CHANGING THE GRINDING WHEELS
1.
Switch the bench grinder “OFF” and disconnect from the power supply.
2.
Remove the screws which secure the grinding wheel side covers then take off covers.
3.
Either, hold the opposite wheel firmly and remove the nut and flange, or place a wedge
between the grinding wheel and the wheel guard, then remove the nut and flange.
NOTE: the left hand grinding wheel nut has a left thread.
4.
When fitting a new grinding wheel always check that the stated max. grinding wheel RPM
exceeds the RPM of the bench grinder. Also check the grinding wheel for damage such as
flaws or cracks, then if the wheel appears satisfactory fit the new wheel to the grinder.
5.
Remove the old wheel and replace it with the new one.
6.
Place the flange on the spindle and tighten the spindle nut just enough to hold the wheel
firmly.
Do not over tighten the nut as the wheel may become damaged.
Repeat the above to
replace the opposite wheel.
7.
Re-assemble the side covers.
8.
Stand to one side of the grinder and switch “ON”. Let the grinder operate at full speed for
approximately one minute so that any undetected cracks or flaws in the wheel will become
apparent.
