Insert the adjustment tool 12 in the cut-out of the ad-
justment disk 13 and turn to the left until the tension
of the spring 22 contained therein is completely re-
leased and it can be removed.
Insert a new spring and reassemble the clutch in the
reverse order.
Extraction of the Exhaust Air
Slide the exhaust air hose 6
hose 7. Mount the air supply hose 7 onto the hose
connection piece 5 and attach the exhaust air
hose 6 to the housing.
Or remove hose connection piece 5 and attach the
exhaust air set (separate) to the connection piece on
the machine. Screw the hose connection piece 5
onto the connection piece. The silencer on the ex-
haust air set (separate) can be removed and an air
hose to exhaust equipment mounted instead.
Advantages:
– Noise reduction
– No contamination of the working area by stirred
up dust
– Exhaust air led away.

Maintenance and Cleaning

Before performing any work on the machine it-
self, disconnect the air supply.
Keep the machine and the tool holder clean at all
times.
If the machine should happen to fail despite the care
taken in manufacture and testing, repair should be
carried out by an authorised customer services agent
for Bosch pneumatic tools.
For all correspondence and spare parts orders, always
include the 10-digit order number of the machine.
Lubrication
Lubricant:
Special gearbox grease 225 ml
3 605 430 009
Molycote grease
SAE 10 / SAE 20 motor oil
Clean regularly the screen on the air inlet of the ma-
chine. For this purpose, unscrew the hose connection
piece 5 and remove dust and dirt particles from the
screen. Then firmly remount the hose connection
piece.
Wash out the gearbox with petroleum after the first ap-
prox. 150 hours of operation and then every 300 hours
of operation and lubricate with special gearbox
grease.
Lubricate the moving parts of the clutch after approx.
each 100 000 screwing operations with a few drops of
SAE 10 / SAE 20 motor oil. Grease the sliding and
rolling parts with Molycote grease. Check the clutch
adjustment afterwards.

flange b over the outer ring of the ball bearing f.
The rotor must rotate freely!

Set the longitudinal play between the bearing
flange g and rotor h to 0.02 ± 0.01 mm.
If the rotor is not easy-running, hold the bearing
flange g and eliminate the binding with a light
blow from a copper hammer on the pinion.
Self-made aids for vane replacement:
w Pressure piece – dia. 6.5 mm x approx. 20 mm
x Pressure piece – dia. 18 mm x approx. 20 mm
y Support bushing – dia. 8.5 mm x dia. 18 mm x
approx. 20 mm
z Pressure piece – dia. 7.5 mm x dia. 10 mm x
approx. 20 mm
Any Bosch customer service centre can perform this
work quickly and reliably.
Dispose of lubricants and cleaning agents in an
environmentally correct manner. Observe legal
