1.0 INTRODUCTION.
TELLEFSDAL A.S congratulates you with the choice of AUTO WRAP bale wrapping machine. We
are certain you will be satisfied with the machine, and that you will have the pleasure of your
investment for many years.
The AUTO WRAP bale wrapping machine has more features than any other bale wrapping machine
available. AUTO WRAP can pick up the bale, wrap and stack them without the operator leaving the
tractor cab. This system is protected by patent law's almost world wide.
AUTOWRAPishydraulicallydrivenbythetractorshydraulicsystem,andiscontrolledfromthetractor
cab by a remote control unit. The machine can either be mounted to three point linkage, front
mounted with quick-couplers to the tractors frontloader or on a wheel loader. Then it's possible to
stack the bales upon each other.
AUTO WRAP 1510 is designed to wrap bales of grass, hey or straw, with nominal diameter of 4-6 ft.
(120 -180 cm), and weights up to lbs. (1500kg).
The AUTO WRAP 1514 is essentially the same machine as the AUTO WRAP 1510, but with a
patented special mounting for the rollers so that square bales can be wrapped.
The AW 1514 can wrap both square and rectangular bales, from 60 x 60 to 120 x 120 x 150 cm.
It can take bales of up to 1,200 kg. It can also wrap round bales of up to ø1200 mm.
Both the AW 1510 and 1514 can also be supplied as TWIN models, i.e. the machines are
equipped with two film stretching units and two cutters. This gives the machines a significantly
increased capacity.
The machine is developed and has been improved since the beginning in 1986, and is now a very
reliable and safe machine with high security built in.
ThismanualismeanttoexplainhowAUTOWRAPisprepared,mounted,usedandhowitworks, and
shall together with the spare part's list be a reference for maintenance and troubleshooting. So take
good care of the books, they are a part of the machine.
Read carefully through this manual, and specially chapter 2.0, safety instructions, before starting the
machine, and follow the instructions thoroughly. If problems should occur, check with chapter 17.0,
and try to find out what is wrong. Ask your dealer for advice before you make the problem worse than
it is. See also chapter 19.0, conditions of warranty.

2.0 SAFETY PRECAUTIONS.
TELLEFSDAL A.S does not take the responsibility for damages that may occur on machine,
persons or other equipment, because of the machine NOT being used as described in this
manual, or because of the safety precautions NOT being followed.
2.1 SAFETY EQUIPMENT.
Before using the machine, make sure that all guards and covers are securely fitted. The machine
mustnot be operated if a function does not work as described later in this manual. (See chapter 2.5).
The Auto Wrap 1510 / 1514 / TWIN models are equipped with an "EMERGENCY STOP" on the
wrapping arm. This device stops all functions instantly, but is by definition not an emergency
stop, because it does not interrupt the feed. Nevertheless it has an equivalent function, so we
have decided to call it an EMERGENCY STOP in this book.
2.2 BECOME FAMILIAR WITH THE OPERATIONS OF THE MACHINE.
If you are unsure how to operate the machine properly, either use of or maintenance to your Auto
Wrap, please contact your Auto Wrap dealer.
2.3 ADJUSTMENTS' / MAINTENANCE.
Turnoff the tractor and discharge the oil pressure before performing any adjustment or maintenance
on the machine. Remember that a well maintained machine is a safe machine.
2.4 IMPORTANT!
MAKE ALWAYS SURE THAT NOBODY IS IN THE HAZARD
AREA OF THE WRAPPING ARM WHEN THE MACHINE IS IN USE.
THE MACHINE MUST NEVER BE OPERATED BY PERSONS WHOM DOES NOT KNOW ENOUGH
ABOUT HOW TO SAFELY OPERATE THE MACHINE, OR BY PERSONS UNDER 16 YEARS OF AGE.

