Assembly
Connecting the Air Supply (see figure A)
Pay attention that the air pressure is not less than
6.3 bar (91 psi), as 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 4 into the connection socket at air inlet
3.
To avoid damage to interior valve components of the pneu-
matic tool when screwing hose fitting 4 in or out, it is rec-
ommended to counter-hold the projecting connection
socket of air intake 3 with an open-end wrench (size
22 mm).
– Loosen hose clamp 5 of supply-air hose 6, mount the sup-
ply-air hose to hose fitting 4 and retighten the hose clamp.
– Work the other end of the supply-air hose 6 over coupling
nipple 7 and fasten the supply-air hose by retightening the
other hose clamp 5.
– Screw a quick-action safety coupling 8 into the air outlet of
the maintenance unit 9.
Quick-action safety couplings enable swift connecting and
automatically shut off the air supply upon disconnecting
(uncoupling).
Note: Always mount the supply-air hose to the pneumatic tool
first, then to the maintenance unit.
– To connect the supply-air hose to the maintenance unit, in-
sert coupling nipple 7 into quick-action safety coupling 8.

Mounting application tools
Inserting a Chisel (0 607 560 500) (see figure B)
– Screw retaining spring 11 to the stop onto tool holder 10.
– Bend hook clip 12 of retaining spring 11 open and insert a
chisel until the shoulder of the chisel is positioned behind
the hook clip.
– Release the hook clip 12.
This secures the chisel against falling out.
Changing Needles (0 607 560 502) (see figure C)
– Loosen the pan head screws 15.
– Pull guide sleeve 14 completely away from the needles.
This relieves the spring pressure on the apertured disc 17.
– Remove the apertured disc 17 together with the needles
from the needle holder 16.
– Push the needles out toward the rear and replace them.
– Assemble/mount all components again, tighten all pan
head screws and lock them with their lock nuts.
Operation
Starting Operation
The pneumatic tool operates optimally at a nominal pressure
of 6,3 bar (91 psi), measured at the air inlet of the actuated
pneumatic tool.
Starting and Stopping
– To switch on the pneumatic tool, press the On/Off switch
1 and keep it pressed during the working procedure.
– To switch off the pneumatic tool, release the On/Off
switch 1.
Working Advice
Sudden loads cause a sharp drop in speed or a complete stop,
yet do not cause damage to the motor.
When working, prevent idle running of the pneumatic tool.
Always press the chisel or needles firmly against the work-
piece.
Readjusting Needles (0 607 560 502)
– Loosen the pan head screws 15.
– Slide guide sleeve 14 a little further onto needle holder 16.
– Tighten all pan head screws and lock them with their lock
nuts.
Maintenance and Service
Maintenance and Cleaning
If the pneumatic tool should fail despite the care taken in man-
ufacture and testing, repair should be carried out by an au-
thorised customer services agent for Bosch power tools.
In all correspondence and spare parts orders, please always
include the 10-digit article number given on the type plate of
the pneumatic tool.
Have maintenance and repair work carried out only
through qualified persons. This will ensure that the safe-
ty of the pneumatic tool is maintained.
