Hydraulics
Spray Pump Solenoid
The liquid spray pump solenoid is a single acting
spring return solenoid and is built into the liquid
pump control manifold. When this solenoid is
activated, fluid is forced to travel to the needle valve
before travelling to the hydraulic drive for the liquid
spray pump.
Spray Pump Needle Valve
The liquid spray pump needle valve is built into
the liquid spray pump control manifold. This valve
enables the speed of the pump drive to be adjusted.
Do not run it faster than 4200-4400 rpm on
standard fitment centrifugal pump or 400-540 rpm
on optional fitment diaphragm pump.
If the pump still rotates when the pump has been
turned off, the 10 bar check valve that is in the tank
line from the pump needs replacing.
Setting Spray Pump RPM
1. Park the sprayer on even level ground. Leave the
park brake on so the cabin access ladder remains
down.
2. Chock all wheels of the sprayer, ensuring it cannot
roll while it is being worked on.
3. Allow the hydraulic oil to reach operating
temperature.
4. Set engine to around 2000 rpm.
5. Switch spray pump on.
6. Hold the outer adjuster and loosen the locknut
behind it.
7. Set the spray pump speed to 4200-4400 rpm on
standard fitment centrifugal pump or 400-540
rpm on optional fitment diaphragm pump. Rotate
clockwise (wind in) to decrease the speed, rotate
anti-clockwise (wind out) to increase the spray
pump speed.
8. Hold adjuster and tighten the lock nut.

Suction & Delivery Lines
• Use good quality suction hose and fittings that will
not collapse or leak air under suction.
• If pumping water from structures other than
storage tanks, we recommend the use of an
appropriate sized floating filter equipped with a
check valve.
• It is essential that the suction line to the pump is
the same size as the suction port (3").
A smaller size delivery line can be used but will
reduce pump output.
Hydraulic Fill Pump (Optional)
The fill pump is controlled by the valve block
mounted on the left hand side chassis rail under the
cabin area.
