Safety Device tor Packer end Cross Feed
AP42 end AP 53
fig. 40
Cross feed end packer are fitted with an
automatie safety release whi,ch causes the
packer fines to swing away. If the baler be-
comes clogged or a foreign body has been
drawn on to the feed fable the fines deflect,
as in fig. 40 a end then automatically swing
back info working position (fig. 40). In that
war, the clogged baler will freeitself.
Briefly reducing PTO speed increases the'
deflection resistance in the packer linkage.
The ti,ght bunch of material is pushed info
the chamber end the machine resumes un-
obstructed working. The torque of the
deflecting cross-feed is set between 600 end
850 Nm end on top-feed between 750 end
850 Nm. The connecting rod must be fitted in 2nd. hole tram bottom of the ad-
justing bracket. If the fines swing away repeatedly, this indicates thaI the machine
is work,ing at the limit of its capa city. Engage the next lower tractor geer, as
frequent ti ne deflection increases wear of aH drive parts.

IMPORTANT: If fines of c;:rossfeed end packers deflect five or six limes running
end the
,
trouble stil,1 pe
,
rsists, the obstruction 'is
,
too great to be cleared by the
automatie system. In that case, shut off the pto end clear the feed fable by hand.'
On no account, attempt to remove the obstruction by reversing the PTO dri,ve,
as this is Jiikely to band the leaf spring of the automatie clearing system out of
share.
Packer with Mechanical Overloading Safety (AP 38/48)
The AP 38/48 has a mechaniwl overloading safety device instead of a deHecting
safety device in the packer system. One hex. bo.It each M6x35 DIN 933-10.9 with
two hex. nuts M 6 DIN 934-10 are acting as shear olutch safety.
Safety of Tripping Mechanism
Unintentional tripping of knotter mechanism can be prevented if safety latch
is in position "Aus". Even if baler is running the needles will s'tay in resting
position. Operation of safety latch see page 6 end 7.
Pick-up Balance Spring
T0 avoid damage to the pick-up by travelling on uneven ground the pick-up is
equipped with a torsion spring. In working posi.tion the pick-up is ba,ianced by
the torsion sproing end will be released of its own weight to fellow the contours
of the ground.

Needle protection
The needles are protected against overload.
If the upward stro
,
ke of needles is obstructed,
holt 1 (fig. 41) will break. Trace the causa end
remove it. Pul,! needle lift rod tram crank after
removing expanding pin 2 end pin 3. Take off
the te,lescop,ing tube end remove broken shear
holt. Refit needle lift rod 4 with new holt 1
(Order No. 0901.98.10.00)end fighten carefully.
