5.1 Venting the appliance
· Open the water intake.
· Allow the appliance to run without the high-
pressure hose until the water emerges without
bubbles.
· Then connect the high-pressure hose.
· If the spray lance and high-pressure nozzle
have already been fitted to the high-pressure
hose, you can vent the appliance as follows:
With the hand-held spray gun open, switch
the appliance on and off several times at
intervals of 10 seconds until the water emerges
from the high-pressure hose without bubbles.
5.2 High-pressure nozzle
· The effectiveness of the high-pressure jet
depends to a great extent on the spray angle.
A 25° fan jet nozzle is usually employed
(included in standard delivery).
· Other nozzles are available as accessories.
0° full jet nozzle
for stubborn dirt.
40° fan jet nozzle
for sensitive surfaces.
Dirt blaster
for thick layers of dirt.
Variable angle nozzle
with adjustable spray angle
· At first always direct the high-pressure jet
from a greater distance at the object which is
to be cleaned, thereby preventing damage
from excessive pressure.
5. Operation
5.3 Adjusting the operating pressure
and flow rate
· You can adjust the operating pressure and
flow rate steplessly with the pressure and
volume control on the pump head:
Screwing in the adjusting screw - operating
pressure and flow rate higher
Unscrewing the adjusting screw - operating
pressure and flow rate lower
5.4 Operating with cold water
· Set the thermostat to 30°C.
· Switch the appliance switch to “ ”.
5.5 Working temperature
· The working temperature can be adjusted to
any temperature required.
