5 OPERATING INSTRUCTIONS
Disconnect the air hose from the air supply be-
fore making any adjustments, changing acces-
sories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool acciden-
tally.
The angle grinders are supplied with protective guard,
inner flange, and outer flange nut as well as adjusting
tools (pin spanner wrench and open end wrench), but
not with accessories.
Use the accessory only for the recommended
applications – e.g., never use a cut-off wheel for wire
brushing.
The rated speed of the accessory
must be at least equal to the maxi-
mum speed marked on the air tool.
Accessories running faster than their
rated speed can fly apart.
Abrasive, Cut-Off, and Wire Brush
Wheels
Observe the dimensions of the abrasive wheels 10;
e.g., 125 x 6 x 22.2 mm corresponds to an outer di-
ameter of 125 mm, a thickness of 6 mm, and an inner
hole diameter of 22.2 mm. The inner hole diameter
must match the inner flange 11. Do not use a reducing
piece or adapter.

(22 mm) to apply a counterforce at the protruding con-
nector of the air inlet 19 when screwing/unscrewing
the hose nipple 1.
Loosen the hose clamps 20 of the air inlet hose 23
with a maximum length of 4 m and attach the air inlet
hose over the hose nipple 1 by firmly tightening the
hose clamp.
Always connect the air inlet hose 23 first to the
tool, then to the maintenance unit.
Slip the air inlet hose 23 over the coupling nipple 24
and attach the air inlet hose by firmly tightening the
hose clamp 20.
Screw a quick hose connector 25 into the air outlet of
the maintenance unit 26. Quick hose connectors
make possible a quick connection and, when uncou-
pled, they shut off the air supply automatically.
Take care that you do not start the tool accidentally
when you insert the coupling nipple 24 into the coupler
25.
