Safety Instructions - Nilfisk-Advance Gerni N/G-6400A Betriebsanleitung

Anybody working with the high pressure
cleaner should:
- be familiar with the safety functions,
equipment and maintenance of the
machine,
- be well-informed about the safety
and health regulations which apply
to the operation of the machine,
- have acquired a safe working tech-
nique so that accidents during work
are avoided.
It is the duty of the employer to make sure
everybody who operates the high pres-
sure cleaner meets these three require-
ments - if necessary by providing training
by persons with experience of working
with high pressure cleaners.
During use the high pressure cleaner
should be in good condition with regard
to safety. This is ensured by necessary
replacement of worn or defective parts
and by maintenance and service in
accordance with this operation guide.
The following safety instructions must be
carefully observed:
• The high pressure cleaner must be
earthed according to regulations.
• Never exceed the maximum pres-
sures and temperatures indicated
on the machine plate.
• In case of operational failures and
and when carrying out repairs or
maintenance - switch off the high
pessure cleaner at the mains switch
and turn off the water supply.
• After operation - switch off the high
pressure cleaner at the mains and
turn off the water supply. Always
lock the pistol with the safety device
on the trigger when you leave the
high pressure cleaner.
• After use of the hot water/steam
device the high pressure cleaner
must be flushed with cold water for
about 1 min.
• Never attempt to exchange the pis-
tol or disconnect the hoses before
the high pressure cleaner has been
switched off and the pressure has
been relieved.
• Use only original high pressure
hoses. Do not use alternative high
pressure hoses as they may not
comply with the safety standards
required by Nilfisk-Advance A/S.
Never attempt to repair defective
high pressure hoses yourself.
• Never allow other persons than the
user of the high pressure cleaner to
stay in the area where they risk
being hit by the jet.
• The user should be able to stand
firm and steady with sufficient
28
space around him/her so that it is

possible to adopt a proper working
posture. It is recommended to use
footwear which is flexible, laced and
with anti-skid soles.
• Do not add diesel oil during opera-
tion or when the machine is hot.
• For reasons of health and safety,
operation of oil burning high pres-
sure cleaners is only permitted
under observation of certain regula-
tions - e.g. concerning air intake
and draught.
Hot water cleaners produce about
120-150m 3 of waste gases an hour.
Therefore, it is a essential that the
cleaner is supplied with the same
quantity of air - if possible by means
of a fresh-air conduit, ventilating
plant or the like (ø350 mm or
400x400 mm). Combination of two
or more smoke flues - please see
page 75 - 76
Mounting of chimney/smoke flue
should normally be carried out by a
plumber who at the same time guar-
antees that the chimney/smoke flue
meets the local authority regula-
tions. The smoke flue of hot water
cleaners should have a diameter of
min. 250 mm and be placed 150 -
200 mm above the exhaust of the
cleaner.
In freezing weather, the chimney
should be fitted with a closing
device so that frost cannot cause
fracturing of the heating coil and
boiler.
To obtain optimum combustion it is
necessary to make combustion
tests and adjustments of the burner
as required -so the fuel and heating
capacity is utilised maximum and
sooting up of coil and boiler is
avoided.
• The high pressure cleaner should
not be used from a ladder unless
the ladder has a working platform or
other precautions providing at least
the same safety.
• Lance and pistol should always be
held with both hands. Do not over-
ride the automatic trigger release
mechanism.
• Never aim the water jet in the direc-
tion of electric installations as the jet
may then become live.
• The water jet is delivered from the
nozzle at high speed. Therefore,
never aim the jet in the direction of
people or animals.
• Hearing protection should be used
to reduce the noise loading below
85dB(A).
• It is recommended that protective
clothing be worn to avoid accidental
spraying of unprotected skin.
