1. Using a 17 mm spanner, loosen locknut (A) as shown below
2. With a 4 mm Allen Key, tighten or unscrew the bolt (B) according to the
following guidelines:

Tightening torque = 6.0 Nm
(b) Closed-centre/load-sensing: Unscrew 5 full turns from the fully in position

5.8 Making connections to the tractor
There are a total of five hydraulic hoses (two for the drawbar ram) and two electrical
connections that must be connected to the tractor. They are as follows:
1. ½” male quick-release for the return line. Note: The return line must have a free
flow to tank.
2. ½” male quick-release for feed line
3. ⅜” male quick-release for load-sensing (if the tractor is load-sensing)
4. Drawbar hoses
5. 12 V / 7-pin lighting socket
6. Machine loom to control box
See the following image for possible hosing layout. Ensure that the machine operator
is familiar with all tractor connections and fittings.
WARNING: Turn off tractor before connecting hydraulic hosing
When connecting hydraulic hosing to the tractor, ensure that the tractor
engine is turned off and that the ignition key is removed. Ensure that all
hydraulic connections are correctly tightened.
