authorized to test this type of tool and to operate a pneumatic system in accordance with national direc-

tives.

■

The free speed of the machine shall be checked every day and whenever the machine has been ser-

viced. This check should be carried out with the grinding equipment detached

■

bits).

■

Use only recommended sizes and types of abrasives

■

Do not use mounting wheels that are chipped or cracked, or may have been dropped

■

Correct mounting is necessary to prevent injury from broken mounted wheels

■

Ensure the shaft diameter of the accessory is correct for the size of collet

■

Do not mix mm shanks with inch collets and vice versa

■

Observe a min of 10 mm axial grip of the shank

■

When fitting mounted wheels or burrs, reduce the overhang by pushing the shank all the way into the

collet (Check also the recommendations given by the tool manufacturer)

■

Observe that increased overhang of shank reduces permissible speed

■

Before starting the machine, check that the collet is properly tightened

Test run every new mounted wheel in a safe position for 30 seconds. Be sure to use a barrier (such

as under a heavy work table) to stop any possible broken wheel parts. Stop immediately if vibration is

excessive
