who are trained to handle the machine (instructions
and the operating manual).
• The machine may only be used in a dry and frost-free
environment and may not be used outside.
• Ensure that the current supply wire (power supply
cord) is not damaged by external influence (squash-
ing, driven over, tugged, etc.).
• Check the power supply lead regularly for signs of
damage or ageing.
• The device may only be used if the power supply cord
is free of defects.
• If replacing the power supply cord, only use HO7RN
5 x 4 mm
2
rubber-insulated cable.
• If replacing the power plug, use a CEE plug SH/32
Amp. according to the VDE 0165 section 7.1.4 safety
standards. Adaptors are not authorised.
• Only qualified personnel may replace the power sup-
ply cord and the power plug.
• If the power supply cord and the power plug need to
be changed, comply with the replacement equipment
named by the manufacturer.
• The power plug may only be plugged into the power
source once the dust extractor has been set up at its
site of operation. Connection to CEE plug (i.e. wall
socket) with a delayed 25A fuse.
• Always unplug the dust extractor if it is not in use, or
if moving it from one place to another and before
cleaning or maintaining it or removing and replacing
removeable parts.
• Only use original spare parts when operating the
machine.
• If the device is to be stored (in a dry room) for a
long period of time, insert new chip sacks, switch the
machine off, roll up the power cord and ensure that
unauthorised personnel does not have access to the
machine.
• The filtered air from the dust extractor may only be
recycled into the room it was extracted from.
• The machine is only designed to extract dust from
woodworking machines which do not produce sparks
(Note: according to the BGI 739 (wood institute for
statutory accident insurance and prevention) such
machines are breakers, multi-blade circular saws and
wide-belt sanding machines used to manufacture
chipboards, doors, fillets and parquet flooring.
• Extracting other types of dust than wood dust is only
authorised with the express agreement of the machine
manufacturer.
• The machine may only be operated in non-explosive
areas. It is not authorised to use the machine in areas
where there is the danger of a gas explosion.
• It is not authorised to collect mixtures of combustible
dusts and liquids.
• The machine is not designed to extract liquids.
• Only sheet metal pipes and inflammable flexible
hoses with metal filaments, for electrostatical earthing,
may be used to connect to the machine. Ensure that
the electrostatical earthing is continuous.
• To avoid unauthorised heating, the direction of rota-
tion of the ventilating fan must be monitored.
• The machine is designed to extract combustible dusts
of Class 1 and 2 of the dust explosion classes (Kst-
value max. 300 bar m s-1), (see ElexV §3(4)).
• This device is not, from a safety point of view, de-
signed to absorb or extract explosive or similar materi-
als according to §1 from the law on explosives, nor
dusts categorised as a St 3 dust explosive class, nor
combustible liquids and mixtures of combustible dusts
and combustible liquids.
