Water connection/Suction
feed operation
Connection to water main
Caution!
Pay attention to the regulations of the
water supply company; according to DIN
1988, the cleaner may not be connected
direct to the public drinking water supply.
A short-term connection via a non-return
valve (Order no. 6.412-578) is allowed.
Dirty water may damage the unit. To prevent
this, we recommend using a water filter, 1”
connection (order no. 2.638-270).
For connected loads see Technical
Specifications.
n
Connect a supply hose (not supplied) to the
water outlet on the cleaner and to the water
inlet (e.g. water tap).
n
Open water inlet.
Suctioning water from an open container
n
Screw suction hose with filter (Order no.
4.440-238) to the water outlet.
n
Evacuate air from the cleaner before
operating it
– To vent the unit, unscrew the nozzle and
leave the unit running until the water
exits with no air bubbles.
– Switch off the unit and screw the nozzle
back on.
Operating the cleaner
Danger!
Observe the relative safety regulations
when using the cleaner at filling stations or
other high-risk areas.
Caution!
Only clean engines in places which
have appropriate oil separators (protection of
the environment).
Caution!
Only wash animals with the low-
pressure fan jet (see ”Selecting the type of
spray”).
Operating with high pressure
The cleaner is equipped with a pressure
switch. The motor only starts up when the
lever is retracted.
n
Unroll the required length of high-pressure
hose from the hose reel.
n
Release the handgun with the pressure
and flow control and pull the handgun
lever.
n
Set unit switch to ”I”.
n
Adjust operating pressure and flow rate
(+/–) by rotating the pressure/flow control
(infinitely variable).
Read off operating pressure on pressure
gauge.
n
At the lowest flow rate the waste heat from
the motor will heat the water to approx.
15 °C.
