Safety Valve
1. The 1 inch return line must be connected to the relevant return line port (dumping port) for
constant oil flow systems, according to the tractor's manual. It may not be connected to the
normal quick couplers of the tractor . The system is equipped with a safety valve of 20 Bar . If
the return line is not coupled and oil pressure exists, the pressure line allows the safety valve to
release the oil in order to protect the oil cooler.
NB : With high oil flow rates the oil cooler can still burst.
2. The ½ inch pressure line is connected to the standard
quick couplers.
3. Set the oil flow rate at the chosen connector to a ¼ of its
capacity before it can be activated for the first time.
4. With the hydraulic pressure line and the return line
coupled to the tractor, make sure the lids of the bins
and metering units are sealed.
5. Activate the tractor control valve to channel oil flow to the fan motor.
6. Make adjustments to the oil flow rate to change the air pressure reading to correspond with the
table in clause 3.3.3.
