/Pressing the actuation lever down on the quick closure valve initiates the spraying process.
Only now can the pressure be set on the pressure control valve and read on the pressure
gauge. Clockwise rotation increases the pressure, counter-clockwise rotation reduces the
pressure.
The optimal spraying pressure is always dependent on the nozzle used. It lies between 1.5
and 2.5 bar for the hollow cone nozzle mounted at the factory. If the pressure in the hose line
and air vessel drops below the pressure set on the pressure regulator, the pressure regulator
closes and no spray is released to the nozzle. The pump frequency must be increased in this
case. The spray jet is interrupted immediately by releasing the actuation lever on the quick
closure valve.
Note the wind direction! Do not spray into the wind. Ensure uniform wetting
of the object when spraying.
The distance from the nozzle to the object to be sprayed should be 40-50 cm.
–Clip the spray lance to the pump lever during work interruptions and breaks.
If the pressure control valve interrupts the spray jet, there is still pressure in
the hose line and pump.

7.1 Emptying & Cleaning >>
Figures 33 - 37
Danger to health due to escaping spraying agents!
Pay attention to the safety instructions in this manual. Observe applicable laws and the spec-
ifications of the agent manufacturers when disposing of residual quantities.
Remove the pressure regulator and release the residual pressure in the tank.
–Clean the device and hose system thoroughly with water after each use (rinse
several times), actuating the pump and actuation lever on the quick closure valve
several times whilst doing so. Collect the discharge and apply as described above
diluted 1:10 onto vegetation. Leave the device to dry opened, hanging it up if
possible with the opening facing downwards.
7.2 Maintenance >>
Figure 38 - 44
You may be exposed to hazards that could injure you during maintenance
work. Wear safety gloves and protective clothing, if necessary.
Completely depressurise the hose line by pulling the actuation lever on the quick closure valve,
even if the device is empty, and dispose of any remaining liquid in the system onto vegetation.
The sealing ring in the container cap and all other moving parts must be regularly greased with
resin- and acid-free grease.
Observe the national regulations concerning occupational safety which apply to the place of
operation as well as the applicable national regulations for operations. An expert inspection must
be performed – ideally by the maintenance service of the manufacturer – to establish whether
hazard-free operation remains possible. This should be performed in the event of defects that
may impair safety in particular, and must be performed at least every 5 years in any case.
