5 Using the backpack sprayer
Ensure that you follow all of the safety
instructions when using the backpack
sprayer.
Every time you use the backpack sprayer, first
check it all over to ensure it is safe to use
according to section 6.1.
5.1 Spraying
x When applying spraying agent, ensure by using
appropriate measures and procedures that the
unintended release of agent to other areas is
minimized and the drift to the surrounding areas
is prevented.
x Always proceed with the greatest care when
spraying.
x Never use the device under windy conditions or
if it is raining, as this would risk widespread
drifting of the spraying agent.
x Check the wind direction before starting work
and select the spraying direction downwind of
the user.
x It is best to perform spraying work in the morning
or evening, as it tends to be less windy then.
x Ensure that you only wet what is in fact intended
to be covered with spraying agents.
x Never spray the agent towards persons,
animals, open windows or doors, cars or
anything else that could be damaged by the
spraying agent.
x Use the spray nozzle suitable for your
application. Applicable nozzles: See section 9
x When spraying, ensure that the spraying agent
is applied evenly and homogeneously to the
treated area.
Pumping and spraying:
Prime the pump with a few quick up and down
strokes of the pump lever.
Hold the spray tube at the shut-off valve in your
hand.
Start the spraying process by pressing the shut-off
valve (a).
Fig. 25
Releasing the shut-off valve stops the spray
process.
The red clip can be used to secure the shut-off
valve in its rest position to prevent accidental
spraying. For this, pull the lever slightly away (a)
from the handle and lock the clip (b).
Fig. 26
The spray tube can be rotated in the shut-off valve
– after loosening the threaded collar– this is useful
for spraying under leaves.
If the spraying agent is not applied properly, spray
nozzle or filter element could be blocked or
damaged. If necessary, clean or replace the nozzle
and the filter element.
Cleaning: See section 6.7
Replacing the spray nozzle and the filter element:
See section 6.4
5.2 Residual spraying agents /
finishing spraying
Stop spraying immediately when any air is sucked
in and sprayed out through the spray nozzle. This
is indicated by a mist being sprayed from the
nozzle. At this point the spraying agent tank will still
contain a residual amount of less than 200 ml
[6.8 oz]. If you do not want to add more spraying
agent and wish to stop spraying instead, dilute this
leftover amount with two litres [68 oz] of clean
water and spray it on the treated area.
When you finish working, prepare the device for
storage according to section 6.7, thoroughly wash
your face and hands with soap, take off your work
clothing and ensure that it is washed regularly.
