DANGER
Risk of injury!
Device, tubes, high-pressure hose and connections must be in faultless condition. Otherwise, the device must not be used.

Unpacking

Check the contents of the package when unpacking.
Notify the dealer immediately in the case of shipping damage.

Checking the oil level in the high-pressure pump

Place the device on a flat and level surface.
Check the high-pressure pump oil level at the oil level indicator. The oil level must be in the middle of the oil level indicator.
Top up the oil if necessary. For oil type, see Chapter Technical data.

Starting up the engine

Before initial start-up of the engine, read the original instructions for the engine and observe the safety instructions.

Check the engine oil level

Check the oil level in the engine. Do not start up the device if the oil level is low.
Top up the oil if necessary. For oil type see Chapter Technical data

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

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.

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

Interrupting operation

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.
