Using the backpack sprayer
ENGLISH 14
7.3 Spraying
Ensure that you follow all of the safety instructions
when using the backpack sprayer.
Never use the sprayer under windy conditions or if
it is raining, as this would risk widespread drifting
of the spraying agent.
Check the wind direction before starting work.
It is best to perform spraying work in the morning
or evening, as it tends to be less windy then.
 Carry the properly adjusted and prepared
device on your back.
 Hold the spray tube at the hand valve.
 Leave the hand valve closed when you switch
on the pump (i.e. do not pull the lever).
 Select the required operating pressure at the
pump toggle switch according to the required
range and delivery rate.
In setting II the pump automatically switches off
when the operating pressure is reached at the
hand valve. If the pressure drops while spraying
then the pump will automatically switch back on
again. This arrangement ensures that the full
capacity of the rechargeable battery is used in
the best possible way.
In setting I, the switch-off pressure may not
always be attained even if the hand valve is
closed, and the pump will then run continuously
as a result. In this case we recommend
switching the pump off manually via the toggle
switch during breaks in spraying.
Always completely switch off the pump via the
toggle switch before extended breaks or at the
end of spraying.
 Pull the hand valve lever (a) to spray.
The red clip can be used to secure the hand valve
in its rest position to prevent accidental spraying.
For this, pull the lever slightly away from the handle
(a) and lock the clip (b).
Never spray towards open windows or doors, cars,
animals, children or anything else that could be
damaged by the chemicals being sprayed.
Always proceed with the greatest of care when
spraying.
Ensure that you only cover the intended areas.
If the operating pressure built by the pump drops
noticeably and the pump fails to get the pressure
back up to the normal operating level, stop
spraying with the current battery and recharge the
battery.
7.4 Residual solutions / finishing spraying
Switch off the pump immediately when any air is
sucked in and sprayed out through the nozzle. This
is indicated by a mist being sprayed from the
nozzle. At this point the solution tank will still
contain a residual amount of less than 50 ml. If you
do not want to add more spraying agent and wish
to stop spraying instead, dilute this leftover amount
with one litre of water and spray it on the treated
area. After switching off the pump, hold the spray
tube facing down towards the treated area and
operate the hand valve to discharge any residual
quantities of spraying agent left in the high-
pressure hose.
Never allow the pump to run with an empty solution
tank. Running the pump dry will result in pump
damage.
Switch the pump off when you finish working with
the sprayer. Follow the steps in section 8.5
"Draining and cleaning the solution tank" to
prepare the device for storage, thoroughly wash
your face and hands with soap, take off your work
clothing and ensure that it is washed regularly.
