# Maintenance and Cleaning

- Before carrying out any work on the power tool (e.g. maintenance, tool change etc.), remove the battery from the power tool. There is risk of injury from unintentionally pressing the on/off switch.

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

Clean and lubricate the punch (8) and die (9) every three operating hours.

Change the punch and die in good time when worn. Only sharp tools produce a good cutting quality and make the power tool last longer.

The punch (8) and the die (9) may not be resharpened.

## Changing the die

Unscrew the knurled screw (11) from the die holder (7). Take out the die (9).

If necessary, clean the die holder (7). Put a new, well greased die (9) into the die holder. Pay attention to the alignment of the flat side.

Screw back on the knurled screw (11) with the rubber ring (10) attached. Use a hex key to tighten the screw against the resistance of the rubber ring (3–4 Nm).

## Changing the punch

Loosen the die holder screw (4) and pull the die holder (7) completely out of the housing.

Slide the punch (8) sideways out of the mounting and pull it out in a downward motion.

Put a new, well greased punch (8) in the groove of the mounting and centre it.

Push the die holder (7) carefully over the punch and back into the housing. Turn the die holder into one of the three possible positions depending on the cutting direction required. Firmly tighten the die holder screw (4).
