When working with the liquid circuit only, it is not necessary for the
fan to be on. Therefore, it is advisable to put the gear box in the neu-
tral (off ) position.
The gear box is behind the pump. When the gear lever (A) is in the
middle position, the gear box is in neutral.
If you cannot get the gearbox into gear because of interference
between the teeth and sprockets, engage the PTO for a few seconds
and try again.
Gear Box
WARNING! Both the pump and fan should be at a complete
stop before attempting to change gears in the gear box.
The maximum number of revolutions when in use is 540 rpm. The
diaphragm pump is self-priming and can be run dry without dam-
age.

ATTENTION! See “Maintenance” section for how frequently the
pump needs to be checked.
WARNING! Make sure the pump is properly greased before
operating the sprayer.
The air pressure in the damper on the HARDI® diaphragm pump is
factory preset at 30 psi (2 bar). This is suitable for nozzle spray pres-
sures between 45 and 220 psi (3 and 15 bar). If different nozzle pres-
sures are required, set pressure damper at pressures indicated.