* Emergency stop: see chapter 2.1

Fig. 2-2
2.5 DANGEROUS AREAS.
TELLEFSDAL A.S has given the safety to the operator the highest priority, but it is still impossible to
secure oneself of every danger area on the machine. Therefore we will now go through some of the
dangers that can occur when using the Auto Wrap balewrapper.
1. PUNCH OF THE WRAPPING ARM.
During the wrapping process the arm rotates with a speed of 20-27 revolutions per minute
around the bale. On the arm there is mounted a prestretcher unit with a plastic roll. The
speed on this can give a person serious injuries if one comes to close to the working area
of the wrapping arm. To reduce this danger we have mounted an emergency stop* device
on the wrapping arm, this stops all movement instantly when someone comes in the way of
it. It is very important that this protection always works and that it should not under any
circumstances be unconnected.
(See more about the emergency stop* in chapter 5.0).
2. SQUEEZE-DANGER BETWEEN THE MAIN FRAME AND THE WRAPPING ARM.
As earlier explained, we have a wrapping arm with a prestretcher and a plastic roll. Once
every time around this wrapping arm passes the main frame. Here there may occur a
squeeze danger if a person stands to close to the main frame when the wrapping arm
passes. The distance between the main frame and the wrapping arm is not large enough to
give place for a person. Between the prestretcher and the bottom frame there can also be
a squeeze danger.
3. SQUEEZE-DANGER BETWEEN THE STATIONARY AND THE WRAPPING ARM.
During the main wrapping process the wrapping arm moves around a stationary arm. Every
time the wrapping arm passes the stationary arm, there is a squeeze danger that can be
dangerous for the fingers. The distance between the stationary and the wrapping arm is
between 25-40 mm. (See fig. 2-2).

* Emergency stop: see chapter 2.1
6
Fig. 2-3 Fig. 2-4
4. SQUEEZE DANGER BETWEEN THE ROLLER ARMS AND THE MAIN FRAME.
When loading a bale, the roller arm moves in underneath the main frame. Here it can occur
asqueeze danger for feet and fingers. Keep therefore fingers and feet away from this area.
(See fig. 2-3).
5. SQUEEZE DANGER BETWEEN HINGE ON THE ROLLER ARMS AND MAIN FRAME.
When loading a bale there is also a squeeze danger between the hinge-ears on the roller
arms and the main frame, and between the width cylinders and the main frame. (Fig. 2-4).
Keep hands away from these areas. The squeeze danger between cylinders and frame is
reduced by the mounting of a rubber shield up front.
The machine must not be used if this cover is removed.

* Emergency stop: see chapter 2.1
7
Fig. 2-5 Fig. 2-6
6. SQUEEZE DANGER CAUSED BY PLASTIC AUTOMATION.
At the end of the wrapping process the plastic shall be perforated and held tight until the
start of the next wrapping process. When the cutter arm moves down to lock the plastic,
there can occur a squeeze danger between the cutter arm and the cutter holder. The cutter
bladethat perforates theplastic is verysharp, so keephands away fromthe cutter. (Seefig.
2-5).
Always put the security cover over the cutter blade when the machine is not in use.
7. SQUEEZE DANGER BETWEEN THE ROLLERS ON AUTO WRAP 1514 / TWIN.
When the rollers on the 1514 machine are moved all together, there is not enough space
for a person between the rollers. Here it can occur a squeeze danger, so make sure that
nobody is between the rollers when they are moved together. (See fig. 2-6).

* Emergency stop: see chapter 2.1

2.6 LOCKING THE WRAPPING ARM.
When the machine is not in use, make sure the locking bolt for the wrapping arm is mounted. If the
bolt is not mounted, the wrapping arm and/or the machine could be damaged during transport. (See
fig. 2-7). For TWIN machines, see also section 2.10.
2.7 THREE POINT MOUNTING.
When the machine is mounted in the three point linkage, make sure that the lifting arms are tightend
up so there is no sideways movement.
2.8 FRONT MOUNTING.
Ifthemachineismountedonthefrontloadertheremustbeacounterweightinthethreepointlinkage.
It must be large enough to give the tractor good stability.
Connecting heavy working implements often has an overall negative effect on the tractor's
driving and braking capacity.
2.9 TRANSPORTING.
When transported on a public road there are certain safety measures that must be taken:
1. Move the wrapping arm in under the davit in the transport position by pressing "STOP"(9)
and keeping it pressed in.
2. Forlockinganddisengagingthewrappingarmduringtransportation,ensurethatthelocking
bolt for the wrapping arm is fitted. (See section 2.6 and fig. 2-7.)
3. Move the main rollers completely together.
4. Always transport the machine in the lowest possible position.
5. Makesure that the machine do not cover the tractors lights. If necessary, mount extra lights.
6. Make sure that at least 20% of the tractor's total weight is on the steering wheels.
7. If the machine is front-mounted, it's necessary to balance the weight with a counterweight
mounted to the three-point linkage.

