Maintenance and Cleaning

Pull the plug out of the socket before carrying out any work on the power tool.

To ensure safe and efficient operation, always keep the power tool and the ventilation slots clean.

In order to avoid safety hazards, if the power supply cord needs to be replaced, this must be done by Bosch or by an after-sales service centre that is authorised to repair Bosch power tools.

Keep the parking rest (19) clear and clean it regularly.

When the carbon brushes are worn out, the power tool switches itself off. The power tool must be sent to the after-sales service for maintenance; see the "After-Sales Service and Application Service" section for addresses.

Changing the Drive Belt (see figures L–M)

Unscrew the screw (6) completely and take off the belt cover (7). Remove the worn drive belt (28).

Before fitting a new drive belt (28), clean the two belt wheels (29) and (30).

First place the new drive belt (28) onto the small drive wheel (30), and then press the drive belt (28) onto the large drive belt (29), turning it by hand.

Make sure that the drive belt (28) runs exactly in the lengthways grooves in the drive wheels (29) and (30).

Put the belt cover (7) on and tighten the screw (6).
