TANCO AUTOWRAP LTD. congratulates you with the choice of an AUTOWRAP 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 TANCO AUTOWRAP bale wrapping machine has more features than any other bale wrapping
machine available. TANCO AUTOWRAP can pick up the bale, wrap and stack them without the
operator leaving the tractor cab. This system is protected by patent TANCO AUTOWRAP Ltd almost
world wide.
TANCO AUTOWRAP is hydraulically driven by the tractors hydraulic system, and is controlled from the
tractor cab by a remote control unit. The machine can either be mounted to three point linkage, front
mounted with optional attachment brackets to the tractors front-loader or on a wheel loader. Then it's
possible to stack the bales upon each other.
TANCO AUTOWRAP 1510 is designed to wrap bales of grass, hay or straw, with nominal diameter of 4-
6 ft. (120 -180 cm), and weights up to lbs. (1500kg).

Operator’s manual
The TANCO AUTOWRAP 1514 is essentially the same machine as the TANCO AUTOWRAP 1510, but
with a patented special mounting for the rollers so that square bales can be wrapped.
The TANCO AUTOWRAP 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 TANCO AUTOWRAP 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.
This manual is meant to explain how TANCO AUTOWRAP is prepared, mounted, used and how it
works, 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.

2.0 SAFETY PRECAUTIONS.
TANCO AUTOWRAP Ltd 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
must not 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
AutoWrap, please contact your AutoWrap dealer.
2.3 ADJUSTMENTS’ / MAINTENANCE.
Turn off 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!
ALWAYS MAKE SURE THAT NOBODY IS INSIDE
THE MACHINE’S WORKING AREA WHEN IT’S IN USE.
SAFETY DISTANCE IS 5 METRES
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.

2.5 DANGEROUS AREAS.
TANCO AUTOWRAP LTD. 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 TANCO AUTOWRAP Ltd bale
wrapper
.
1. IMPACT 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 a
Dispenser unit with a plastic roll mounted. The
speed of 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 disconnected.
(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 dispenser and a plastic roll. Once
every time around this wrapping arm passes the main frame. There is 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 for a person. Between the
pre-stretcher 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).
4. SQUEEZE DANGER BETWEEN THE ROLLER ARMS AND THE MAIN FRAME.
When loading a bale, the roller arm moves in underneath the main frame. There is a squeeze
danger for feet and fingers. Keep therefore fingers and feet away from this area.

8
Tanco Autowrap 1514-1510
Operator’s manual
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-points 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.
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
blade that perforates the plastic is very sharp, so keep hands away from the cutter. (See fig.
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).

9
Tanco Autowrap 1514-1510
Operator’s manual
2.6 LOCKING THE WRAPPING ARM.
When the machine is not in use, make sure the locking bracket 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 stabilizing links are
tightened-up so there is no sideways movement.
2.8 FRONT MOUNTING.
Ensure that the machine you intend use the machine on has sufficient capacity to lift the
wrapper with a bale loaded.
If the machine is mounted on the front loader there must be a counterweight in the three point
linkage. 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
"WRAP SLOW” in manual mode and keeping it pressed in.
2. For locking and disengaging the wrapping arm during transportation, ensure that the
locking bracket 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. Make sure 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.

10
Tanco Autowrap 1514-1510
Operator’s manual
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
"Wrap slow" and keeping it pressed in.
2. For locking and disengaging the wrapping arm
during transportation, ensure that the locking 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
secondary arm from accidentally swinging out to the side during transportation (see fig.
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)

Tanco Autowrap 1514-1510
Operator’s manual
3.0 GENERAL INFORMATION ON BALE WRAPPING.
3.1 THE PRINCIPLE.
The advantages of round/square bale silage 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 3040% 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 t9o 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 BALER.
It is vital that the baler produces compact, well-formed bales, as misshapen bales can be difficult
to wrap. Baling will also often take longer, thereby increasing the amount of plastic used.
3.3 TYPES OF PLASTIC.
A good 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 p. (25/1,000 mm).
In order that the plastic tightens sufficiently around the bale, it is stretched before being wrapped,
so it is somewhat 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 wrapped, the bale should have 90-1 00
p 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.
3.4 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. A bale which is stored in sunlight and which therefore undergoes greater swings in
temperature “pumps ins’ a great deal of air in comparison to a bale which is stored in the shade.
According to ~‘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.
3.5 STACKING I 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.

12
Tanco Autowrap 1514-1510
Operator’s manual
3.6 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, bale and wrap the
grass anyway.
3. Taking care not to mix any earth in with the grass.
4. Using a baler which produces even, firm bales.
5. Wrapping the bales soon after baling, 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.
4.0 SETTING UP / MOUNTING OF THE MACHINE.
Fig 4.1 Fig 4.2
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 10 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 lifting point at the top of the machine. (See arrow).Then mount the 5 pcs. M16 x 55
bolts with washers and lock nuts.
SCREW IN SECURELY and after several hours' use tighten all the screws once again.

13
Tanco Autowrap 1514-1510
Operator’s manual
4.2 MOUNTING OF DISPENSERS
The dispensers are attached to the Wrap arm using 2 M12 bolts at a fixed height.
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.
4.4 MOUNTING OF SUPPORT ROLLER.
Lastly, the support 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 the machine. Mount the relief roller with 2 pcs. M12 x 120 bolts, washers and lock
nuts. (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 180Ε)
On the Auto Wrap 1514 it is fitted at the center position if rectangular bales (for example, 90 x
120cm) are to be wrapped. For bales which are larger than this, it is fitted at the lower position.

