Before starting work with the product using high water
pressure, perform the following checks:
1. Check the bypass line on the water outlet.
Water must be expelled from the bypass line when the
product is not actuated.
2. Actuate the product under high pressure several times
in a safe area and check the valves on the bypass and
the leakage holes for leaks.
3. Check that the trigger and the trigger catch are function-
ing smoothly and freely.
The trigger must return automatically to its original posi-
tion after actuation and engage into the trigger. It should
only be possible to actuate the trigger when the trigger
catch is actuated once again.
4. With the help of the supervisor, check whether the
planned working pressure of the high pressure water jet
machine is reached.
Note
Do not use the product if the checks are unsuccessful or if
an abnormality or unexpected situation is determined. In
this case, have a safety inspection conducted (see chapter
9.4 Service).
6.4 Starting up the product
The product is correctly installed and connected to the
high-pressure water jet machine.
The high-pressure water jet machine is switched on. 
Product checks in accordance with Chapter 6.2 Before
switching on the high pressure water jet machine and
Chapter 6.3 Before starting spraying are successful.
Note
Depressurised jet liquid flows out of the bypass line when
the high-pressure water jet machine is switched on and the
product is not actuated.
1. Actuate the trigger safety catch. Do this by pressing the
trigger safety catch down.
2. Actuate the trigger.
Actuating the trigger closes the bypass line and causes the
spray fluid to be emitted under pressure out of the nozzle
of the water tool.
Note
Non-corrosion resistant materials can be corroded by the
emitted high-pressure water jet.
7 Shutting down
7.1 Safety instructions

DANGER
Risk of injury from the high-pressure water jet
A high-pressure water jet can escape from a pressurised
high-pressure water jet machine.
Ensure that all components of the high-pressure water jet
machine are depressurised after shutting down the prod-
uct.

CAUTION
Hot surfaces
Touching the surface of the product can cause burns or
scalding.
Wear personal protective equipment.
Do not touch any elements of the product after using it with
hot water.
Allow the product to cool down after hot water operation or
flush the spray device using cold water operation.
7.2 Shutting down the product
Note
Depressurised jet liquid flows out of the bypass line when
the high-pressure water jet machine is switched on and the
product is not actuated.
1. Release the trigger. The trigger automatically locks onto
the trigger catch.
2. Check that the trigger catch is correctly engaged by ac-
tuating the trigger.
3. Switch off the high-pressure water jet machine and se-
cure it against being switched on again.
4. The high-pressure system must be depressurised. To
do this, completely discharge all residual pressure.
5. Disconnect all supply lines from the product in the re-
verse order (see Chapter 5 Installation).
8 Storage
The following applies to this product and, unless specified
otherwise, to all other water tools:

Clean after finishing work.

Store in a frost-protected place.

For long-term storage, blow out the product with com-
pressed air and conserve using a suitable preservative.
