Inserting the Key Type Drill Chuck (see figure D)

Clean the shank end of the adapter shank and apply a light coat of grease.

Insert the key type drill chuck with the adapter shank into the tool holder with a turning motion until it automatically locks.

Check the locking effect by pulling the key type drill chuck.

Removing the Key Type Drill Chuck

Push the locking sleeve 3 toward the rear and pull out the key type drill chuck 13.

The dust protection cap 2 largely prevents the entry of drilling dust into the tool holder during operation. When inserting the tool, take care that the dust protection cap 2 is not damaged.

fA damaged dust protection cap should be changed immediately. We recommend hav- ing this carried out by an after-sales service.

Inserting SDS-plus Drilling Tools (see figure E)

The SDS-plus drill chuck allows for simple and convenient changing of drilling tools without the use of additional tools.

Clean and lightly grease the shank end of the tool.

Insert the tool in a twisting manner into the tool holder until it latches itself.

Check the latching by pulling the tool.

As a requirement of the system, the SDS-plus drilling tool can move freely. This causes a cer- tain 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 SDS-plus Drilling Tools (see figure F)

Push back the locking sleeve 3 and remove the tool.

Inserting Drilling Tools without SDS-plus

Note: Do not use tools without SDS-plus for ham- mer drilling! Tools without SDS-plus and their drill chucks are damaged by hammer drilling.

Insert a key type drill chuck 13 (see “Changing the Key Type Drill Chuck”, page 19).

Open the key type drill chuck 13 by turning until the tool can be inserted. Insert the tool.

Insert the chuck key into the corresponding holes of the key type drill chuck 13 and clamp the tool uniformly.

Set the selector switch 7 to the “Drilling” sym- bol.

Removing Drilling Tools without SDS-plus

Turn the sleeve of the key type drill chuck 13 with the drill chuck key in anticlockwise direction until the drilling tool can be removed.

Dust Extraction with the Dust Extraction Attachment (Accessory)

Mounting the Dust Extraction Attachment (see figure G)

For dust extraction, the dust extraction attach- ment (accessory) is required. When drilling, the dust extraction attachment retracts so that the attachment head is always close to the surface at the drill hole.

Press the button for depth stop adjustment 8 and remove the depth stop 11. Press button 8 again and insert the dust extraction attachment into the auxiliary handle 10 from the front.

Connect an extraction hose (diameter 19 mm, accessory) to the extraction sleeve 15 of the dust extraction attachment.

The vacuum cleaner must be suitable for the material being worked.

When vacuuming dry dust that is especially detri- mental to health or carcinogenic, use a special vacuum cleaner.