2.10 SPECIAL INSTRUCTIONS FOR AUTO WRAP 1510 / 1514 TWIN
These machines must be prepared for transport in a slightly different way:
1. Move the main wrapping arm in under the davit in the transport position by pressing
"STOP" (9) and keeping it pressed in.
2. Forlockinganddisengagingthewrappingarmduringtransportation,ensurethatthelocking
bolt for the wrapping arm is fitted. (See section 2.6 and fig. 2-7.)
3. Loosen the fixing screws for the locking plate which secures the second wrapping arm in
the working position. Then swing the arm in towards the davit. (See fig. 2.8.)
4. To reduce the transport width of the TWIN machines, at the same time preventing the
secondaryarmfromaccidentallyswingingouttothesideduringtransportation(seefig.2.9),
each cutting beam is put in the transport position by holding the beam by the edge and
lifting it upwards and inwards by hand. Using a special grooved slot at the back end of the
mounting point, the cutting beam locks automatically in the raised transport position when
the beam is dropped to its lower position once more at the back. (See fig. 2.10.)(See also
sections 3 to 8 for the standard machines)

3.0 GENERAL INFORMATION ON BALE WRAPPING.
3.1 THE PRINCIPLE.
The advantages of round bale ensilage are many, and include fewer feed units, a flexible harvesting
system, large capacity and the possibility of selling feed units.
In principle, the same fermentation processes occur whether the fodder is placed in a silo or pressed
into bales and packed in plastic, i.e. lactic acid fermentation in anaerobic conditions. The oxygen in
the bale must be exhausted before fermentation begins.
The grass should be dried to approximately 30-40% solid content. The solid content can be
determined by twisting the grass by hand. If drops of liquid are forced out of the grass, the solid
content is less than 25%. Low solid content, (wet grass), can lead to increased butyric acid
fermentation if preservatives are not added to the grass. If the solid content is too high, (over 50%),
normal fermentation will not take place and there will be enough oxygen in the bale to produce mould
fungus.
3.2 THE BALE PRESS.
Itisvitalthatthebalepressproducescompact,well-formedbales,asmisshapenbalescanbedifficult
to pack. Pressing will also often take longer, thereby increasing the amount of plastic used.
3.3 DIFFICULT BALES.
Whenamisshapenbaleispacked,itwillhaveatendencytomoveoutwardsorinwardsontherollers.
If the bale begins to move outwards, the machine must be lifted slightly at the rear edge to get the
baleto rest againstthe support rollerson the mainframe. It cantherefore be usefulto use ahydraulic
top stay to make this adjustment easier. (See chapter 4.2).
If the support rollers almost disappear into the bale the machine should be pressed down slightly at
the rear edge in order to remove the bale from the machine. The plastic can be damaged when
friction against the rollers increases. Best results are achieved when the bale rolls easily against the
support rollers all the time.
If the bale to be packed is conical you must ensure that the sharp end is pointed at the tractor. It will
then be easier to get the bale to lie correctly during packing. It is easy for such a bale to "turn" forward
in the direction in which it is pointing, and therefore lie against the support rollers. If the bale is lying
on a slope it must be picked up from the lower side. A hydraulic top stay will again be advantageous.
3.4 TYPES OF PLASTIC.
Agood type of plastic with good adhesive properties, and which is recommended for bale wrapping,
must be used. The thickness of the plastic foil should be at least 25 µ. (25/1,000 mm). In order that
theplastictightenssufficientlyaroundthebale,itisstretchedbeforebeingwrapped,soitissomewhat
thinner when it is put on the bale. With short-term storage, (up to eight weeks), it is recommended
that bales have a minimum of four layers of plastic at the thinnest points, with at least 52-53%
overlap.
For long-term storage, or when the grass is wet when it is packed, the bale should have 90-100 µ
plastic, (6 layers), and the same amount of overlap. If thinner plastic is used, more layers should be
applied. If it is very hot the plastic will be stretched further, and more layers should be applied. It is
better to have slightly too much than too little plastic on the bale.
From experience, light plastic produces slightly lower temperatures within the bale, and tends to
improve feed quality.
3.5 STORAGE LOCATION.
Care should be taken in finding a suitable location for the storage of bales. The storage location
should preferably be prepared before the bales are laid out. An elevation close to well-drained roads
is recommended. If the wrapped bales are simply placed on stubble there is a danger of the plastic
being pierced. A tarpaulin or a thin layer of sand should therefore be laid where the bales are to be
stored over the winter.
Bales should be stored in the shade as far as possible. This reduces the danger of air leakage in the
bales.Abalewhichisstoredinsunlightandwhichthereforeundergoesgreaterswingsintemperature
"pumps in" a great deal of air in comparison to a bale which is stored in the shade. According to

