dle, kickback forces are produced at the spraying device and when the spray lance is held at an
angle, a torque is also created. The spray handle and spray lance must therefore be held firmly
with both hands • Check that cleaning will not result in dangerous substances (e.g. asbestos,
oil) being washed off the object to be cleaned and harming the environment • During use of
high pressure cleaners, aerosols may be formed. Inhalation of aerosols can be hazardous to
health. The employer shall perform a risk assessment in order to specify the necessary protec-
tive measures regarding aerosols, depending on the surface to be cleaned and its environment.
Respiratory masks of class FFP 2, an equivalent or higher are suitable for the protection
against hydrous aerosols • This machine has been designed for use with the cleaning agent
supplied or recommended by the manufacturer. The use of other cleaning agents or chemicals
may adversely affect the safety of the machine • Risk of explosion – Do not spray flammable
liquids. Do not clean delicate parts made of rubber, fabric, etc. with the jet nozzle. Keep some
distance between the jet nozzle and surface in order to prevent the surface from damage.
4 Transport
For safe transport in and on vehicles we recommend to prevent the equipment from sliding and
tilting by fixing it with belts. For transport and storage at temperatures around or below 0°C,
anti-freeze should be drawn into the pump beforehand (Please refer to Operating Instructions).
5 Water connection
This machine is only allowed to be connected with the potable water mains, when an ap-
propriate backflow preventer has been installed, Type BA, according to EN 60335-2-79. The
backflow preventer can be ordered under number 106411177,106411178,106411179,106411184.
The length of the hose between the backflow preventer and the machine must be at least 12
meters (min diameter 3/4 inch) to absorb possible pressure peaks. Operation by suction (for
example from a rainwater vessel) is carried out without backflow preventer. The suction set can
be ordered under number 61256.
WARNING
Water that has flowed through backflow preventer and high pressure washer is
considered to be non-potable.
6 Electrical connection
The electric supply connection shall be made by a qualified electrician and comply with IEC
60364-1. It is recommended that the electric supply to this machine should include either a re-
sidual current device that will interrupt the supply if the leakage current to earth exceeds 30 mA
for 30 ms or a device that will prove the earth circuit. Switching on the cleaner may cause volt-
age fluctuations. Voltage fluctuations should not occur if the impedance at the transfer point is
less than 0.15 Ohm. If in doubt ask your local electricity supplier.
WARNING
Inadequate extension cords can be dangerous. If an extension cord is used, it
shall be suitable for outdoor use, and the connection plug has to be kept dry and off the ground.
It is recommended that this is accomplished by means of a cord reel, which keep the socket at
least 60mm above the ground. Always unwind cord from the reels completely to prevent the
power cord overheating • Disconnect the power cord from the power source by pulling the plug
only (do not pull or tug the power cord).
