1 Introduction
Welcome to the Lely manual, the place where you can find
technical information, operating instructions, maintenance
procedures and troubleshooting information for the
Lely Welger AP baler.
Study and understand this information thoroughly before you
operate the Lely Welger AP baler. Failure to do so could result
in personal injury or damage to equipment. Please consult your
local Lely service provider if you do not understand the
information in this manual, or if you need additional information.
All information in this manual has been compiled with care. Lely
shall not be liable for errors or faults in this manual. The
recommendations are meant to serve as guidelines. All
instructions, pictures and specifications in this manual are
based on the latest information that was available at the time of
publication. Your Lely Welger AP baler may comprise
improvements, features or options that are not covered in this
manual.
6 LELY WELGER AP 530 AP 630 AP 730 AP 830
1.1 The Lely Welger AP baler
The Lely Welger AP baler is a baler that produces small square
bales from dry agricultural material such as wheat straw, hay
and alfalfa.
The Lely Welger AP baler is pulled by a tractor.
The packer, cross-feeder, ram, knotter device and pick up are
driven entirely via torsionally rigid shafts and gears. This
ensures high performance baling results, quality bales and a
long life time.
The Packer Feed consists of two (AP 830 has 3) self-deflecting
packers which prevent blockage caused by foreign objects or
damage to the machine. In case of an overload the packers can
mostly deflect and then automatically reposition themselves
ready for operation. After several ram strokes, the blockage will
be cleared. The benefits are clear due to the use of a patented
hydro packer, a further development of the tried and tested selfdeflecting packers.
Two friction clutches; one in front and one behind the flywheel
protect the universal joint and the tractor as well as the baler
drive. On the AP 530 and the AP 630, an additional shear bolt
protects the drive should an unforeseen blockage occur. On the
AP 730 / 830, this function is fully automated with an auto-reset
clutch.
The bale thrower P23, is an accessory. The thrower is driven
via its own hydraulic system and allows maximum use of the
baler’s performance. The baler is no longer restricted by the
speed of a manual worker during loading.

1.7 Proper use
The AP baler has been built exclusively for the production
of bales compressed from grain crops or hay from grasses
lying on the ground (proper use). Usage going beyond that
does not constitute proper use. The manufacturer is not
liable for damage resulting from improper use; the operator
alone bears the risk.
Proper use also includes adherence to the operating,
maintenance and servicing conditions prescribed by the
manufacturer.
The attachment of auxiliary equipment to the machine other
than at the positions provided by the factory is prohibited.
The relevant accident prevention regulations, regional
safety standards and other generally recognized safety
regulations in particular, are to be adhered to.

approved parts and equipment on the machine exclude any
liability on the part of the manufacturer for damage resulting
from this. Only original Lely spare parts are to be used.
Components covered by CE regulations must conform to
these regulations.
The machine may only be operated, maintained and
repaired by persons who are familiar with such work and

other parts of the machine.
Make sure there are no people in the danger zone during
operation. This is especially important when working near or
in areas that are accessible to the public. Keep sufficient
distance to the machine (pick-up, running gear, bale
unloading area).
Never operate the P23 thrower without a suitable trailer
behind the AP baler.
Make sure there are no objects in the field that can be
picked up by the Lely Welger AP baler.
Clean the safety decals regularly so that they remain
readable. Replace the safety decals if necessary.
After operation
Always park the AP baler on a flat stable ground.
Always use wheel chocks.

Maintenance Safety
In addition to the general safety instructions:
Switch off the tractor engine, disconnect the Power-Take-Off
(PTO) and stop all moving parts, wait until machine has
come to a complete standstill, depressurize the hydraulic
system, before doing maintenance on the AP baler and P23
thrower.
Never reach into moving parts or parts that can start to
move.
Before performing any activity on a gearbox after operation,
first permit it to cool down.
Make sure all covers and guards are reinstalled when
maintenance work is complete.
Obey the maintenance schedule in this manual.
Do not modify the AP baler and P23 thrower.
Only use genuine Lely parts.
Maintenance work may be carried out by trained expert
personnel only.
Fire Prevention
The harvested crop can easily ignite! To prevent fire:
Remove crop remains.
Ensure there are no oil leaks.
Overheating of machine parts can cause fires! To prevent
overheating of machine parts: observe the lubrication chart.
If any machine parts overheat: find and remove cause.
Keep the electrical systems of tractor and machine and the
exhaust system of the tractor in proper condition.
The existing wiring must not be used for any other
consumers than those installed in the factory or approved
by the manufacturer. Overloading the electrical lines leads
to excessive heating.
Do not smoke in the vicinity of the machine.
Noise protection
The noise level during normal field work is subject to variations
which depend on the one hand on the noise level of the tractor
and on the other hand on the deployment conditions of this
machine.
The generated noise level, measured at the head height of the
driver inside a tractor with cabins and closed window, under
normal operating conditions, is less than 70 dB (A). The
combined noise level of machine and tractor primarily depends
on the level of the noise from the tractor (radios are an
additional source of noise).