* Emergency stop: see chapter 2.1
11
"Teknik for Lantbruket" [Technology for Agriculture] in Sweden, a bale which is stored in the shade
has only 40% of the air leakage of a bale which is stored in sunlight.
3.6 STACKING / PROTECTION.
If bales are hard and well formed, they can be stacked vertically, but loose and misshapen bales with
low solid content should not be stacked higher than one layer, as this could easily cause deformity
and the danger of runoff will be increased.
Bales can also be stored on their sides. The layer of plastic is thicker here, providing greater
protection against piercing.
Bales should be covered with a tarpaulin or a fine-mesh net to protect against birds and small
rodents. If the plastic is pierced, it must be sealed with weatherproof, hard-wearing tape, preferably
under the outermost layer of plastic. Ensure that the hole is adequately sealed.
3.7 The best wrapping results are obtained by...
1. ...harvesting the grass early.
2. ...drying it out to 30-40% solid content. If there is a danger of rain, press and pack the
grass anyway.
3. ...taking care not to mix any earth in with the grass.
4. ...using a press that produces even, firm bales.
Bales 1.2 m in width and with a diameter of 1.2-1.5 m are the preferred sizes.
5. ...packing the bales soon after pressing, never later than two hours afterwards.
6. ...using a good type of plastic and six layers of plastic. This removes the need to use
preservatives.
7. ...storing bales in the shade to reduce the danger of air leakage.

Fig. 4-1 Fig. 4-2
4.0 SETTING UP / MOUNTING OF THE MACHINE.
Be careful! There is a danger of being crushed when working implements are fitted and
connected. Carry out the fitting procedures slowly and carefully, and use separate and
approved lifting equipment to make the work easier. See section 2 on safety regulations and
pay attention to the various safety decals displayed on different parts of the bale wrapper.
4.1 HINGED TOWER.
Because of the freighting of the machine, AUTO WRAP 1500 / 1514 is sometimes delivered with the
tower hinged down. Before use, the tower must be lifted up and fastened with 5 pcs. 16mm bolts.
Figure 4-1 shows the machine at delivery.
Remove all packing strips and lift up the tower. Use a crane or the front-loader on the tractor and lift
in the liftingpoint at the top of the machine. (See arrow).Then mount the 5 pcs. M16 x 55 bolts with
washers and lock nuts.
Securing the davit on TWIN machines is slightly more complicated because of the bracing clamps
which have to be fitted on each side of the davit. Fit the lower fixing screws for the clamps (8 screws
size 12 x 140).
SCREW IN SECURELY and after several hours' use tighten all the screws once again.

