Nozzle holders
As standard, mist blowers are equipped with double diaphragm nozzle holders and various nozzle
inserts (nozzles and their flows are described in a separate chapter). Nozzle holders are essentially
valves with the following functions:
Figure 7.12
•
a 90° rotation closes (opens) the liquid flow
to the nozzle insert. This enables the opening
or closing of individual nozzles, depending
on requirements or the height of spraying;
•
a 180° rotation opens (closes) the flow
through the other nozzle;
•
in addition, the diaphragm valve inside the
nozzle holder closes the flow at low pressure
values (closes at 0.8 bar and opens at 1.5 bar)
to prevent the fluid from dripping or leaking
out if the flow of the supply or the main valve
is closed.

Blower maintenance
General maintenance work: regular cleaning of nozzle holders, regular checking of the anti-drip
diaphragm and nozzle closing functions, checking for and repairing damaged protective screens
on the fan. Removing all foreign material (branches, leaves etc.). Checking and, if necessary,
fastening all screw connections. Checking the attachment of the multiplier gearbox, flange, pump
and fan and oil level check.
WARNING: Only switch the fan on and off with the multiplier lever when
the PTO drive shaft is disengaged!
