Operation

DANGER
Risk of explosion!
Flammable liquids or gases can ignite or cause an ex-plosion.
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.
