Depth setting
In working position the packer carries the weight
of the machine. The working depth is adjusted
on the packer.
The horizontal position of the machine is ad-
justed at the front on the upper link.
The depth setting takes place mechanically or
(optionally) hydraulically.
Mechanical depth setting
To adjust the working depth, aluminium clips are
inserted in or removed from the adjustable sup-
ports on the packer, see chapter Aluminium clips .
1. Lower the machine in the field.
2. Switch the control unit for tractor link arm
hydraulics to floating position.
3. Align the machine horizontally with the up-
per link.
4. If necessary remove or insert aluminium clips
at the supports until the required working
depth is reached.
5. Place the same number and colour of clips on
both supports (same total thickness).
6. Align the machine horizontally again with the
upper link.
7. To limit the downward movement of the pack-
er (e.g. when lifting out): Insert aluminium
clips at the top of the support.

Hydraulic depth setting
With the hydraulic depth setting one can adjust
the working depth in the field and during use.
The hydraulic depth setting is ideally combined
with a hydraulic upper link arm.
WARNING
Danger of injury
¾
Make sure no persons are in the danger zone
during the adjustment and selection of the
working depth.
1. In the field lower the machine and switch the
tractor link arm to floating position.
2. Align the machine horizontally with the up-
per link.
3. In working position use the additional con-
trol unit to adjust the packer height, until the
desired working depth is reached. The scale
shows the working depth.
4. Level the inclination of the machine with the
upper link arm.

Pressure accumulator
As a measure to avoid erratic behaviour of the
machine under certain operating conditions, the
hydraulic depth setting is equipped with a pres -
sure accumulator.
