Danger
Risk of injury!
– Only use original high-pressure hoses.
– The high-pressure hose and the injec-
tion system must be suitable for the
maximum operating pressure given in
the Technical Data.
– Avoid contact with chemicals.
– Check the high-pressure hose daily.
Do not use hoses with kinks.
Stop using the high-pressure hose if the
external wire layer is visible.
– Do not use the high-pressure hose any-
more if the winding is damaged.
– Lay the high-pressure hoses in such a
way that no vehicle can drive over it.
– 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.
When the lever of the hand spray gun is re-
leased, the overflow valve switches to cir-
cuit operation. The water flows back to the
suction side of the pump.
The thermal valve protects the high-pres-
sure pump from unacceptable heating dur-
ing circuit operation.
The thermo-valve opens when the permis-
sible water temperature is exceeded and
lets out the hot water into the open.
Thus, cold water will follow and cool the
pump.
