# Changing the Tool

The ONECHUCK drill chuck enables you to use SDS plus application tools, cylindrical and hexagonal application tools easily and conveniently without needing to use additional tools or change the drill chuck.

The dust protection cap (3) largely prevents the penetration of drilling dust into the tool holder during operation. When inserting the tool, make sure that the dust protection cap (3) does not become damaged.

- Replace a damaged dust protection cap immediately. It is recommended that you have use an after-sales service for this.

## Changing the Tool (SDS plus)

### Inserting the SDS plus Application Tool (see figures B1−B2)

- Hold the rear sleeve (5) of the drill chuck with one hand. Use your other hand to fully open the tool holder by turning the front sleeve (4).
- Clean and lightly grease the shank of the SDS plus application tool.
- Insert the SDS plus application tool into the tool holder while turning it until it locks automatically.
- Check that it is locked by pulling on the tool.

As a requirement of the system, the SDS plus application tool can move freely. This causes a certain radial run-out at no-load, which has no effect on the accuracy of the drill hole, as the drill bit centres itself upon drilling.

### Removing the SDS plus Application Tool (see figure B3)

- Push the rear sleeve (5) back and remove the SDS plus application tool.

## Changing the Tool (cylindrical/hexagonal shank)

### Inserting the Application Tool (see figure C1)

Note: Application tools that do not have SDS plus must not be used for hammer drilling. Tools without SDS plus and their drill chucks are damaged by hammer drilling.

Note: Only use tools with a cylindrical or hexagonal shank in the drilling operating mode.

- Do not close the drill chuck by switching on the power tool. The application tool can be ejected. This poses a risk of injury.

Note: Only use application tools with a cylindrical or hexagonal shank with a shank diameter of 6 to 10 mm.

- Turn the impact/mode selector switch (13) to the "drilling" position.

- Hold the rear sleeve (5) of the drill chuck with one hand. Use your other hand to open the tool holder by turning the front sleeve (4) until the application tool can be inserted.
- Insert the cylindrical or hexagonal application tool into the drill chuck.
- Hold the rear sleeve (5) in place with one hand and, with the other hand, turn the front sleeve (4) firmly in the direction of the arrow until you hear a clear clicking sound.
- Check that it is seated securely by pulling on the tool.

Only insert the application tool if the power tool is switched off.

### Removing the Application Tool (see figure C2)

- Hold the rear sleeve (5) of the drill chuck with one hand. Use your other hand to open the tool holder by turning the front sleeve (4) in the direction of the arrow until the application tool can be removed.
- Remove the application tool.

- Do not open the drill chuck by switching on the power tool. The application tool can be ejected. This poses a risk of injury.
