Grinding Wheels 
The JET Series bench grinders come equipped 
with general purpose grinding wheels. Wheels 
vary according to types of abrasive, hardness, 
grit size, and structure. JET carries a full line of 
abrasive grinding, carbide grinding, tool 
sharpening, and wire wheels. Contact your local 
distributor for the proper grinding wheel or wire 
wheel brush for your application. 
Wire Wheel Brushes 
Wire brushing provides a fast way to remove 
rust scale, burrs, and point from metal. Use 
coarse wire brushes for hard cleaning jobs. Use 
fine wire brushes for polishing and finish work. 
When the brush tips become dull, reverse the 
brush on the grinder. 
Cleaning 
  Metal shavings may still be 
hot from recent grinding operations. Make 
sure shavings and debris are cold before 
cleaning the grinder. 
Brush all shavings from the motor housing, tool 
rests, and wheel guards. Check grinding wheels 
for cracks and chips. 
Replace if damaged. 
  Avoid the use of the 
following cleaning chemicals or solvents: 
gasoline, carbon tetrachloride, chlorinated 
solvents, ammonia and household 
detergents containing ammonia. 
 
Lubrication 
All motor bearings are permanently lubricated at 
the factory and require no additional lubrication.
