2 Safety
2.1 General safety instructions
Attention!Even if all instructions are observed the machine involvesresidual dangers. Always handle the machine with care to avoiddanger to yourself and others!
Before starting work perform a visual inspection of themachine. Check whether any device has been changed or ismissing and pay attention to any unusual noise or leakswhich occur during operation.
All protective devices, as for example casing sheets, rubberskirts or distance brackets are for your safety! Never operatethe machine with defective or removed protective devices e.
Keep all safety relevant parts always in correct function.Before commissioning all guard casings must be mountedand closed!
Never perform maintenance- and repair works duringmachine is in operation.
In case of all work on movable parts or in the range of actionof movable parts: Switch off power take-off shaft, switch offtractor engine, remove ignition key and disconnect driveshaft from power take-off shaft end. Interrupt electricalconnection between tractor and machine.
Bring no metal parts close to the machine, as long theelectric control is in operation (e.g. tools, safety boots with
metal caps). Reason: unintentional triggering of proximityswitches and thus unexpected machine moves.
When carrying out work on the opened tail gate: insert tailgate safeguard (chapter 2.4 Tail gate safeguard).
Never remove any crop material from the machine while thedrive is running, or while the disconnected machine is stillmoving. Always switch-off power take-off shaft and tractorengine first.
During work only the driver must be on the tractor. Riding onthe machine is prohibited!
Never step onto the maintenance platform during machine isin motion. Before stepping onto the maintenance platform:
stop machine, switch-off power take-off shaft and tractormotor, take out ignition key and wait for standstill of themachine.

17/126
WELGER RP 405 RP 435 RP 505 RP 535 9
Do not step onto the drawbar or other parts of the machine,when the machine is in operation. Keep sufficient distance tobaler (pick-up, running gear, bale unloading area).
Before threading the tying material: stop machine, switch-offpower take-off shaft and tractor motor, take out ignition keyand wait for standstill of the machine. Make the controlpowerless (disconnect electrical connection to the tractor).
All protection devices must be mounted to the baler andmust be in correct state. Prior to opening the protectiondevices switch-off power take-off shaft and tractor motor andwait for standstill of the machine.
Block the wheels of the baler with wheel chocks whenmachine is parked. Carry the chocks on the machine whentransporting it or during field use.
When opening the tail gate keep a minimum distance of 2 mfrom electrical high-voltage lines.
There is danger of cutting during works at the net knife or at
the knives of the cutting device of the baler. Wear protectivegloves.
Works at the magnets of the knife holders: the function ofcardiac pacemakers can be interrupted by magnetic fields.
Works at the magnets of the knife holders: Danger of injuryby splinters never hit the inserted knives from below with astriking tool. Magnets could be damaged!
Maintenance work may be carried out by trained personsonly. All maintenance- and repair works that are not part ofthis operating instruction must be carried out by authorisedpersonnel only.
Replace wearing parts of the braking system only at both
sides.
Prior to disassembling the complete pick-up the machinemust be secured against backward tilt.
In case of locations on a slope: place the round bales alwaysso that they cannot move automatically.

2.2 Noise level
The EC directive 86/188/EEC (or EC directive 2003/10/EC)concerning noise at the workplace instructs employers andemployees to assess noise at the place of work and to control it.The noise level during normal field work is subject to variations
which depend on the one hand on the noise level of the tractorand on the other hand on the deployment conditions of thebaler.
The noise level generated by the WELGER balers, measured atthe head height of the driver with the tractor cabin windowopen, is, under normal operating conditions, less than 70 dB(A). The combined noise level of baler and tractor primarilydepends on the level of the noise from the tractor (radios are anadditional source of noise). We recommend that the tractor isoperated with closed windows.
2.3 Instructions for fire protection
The harvested crop can easily ignite! To prevent fire:
remove crop remains and oil leaks.
If any machine parts run hot: find and remove cause.
Do not begin a journey with the machine attached unless themanually operated brake has been completely released.Otherwise there is danger of fire by brakes running hot (e. g.in the field).
Keep the electrical systems of tractor and baler and theexhaust system of the tractor in proper condition.
The existing wiring must not be used for any otherconsumers than those installed in the factory or approved bythe manufacturer. Overloading the electrical lines leads toexcessive heating.
Do not smoke in the vicinity of the machine.
Keep fire extinguisher within reach.

