Do not use high-pressure hoses that
have been driven over, kinked, pressed
or bent even if there is no externally vis-
ible damage.
–
Store the high-pressure hoses in such a
way that they are not subject to any me-
chanical load.
–
Maximum tightening torque of the
screwed connections of the high-pres-
sure hose; 20 Nm.
Safety devices serve to protect the user
and must not be rendered in operational or
their functions bypassed.
The switch prevents unintented starting of
the appliance. Stop the appliance during
breaks or after operation.
The safety catch on the handgun prevents
the handgun from being released uninten-
tionally.
– only for Classic 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.
Overflow valve is set and sealed by the man-
ufacturer. 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).
