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

u

Pull the plug out of the socket before carrying out any
work on the power tool.

Starting Operation

u

Pay attention to the mains voltage. The voltage of the
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.

u

Products that are only sold in AUS and NZ:

 Use a resid-

ual current device (RCD) with a nominal residual current
of 30 mA or less.

start

 the power tool, press and hold the on/off switch

(5)

.

– Press the lock-on button 

(4)

 to

; or, if the switch is locked with the lock-on button 

(4)

,

briefly press the on/off switch

shorten this warm-up time by tapping the power tool's inser-
ted application tool on the ground once.

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).
