11. Operation
m CAUTION! For your safety, the ma-
chine must be held only at the two han-
dles (2 and 4, Fig. A)!
This will avoid the danger of an electric
shock through contact of lines during
chiselling.
Always keep the chiselling tools sharp.
m NOTE:
• Work only at low pressure when chis-
elling.
• Excessive pressure loads the motor un-
necessarily.
• Sharpen the chisels in time and replace,
if necessary.
Dust/Chip Extraction
Dusts from materials such as lead-con-
taining coatings, some wood types, min-
erals and metal can be harmful to one's
health. Touching or breathing-in the dusts
can cause allergic reactions and/or lead
to respiratory infections of the user or by-
standers.
Certain dusts, such as oak or beech dust,
are considered as carcinogenic, espe-
cially in connection with wood-treatment
additives (chromate, wood preservative).
Materials containing asbestos may only
be worked by specialists.
• Provide for good ventilation of the work-
ing place.
• It is recommended to wear a P2 fil-
ter-class respirator.
Observe the relevant regulations in your
country for the materials to be worked.

12. Electrical connection
The electrical motor installed is con-
nected and ready for operation. The
connection complies with the applica-
ble VDE and DIN provisions.
The customer's mains connection as
well as the extension cable used must
also comply with these regulations.
Important information
In the event of an overloading the motor
will switch itself off. After a cool-down
period (time varies) the motor can be
switched back on again.
Faulty power supply cables
Insulation damage often occurs at power
supply cables.
Causes are:
• Pressure points when power supply ca-
bles are routed through the window or
door gaps.
• Bends due to improper fastening or
guiding of the power supply cables.
• Interfaces by running over the power
supply cables.
• Insulation damage by pulling off the wall
outlet.
• Cracks due to ageing of the insulation.
Such defective power supply cables must
not be used and are extremely dangerous
to life because of the insulation damage!
Check power supply cables regularly for
damage. Make sure that the power ca-
ble is not connected to the mains supply
when you check.
