• The machine is not suitable for direct connection to potable water mains; a
suitable backflow preventer must be used.
• Montieren Sie den Rückflussverhinderer stets am Wasseranschluss, niemals
an der Maschine.
• Always connect the backflow preventer to the water mains, never to the
machine.
To prevent the risk of damage to the machine always be sure to use a filter.
Suction function
• The petrol pressure washer can draw water from open resevoirs, e.g. ponds or
containers.
• This function may only be used with a fibre-reinforced hose equipped with a non-return
valve and a filter.
• Do not exceed the maximum suction height of 1 metre.
• Connect the suction hose to the water inlet of the high pressure pump as described
above.
• Do not let the high pressure pump run dry.
Be aware that the output pressure and/or flow rate in suction mode may be up to
40% lower than when the machine is connected to a pressurised tap.
High pressure pump
• The high pressure pump is supplied with
a transport stopper (KK) factory-fitted to
the oil filling opening.
• Remove the transport stopper before use
and replace it with the operational stopper
(FF).
• The pump is filled with oil at the factory
(specification SAG W-30).
