Cold water mode
1. Connect to water supply and determine whether the water tank fills up completely
and the float valve stops.
2. Ignition (2) to OFF.
3. Main switch (1) to ON.
4. Open high pressure gun. The pump sucks water from the water tank and moves
the water through the heating coil to the lance, the pressure is increased.
After you close the gun, press the red pressure switch (8). The 40-Second-Stop
system is activated, i.e. after closing the gun, the pump motor is turned off after 40
seconds. When you open the gun the motor starts again.
If the gun stays closed for more than 20 minutes, the safety switch off is activated
and the machine is turned off completely, i.e. if you want to use the machine you
must first turn it OFF and then ON with the main switch.
ATTENTION!!
If the pressure is not built up immediately, there is still air
in the pump. Open and close the gun repeatedly to press
the air from the machine.

Hot water mode
Start the machine just like in cold water mode and then turn the rocker switch (2) for
the burner to ON. Then, turn the rotary switch on the thermostat, (4) located on the front,
to the desired temperature (at least 40 °C) in order to activate the burner, i.e., that fuel
is injected.
The manometer (14) on the fuel pump shows approx. 10 bars. If this reading is not displayed,
check whether
1. there is heating oil in the tank
2. the motor fuse ( 11) in the switch box (below the operation panel) has tripped.
3. the fuel sieve (15) or the fuel sieve in the pump (13) is dirty.
4
. the fuel pump does no operate smoothly or is blocked.
5. the ventilator jams.
The thermostat grants permission to open the solenoid valve; after opening the gun, the
burner starts. The burner starts and heats up the water to the set temperature. The burner
switches off as soon as the desired temperature has been reached.
To avoid substantial fluctuations especially with high temperatures the high pressure
cleaner is equipped with an after-heating feature, i.e. 13 seconds after the burner was
switched off by the thermostat, the burner is restarted and stopped again after 11 seconds.
If the temperature drops again, the burner switches on automatically thus guaranteeing the
required constant temperature.
