which must now be between 600 end 620 mm.

Packer Position Adjustment

A good shaped bole depends upon even filling
of the bole chamber by the top feed. To reach
optimum bole shops when baling different
crops, pin 6 (fig. 25) can be changed info diffe-
rent holes of adjusting bracket to obtain the
best fi,lIing of the bole chamber. By moving
pin 10 info the bollom holes of adjusting bracket
more material is moved info the opposite side
of the frame knife in bole chamber, by moving
pin 10 info the ,top holes of adjusting bracket
more material is packed on the knife side
of the bole chamber. Secure pin 10 with spring
clip in adjusting bracket.
Packer position adjustment can a.lso be made
on AP 38/48. Through adjusting pack fingers
on top end cross lead the feeding effect can
also be changed.
Timing Cross Feed to Top Feed
Align cross lead crank 4 (fig. 27) parallel to top
edge of packer box 2 end block it there. Turn
flywheel in indicated direction until packer
crank 1 (hg. 27) is in vertiwl position (crank
hanging downwards). Now push hex. shaft 14
info cross feed drive pinion 16 (fig. 23). If the
hex. shaft doesn't fit turn packer crank 1 (fig.27)
by flywheel so offen info the vertical downward
position until you canpush the hex. shaft 14
info the cross feed drive pinion.
