ter volume will flow back to the pump
suction side.
Overflow valve is set and sealed by the
manufacturer. Setting only by customer
service.
– only for Advanced variant
– If the hand spray gun is closed, the
overflow valve opens and the entire wa-
ter volume will flow back to the pump
suction side.
– If the trigger gun is closed, the water
pressure in the high-pressure hose is
reduced. This reduces the actuating
force of the trigger gun and increases
the service life of the device.
Overflow valve is set and sealed by the
manufacturer. Setting only by customer
service.
The safety valve opens when the overflow
valve is defective.
The safety valve is set by the manufacturer
and sealed. Setting only by customer ser-
vice.
The lack of water fuse shuts off the engine
when the water supply is scarce (water
pressure too low).
The indicator lamp "lack of water" will illumi-
nate.
The thermostat valve protects the high-
pressure pump from unacceptable heating
during circuit operation when the trigger
gun is closed.
The thermostat valve opens when the per-
missible water temperature of 80°C is ex-
ceeded and lets out the hot water into the
open.
The motor protection switch interrupts the
electric circuit if the motor is overloaded.
DANGER
Risk of injury! Device, supply lines, high-
pressure hose and connections must be in
faultless condition. If they are not in a per-
fect condition then the device must not be
used.
Replace the transport screw with the
supplied bleed screw.
Check oil level of the high pressure
pump.
The oil level must be at the centre of the
oil level display.
Add oil if required (see technical speci-
fications).
몇 WARNING
Risk of injury due to unsuitable accesso-
ries. Only use accessories that are ap-
proved for the working pressure of the de-
vice (see "Technical Data").
Only install accessories while the device is
switched off.
Maximum tightening torque of the screwed
connections of the high-pressure hose; 20 Nm.
Connect high pressure hose and spray
pipe to the hand spray gun.
Mount the power nozzle on the spray
pipe. Tighten covering nut firmly.
Connect the high pressure hose to the
high pressure connection point of the
machine.
– For connection values refer to technical
specifications.
– The electrical connections must be
done by an electrician according to IEC
60364-1.
몇 WARNING
The highest allowed net impedance at the
electrical connection point (refer to techni-
cal data) is not to be exceeded.
In case of any uncertainty regarding the
present net impedance at your connection
