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
r.p.m.
1. Make sure that you have liquid in the sprayer’s main tank.
2. Set the valve positions for and for .
3. Apply hydraulic oil flow gently from the tractor.
If your tractor allows, set the oil flow to 9.5 gpm (36 l/min).
Otherwise, continue with step 4.
4. While increasing the oil flow, check the pump speed reading on
the controller display (if a speed sensor is mounted on the pump).
At the same time, adjust the spray pressure to 45 psi (3 bar).
When the pump speed reaches 540 r.p.m. at 45 psi (3 bar), the oil flow from the tractor is correctly set at 9.5 gpm (36 l/
min). Keep this setting for the tractor.
˜
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 10 gpm (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.
