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 pressure
cleaner meets these three requirements - if
necessary by providing training by per-
sons 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 accor-
dance 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 pistol
or disconnect the hoses before the
high pressure cleaner has been
switched off and the pressure has
been relieved.
•
Use only original high pressure

SAFETY INSTRUCTIONS
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 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, 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 regulations.
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 avoid-
ed.
•
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.
•
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.
