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 dir-
ectives.
• The free speed of the machine shall be checked
every day and whenever the machine has been
serviced. 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 condi-
tion

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
making repairs
T
WARNING Wrong insert tool can burst and
cause serious injury or death
►
Use insert tool with max operating speed higher

Do not use other insert tool than specified by the
manufacturer (no cutting off wheels or router bits).
See Section
Design and function
.
• Use only recommended sizes and types of abras-
ives
• 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 cor-
rect 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 posi-
tion 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
