proved for outdoor use.
– Wear suitable protection: such as ear protec-
tion, safety goggles, a dust mask for work which
generates dust, and protective gloves when
working with raw materials and when changing
tools.
– Check the plug and the cable regularly and
should either become damaged, in order to avoid
a hazard, have them replaced by an authorised
after-sales service workshop.
– Always guide the cable backwards away from the
machine.
– Take care when drilling into walls as there is a
danger of rupturing concealed gas/water pipes
or cutting through power cables.
– Only for AS/NZS: The tool shall always be sup-
plied via residual current device with a rated re-
sidual current of 30 mA or less.