* Emergency stop: see chapter 2.1
13
Fig. 4-5Fig. 4-4
4.2 MOUNTING OF PRESTRETCHER.
It is to be fastened with the same 2 bolts that the locking bracket is fastened with. (You don't have to
remove the locking bracket). Remove the nuts and mount the prestretcher and the wrapping arm.
The same procedure is followed for fitting the brace on TWIN machines.
4.3 MOUNTING OF EMERGENCY STOP* ARM.
The machine is equipped with an emergency stop*, and the releasing arm has to be mounted.
Put the arm into the bracket and mount the hinge bolt. Replace the washers and tighten the locking
nuts. (See fig. 4-4).
The return spring is to be fastened between the eye bolt on the arm and the eye bolt on the bracket.
(See chap. 9-1 in the spare parts list for details).
TWIN machines have emergency stop arms on each brace and are fitted in the same way as they
are on standard machines.

* Emergency stop: see chapter 2.1
14
Fig. 4-6 Fig. 4-7
4.4 MOUNTING OF RELIEF ROLLER.
At last the relief roller under the machine has to be mounted. When the machine has been mounted
on the tractor, lift it clear of the ground, and secure it from falling down before working underneath
themachine. Mount therelief roller with2 pcs. M12x 120 bolts,washers and locknuts. (See fig.4-6).
The off-loading roller can be fitted at three different heights. On the Auto Wrap 1510 it is fitted at the
top position as illustrated on the right in fig. 4-7. (The locating bracket must be turned 180E)
On the Auto Wrap 1514 it is fitted at the centre position if rectangular bales (for example, 90 x 120
cm) are to be wrapped. For bales which are squarer than this, it is fitted at the lower position.

* Emergency stop: see chapter 2.1
15
Fig. 4-8 Fig. 4-9
4.5 THREE POINT LINKAGE.
AUTO WRAP 1500 / 1504 /TWIN is intended for rear mounting to the three point linkage, category
2. (Fig. 4-8). With considering of transportation are not the three point brackets mounted on the
machinewhenitleavesthefactory.(Seesparepartslistchapter2-1formoredetails).Whenattached
to three point linkage, make sure the machine is level across the tractor. Tight up and lock the lifting
arms so there is no sideways movement.
4.6 TOP LINK.
Adjust the top link of the tractor so that the machine is level with the ground. It is recommended to
use a hydraulic top link, as this makes it easy to adjust the angle of the machine.
During the wrapping process it is recommended to tilt the machine towards the tractor, as this will
prevent the bale from falling off the rollers. (See fig. 4-9).
4.7 FRONT MOUNTING.
Asextraequipmentthemachinecanbeequippedwithquick-couplersforfrontloaderorwheelloader.
(See spare parts list chapter 2-2 for what types of quick couplers there are).
You also need longer hydraulic hoses. (See spare parts list chapter 4-2 for more details).

4.8 ELECTRIC CONNECTION.
The electric supply for the machine's remote control and electro-hydraulic components must come
directly from the tractors' 12 volt battery.
The electric wires from the battery must have an area measurement of min. 2,5 mm2.
Connection to other contacts on the tractor can cause risk of misfunctions, and is not to recommend.
Tosecurethe electric systemagainst short-circuits thereis an 8Afuse on theplus-leader, near tothe

REMOTE CONTROL.
The control unit should be attached to a suitable place in the tractor cab, next to the front loader's
operating lever if the machine is front mounted.
THE REMOTE CONTROL UNIT IS NOT SHOCK-PROOF. MAKE SURE THAT IT IS FASTENED
TO A SOFT PAD THAT SECURES A NON-VIBRATING FOUNDATION.
4.9 HYDRAULIC CONNECTION.
The hydraulic hoses between machine and tractor are equipped with 1/2" ISO male quick-couplers.
Discharge the oil pressure before you connect the oil hoses. Use the tractors' hydraulic lever.
To make sure that the balewrapper works properly, the tractors' oil pressure has to be at least 180
bar. The oil flow should be 15 - 25 litres per minute.
The counter pressure on the return must be as low as possible, and not exceed 10 bar. This should
bemeasuredwithagauge.Itisrecommendedtouseonesingle-workinghydraulicoutletandarrange
a free return circuit to the oil tank. If you are unsure of what oil pressure the tractor gives, or what oil
pressurethebalewrapperreceives,pleasecontactyourmachinerydealer.Generallyalltractorshave
got some counter-pressure in their hydraulic return systems. Some tractors have more than others.
Hose with red cap shall be connected to pressure, (P), and hose with blue cap to the return.

