Pump and Valves
The AU8115MS sprayer is fitted with an electrically driven magnetically coupled
pump that is powered from the vehicle battery. The on/off switch for the pump is
located on the control box located in the vehicle cab.
Three valves control the flow of pesticide:
A master isolation valve that shuts off
all liquid flow.
A three way tank selector valve that
determines whether the main (100
litre) tank or the flushing (10 litre) tank
is used.
A drain valve allows the system to be
drained after use.
To check that the pump is operating
correctly place a small amount (5 – 10
litres) of kerosene or diesel oil in the 10
litre tank.
Rotate the two-way valve
towards the rear of the sprayer to select
the 10 litre tank and ensure that the
isolation valve near the filter is open
Angle the spray head downwards and
place
a
container
atomiser.
Switch on the pump at the
control box without the engine of the
sprayer running. After a short time, liquid
should start flowing from the atomiser. Flow rate to the head is controlled either the
adjustable valve or in-line orifice restrictor – refer to the Calibration section. Check
that there are no leaks from any hoses or connections.

Engine
The sprayer is fitted with a Briggs and Stratton 13 HP four stroke engine with electric
start. The engine drives a blower that provides air both to rotate the atomiser and to
carry the spray droplets away from the sprayer and towards the target.
