Operation
DANGER
Flammable fluids
Risk of explosion
Do not spray inflammable liquids.
DANGER
Operation without spray lance
Risk of injury
Never operate the device without the spray lance in-
stalled.
Before each use, check that the spray lance is firmly
seated. The screw connection of the spray lance must
be tightened hand tight.
DANGER
High-pressure water jet
Danger of injury
Never fasten the trigger and safety lever in the actuated
position.
Do not use the high-pressure gun when the safety lever
is damaged.
Push the safety latch of the high-pressure gun forwards
every time before starting work with the device.
Hold the high-pressure gun and spray lance with both
hands.
ATTENTION
Operation with an empty fuel tank
Destruction of the fuel pump
Never operate the device with an empty fuel tank.
Opening/closing the high-pressure gun
1. Opening the high-pressure gun: Actuate the safety
lever and trigger.
2. Closing the high-pressure gun: Release the safety
lever and trigger.
Changing nozzles
1. Switch off the device and operate the high-pressure
gun until the device is depressurized.
2. Lock the high-pressure gun by pushing the safety
latch forwards.
3. Change the nozzle.
Switching on the device
1. Set the trigger to the operating mode. The standby
mode indicator light lights up. The device starts up
briefly and switches off as soon as the working pres-
sure is reached.
Note
If the direction of rotation indicator light lights up during
operation, switch off the device immediately and rectify
the fault, see "Troubleshooting".
2. Unlock the high-pressure gun by pushing the safety
latch to the rear. When the high-pressure gun is ac-
tuated, the device switches on again.
Note
If no water comes out of the high-pressure nozzle, bleed
the pump. See help in the event of malfunctions – de-
vice does not build up pressure.
Setting the cleaning temperature
● 30 °C to 98 °C: Clean with hot water.
● 100 °C to 150 °C: Clean with steam.
1. Set the power switch to the desired temperature.
2. During steam operation: Replace the high-pressure
nozzle (stainless steel) with the steam nozzle
(brass) (see Operation with steam).

Setting the working pressure and flow rate
Pressure/quantity regulator of the pump unit
1. Turn the regulating spindle clockwise: Increase the
working pressure (MAX).
2. Turn the regulating spindle anticlockwise: Reduce
the working pressure (MIN).
Pressure/quantity regulator on the high-pressure
DANGER
Danger of a loose spray lance
Risk of injury
Take care to ensure that the spray lance screw connec-
tion does not release when adjusting the pressure/
quantity control.
Note
If you want to work with reduced pressure over the long
term, set the pressure on the pressure/quantity regula-
tor of the pump unit.
1. Set the power switch to max. 98 °C.
2. Set the working pressure on the pressure/quantity
regulator of the pump unit to the maximum value.
3. Adjust the working pressure and flow rate by turning
(variable) the pressure/quantity regulator on the
high-pressure gun (+/-).
Operation with detergent
● Use detergents sparingly to conserve the environ-
ment.
● The detergent must be suitable for the surface to be
cleaned.
Note
The guide values on the control panel refer to the max-
imum working pressure.
Note
If detergent is to be sucked in from an external contain-
er, route the detergent suction hose through the recess
to the outside.
1. Set the concentration of the detergent via the deter-
gent dosing valve according to the manufacturer's
instructions.
Note
Always initially direct the high-pressure jet at the object
to be cleaned from a distance to avoid damage due to
excessive pressure.
1. Set the working pressure, the cleaning temperature
and the detergent concentration according to the
surface to be cleaned.
Recommended cleaning method
1. Loosen dirt: Spray the detergent sparingly and let it
take effect for 1... 5 minutes, but do not let it dry.
2. Remove dirt: Rinse off the loosened dirt with the
high-pressure jet.
Cold water operation
For removing light contamination and for rinsing,
e.g. garden machines, terrace, tools.
1. Adjust the working pressure as required.
The device works in the most economical temperature
range (max. 60 °C).
