and noise emission value may differ. This may significantly
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
Do not operate your power tool without the auxiliary
u
handle (7).
Make sure that the auxiliary handle is always
u
tightened. Otherwise you could lose control of the power
tool when working.
Swivelling the Auxiliary Handle
You can swivel the auxiliary handle (7) to any angle for a safe
work posture that minimises fatigue.
– Turn the lower gripping end of the auxiliary handle (7) an-
ticlockwise and swivel the auxiliary handle (7) into the re-
quired position. Then turn the lower gripping end of the
auxiliary handle (7) clockwise to retighten it.
Make sure that the retaining strap of the auxiliary handle
slots into the corresponding groove of the housing.
Changing the Tool
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.

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.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
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.
Start-up
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.
Setting the Operating Mode
The operating mode of the power tool is selected using the
mode selector switch (3).
– To change the operating mode, turn the mode selector
switch (3) to the required position.
Note: Only change the operating mode when the power
u
tool is switched off. Otherwise, the power tool may be-
come damaged.
Position for hammer drilling
If the application tool does not start rotating
straight away, run the power tool slowly until
the application tool starts rotating.
