increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Auxiliary handle (see figure D)
Do not operate your power tool without the auxiliary
u
handle (9).
You can swivel the auxiliary handle (9) to any angle for a safe
work posture that minimises fatigue.
– Loosen the knurled nut (10), rotate the auxiliary handle
(9) around the axis of the tool to the required position
and retighten the knurled nut (10).
The auxiliary handle (9) can be refitted in a different posi-
tion.
– To do this, completely unscrew the knurled nut (10) and
then pull the hexagon bolt upwards and out.
– Pull off the auxiliary handle (9) to the side and rotate the
remaining clamping element by 180°.
– Fit the auxiliary handle (9) by following the steps in re-
verse order.
Changing the Tool
With the SDS-max tool holder, you can change the applica-
tion tool simply and easily without additional aids.
The dust protection cap (1) largely prevents the penetration
of drilling dust into the tool holder during operation. When
inserting the tool, make sure that the dust protection cap (1)
does not become damaged.
Replace a damaged dust protection cap immediately.
u
It is recommended that you have use an after-sales
service for this.
Inserting the application tool (see figure A)
– Clean and lightly grease the insertion end of the applica-
tion tool.
– Insert the application tool into the tool holder while turn-
ing it until it locks automatically.
– Check the latching by pulling the tool.
Removing the application tool (see figure B)
– Push the locking sleeve (2) back and remove the applica-
tion tool.

Dust/Chip Extraction

Dust 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 dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
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 ma-
terials to be worked.
Operation
Pull the plug out of the socket before carrying out any
u
work on the power tool.

Starting Operation

Pay attention to the mains voltage! The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool.Power tools marked
with 230 V can also be operated with 220 V.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Switching on and off (see figure E)
– To start the power tool, push the on/off switch (7) into
position "I".
– To switch off the power tool, push the on/off switch (7)
into position "0".
Setting the impact rate
The electronic control enables continuous speed preselec-
tion in accordance with the material.
The constant electronic control keeps the preselected im-
pact rate almost constant when alternating between no-load
and loaded operation.
– Select the impact rate with the adjustment knob (5) ac-
cording to the material.
Changing the chiselling position (Vario-Lock) (see figure
C)
You can lock the chisel in 12 different positions, allowing
you to select the optimum working position for each task.
– Insert the chisel into the tool holder.
– Push the chisel adjustment ring (3) forwards and turn the
chisel to the required position with the chisel adjustment
ring (3).
– Release the chisel adjustment ring (3) and turn the chisel
until it audibly clicks into place.
