Safety devices

CAUTION
Missing or modified safety devices Safety devices are provided for your own protection. Never modify or bypass safety devices.

Safety lever
The safety lever on the high-pressure gun prevents the device from being switched on inadvertently.

Overflow valve
If the high-pressure gun is closed, the overflow valve opens and the entire water volume will flow back to the pump suction side.
The overflow valve is set by the manufacturer and sealed. Setting shall only be carried out by Customer Service.

Safety valve
The safety valve opens if the pressure relief valve is faulty.
The safety valve is set and sealed at the factory. The adjustment is made by Customer Service.

3. Start the engine according to the original instructions for the engine.
4. Allow the device to run until the escaping water is free of air bubbles.
5. Switch off the device.
6.  Fit the high-pressure nozzle.

Operation

DANGER
Risk of explosion!
Flammable liquids or gases can ignite or cause an explosion.
Do not spray flammable liquids. Do not operate this device in hazardous areas (e.g. filling stations).

CAUTION
Environmental damage.
Clean engines at places with a suitable oil separator only.

Turning on the Device

1. Open the water supply.
2. Start the engine with the high-pressure gun actuated according to the operating instructions of the engine manufacturer.

ATTENTION
Risk of damage
Do not pull the starter rope when the engine is running.

Note
The high-pressure nozzle can be removed to facilitate the start-up process.
● Press the lever on the high-pressure gun as long as necessary until the engine starts.

Replacing the nozzle

DANGER
Risk of injury!
Switch the device off prior to replacing nozzle and do not activate hand spray gun until the device is pressureless.

1. Secure the high-pressure gun. To do so, push the safety lever towards the front.
2. Unscrew nozzle screws and remove the nozzle.
3. Put on a new nozzle.
4. Screw on the nozzle screws and tighten them by hand.

Interrupting operation

1. Close the high-pressure gun to interrupt operation.

4.  Activate the high-pressure gun until the device is pressureless.
5. Secure the hand spray gun using the safety lever so that it doesn’t open accidentally.

Note
When the lever of the high-pressure gun is released, the engine continues to run at zero speed. The water thus circulates within the pump and gets heated.When the cylinder head at the pump has reached the maximum permissible temperature (65 °C), the therm-valve opens. Hot water is drained. Cold water will follow and cool the pump.

Finishing operation

After operating the water using saline water (sea water), open the high- pressure gun and rinse the device for at least 2 – 3 minutes using tap water.
