Page 3: Introduction
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).
Page 4: Safety Precautions
(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.
Page 5 Fig. 2-2 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.
Page 6 Fig. 2-3 Fig. 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. Here it can occur a squeeze danger for feet and fingers. Keep therefore fingers and feet away from this area. (See fig.
Page 7 Fig. 2-5 Fig. 2-6 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.
Page 8 Locking bolt off Locking bolt on Fig. 2-7a Fig.2-7b 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.
Page 9 Fig. 2-8 2.10 SPECIAL INSTRUCTIONS FOR AUTO WRAP 1510 / 1514 TWIN These machines must be prepared for transport in a slightly different way: Move the main wrapping arm in under the davit in the transport position by pressing "STOP" (9) and keeping it pressed in.
Page 10: General Information On Bale Wrapping
GENERAL INFORMATION ON BALE WRAPPING. 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.
Page 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. 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.
Page 12: Setting Up / Mounting Of The Machine
Fig. 4-1 Fig. 4-2 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.
Page 13 Fig. 4-4 Fig. 4-5 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.
Page 14 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.
Page 15 Fig. 4-8 Fig. 4-9 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 machine when it leaves the factory.
Page 16 Fig. 4-10 Fig. 4-11 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 mm Connection to other contacts on the tractor can cause risk of misfunctions, and is not to recommend.
Page 17 Fig. 4-12 Fig. 4-13 HYDRAULIC SYSTEM WITH OPEN OR CLOSED CENTRE (See also section 14.1.) 4.10 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).
Page 18 Fig. 4-14 4.11 CHECK LIST. Before using the machine it is recommended to follow this check list: Make it a habit to discharge the oil-pressure before connection or disconnection of the hydraulic hoses. (Use the tractors hydraulic control lever). 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.
Page 19: Emergency Stop
Fig. 5-1 Fig. 5-2 EMERGENCY STOP. The machine is equipped with a safety guard on the wrapping arm, and its operation must be tested before work itself is started. The safety guard is designed to stop the wrapping arm injuring operators or objects either when starting up or when wrapping bales.
Page 20: Mounting Of Plastic Film
Fig. 6-1 Fig. 6-2 MOUNTING OF PLASTIC FILM. When the plastic roll shall be mounted, you have to hold the prestretcher-rollers aside. Push the rollers to the side and hold inn place with each of the locking springs. (See fig. 6-1). Place a reel of film on to the prestretcher's lower holding axle and put on the springloaded lock.

Page 25: Speed Setting Of The Wrapping Arm
Fig. 8-1 SPEED-SETTING OF THE WRAPPING ARM. Start the tractor, let it run at approx. 1000 revolutions per min. lift the machin clear off the ground. The oil flow to the packing machine is adjusted with the use of two control valves which are placed on the valve block situated behind the machines "neck".[see fig.
Page 26: Adjusting The Overlap
Fig. 9-1 Fig. 9-2 ADJUSTING THE OVERLAP. WRAPPING ARM SPEED. Load a bale on to the machine. To be able to adjust correct overlap, you have to leave the tractor cab while wrapping. Check that the wrapping arm has a speed of approx. 22 revolutions per minute. If not, adjust this by turning the control valve for wrapping arm speed.
Page 27: Operation Instruction
Fig. 10-2 10.0 OPERATION INSTRUCTION. We shall now go through a complete wrapping process, from loading to storage place, and explain the practical use of Auto Wrap 1510 / 1514 / TWIN. 10.1 LOADING Find a bale you wish to wrap. Increase the opening between the bearer-rollers as much as possible.
Page 28 Fig. 10-3 Fig. 10-4 10.2 HEIGHT ADJUSTMENT OF PRESTRETCHER. The prestretcher can be placed in two different positions. It is fastened with two bolts. The prestretcher has to be adjusted so that the plastic film is always hitting the middle of the bale. If you use a 500 mm film on a 750 mm prestretcher, the height of the film roll can also be adjusted with the two distance sleeves.
Page 29 Fig.10-5 10.4 WRAPPING SQUARE BALES. (Auto Wrap 1514 / TWIN). When loading small square bales it is important to lower the rollers as close to the ground as possible. This to make all four rollers to get a grip on the side of the bale. If two of the rollers come over the bale, the machine will not be able to load it.
Page 30 10.8 STOP. When the required number of revolutions is obtained, push the (9) STOP-button. The wrapping arm will now rotate 1-2 revolutions, the cutter moves up, the arm speed is reduced and it stops at the right place for next wrapping cycles. Then the cutter closes automatically, and the film is held tight in the U-formed slot and perforated.
