiece.

the workpiece. 

3.  Improper type of grinding 

wheel. 

4.  Improper feed rate. 
5.  Coolant required. 

3.  Try wheels with softer bond or 

coarser grit. 

4.  Slow down the rate at which the 

workpiece is fed into the wheel. 

5.  Add coolant. 

Wheel  dulls  quickly,  grit 
falls off. 

6.  Feed rate is too aggressive. 
7.  Wheel is soft. 
8.  Wheel diameter too small. 
9.  Bad wheel dressing. 
10.  Defective wheel bonding. 

6.  Decrease feed rate of workpiece 

into grinding wheel. 

7.  Select a grinding wheel with a 

harder bond of material. 

8.  Replace wheel. 
9.  Dress the wheel. 
10.  DO NOT USE – return wheel to 

point of purchase. 

Wheel clogs and workpiece 
shows burn marks. 

11.  Wheel is too hard. 
12.  Feed rate is too slow. 
13.  Bad wheel dressing. 
14.  Coolant required. 

11.  Select a grinding wheel with a 

softer bond of material. 

12.  Increase the feed rate of the 

workpiece into the grinding 
wheel. 

13.  Dress the wheel. 
14.  Add coolant.
