Water connection
Connection to a water line
WARNING
Health risk from return flow of contaminated water
into the drinking water network.
Observe the regulations of your water supply company.
1. Check the feed pressure, input temperature and in-
put amount of the water supply. See Chapter Tech-
nical data for the requirements.
2. Connect the system separator and water connection
of the device with a hose (minimum length 7.5 m,
minimum diameter 3/4").
The supply hose is not included in the scope of de-
livery.
3. Open the water inlet.
Venting the device
1. Open the water inlet.
2. Remove the high-pressure nozzle.
3. Start the engine according to the original instruc-
tions 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 ex-
plosion.
Do not spray flammable liquids. Do not operate this de-
vice in hazardous areas (e.g. filling stations).
CAUTION
Environmental damage.
Clean engines at places with a suitable oil separator on-
ly.
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 pressure-
less.
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.
2. Open the high-pressure gun to continue operation
again.
3. In case of extended interruptions (several minutes),
switch off the engine.
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.
1. Set the engine switch to "OFF" and close the fuel
valve.
2. Shut off the water supply.
3. Activate the high-pressure gun until the device is
pressureless.
4. Press the safety lever of the high-pressure gun to
secure the lever of the pistol against being released
accidentally.
5. Remove the water inlet hose from the device.

Transportation

CAUTION
Risk of injury, risk of damage
Be aware of the weight of the device during transport.
1. Place the spray lance with the high-pressure gun on
the hooks.
2. Coil up the high-pressure hose and hang it over the
hook.
3. Push the push handle down, and pull / push the de-
vice.
4. When transporting the device in vehicles, secure the
device against shifting and tipping over.

Storage

CAUTION
Failure to observe the weight
Risk of injury and damage
Be aware of the weight of the device during storage.
Store the device indoors only.
Frost protection
ATTENTION
Frost destroys the device if it is not completely
drained of water.
Store the device in a frost-free location.
If frost-free storage is not possible:
1. Drain excess water.
2. Pump commonly available anti-freeze through the
device.
3. Allow the device to run for a maximum of 1 minute
until the pump and lines are empty.
