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.
