4 - Sprayer Setup

Hydraulic Motor for Liquid Pump
Connect the two hydraulic hoses (A, B) to the tractor outlets with the
highest priority for oil distribution.
From the factory, the hoses are mounted in the ports on the motor to
match the standard setting for the direction of the pump rotation. If the
hoses are swapped, e.g. when replacing worn hoses, the motor will
rotate the opposite way. The pump performance will however remain
unchanged.
Adjustment of Oil Flow
The oil flow from the tractor is set for a pump speed of maximum 540 rpm.
1.
Make sure that you have liquid in the sprayer’ s main tank.
2.
Set the valve positions for “main tank suction” and for “spraying”.
3.
Apply hydraulic oil flow gently from the tractor.
If your tractor has a setting option, set the oil flow to 36 l/min.
If no setting is available, continue with step 4.
4.
While increasing the oil flow, check the pump speed reading on the controller display [menu. 2.1.2.17], if a speed sensor
is mounted on the pump.
At the same time, adjust the spray pressure to 3 bar.
When the pump speed reaches 540 rpm at 3 bar, the oil flow from the tractor is correctly set at 36 l/min. Keep this
setting for the tractor.
μ
ATTENTION! This adjustment is made every time the sprayer is coupled to the tractor, or if the tractor outlets have
been used for other hydraulic functions.
Inaccurate Oil Flow
Oil flow from the tractor is too high:
•
This will reduce the capacity of the liquid pump caused by a pressure drop at the flow valve.
•
It is a waste of energy (the built-in flow valve for safety is adjusted to 38 l/min).
Oil flow from the tractor is too low:
•
The pump speed is decreased - e.g. the suction from the TurboFiller is slow, when filling chemicals. Adjust the oil flow
once again in the tractor, or repair the fault on the oil flow system.
