Connecting the Air Supply (see figure E)
 Ensure that the air pressure is not lower than 6.3 bar
(91 psi) because the pneumatic tool is designed for
this operating pressure.
For maximum performance, the values for the inner hose di-
ameter as well as the connection threads must be adhered to
as listed in the "Technical Data" Table. To maintain the full
performance, only use hoses with a maximum length of 4 m.
The compressed air supplied should be free of foreign materi-
al and moisture to protect the tool from damage, contamina-
tion, and the formation of rust.
Note: The use of a compressed-air maintenance unit is neces-
sary. This ensures proper function of the pneumatic tools.
Observe the operating instructions of the maintenance unit.
All fittings, connecting lines and hoses must be dimensioned
for the pressure and the required air volume.
Avoid restrictions in the air supply, e.g., from pinching, kink-
ing, or stretching!
When in doubt, check the pressure at the air inlet with a pres-
sure gauge with the pneumatic tool switched on.
Connecting the Air Supply to the Pneumatic Tool
– Screw hose fitting 5 into the connection socket at air inlet 20.
To avoid damage to interior valve components of the pneu-
matic tool when screwing hose fitting 5 in or out, it is recom-
mended to counter-hold the projecting connection socket
of air intake 20 with an open-end wrench (size 22 mm).
– Loosen hose clamp 11 of supply-air hose 21, mount the
supply-air hose to hose fitting 5 and retighten the hose
clamp.
Note: Always mount the supply-air hose to the pneumatic tool
first, then to the maintenance unit.
Mounting the Drill Chuck (see figure F)
– Hold drill spindle 1 in place by the spanner flats 6 using a
fitting open-end spanner and screw the key-type drill
chuck 23 or the keyless chuck 24 onto the drill spindle.
 The drill chuck must be tightened with a tightening
torque of approx. 20–25 Nm.
Changing the Key Type Drill Chuck
– Hold the drill spindle 1 in place by the spanner flats using a
fitting open-end spanner.
– Insert the chuck key 25 into one of the three holes of the
key-type drill chuck 23 and loosen the drill chuck by turn-
ing in anticlockwise direction.
Note: Loosen a tight-seated drill chuck by counter-holding
with an Allen key clamped in the tool holder 26.
Changing the Keyless Chuck
– Place the pneumatic tool on a stable surface (e. g. a work-
bench).
– Hold drill spindle 1 in place by the spanner flats 6 using a
fitting open-end spanner and loosen the drill chuck 24
from the drill spindle by turning in anticlockwise direction.
Note: Loosen a tight-seated drill chuck by counter-holding
with an Allen key clamped in the tool holder 26.

Changing the Tool (see figure G)
Key Type Drill Chuck
– Open the key type drill chuck 23 by turning until the tool
can be inserted. Insert the tool.
– Insert the chuck key 25 into the corresponding holes of the
key type drill chuck 23 and clamp the tool uniformly.
Removing:
– Turn the sleeve of the key type drill chuck 23 with the drill
chuck key in anticlockwise direction until the drilling tool
can be removed.
Keyless Chuck
– Hold the rear sleeve 27 of the keyless chuck 24 and turn
the front sleeve 28 in anticlockwise direction until until the
tool can be inserted. Insert the tool.
– Hold the rear sleeve 27 of the keyless chuck 24 and firmly
turn the front sleeve 28 in clockwise direction until a
"click" can be heard. This automatically locks the drill
chuck.
Removing:
– The locking is released again to remove the tool when the
front sleeve 28 is turned in the opposite direction.
Operation

Starting Operation

The pneumatic tool works optimally at a working pressure of
6.3 bar (91 psi), measured at the air inlet when the pneumat-
ic tool is switched on.
Starting and Stopping (see figure H)
Note: When the pneumatic tool does not start, for example af-
ter a longer rest period, disconnect the air supply, and turn
the motor by the tool holder 26 several times through. This re-
moves the adhesive forces.
To save energy, only switch the pneumatic tool on when you
are using it.
