5.2 Installing the spray tube/spray lance
1. Release the pressure screw from the pressure housing
and remove together with the pressure ring (see illustra-
tion on page 2).
2. Push the pressure screw onto the spray tube/spray
lance.
3. Coat all threads with installation paste before installation
(see Chapter 12.2 Consumables).
4. Unscrew the pressure ring (left-hand thread) until 1-2
threads are visible.
5. Push the spray tube/spray lance with the pressure
screw into the pressure housing.
6. Screw the pressure screw into the pressure housing (30
mm) and tighten to a torque of 160 Nm.
7. When cleaning surfaces (e.g.cleaning concrete), install
the splash guard (see Chapter 13 Accessories) on the
spray tube/spray lance.
8. Screw the nozzle holder or other water tool onto the
spray tube/spray lance and tighten to a torque of
100 Nm unless specified otherwise.
Major characteristics of the water tools
 Water tools (e.g. nozzles, turbo nozzle, Orbimaster,
Speedy) used on manually operated spray devices from
WOMA GmbH may have multiple nozzle outlet open-
ings. These may be spotlight nozzles or flat jet nozzles.
Motor-driven rotation, or self-driven rotation through an-
gled nozzles is possible (see the WOMA product
range).
 Water tools extend the range of possible uses for the
spray device. Further information is available from your
WOMA sales partner.
5.3 Installing the bypass line
1. Coat all threads with installation paste before installation
(see Chapter 12.2 Consumables).
2. Screw the bypass pipe or bypass hose connection into
the pressure housing (32 mm) and tighten onto the by-
pass connection to a torque of 100 Nm (see illustration
on page 2).
5.4 Installing the hose connection
(see illustration on page 2)
Note
Take care to ensure that only hoses approved for the max-
imum operating pressure are used.
1. Coat all threads with installation paste before installation
(see Chapter 12.2 Consumables).
2. Screw the adapter (material number 9.918-624.0) into
the pressure housing and tighten to a torque of 130 Nm.
3. Fit the seal (O-ring) in the adapter.
4. Screw the hose connection into the adapter and tighten
to a torque of 130 Nm.
5. Connect the high-pressure water jet machine to the se-
cured spray device using a suitable high-pressure hose.

6.1 Safety instructions
DANGER
Risk of injury from the high-pressure water jet
Contact with high-pressure water jets can cause irreversi-
ble injuries or even death.
Do not direct high-pressure water jets towards humans,
animals or electrical equipment.
Ensure that the product is correctly installed before use
(see chapter 5 Installation).
16
Due to the potential hazards (e.g. recoil, cutting effects of
the water jet etc.) be sure to use the product only in the in-
tended manner (see chapter 3 Intended use).
The product may only be operated by personnel who have
been trained for this and who have been instructed in the
potential hazards (see chapter 2.4 Personnel qualifica-
tions).
Wear the prescribed personal protective equipment when
spraying (see chapter 2.8 Protective gear).
Note
Do not operate the product at temperatures below 0 °C.
6.2 Before switching on the high pressure
water jet machine
The product is correctly installed and connected to the
high-pressure water jet machine. The high pressure water
jet machine is not switched on.
Perform the following steps each time before switching on
the high water pressure, i.e. when the high pressure pump
is stationary and pressurised:
1. Vent the entire high pressure water jet machine using
the filter and the vent hose on the high pressure pump.
2. Rinse the high pressure water jet machine, including the
high pressure hose, with fresh water while the product
is depressurised.
3. Check the bypass line on the water outlet.
Water must be expelled from the bypass line when the
product is not actuated.
4. 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.
5. Check the product condition for differences from its con-
dition on delivery.
Has the position of the pressure point changed, for ex-
ample? When switching from Trigger actuated to Trigger
not actuated, the water volume flow in the bypass line
must be expelled immediately.
Note
Do not use the product if the checks are unsuccessful. In
this case, have a safety inspection conducted (see chapter
9.4 Service).
6.3 Before starting spraying
The product is correctly installed and connected to the
high-pressure water jet machine.
The high-pressure water jet machine is switched on.
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.
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.
