Set working pressure and flow rate
Appliance setting
 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 working pressure and smaller quan-
tities.
Adjusting the pressure/quantity regulation of the trigger gun
(option)
DANGER
Risk of injury! When adjusting the pressure/quantity regulation,
make sure that the screw connection of the spray lance does not
become loose.
 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"
 Release the trigger gun. To do so, push the safety catch to-
wards the back.
 Open the trigger gun and set the appliance switch (A) to "1"

Operating with hot water
DANGER
Scalding danger!
ATTENTION
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.
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.
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 follows:
 Replace the high pressure nozzle with the steam nozzle
(accessory).
Order No.
4.116-000
4.116-001
 Set the thermostat to 150 °C.
Without pressure/quantity regulation at the trigger gun
 Set the water flow regulation valve of the high pressure pump
to minimum water flow (turn in the anti-clockwise direction).
With pressure/quantity regulation at the trigger gun (option)
 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 trigger gun to minimum wa-
ter flow by turning it towards the left.
– If the trigger gun is closed during operation, the appliance will
switch off.
– 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 operat-
ed using remote control, the appliance can be restarted by us-
ing the corresponding switch of the remote control device.
– 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:
