4 Using the pressure sprayer / 5 Maintenance, cleaning and storage
Pumping and spraying:
To pump, loosen the pump handle (3) by turning
out of the stop position. Pump the unit until the
operating pressure is reached in the spraying
agent tank (Fig. 6). Excessive pressure escapes
automatically through the pressure relief valve (2).
Hold the spray tube at the shut-off valve in your
hand.
Start the spraying process by pressing the shut-off
valve (5).
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).
Nozzle adjustment (Fig. 7):
Nozzle closed
Î hollow cone
Delivery rate at 2 bar:
0.45 l/min [0.119 USgal/min]
Nozzle open
(max. 1 turn, 360°)
Î coarse and narrow jet
Delivery rate at 2 bar:
0.70 l/min [0.185 USgal/min]
The spray tube (1) can be rotated in the shut-off
valve (5) – after loosening the threaded collar
(Fig. 2, pos. 1) – 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 5.5

Replacing the spray nozzle and the filter element:
See section 5.3

4.2 Transport of the pressure sprayer

The device can also be carried by the pump
handle (3), if the pump handle is pressed down
completely, and it is turned to the right and clicked
into position.
To avoid damage to the spraying agent tank during
rolling transport of the device, always tilt the device
so far back that the spraying agent tank doesn't
touch the ground.
4.3 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 250 ml
[8.5 oz].
If you do not want to add more spraying agent and
wish to stop spraying instead, dilute this leftover
amount with 2.5 litres [85 oz] of clean water and
spray it on the treated area.
When you finish working, prepare the device for
storage according to section 5.5, thoroughly wash
your face and hands with soap, take off your work
clothing and ensure that it is washed regularly.

5 Maintenance, cleaning and storage

5.1 Trial run

At least at the start of every spraying season and in
frequent use at least once a month, perform a trial
run with clean water to check the following:
x Tightness of all equipment components at
maximum permissible pressure with open and
closed shut-off valve
x Function of all active components (pressure
relief valve, shut-off valve, pump handle,
pressure gauge (depending on the model))
x Dosing and distribution accuracy of the nozzle
used by measuring the spraying agent delivery
rate according to section 5.2
Never start working if there are any irregularities or
leaks, if you can see any damage to the equipment
or if the equipment is not working properly in any
way. In this event, immediately depressurise the
device by pulling on the pressure relief valve
(Fig. 4) and have it checked by a specialist
workshop.
Before pulling on the pressure relief valve (2), the
device must always be in an upright position.
Attention: Keep the device away from your face!
