or 30 milliamperes. In the event of an accident these
devices switch off before the current becomes
dangerous.
A qualified electrician can install a residual-current
device in your building´s electrical system as a
permanent fixture.
Alternatively your electrical dealer can supply you
with a plug-in residual-current device for inserting
between the wall socket and the power cable.
Devices of this type are produced by various
manufacturers. When working outdoors, remember
to use only devices which are protected from rain
and moisture. These devices bear the symbol
or are marked with the protection code „IP 44“.

Steps before putting the unit into
operation
Note the regulations of your local water supply
authority.
Water connection
Screw the water supply hose to the cleaner´s water
inlet connection (we recommend using a reinforced
hose with an internal diameter of at least 12-13 mm
= 1/2“).
Screw the high-pressure hose to the cleaner´s water
outlet connection. Make sure that all the connections
are tightened securely and that no air can enter.
Important!
Never operate the cleaner without water. Make
sure that there is always a continuous, sufficient
water supply (at least 11-12 l/min). Operating the
cleaner without water will cause severe damage
to the seals.
The supply water must be free of dirt, sand and
other contaminants. If necessary, install a filter in
the water inlet.
The supply water must contain no aggressive
cleaning agents or solvents.
The maximum water supply temperature must
not exceed 60°C (intermittent operation).
Areas of application
For cleaning transport equipment, agricultural
vehicles and rooms.
All types of cleaning jobs in the food industry,
livestock farms, dairies and abattoirs.
For cleaning drainage pipes, floors, walls,
bathing and sanitary facilities, glass exteriors.
For blasting with abrasives.
Electrical connection
You are to connect the cleaner only to a properly
installed mains socket with earthing contact. If in
doubt, consult an electrician.
Compare the data on the unit´s rating plate with the
data of your own mains supply to make sure that the
cleaner can be operated from your mains, and install
a 16 A mains fuse if not already available. Only now
are you allowed to insert the plug in the mains
socket.