If any short-timemaintenance or assembly work is carried outwith the tail gate open, the tail gate must be hydraulicallysecured against lowering: use shut-off valve (on themaintenance platform). When the valve is shut off, the actuating
lever is at right angles to the flow direction (Figure 2).
In case of longer maintenance or assembly work with the tailgate open, the tail gate must (in addition to the hydraulicsafeguard) be mechanically secured against lowering - usingsuitable means.
After completion of any maintenance and/or assembly workreset the valve to its initial position (along flow direction, Figure3) and/or remove the mechanical safeguard.
2.5 Maintenance Platform and Ladder
Attention, danger of falling!
Never step on the maintenance platform [14] (Figure 4), whilethe machine is in motion. Before stepping on the maintenanceplatform: stop machine, switch-off power take-off shaft andtractor motor and wait for standstill of the machine.Climb and leave the maintenance platform exclusively via theladder [10]. Never step on the ladder when folded up alwaysfold down the ladder before using it.
(Figure 4) To climb the maintenance platform: fold down theladder [10].
(Figure 4) Before the machine can move on: fold up and lockthe ladder [10] again.
(Figure 4, Figure 5) For transportation the railing [15] isremoved from the maintenance platform in the factory andenclosed with the machine. The railing must be mounted againbefore commissioning of the machine:
Take the dismounted railing [15] out of the machine.
Mount the railing [15] to the maintenance platform using the6 enclosed screws [16] (Figure 5).

4.2.3 Adjusting the drive shaft
(Figure 20) Pay attention to maximum operating length Lmaxand minimum operating length Lmin! Aim at maximum
overlap possible.
a) Shortest operating length, i. e. complete overlap.
b) During normal operation, the overlap of the sliding tubesshould be a least 2/3 of the profile overlap LU.
c) For a short time, the drive shaft can be operated withthe length Lmax , i. e. the profile overlap is 1/3 LU.
If necessary: adjust length. Hold the drive shaft halves next
to each other in the shortest operating position and markthem. Shorten inner and outer tubes by equal amounts sothat a sliding travel of 40 mm is retained in the shortestoperating position.
Secure the protective tubes of the drive shaft by retainingchain against revolving.
Before the starting the drive shaft, check whether the lockshave properly engaged.
When driving through narrow bends ensure that the wideangle joint (on the tractor side) is not bent more thanpermitted by the manufacturer of the drive shaft.
Heed the operating instructions of the drive shaft'smanufacturer as well as national relevant signs with typeapproval for drive shaft protection.
Only the drive shafts prescribed by the manufacturer may beused!
Support drive shaft always with the drive shaft support whenmachine is uncoupled (Figure 22). In case of bottomcoupling swivel up the support accordingly.
Attention, danger of injury!
Protective tube and guard cone of the drive shaft, and thepower take-off shaft protection, must be fitted and be in proper