4.10 HYDRAULIC SYSTEM WITH OPEN OR CLOSED CENTRE (See also section 14.1.)
The selective control valve (V1) allows you to choose between an open and closed centre for the
hydraulic system. Most tractors have a hydraulic pump which produces a fixed volume of oil per
revolution (open centre). The valve must then be in the open position. (See fig. 4-12.)
Some other tractors (such as John Deere) have oil pumps with variable volume per revolution
(closed centre). The valve must then be in the closed position. (See fig. 4-13.)

* Emergency stop: see chapter 2.1
18
Fig. 4-14
4.11 CHECK LIST.
Before using the machine it is recommended to follow this check list:
1. Make it a habit to discharge the oil-pressure before connection or disconnection of the
hydraulic hoses. (Use the tractors hydraulic control lever).
2. Return-oil should be led as directly to the tank as possible. Beware that if the counter
pressure is too high, the security valve on the main block will release some oil. (See chapter
14.3).
3. Hose with BLUE CAP = RETURN OIL.
4. Hose with RED CAP = PRESSURE.
5. Tie up loose hoses so that no squeeze damages may occur.
6. Remove the locking bolt that holds the wrapping arm to the frame during transport.(Fig. 4-14
and Fig. 2-7)If necessary unfold and lock the extra wrapping arm on a TWIN machine. Do
the same with the cutter beams. (See section 2.10 and figs. 2.7, 2.8, 2.9 and 2.10.)
7. Makesure that the plug-in contact from the remote control is connected to the socket on the
machine.
8. Start the tractor and try out the functions. A bale is not required for this test.
9. Check all connections, hoses and couplings. If there is any oil-leakage, it should be rectified
immediately.
If any problems should occur, it is most likely that the failure is in the quick-couplers on the
tractors pressure and return-connections.
They can be very narrow and work badly after some years.
Make sure that both the male and the female-couplers opens properly for the oil flow. Check
them carefully. The best thing to do is to exchange the quick-coupling on the return side and arrange
a "free return".
Your AUTO WRAP bale wrapper has been tested in practical operation in approx. 2 hours at
the factory.

5.1 Themachine is equippedwith a safetyguard on thewrapping arm, andits operation mustbe tested
before work itself is started.
5.2 The safety guard is designed to stop the wrapping arm injuring operators or objects either when
starting up or when wrapping bales.
5.3 The emergency stop* is constructed with a "positive" connection, i.e. it has to be in full order before
the machine can be started.
5.4 This consists of a release guard which is connected by a wire to the lever arm, and this activates
a small electrical switch via a sliding contact (14, fig. 5-2).
If the electrical circuit is broken, the hydraulic oil flow is cut off and all functions stop immediately.
This is indicated on the control box display by three illuminated dots. (See section 7.1.)
5.5 When this function shall be tested, you start the wrapping arm. Hold out an arm or any obstacle. The
wrapping arm shall now stop before it hits the arm.

position. If "STOP" (9) is pressed before "START"(8),the wrapping continues from the point in the
program at which the emergency stop was activated. If, on the other hand, "STOP"(9) is pressed
before "ZERO"(3),then the wrapping sequence starts from the beginning again. (See further in
section 7.9.)

6.6 HEIGHT ADJUSTMENT OF PRESTRETCHER / PLASTIC FILM.
Theplastic film shallhit at themiddle of thebale wrapped, andtherefore it canbe necessary toadjust
the height of the prestretcher. (See more about this in chapter 10.2).
If you use 500 mm plastic on a 750 mm prestrecher, then you can use the two distance sleeves to
adjustthe height on the plastic roll. There can be mounted one sleeve on each side of the plastic roll,
or both sleeves can be mounted above or below.
