10.2.3.2 Filling and calibrating the balancing system (professional workshop job)
After any repair on the balancing system, fill the
balancing system. Proceed as follows:
- couple the cirrus on to the tractor (see chapter 7.1)
- create all hydraulic connections (see chapter
7.1.1.1)
- connect the (see chapter 7.1.1.3)
- lift the disc harrow from the operational position up
to the stop
- align the Cirrus on level ground
- fold down the Cirrus (except for Cirrus 3000) (see
chapter 7.2.1)
- retract the integrated running gear, i.e. the machine
rests on all tyres of the roller
- switch off the Low-Lift function
- ensure that the coulters do not touch the ground.
For this, proceed as described in chapter 5.6
- insert the depth setting pins (Fig. 227/1) with
the figure "1" facing upwards in all segments
into the upper most hole of the setting seg-
ments and secure.
- retract the integrated running gear, i.e. the
machine now rests on all tyres of the roller.
- in case the coulters still touch the ground, lower
the tractor low link arms accordingly.

The balancing system is filled with the aid of the supply
hose for the harrow pressure.
The supply hose is closed with a hydraulic tap (Fig.
228/1). The hydraulic tap is secured by a twisting
safety device (Fig. 228/2).
Figure (Fig. 228) shows the closed hydraulic tap
secured against twisting.