14
Tanco Autowrap 1514-1510
Operator’s manual
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). For transportation the three point linkage brackets are not always
mounted on the machine when it leaves the factory. (See spare parts list chapter 2-1 for more
details).
When attached 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.
As extra equipment the machine can be equipped with attachment brackets for front loader or
wheel loader. (See spare parts list chapter 2-2 for what types of brackets there are).
You also need longer hydraulic hoses. (See spare parts list chapter 4-2 for more details).
When front-mounted there must be mounted a large enough counterweight in the three point
linkage, this is to secure the tractors stability.

15
Tanco Autowrap 1514-1510
Operator’s manual
4.8 ELECTRIC CONNECTION.
The electric supply for the machine's control unit 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 of other contacts on the tractor can cause risk of malfunction, and is not
recommended.
BROWN LEADER GOES TO BATTERY PLUS POLE
BLUE LEADER GOES TO BATTERY MINUS POLE
4.9 CONTROL UNIT
The control unit consists of the emergency stop button, a communication cable, and a power
cable. The control unit should be attached to a suitable place in the tractor cab, using the
supplied suction cup.
The control unit is supplied with: Battery power cable (we recommend direct
connection to the tractor’s battery), suction cup and control unit mounting
bracket. The mounting bracket should be mounted on the back of the controller
in such a way that the suction cup is directly behind the push buttons.
IMPORTANT!
When connecting the control unit to the machine, always ensure that the
communication cable cannot get damaged by the 3-point linkage or dragging
along the ground, by tying slack cable inside the cab.
Fig.: 4-10

16
Tanco Autowrap 1514-1510
Operator’s manual
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. The tractors' hydraulic
lever must be lock open when running. To make sure that the bale wrapper works properly, the
tractors' oil pressure has to be at least 180bar. The oil flow should be 15 - 25 liters per minute.
The return pressure on the return must be as low as possible, and not exceed 10 bar. This
should be measured with a gauge. It is recommended to use one single-acting hydraulic outlet
and arrange a free return circuit to the oil tank. If you are unsure of what oil pressure the tractor
gives, or what oil pressure the bale wrapper receives, please contact your machinery dealer.
Generally all tractors have 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. (T). (See fig. 4-11).
4.10 OPEN and CLOSED CENTER and LS HYDRAULIC SYSTEM.
The 1510/14 EH hydraulic system can be set up for tractors with open or closed
center hydraulics
Open Centre Hydraulics
Most tractors have a hydraulic system that gives a continuous output which
flows through the valve on the machine and back to tank when no function is
operating. (Open center).
TANCO AUTOWRAP 1510/14 EH is set-up for open centre on leaving the
factory.
Close Centre Hydraulics
Some tractors, (like John Deere), have a hydraulic system that require the
valve on the machine to allow no flow when no function is operating (Closed
center). The hydraulic valve can easily be configured to operate in this way.
Simply push and twist the manual override on the master valve and close fully
valve V2. (see fig 4.12)

17
Tanco Autowrap 1514-1510
Operator’s manual
Master valve
V2 Fig. 4.12
LS Hydraulics
Many modern tractors have a “Load Sensing” (LS) hydraulic system. This is
most efficient as the pump remains on standby, pumping no oil until it gets a
signal from the machine. It is possible to run this machine on a load sensing
tractor with the standard valve. Configure the valve for open centre and if
possible adjust the flow from the tractor to give ~30 l/min. This however means
that that tractor is constantly pumping and you do not get the benefit of the
efficiency of your load-sensing pump.
Thus Tanco Autowrap strongly recommend that if you are running the machine
on tractor with LS hydraulics you should fit load sensing feed back line from the
entry block (1/4” Hose) to the tractor from the LS entry port on the block.
Through this a Load sensing signal is transmitted in the form of hydraulic
pressure via a hose for the LS port on the entry block to the LS connection on
the tractor. With the line fitted configure the valve for closed centre as above.
Note that the LS entry block can be configured also to run on any other

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
return line
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. Make sure that the plug-in contact from the control unit 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.
The nipples of these connectors get worn and cause pressure build up which causes
extra heat.
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.
NOTE: The return line is fitted with a non-return valve which prevents oil flowing through the
system if the tractors spool valve is pulled in the wrong direction.

5.0 EMERGENCY STOP.
5.1 The machine is equipped with a safety guard on the wrapping arm, and its operation must be
tested before using the machine.
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.
An Error signal is indicated on the control box display. (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.
5.6 To restart the machine the obstacle must be removed and the safety guard must return to its
original position. Reset the controller by pressing and releasing the Red “E-Stop" button on the
controller. The wrap cycle can then be resumed by pressing the resume cycle switch. (See
further in section 8.0.)

6.0 FITTING ROLL OF FILM
6.1 When loading a plastic roll, first ensure the top cone (2) is pushed up to latched position, then
push back the Stretch rollers (3) until held in position by locking catch (4). .
6.2 Place the Roll on the Bottom Cone and release the top latch (1).
6.3 Pull the film between the rollers on the pre-stretcher in the direction of the arrow. (See fig. 5-2)
(See also the sticker on the dispenser).
6.4 Release the locking catch and allow the rollers to lie against the roll of film. Pull the film from the
roll and tie it to the bale.
6.5 HEIGHT ADJUSTMENT OF PRE-STRETCHER I PLASTIC FILM.
The plastic film should hit the bale in the middle. As the Dispenser is at a fixed height it is
necessary to adjust the Roller arm stops. i.e if the bale is too low, adjust the stops so that the
rollers close more, thus raising the bale and vice versa. See section 10.3.
If you use 500 mm plastic on a 750 mm dispenser, which is recommended for wrapping smaller
square bales, you need to use the “500 mm film adaptor” (see spare parts book).
