Safety Instructions - Nilfisk-Advance N/G-4001A Operating Manual

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
repair - 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 os 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
space around him/her so that it is
28
possible to adopt a proper working

posture. It is recommended to use
footwear which is flexible, laced and
with anti-skid soles.
• Avoid touching the area around and
above the exhaust outlet as this
may cause burnings.
• 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 - 150 m3 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, venti-
lating plant or the like (ø350 mm or
400x400 mm). Combination of two
or more smoke flues - please see
page 23 - 25.
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 utilized 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 override the
automatic trigger release
mechanism.
• Never aim the water jet in the
direction of electric installa-
tions 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 peo-
ple or animals.
• A hearing protector should
be used to reduce the noise loading
below 85 d.s.(A).
• It is recommended that protective
clothing be worn to avoid accidental
spraying of unprotected skin.
