– 3 m reinforced supply hose
– Universal coupling to the pressure washer
This enables the pressure washer to draw water up to 0.5 m
above the water level in the source. This can take up to ap-
prox. 60 seconds.
Submerge the 3 m hose in water to displace the air. Connect
the 3 m supply hose to the pressure washer ensuring that
the inlet strainer remains submerged in the water source.
Turn on the machine and activate the trigger with the Lance
disconnected. If water does not come out after 60 seconds,
switch off and check all connections. If water comes out,
switch off the pressure washer and connect the spray gun
and spray lance for operation.
It is important to ensure that all hose and coupling connec-
tions are of good quality, air tight and that all washers are in
good condition and correctly seated in place. Failure to do
so may affect the self priming performance.
Water Tanks with outlet connections
When connecting the pressure washer to a water tank with a
suitable tap outlet, first connect the supply hose (not
provided) to the tank outlet, open the tap to allow the water
to displace all the air in the hose and then connect to the
pressure washer.