5 Twine tying*
5.1 Threading the twine
Attention, danger of injury!Prior to inserting of new spools of twine and threading thetwine: stop machine, switch-off power take-off shaft and tractormotor, take out ignition key and wait for standstill of themachine. Make the control powerless (disconnect electricalconnection to the tractor).
Note!Optimum results in production during use of our machinesdepend of multiple factors. Therefore:
The threaded twines must not contact each other or runcrosswise.
Use high-grade twines (recommendation: plastic twines).Place the twine spools upright side by side in the twine box.If the spools are inserted the wrong way round, the twine willtend to loop and break.
Heed and follow the instructions given in the operatinginstructions.
For working in extreme ambient conditions: request to ourcustomer service. Heed the technical data at the end of thisoperating instruction.
Twine A(Shown by continuous line in Figure 28 and Figure 29.)
Twine B(Shown by dotted - - - - - - line in Figure 28 and Figure 29.)
Twine A (Figure 28): Feed the beginning of the twine fromspool A1 upwards through the guide eye and then out of thetwine box. Knot end of twine of spool A1 with the beginningof the twine of spool A2. Important: The knot must be verysmall!
Twine B (Figure 28): Feed the beginning of the twine ofspool B1 upwards through the guide eye and then out of thetwine box. Knot end of twine of spool B1 with the beginning

5.2 Adjusting the twine brake
The twine brakes [1] (Figure 28) must hold the twines as taut aspossible for the twines to be tight around the bales.
(Figure 30) Adjust dimension "X" of the twine brake
according to the following table.
Basic settingLength "X" of the spring
(Figure 30)
Twine A 39 mm
Twine B 37 mm
Note! The permitted thread tension is exceeded when the twine
breaks in the vicinity of the guide rollers [8] (Figure 30).
The dimension "X" is measured between: washer bottomedge and the bottom surface of the cranked plate.

5.3 Setting the edge clearances
For lateral limitation of the twine wrapping at the ends of thebale:
adjust the left and right range spacer [1] (only the rightmachine side is shown in Figure 31 and Figure 32).
With very dry and brittle crop materials select the retainersin the middle of the baler.
5.4 Adjusting the wrapping distance
The distance between the wrappings is given by the diameterused for the variable diameter disc [9] (Figure 29). The smallerthe effective diameter of the disc, the greater the distancebetween the wrappings.
A lever [2] used to adjust the wrapping distance is located onthe far right-hand end (in travelling direction) of the binding bar[2] (Figure 31 and Figure 33).
Swivelling the lever towards the machine centre will movethe two halves of the variable diameter disc apart, reducethe effective diameter of the variable diameter disc andresult thus in a larger twine distance. Setting:
Position 1: maximum wrapping distancePosition 7: minimum wrapping distance

5.5 Edge wrapping adjustment
In order to ensure that the high density bales remain wellcompressed, the twine wrappings are automatically laid closertogether near the edge of bales.
In order to achieve this, the right-hand shuttle [4] presses thevariable diameter disc closer together when reaching the endzone. The working diameter of the variable diameter discincreases and the distance between wrappings is reducedtowards the edges.
A switching angle [3] (Figure 34) is installed in the right-handshuttle, which is attached by two screws in a unit with a set ofholes. Four different installation positions are available.
By displacing the angle towards the variable diameter disc, thevariable diameter disc is pressed closer together for the area ofthe edge wrappings. The effective diameter increases and more
edge wrappings are applied to the edge of the bale. Setting:
Displace switching angle (3) towards the variable diameterdisk: more end windings on the edge of the bale.
Or:
Displace switching angle (3) towards the machine centre:less end windings on the edge of the bale.

Using the scale (Figure 52) the net length (i.e. the number ofnet wraps around the bale) can be adjusted continuously:
Slacken the wing nut. Displace the wing nut in the slotted hole to adjust the desired
net length.
Retighten the wing nut.
Note!First select a setting in the middle of the slotted hole. To savenet material change the setting step by step towards ( ) forsubsequent bales.Do not use too little net material: The bale must still be heldtogether. For very smooth bales and high baling densities a
larger amount of net material must be adjusted.
Note!If the bale diameter changes the net length must be adjustedaccordingly.
6.3.2 E-LINK
Via the E-LINK control system the net length can be adjusted inincrements of 0.5 from 1.5 to 5 net layers (net layers are thenumber of net wraps around the bale).
Note!In case of E-LINK machines the wing nut must be installed inthe separate square hole of the scale (Figure 52) (not in theslotted hole).
