Procedure:
Ȝ Fill the pressure sprayer tank with a minimum of
two liters of water and spray the water into a
container at a pressure of two bar for one
minute.
The quantity of water in the container must not
deviate from the spray quantity by more than ten
percent at two bar (see “Technical data”).
If the quantity is too small:
Build-up of residue in the nozzle
-> Clean nozzle and check again
If the quantity is too large:
Nozzle is damaged or worn
-> Replace nozzle
If the spray pattern is uneven:
-> Replace nozzle
13. Maintenance
The pressure sprayer is almost completely
maintenance-free.
Prior to performing any maintenance work on the
unit, always relieve the pressure via the
overpressure valve (Fig. 1/Item 11) by raising the
overpressure valve. Ensure that you observe the
safety instructions.
Ȝ The service life of the unit will be increased
dramatically if you regularly clean the diaphragm
(Fig. 5c/Item 16) and lubricate it using resin and
acid-free grease (e.g. Vaseline).
14. Cleaning/replacing the pump
diaphragm
Ȝ (Fig. 5a) To replace a defective pump
diaphragm, pull the pump/carry handle all the
way up, then turn to the left until you reach the
initial stop point. Continue to turn the handle to
the left until the cover plate (13) releases from
the bayonet lock (14).
Ȝ (Fig. 5b) Pull the pump/carry handle up and out.
Ȝ (Fig. 5c) Now press the retaining elements of the
pump diaphragm (16) out of the holder. Clean or
replace the diaphragm, depending on its state of
wear. Press the retaining elements of the new
diaphragm back into the holder. Lubricate the
new diaphragm with acid-free grease.
Ȝ (Fig. 5d) Reinstall the pump/carry handle and
press the cover plate into the bayonet seat. Hold
down the cover plate with your fingers while
pulling the pump/carry handle up and turning it to
the right. This locks the cover plate (13) in the
bayonet lock (14).
