Maintenance and Cleaning

Before performing any work on the unit itself,
disconnect the air supply.
Keep the unit 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 . . . . . .

Wash out the gearbox with petroleum after the first
approx. 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
