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
– To start the power tool, press and hold the on/off switch
(6).
– Press the lock-on button (7) to lock the on/off switch (6)
in this position.
– To switch off the power tool, release the on/off switch
(6); or, if the switch is locked with the lock-on button (7),
briefly press the on/off switch (6) and then release it.
At low temperatures, the power tool will take a certain
amount of time to reach its full impact performance. You can
shorten this warm-up time by tapping the power tool's inser-
ted application tool on the ground once.

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 thumbwheel (9) according
to the material.
Changing the Chiselling Position (Vario-Lock)
You can lock the chisel in 16 different positions, allowing
you to select the optimum working position for each task.
– Turn the chisel adjustment switch (3) to the
Changing the Chiselling Position (Vario-
Lock) position.
– Insert the chisel into the tool holder and turn the chisel to
the required position.
– Turn the chisel adjustment switch (3) to the
Chiselling position and turn the chisel until
it audibly clicks into place.
Working Advice
Sharpening Chisels
Only sharp chiselling tools will produce good results, there-
fore sharpen your chiselling tools in good time before use.
This will ensure a long service life for the tools and good
work results.
Re-sharpening
Grind chiselling tools against sanding discs, e.g. aluminium
oxide, under a steady stream of water. Make sure that the
cutting edges show no annealing colours; this will impair the
hardness of the chiselling tools.
To forge a chisel, heat it to 850–1050 °C (pale red to yel-
low).
To harden a chisel, heat it to approx. 900 °C and quench in
oil. Then, leave it in an oven for approx. one hour at 320 °C
(annealing colour: pale blue).
Vibration damping
The integrated vibration
damping function in the main
handle and at the impact
mechanism reduces the gen-
erated vibration.
