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
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.
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.
Switching On and Off
– To start the power tool, press and hold the on/off switch
(5).
– Press the lock button (4) to lock the on/off switch (5) in
this position.
– To switch off the power tool, release the on/off switch
(5); or, if the switch is locked with the lock button (4),
briefly press the on/off switch (5) 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
You can adjust the impact rate of the power tool when it is on
by pressing in the on/off switch (5) to varying extents.
Slight pressure on the on/off switch (5) results in a low im-
pact rate. Increased pressure on the switch causes an in-
crease in impact rate.
Changing the chiselling position (Vario-Lock)
You can lock the chisel in 12 different positions, allowing
you to select the optimum working position for each task.
