Maintenance and Service
Maintenance and Cleaning
Before any work on the machine (e.g., main-
tenance, tool change, etc.) as well as during
transport and storage, set the rotational di-
rection switch to the centre position. Unin-
tentional actuation of the On/Off switch can
lead to injuries.
For safe and proper working, always keep
the machine and ventilation slots clean.
When the battery is no longer operative, please
refer to an authorised after-sales service agent
for Bosch power tools.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts order,
please always include the 10-digit article
number given on the type plate of the machine.
Power Tool Lubrication
Lubricants:
Special gearbox grease (225 ml)
Article number 3 605 430 009
Molycote grease
SAE 10/SAE 20 engine oil
Clean the gearbox after the first 150 running
hours using a mild solvent. Follow the solvent
manufacturers directions for use and disposal.
Lubricate the gearbox using Bosch gearbox
lube. Repeat the lubrication procedure every
300 hours after the initial gearbox service.
Oil the moving parts of the shut-off clutch after
100000 screwing operations with a few drops of
SAE 10/SAE 20 motor oil. Lubricate the sliding
and rolling parts with Molycote grease. At this
time, inspect the clutch for wear in order to en-
sure that the repeatability and accuracy have
not been affected. Afterwards, the torque of the
clutch must be readjusted.
Have maintenance and repair work per-
formed only by qualified specialists. In this
manner, it can be ensured that the safety of
the power tool is maintained.
