8 Preparing the spray liquid and filling the
spray tank
Prepare the spray liquid according to the
instructions of the chemical manufacturer.
Always prepare the spray liquid outdoors, never in
living quarters, stables or storage rooms for food
and animal feed.
Before opening the spraying agent tank,
depressurise the device by pulling on the pressure
relief valve (Fig. 3). Before pulling on the pressure
relief valve (d), the device must always be in an
upright position.
Attention: Keep the device away from your face!
To fill the tank with spraying agent, the pump must
be unscrewed. Push the pump handle (c) down
and turn it to the left (counterclockwise) until the
handle clicks into position.
Unscrew the pump by turning it counterclockwise.
Do not use any tools!
Fill the tank no further than to the upper-most mark
on the side of the spray tank.
Overfilling the tank or spills can contaminate public
waterways, rain- and storm water channel and
must be avoided.
Wipe off spilled spray liquid without delay.
After filling, insert the pump again and refasten
firmly by turning the pump handle (c) clockwise to
prevent the spraying agent from escaping.
Refasten firmly until the pump handle clicks into
position.
Fig. 4:
Attach the respective sticker for the type of spray
liquid, such as herbicide, fungicide or insecticide to
the spray tank.
9 Use of the pressure sprayer
9.1 Spraying
xDo not use the sprayer in wind or rain.
xCheck the direction of the air movement before
starting work and spray with the air movement,
not against it.
xDo not spray towards persons, animals, open
doors and windows, cars or other objects that
may be hurt or damaged by the spray.
xEnsure that only the actual spray target will be
wetted. Always aim to obtain even and
homogenous distribution of the spray on the
treated surfaces.
Pumping and spraying:
To pump, loosen the pump handle (c) by turning
out of the stop position. Pump the unit until the
operating pressure is reached in the spraying
agent tank. Excessive pressure escapes
automatically through the pressure relief valve (d).
Hold the spray wand with the hand valve.
Fig. 5:
To spray, depress the hand lever on the valve.
Release the hand valve lever to stop spraying.
To spray the underside of leaves, lightly loosen the
spray wand cap nut and turn the wand hand tighten
again.
An uneven spray picture or reduced spray output
from the nozzle may require cleaning of the nozzle
filter insert and nozzle (chap.10.6) or the
replacement of these parts (chap. 10.4).
The pressure sprayer can also be carried by the
pump handle (c), if the pump handle is pressed
down completely, and it is turned to the right and
clicked into position.
9.2 Disposal of residual spray volume
Residual spray volumes of less than 200 ml
[6.8 oz] are no longer pumped effectively. Either
add more spray formula and continue spraying or,
when finishing off, dilute the residual volume with
2 litres [68 oz] of clean water and apply to the
already treated area.
At the end of the work, empty and clean the
sprayer according to chap. 10.6, wash face and
hands thoroughly and take off the work clothing.
Work clothing requires regular washing.

ENGLISH 5
10 Maintenance, cleaning and storage
10.1 Maintenance plan
Before starting work:
xCheck the entire sprayer is operationally safe by:
oVisual inspection of the sprayer
oChecking the tightness of all parts (at
maximum admissible pressure with the hand
valve opened and closed).
oChecking the working of all functional parts
(pump, hand valve).
oChecking the hoses and their screw
connections.
After the end of work, when changing the spray
formula, whenever required:
xCleaning the spray tank chap. 10.6
xCleaning the nozzles and filters chap. 10.6
Monthly or at the start of the season, whenever
required:
xChecking the output volume chap. 10.3
xGreasing the sealing rings chap. 10.5
10.2 Test run
When the spraying season starts and then every
month, the following items must be checked in a
test run with clean water:
xTightness of all sprayer parts at maximum
admissible pressure with the hand valve opened
and closed
xFunction of all working parts (hand valve, pump)
xDosage and distribution accuracy
xCalibration of output volume according to
chap. 10.3
In case of irregularities, damage, leaks or limited
function, do not use the sprayer but have it
checked in a specialist workshop without delay.
10.3 Calibration of the output volume
Fill the sprayer with water to the maximum mark
and spray with a working pressure of 2 bar [29 psi]
for precisely one minute. Then measure the water
volume required when refilling to the maximum
mark. The application volume must not deviate
from the indicated value (chap. 11) by more than
10%; otherwise, clean the nozzle and the filter
insert and repeat the measurement procedure.
If the application volume is not correct even after
cleaning, replace the nozzle and/or filter
insert. Chap. 10.4
10.4 Replace the spray nozzle and/or filter
xFlush the nozzle assembly with clean water.
xUnscrew the nozzle assembly.
xClean the O-rings, filter insert and spray nozzle
with clean water and soft brush. Do not blow out
the spray nozzle by mouth! Do not clean nozzles
with any hard objects!
xReplace the nozzle with a new nozzle and/or
new filter insert.
xScrew the parts of the nozzle assembly back
together (Fig. 2).
10.5 Greasing the sealing rings
Greasing the cap gasket
Fig. 6:
For proper sealing of the spraying agent tank, the
cap gasket (l) must be well greased with silicone
grease.
Greasing the pump piston sealing ring
If the pump is hard to operate, the sealing ring of
the pump piston (Fig. 10, pos. m, part no.: 10675)
should be greased with silicone grease or replaced
if necessary.
Disassembly of the pump and greasing the
sealing ring:
Fig. 7: Ensure the sprayer is empty and not
pressurised. Place sprayer securely on level
ground. If the pump is completely screwed onto the
tank, loosen the pump with 1–2 turns.
Fig. 8: Firmly hold the pump handle with both
hands and push downwards until the pump
releases from the flange housing with an audible
click. Unscrew the red flange housing from the
sprayer and remove the pump from the tank.
Fig. 9: Use a screwdriver to lever both black flange
semi-circles from the pump cylinder. The pump
piston can now be pulled from the pump cylinder.
Fig. 10: The sealing ring (m) can now be re-
greased with silicone grease or replaced if
damaged.
Assembly:
Fig. 11: Place the red flange housing correctly on
the pump piston.
Push the pump piston into the pump cylinder.
Push both black flange semi-circles onto the pump
cylinder until they lock with an audible click.
Fig. 12: Place the pump cylinder securely on level
ground. Line up the red flange housing in the exact
position and firmly push the red flange housing
down with both hands onto the pump cylinder until
the parts lock together with an audible click.

10.6 Empty the spray tank and clean all the
parts in the spray delivery system to the
nozzle
Before opening the spraying agent tank and before
disassembling the nozzle attachment, depressurise
the device by pulling on the pressure relief valve

Fig. 13:
xFlush the nozzle assembly with clean water.
xUnscrew the nozzle assembly.
xClean the O-rings, filter insert and spray nozzle
with clean water and a soft brush.
