Devices for Safe Handling
Pneumatic tools that are operated with a torque > 10 Nm,
must be equipped with an auxiliary handle or fastened in a
clamping fixture via the clamping area 4.
 If you want to operate the pneumatic tool in a suspen-
sion device or a clamping fixture, take care to fasten it
in the device/fixture first before connecting it to the air
supply. This measure prevents accidental starting of oper-
ation.
Make sure that the auxiliary handle or the clamping fixture
holds the pneumatic tool securely and firmly.
Do not overload the clamping area.
Suspension Device(see figure A)
With the utility clip 13, you can fasten the pneumatic tool to a
suspension device.

– Mount the utility clip 13 to the pneumatic tool, and allow it
to engage in the slots 14.
Depending on the pneumatic tool's centre of gravity, either
the front or rear slots can be used.

– Mount the utility clip 13 onto the clamping area 4.
 Regularly check the condition of the utility clip and the
hook of the suspension device.
Clamping Fixture
– The pneumatic tool can be mounted in a clamping fixture
over the mentioned clamping area 4. If possible, utilise the
entire clamping area. The smaller the clamping area, the
stronger the clamping forces act.
Auxiliary Handle
– Slide the auxiliary handle 10 onto the clamping area (col-
lar) 4.
The auxiliary handle 10 can be set to any position for a secure
and low-fatigue working posture.
– Turn the wing bolt for adjustment of the auxiliary handle in
anticlockwise direction and set the auxiliary handle 10 to
the required position. Then tighten the wing bolt again in
clockwise direction.
Exhaust-air Guidance
With exhaust-air guidance, the exhaust air can be diverted
through an exhaust-air hose away from your workplace, while
at the same time achieving optimal sound-proofing. Addition-
ally, your working conditions are improved, as your workplace
can no longer be contaminated though oil-containing air and
dispersed dust or chips.
Centralised Exhaust-air Guidance (see figure B)
– Loosen hose clamp 16 of supply-air hose 15, mount the
supply-air hose to hose fitting 7 and retighten the hose
clamp.
– Work the exhaust-air hose (centralised) 17, which con-
ducts the exhaust air away from your workplace, over the
Bosch Power Tools
supply-air hose 15. Then connect the pneumatic tool to
the air supply (see "Connecting the Air Supply", page 23)
and work the exhaust-air hose (centralised) 17 over the
mounted supply-air hose onto the end of the pneumatic
tool.
Decentralised Exhaust-air Guidance (see figure C)
– Unscrew the silencer at air outlet 8 and replace it with a
hose fitting 7.
– Loosen hose clamp 16 of the exhaust-air hose 18, mount
the exhaust-air hose to hose fitting 7 and retighten the
hose clamp.
Connecting the Air Supply
 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.
– Before connecting to the air supply, operate the On/Off
switch 9 (0 607 453 4..) several times or simultaneously
the On/Off switches 11 and 12 (0 607 461 4..).
Connecting the Air Supply to the Pneumatic Tool
(see figure D)
– Screw hose fitting 7 into the connection socket at air inlet
6.
To avoid damage to interior valve components of the pneu-
matic tool when screwing hose fitting 7 in or out, it is rec-
ommended to counter-hold the projecting connection
socket of air intake 6 with an open-end wrench (size
22 mm).
– Loosen hose clamp 16 of supply-air hose 15, mount the
supply-air hose to hose fitting 7 and retighten the hose
clamp.
Note: Always mount the supply-air hose to the pneumatic tool
first, then to the maintenance unit.
Changing the Tool (see figure E)
– Pull the sleeve 19 of the quick-change chuck to the front
and hold.
– Place the application tool into the tool holder 1 and release
the sleeve 19.