Page 31 11.0 SPECIAL OPERATING INSTRUCTIONS FOR THE TWIN MACHINES The Auto Wrap 1510/1514 can, as described earlier, also be supplied with a double set of wrapping arms, film stretchers and cutters. This significantly increases the machine's capacity. This machine is essentially the same as a standard machine, apart from a stronger davit and an extra valve block for the wrapping arm motor which reverses the wrapping arm after the wrapping sequence is completed.
Page 32: Periodic Maintenance
12.0 PERIODIC MAINTENANCE. 12.1 BEARINGS. All ball-bearings are packed with grease, and do not need any more maintenance. 12.2 PRESTRETCHER. If the machine is in daily use, the guiding sleeves at the prestretcher should be oiled once a week or when needed.
Page 33 12.10 SQUARE-BALE UNIT (AUTO WRAP 1514/1514 TWIN.) After a period of wrapping, grass will collect around the flanged bearings on the square-bale unit. (Position 16, section 6-5 in the spare parts list.) When this becomes wet, acids can form in the grass which can damage the bearings.
Page 34: Electric Circuit
Fig. 13-1 13.0 ELECTRIC CIRCUIT. 13.1 COUPLE FORM. The electric system consists of a remote control unit with supply line, control cable, (14-lead), with plug in both ends, and distributing lines to the different magnet valves and switches on the machine. (See fig.
Page 35 13.2 SUPPLY OF EL-POWER. The electric circuit must only be connected to 12 volt DC. Connect directly to the tractor battery, to avoid any loss of power. The fuse on the plus-leader must not be more than 10A. See chap. 4.8 and 4.11.7 about connection and setting up of the machine. 13.3 DESCRIPTION OF THE SYSTEM.
Page 36 Accumulator. 14.0 HYDRAULICS. The AUTO WRAP 1510 / 1514 / TWIN machines are driven by the tractor's hydraulic system. The machine's hydraulic installation is easy to change from an open centre to a closed centre hydraulic system. (See section 4.10).
Page 37 Fig. 14-1 14.1 FILTER BLOCK This block contains the oil filter, the selector valve for open or closed centre, the circulation valve, safety valves and volume-regulating valve. Selector valve for open/closed centre (CP 620-1.) Open centre hydraulics Most tractors have an oil pump which produces a fixed volume per revolution. For these tractors the selector valve must be in the open position.
Page 38 Check valve (VRC 6.) This prevents oil from flowing to the circulation valve in closed centre hydraulics. Regulator for V6 (CP 610-2.) Used to adjust the volume of oil that flows into the volume-control valve, which in turn regulates the amount of oil that flows into the control block.
Page 39 Fig. 14-2 14.2 CONTROL BLOCK The control block contains the five LC valves that control the main functions of the machine. They do not have V numbers, but have the same number as the electric cables to which they are connected.
Page 40 Fig. 14-3 14.3 ADJUSTING BLOCK This contains the adjusting valves for roller speed and wrapping arm speed, together with the two-stage start valve. Two-stage valve (Electric cable no. 6.) The speed is divided into two stages in order to make the wrapping arm start and stop smoothly.
Page 41 Fig. 14-4 Fig. 14-5 14.4 WRAPPING ARM BLOCK The wrapping arm block is fitted on the wrapping arm motor, and contains 4 valves. (On TWIN machines there is an additional electro-magnetic reversing valve, V35, fig. 14-6). When the wrapping arm starts the oil pressure releases the brake. When the brake is operated there is however a need for a slight delay here so as to prevent the wrapping arm stopping too abruptly.
Page 42 Fig. 14-6 Fig. 14-7 14.5 COLLECTING BLOCK (See fig. 14-7.) The collecting block contains all the valves which control and regulate the various functions concerned with loading and off-loading the bales. Selector valve (CP 520-1.) (Electric cable no. 11.) When the width between the rollers is reduced (while loading) and they reach the position at which the switch on the left bearer arm has been adjusted to trip (see section 10.1), this valve will then be activated.
Page 43 Fig. 14-8 Pilot controlled check valve (CP 450-2.) This lets the oil flow past during loading. It is opened by the force of the oil pressure flowing to the minus side of the width cylinder. Brake valve for the roller motors (CP 440-1.) This regulates the oil flow through the roller motors.
Page 44: Check Points Before Trouble Shooting
15.0 CHECK POINTS BEFORE TROUBLE SHOOTING. In this chapter we have some general check points that have to be examined first if something is wrong with the machine. In chapter 17.0 we have a more detailed trouble shooting. There are three basic assumptions that have to be fulfilled if the machine shall function properly: The oil pressure from tractor should be 180 bar.
