6 Hydraulic fan drive
6.1 Connecting the fan (HG)
With the PS 120/200/300/500 M1, PS 500 M2, you can convert from an electric fan to
a hydraulic fan, which is driven directly by the tractor's hydraulics.
Two hoses are provided for coupling to the tractor:
-
The return line (marked yellow, BG4) must
discharge into the tractor oil tank at zero pressure
(WITHOUT reduction)!!!
-
The pressure line (marked red, BG3) can be simply
connected to the tractor control unit.
-
When connecting the hydraulic hoses to the
tractor's hydraulic system, make sure that the
hydraulics on both the side of the tractor and of
the device is pressureless!
ATTENTION: Close the flow control valve completely before using the fan!
This prevents unintentional fan overspeed!
