Closing the gun causes the hydraulic shutdown of the exiting water jet. After the end of the delay time
the motor-pump unit will turn into stand-by.
Don’t let the machine run longer than 3 minutes with gun closed. If it is running for some time, the
temperature of the circulating water rises rapidly. This can damage the pump.
After finishing the work press the red button (OFF) to stop the engine. Disconnect the water supply.
Open the gun. This makes the whole system is depressurized.
Turn off the machine under malfunctioning / malfunctions immediately. Raise prob-
lems in accordance with "Troubleshooting" or call the CLENA service center.
6.3 Re-Start-Up
To receive the application readiness of the high-pressure cleaner and to guarantee work free of dis-
turbance, carry out -before every Start Up- the following controls:
• Check the general situation of the machine (screw connections, sealings, etc.).
• Check accessories, high-pressure hoses and other hoses for damages and replace if neces-
sary.
• Grease the quick couplings when required with usual lubricating oil or grease.
• Check whether enough oil exists in the pump.
• Control the water filter insert. It must be free from soiling.
• Run the machine only with absolutely clean water. Rinse the water hose before connecting
with the machine. Run the machine only vertically at a horizontal level standing.
Connect the machine now, like in point 6.2 First Commissioning described, for the designated use.
6.4 Operating with chemicals (optional)
Use only biodegradable cleaning products with a pH of 7 to 12. Such cleaners must comply with the
laws and regulations that apply in the country of use.
The liquid detergent additives have to be selected according to the chemical compatibility of the sur-
face to be cleaned.
After using detergents and other chemicals the entire system has to be rinsed with clean water.
Detergents and disinfectants can be harmful. Please refer to the details of the manufacturer.
Regarding the concentration and chemical compatibility the instructions of the manufacturer have to
be observed.
Mix the chemicals in accordance with the manufacturer in a separate container. Attach the suction
hose to the chemistry of the liquid in the container. Open the double-pipe valve completely. Approx.
10% of the chemical are added to the water, depending on nozzle size and high pressure hose length.
