Set working pressure and flow rate
Settings at the plant
Figure 4
Turning the quantity regulation valve in clock-wise direction
will result in higher working pressure and larger volume.
Turning the quantity regulation valve in an anti-clockwise di-
rection will result in lower workign pressure and smaller
quantities.
Settings at the Easy press gun (optional)
Figure 5
Turning the water quantity regulator to the right gives more
water flow and higher working pressure.
Turning the water quantity regulator to the left gives lesser
water flow and lower working pressure.
Operating with cold water
Open the water supply.
Symbol "Engine on"
Pull the lever of the hand-spray gun and set the appliance
switch (A) to "1" (engine on).
The indicator lamp for operational readiness (F) shows that
the appliance is in stand-by mode and ready to be operated.
Operating with hot water
Danger
Scalding danger!
Warning
Hot water operations without fuel will cause damage to the fuel
pump. Ensure adequate fuel supply before starting hot water op-
erations.
If required, the burner can also be turned on subsequently.
R
Symbol "Burner on"
Turn the appliance switch (A) to "Burner on".
Set the desired water temperature on the thermostat (B).
Maximum temperature is 98 °C.
Operating with steam
Danger
Scalding danger! The operating pressure must not exceed 3,2
MPa (32 bar) when operating with temperatures above 98 °C.
For shifting from hot water to steam operations, first cool down
the machine and switch it off. Then do the change-over as fol-
lows:
Replace the high pressure nozzle with the steam nozzle
(accessory).
Set the thermostat to 150 °C.
Without Easy press gun
Set the water flow regulation valve of the high pressure pump
to minimum water flow (turn in the anti-clockwise direction).
With Easy press gun (optional)
Set the water flow regulation valve of the high pressure pump
to maximum water flow (turn in the clockwise direction).
Set the water flow regulator at the Easy press gun to mini-
mum water flow by turning it towards the left.
Operations stand-by
– The appliance will switch off if the lever of the hand-spray gun
is released during operations.
– The appliance will automatically start again when you open
the gun again within the stand-by period (2 ... 8 minutes).
– If the stand-by period is exceeded, the safety time mecha-
nism switches off the pump and the burner. The indicator
lamp Operations Stand-by (F) goes off.
– To restart the appliance, set the appliance switch to "0" and
then switch on the appliance again. If the appliance is oper-
ated using remote control, the appliance can be restarted by
using the corresponding switch of the remote control device.
Selecting the nozzle
– Vehicle tyres are only cleaned using the flat spray nozzle
((25°) from a minimum spraying distance of 30 cm. The round
spray should never be used to clean tyres.
The following nozzles can be selected for all other tasks:
