Check air pressure:
■ The product is designed for a working pressure (e) of 6-6,3 bar = 600-630 kPa = 87-90 psig.
■ The air pressure at the tool inlet with the product running must not exceed the maximum operating
pressure 6.3.
■ Blow out the hose before connecting it.

Preparations before using the die grinder
Correct function of die grinder
WARNING Overspeed can result in serious injury or death
►
The maximum permissible speed as marked on the machine must not be exceeded
Testing of the die grinder should only be carried out by professional technicians. The technicians must be
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
■ Use a pressure regulator to avoid excessive air pressure which may cause overspeed
■ Connections and air hose must be in good condition
Mounted wheel and carbide burr
WARNING Air under pressure can cause serious injury
►
Always shut off air supply, drain hose of air pressure and disconnect tool from air supply when not
in use, before making any adjustments to the machine, e.g. changing accessories, or when mak-
ing repairs
WARNING Wrong insert tool can burst and cause serious injury or death
►
Use insert tool with max operating speed higher or equal to the airgrinder speed
►
Do not use other insert tool than specified by the manufacturer (no cutting off wheels or router
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
