Description
Motor protection switch
The pump motor is protected from overload by a motor protecting switch. In case of
an overload the motor is switched off by this motor protecting switch. For a restart
the master switch has to be switched off and then on again. In case of a repeated
switching off of the motor by the motor protecting switch the cause of the
malfunction has to be removed.
Replacement and inspection work may
only be performed by trained personnel.
Spray pipe with spray gun
The spray gun only allows the machine to
be operated when the safety trigger is
pulled.
The spray gun can be used when the
safety trigger is pulled. The liquid is then
pumped up to the nozzle. Spray pressure
builds up and quickly reaches the selected operating pressure.
When the trigger is released the gun is closed, which prevents any further liquid
from coming out of the spray pipe.
The recoil resulting from the gun being closed opens the pressure control valve in
the machine. The pump remains switched on and pumps the circuit with reduced
overpressure. When the gun is opened the pressure control valve closes and the
pump starts to operate again at the selected pressure.
If the spray gun is closed for more than 20 seconds the motor switches off. The motor
restarts as soon as the safety trigger is pulled again.
If the gun is closed for more than 20 minutes, the safety switch-off is activated and
the high-pressure cleaner switches off completely, i.e. to be able to work with your
cleaner it has to be switched OFF and then ON again with the master switch.
After completing work with your Kränzle therm C, or if work is
interrupted, the safety catch (1) must be applied. This makes it
impossible to press the trigger by accident.
The spray gun is a safety device. Repairs may only be
performed by trained personnel. If spare parts are
required, use only those approved by the maker.
