11.8 Bale damper lift height (991 B series)
The transition between the bale being tipped off the table and onto the bale mat must
be gentle. To achieve this, the end of the operating cylinder can be adjusted. Do not
carry out this procedure with a bale on the wrapper!
1.
Raise up the bale damper and support it securely. Do not rely on hydraulic
pressure.
2.
Loosen the locking nut and screw it away from the cylinder rod.
3.
Turn the cylinder rod to lengthen or shorten the rod eye, as desired.
4.
Tighten the locking nut.
5.
Remove the support and lower the bale damper. Test the machine and re-
adjust, if necessary.

11.9 Bale damper drop speed (991 B series)
The drop speed of the bale damper may be adjusted to allow for the great variation in
bale weights. The bale should not be allowed to drop too quickly so as not to cause any
machine damage.
1.
Locate the restricter valve on the right hand side of the chassis
2.
Turn it anti-clockwise to speed up drop speed
3.
Turn it clockwise to slow down drop speed
4.
Test the machine and re-adjust, if necessary
