5.3 Regulation of pressure/water
capacity
When working at the maximum working pressure
the regulating valve of the spray lance must be
completely closed, and the valve for regulation
of the water capacity must be unscrewed (in the
direction indicated by the arrow).
The water capacity is continuously variable
between min. and max. according to the diagram
below.
Close the spray handle, screw in the valve for
regulation of the water capacity (in the opposite
direction of that indicated by the arrow). This cor-
responds to a working pressure of 40 bar and a
water capacity of about 9 I/min.
If increased water output is required, turn the valve
in the direction indicated by the arrow, until the
required amount is reached. 1 turn is equivalent to
a rise of pressure of approx. 50 bar.
If fully reduced pressure
with maximum water
output is required, open the regulating valve. The
water will now fl ow from both tubes at a pressure
of approx. 5 bar.
This can be done irrespective of the ad just ment of
the valve for regulation of the water capacity.
6.0 Frost proofi ng EN
Operation and storage in frosty weather (below
0°C).
Never leave the cleaner unless it has been emptied
of water, not even for a short period. Empty the
cleaner in the following way:
1. Disconnect and empty both the water supply and
the high pressure hoses.
2. Start the pump and allow it to run until it is
empty.
If the cleaner is not stored in a frost-proof place
between operations, it should be protected from
frost in the following way:
1. Disconnect the lance.
2. Start the machine and allow it to run without
water.
3. Place the suction hose into a container of anti-
freeze.
4. Draw in the antifreeze from the container by
activating the spray handle. Having placed the
spray handle above the an ti freeze funnel, open
and close it a few times, so that the antifreeze
can circulate.
5. Remove the inlet hose from the container. Acti-
vate the spray handle and allow the rest of the
antifreeze to run back into the container.
NB! The antifreeze will be diluted with water and
will after some time lose its effect.
IMPORTANT:
To avoid damage always ensure that the cleaner,
the hoses and the spray lance are unfrozen before
restarting. Place the cleaner and the accessories in
a warm place for some time before starting up.
