Assembly

f Before any work on the machine itself, pull the mains

plug.

Auxiliary Handle

f Operate your machine only with the auxiliary handle 9.

The auxiliary handle 9 can be set to any position for a secure

and low-fatigue working posture.

– Turn the bottom part of the auxiliary handle 9 in counter-

clockwise direction and swivel the auxiliary handle 9 to the

desired position. Then retighten the bottom part of the

auxiliary handle 9 by turning in clockwise direction.

Changing the Tool

With the SDS-max tool holder, simpler and easier tool chang-

ing is possible without additional aids.

The dust protection cap 1 largely prevents the entry of drilling

dust into the tool holder during operation. When inserting the

tool, take care that the dust protection cap 1 is not damaged.

f A damaged dust protection cap should be changed im-

mediately. We recommend having this carried out by

an after-sales service.

Inserting (see figure A)

– 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.

Removing (see figure B)

– Push back the locking sleeve 2 and remove the tool.

Dust/Chip Extraction

Dusts from materials such as lead-containing coatings, some

wood types, minerals and metal can be harmful to one’s

health. Touching or breathing-in the dusts can cause allergic

reactions and/or lead to respiratory infections of the user or

bystanders.

Certain dusts, such as oak or beech dust, are considered as

carcinogenic, especially in connection with wood-treatment

additives (chromate, wood preservative). Materials contain-

ing asbestos may only be worked by specialists.

– Provide for good ventilation of the working place.

– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the mate-

rials to be worked.

Operation

Starting Operation

f Observe correct mains voltage! The voltage of the pow-

er source must agree with the voltage specified on the

nameplate of the machine. Power tools marked with

230 V can also be operated with 220 V.

Setting the Operating Mode

The operating mode of the power tool is selected with the

mode selector switch 4.

Note: Change the operating mode only when the machine is

switched off! Otherwise, the machine can be damaged.

– Press and hold the unlocking button 3 and turn the mode

selector switch 4 to the required position.

Switching On and Off

–To start the machine, press the On/Off switch 5 and keep

it pressed.

– To switch off the machine, release the On/Off switch 5.

For low temperatures, the machine reaches the full ham-

mer/impact capacity only after a certain time.

This start-up time can be shortened by striking the inserted

tool insert against the floor one time.

Setting the Speed/Impact Rate

The electronic control enables stepless speed and impact

preselection in accordance with the material to be worked.

The constant electronic control keeps the preselected speed

and impact rate nearly constant between no-load and load

conditions.

The maximum hammering capacity is achieved when the

thumbwheel 7 is set to position “6”. For lower speed settings,

the hammering capacity is lower due to technical reasons.

– Select the speed with the thumbwheel 7 according to the

material.

The data in the following table are recommended values.
