General safety instructions
3.2.5 Information on special risks related
to electricity
3.2.5.1 The appropriate DIN-/VDE rules are to be ob-
served.
3.2.5.2 Electrical connection have always be free of dirt
and humidity.
3.2.5.3 Use only original rated fuses!
Switch the machine off immediately when there is a
disturbance of the electric power supply!
3.2.5.4 When a live high-voltage line has been touched
or cut:
– Do not touch the machine, but do not leave it alone.
– If possible, drive the machine out of the hazardous
location.
– Warn others not to come near or touch the machine.
– Have someone switch off the electric power supply
to the line.
– Leave the machine only when you can be sure that
the touched or cut power line has been switched
off.
3.2.5.5 When using the machine, keep a safe distance
to electric cables.
When working in the vicinity of electic cables (e.g.
overhead lines), make sure that the machine or
equipment never comes near those electric cables.
DANGER FOR YOUR LIFE!
Inform yourself of the safe distances which must be
kept to electric lines or devices!
3.2.5.6 Only a qualified electrician may work on electric
systems, components or process materials and must
supervise the staff; and the electrical engineering
rules and accident prevention regulations must be
observed!
3.2.5.7 If required or stated, the machines or system
components must be disconnected from the power
supply before inspection, maintenance or repair. First
check that the disconnected parts are no longer live,
then ground and bridge them and make sure that any
live parts which are near them are insulated.!
3.2.5.8 The electric parts of the machine must be regu-
larly inspected and thoroughly checked. Any faultse.
g. loose connections or charred cables- must be
cleared immediately.
3.2.5.9 When work has to be carried out on live parts,
a second person must be present to cut the power
supply or turn the main power switch off in case of an
emergency. The work area must be secured with a
red and white warning chain and a warning sign. Use
voltage-insulated tools only!
3.2.5.10 When work has to be carried out on high-volt-
age components, switch off the power supply, dis-
connect the concerned parts from the power supply,
connect the supply cable to earth and short-circuit
the components - e.g. capacitors - with a grounding
rod!
3.2.5.11 If used, mobile electrical apparatus, connect-
ing cables with plugs, extension cables and equip-
ment power cables with their plug attachments are
to be checked at least once every six months by an
electrician or by means of suitable testing apparatus
operated by a person with knowledge of electrics, to
ensure that they are functioning correctly.
3.2.5.12 Protective installations with fault current pro-
tection units are to be checked for their effectiveness
at least once a month by a person with knowledge of
electrics.
3.2.5.13 Fault current and fault voltage protection units
are to be checked for correct operation by actuating
the test facility
– once on every working day in the case of mobile
plant,
– at least once every six months in the case of non-
mobile plant.
3.2.6 Gas, dust, vapour, smoke
3.2.6.1 Welding, grinding, sanding or using a flame on
the machine is prohibited unless it has been explicitly
permitted; since there may be a risk of fire or explo-
sion.
3.2.6.2 Ensure that ventilation is sufficient and remove
all dust and flammable material from the machine
and surroundings before welding, grinding, sanding
or using a flame on the machine (risk of explosion)!
3.2.6.3 When working in small or narrow rooms, ob-
serve the national regulations which may exist!
3.2.6.4 Combustion engines must be used in suffi-
ciently ventilated rooms only! Never leave the engine
running in enclosed or confined spaces! The exhaust
fumes contain the poisonous gas carbon monoxide!
3.2.6.5 Check all pipes and lines, hoses and screwed
joints regularly for leakage and visible damage! Clear
any fault immediately/have any fault cleared immedi-
ately!
3.2.7 Noise
3.2.7.1 Noise-absorbing elements of the machine must
be in their proper places during operation of the
machine.
3.2.7.2 Wear hearing protection as required (e.g. ac-
cording to the valid accident prevention laws/occupa-
tional health and safety aws).
