Clean the ventilation openings on the power
tool at regular intervals using non-metal
tools. The blower of the motor draws dust
into the housing. An excessive accumulation
of metallic dust can cause an electrical hazard.
Before putting into operation, check the
mains connection and the mains plug for
damage.
Recommendation: The tool should always be
supplied with power via a residual current
device (RCD) with a rated current of 30 mA or
less.
This double-insulated power tool is equipped
with a polarized plug (one contact is wider
than the other). The plug will only fit into the
polarized socket outlet in one position. Turn
the plug if it does not fit completely into the
socket outlet. If the plug still does not fit, have
a qualified electrician install a polarized
Handling hazardous dusts.
When working with power
WARNING
tools, such as when grinding,
sanding, polishing, sawing or for other work
procedures where material is removed, dusts
develop that are both hazardous to one's
health and can spontaneously combust or be
explosive.
Contact with or inhaling some dust types can
trigger allergic reactions to the operator or
bystanders and/or lead to respiratory infec-
tions, cancer, birth defects or other reproduc-
tive harm.
Examples of such materials and therein con-
tained chemicals, where hazardous dusts can
develop when working them, are:
– Asbestos and materials containing asbes-
tos;
– Lead-containing coatings, some wood
types such as beech and oak;
– Minerals and metal;
– Silicate particles from bricks, concrete and
other materials containing stone;
– Solvent from solvent-containing paint/var-
nish;
– Arsenic, chromium and other wood pre-
servatives;
– Materials for pesticide treatment on boot
and ship hulls;
– Stainless steel dust, metal dust and non-
ferrous metal dust.
socket outlet. Do not modify or alter the plug
under any circumstances. Double-insulated
power tools neither require a three-core
power cable nor a power connection with
ground contact.
Operate the power tool only off of power sup-
plies whose voltage and frequency values
correspond with the values on the type plate
of the power tool.
When operating the power tool in a damp
environment, it must be connected via a
ground fault circuit interrupter (g.f.c.i.).
Using special rubber protective gloves and
footwear increase your own safety.
Before mounting or replacing application
tools or accessories, pull the power plug. This
preventive safety measure rules out the dan-
ger of injuries through accidental starting of
the power tool.
To minimise the unwanted intake of these
materials:
– Use dust extraction matched appropriately
for the developing dust.
– Use personal protective equipment, such
as a P2 filter-class dust protection mask.
– Provide for good ventilation of the work-
place.
The risk from inhaling dusts depends on the
frequency how often these materials are
worked. Materials containing asbestos may
only be worked by specialists.
Wood and light-metal dust can
CAUTION
cause spontaneous combus-
tion or explosions.
Hot mixtures of sanding dust and paint/var-
nish remainders or other chemical materials
in the filter bag or the vac filter can self-ignite
under unfavorable conditions, such as spark-
ing from sanding metal, continuous sunlight
or high ambient temperatures. To prevent
this:
– Avoid overheating the material being
sanded and the power tool.
– Empty the dust collector/container in time.
– Observe the material manufacturer's
working instructions.
– Observe the relevant regulations in your
country for the materials being worked.
