The fan pressure hose (black) must be connected to
a circuit capable of continuous flow at high volume.
To distinguish hoses on the same hydraulic circuit,
refer to the handle symbols. The hose with an
extended-cylinder symbol feeds a cylinder base end.
The hose with a retracted-cylinder symbol feeds a
cylinder rod end.
For the hydraulic fan, connect the hose with a
retracted cylinder symbol to the pressure side of the
motor.
The fan motor further requires connecting a (third)
case drain line, which returns lubricating/cooling
fluid.
Marker hoses are provided on the cart even if
markers are not installed on the implement.
Fan Hydraulic Motor Seals
Equipment Damage Risk
Case drain hose must be attached first,
before the inlet and return hoses are
connected, to prevent damage to hydraulic
motor seals.
The case drain has the smaller 6.4 mm ID
hose and small, flat-face, low-seep
connector. Do not connect the case drain
line to a power-beyond port.
The case drain hose must be detached last,
to prevent damage to the fan motor.
To allow pressure relief during temperature cycles, it
is normal for this line to release small amounts of oil
even when stored with the connector elevated.
Low pressure (case) drain connection:
1. Attach the case drain hose to the low pressure
drain connection.
2. Connect the low pressure motor return hose,
marked SUMP, to a high volume low pressure
return port. The sump line has a large 2.7 cm
diameter quick coupler.
3. Connect hydraulic hoses to tractor remotes.
Brake Connections
Braking Hazards
The operator must understand when drill
brakes are engaged and when they are
released. Also understand and comply with
tractor operational restrictions when trailer
brakes are used.
Hydraulically controlled or air controlled braking
systems are available for the drill.
In both systems, the tractor’s trailer brake system
actuates the brakes on the drill.
Tractor trailer braking systems are normally
integrated with the tractor brakes, and operate the
trailer brakes when tractor brakes are used during
tractor movement.
The trailer braking system may or may not be
integrated with the tractor parking brake system.
Trailer brakes typically are not automatically engaged
when the tractor transmission is in park, and may not
be engaged by any tractor emergency brake.
