9.1 Control before use
When the pump is not operating, check the oil quantity in the housing of the pump. Also
check the oil level every single time before filling the tank. The level must be within the
limits which are marked on the oil lid or in the oil pot (depends on the version of the pump). If
the oil level is too low add some oil whereas be careful not to exceed the maximum allowed
level.
The air pressure in the air chamber depends on the work pressure, displayed in the diagram.
Air pressure in the chamber must never be greater than the pump’s work pressure.
9.2 Use
Before turning on pump drive, make sure that there is enough water in the tank, that all
suction lines are released, that the suction filter is cleaned and that the selection valve on the
pressure line is directed towards nozzles for cleaning the interior of main tank – for system
de-aeration.
WARNING: Never engage pump drive, when AG-TRONIK setting allows full
load of the pump.
Engage drive and let the pump rotate at minimum pressure for about a minute, so that the inlet
and outlet line of the pump de-aerate and only then can you fully load the pump.
Turn the selection pressure valve to desired function.
Be careful not to exceed the maximum allowed pressure and the maximum allowed rpm of
540. On the opposite, the manufacturer cannot be held responsible for any kind of damage
that could occur.
9.3 After use
Some chemical agents can shorten the durability of some vital parts of the pump such as rubber
diaphragms and other rubber seals. Therefore a thorough washing of the pump after each single
spraying is recommended. To do this, you will need to pump some clean water through the pump.
Let the pump operate at working pressure for several minutes. Lower the pressure and let the
pump operate for approximately one minute to blow out the rest of the liquid (pump blow-out).
In the winter, completely discharge water from the pump or protect the pump from freezing (see
chapter “MAINTENANCE AND STORAGE AFTER SEASON”).
Make sure that the valves ensure free flow of liquid
from the tank to the pump. Also check the porosity of
the suction filter insert and the suction hose (make sure
that the hose is not bent).
