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
1. Set the power switch to the desired temperature.
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).

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.
Cleaning
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.
gun
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).
Operation with hot water
Recommended cleaning temperatures
● 30-50 °C: Light soiling
● Max. 60 °C: Soiling containing protein, e.g. in the
food industry
● 60-90 °C: Car cleaning, machine cleaning
Operation with hot water
DANGER
Hot water
Risk of scalding
Avoid contact with hot water.
1. Set the power switch to the desired temperature.
Interrupting operation
1. Lock the high-pressure gun by pushing the safety
latch forwards.
After operation with detergent
1. Set the detergent dosing valve to "0".
2. Set the power switch to level 1 (operation with cold
water).
3. Flush the device clean for at least 1 minute with the
high-pressure gun open.
Switching off the device
DANGER
Hot water hazard
Risk of scalding
After operation with hot water, the device must be oper-
ated with an opened gun with cold water for at least 2
minutes.
1. Close the water inlet.
2. Open the high-pressure gun.
3. Switch on the pump with the power switch and let it
run for 5-10 seconds.
4. Close the high-pressure gun.
5. Set the trigger to "0/OFF".
6. Only pull the mains plug out of the socket only when
your hands are dry.
7. Remove the water connection.
8. Actuate the high-pressure gun until the device is
completely depressurised.
9. Secure the high-pressure gun by folding out the
locking catch and engaging it.
Storing the device
Note
Do not kink the high-pressure hose or the electrical line.
1. Insert the high-pressure gun in the support on the
frame together with the spray lance.
2. Roll up the high-pressure hose and the electrical
line and hang them on the supports.
