14. 15 cm above the ground Close the rollers completely The rollers must not under any circumstances hit the ground while closing The reason why the rollers shall not hit the ground is that this will increase the wearing on the gears and the bearings of the rollers HEIGHT ADJUSTMENT OF TOWER PRESTRETCHER The tower is adjustable up or down after the bale size It has three fixed adjustments The tower and the wrapping arm with prestretcher are rather heavy so it is recommended to use a tackle or the front loader to lift it Tighten the properly after adjustment 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 See chapter 6 6 START Remember that the plastic film end has to be locked in the U shaped slot before starting the wrapping When the plastic film end is in the slot push START 8 and the wrapping arm now moves at 1 2 speed for approx one half revolution before it automatically switches to full speed This is to avoid damage of the film when starting When the wrapping arm has done a couple of revolutions the cutter arm automatically releases the film end See also chapter 10 7 OVERLAP Control that the overlap is correct If not see chapter 9 0 HOW MANY LAYERS OF PLASTIC FILM When the bale is completely covered with film read the co

16. 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 Emergency stop see chapter 2 1 6 2 6 2 7 2 8 2 9 LOCKING THE WRAPPING ARM When the machine is not in use make sure the locking bolt for the wrapping arm is mounted and that the secure pin is fitted If the bolt is not mounted the wrapping arm and or the machine could be damaged during transport See fig 2 6 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 FRONT MOUNTING 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 TRANSPORTING When transported on a public road there are certain safety measures that must be taken 1 Make sure that the locking bolt on the wrapping arm is mounted C

ESTRETCHER PLASTIC FILM The plastic film shall hit at the middle of the bale wrapped and therefore it can be necessary to adjust 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 adjust the 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 Emergency stop see chapter 2 1 15 7 0 CONTROL BOX Type CR 900 6 Ty TELLEFSDAL A S IMPORTANT Read this section on the function and operation of the control box thoroughly BEFORE using the machine AUTO WRAP IN GENERAL DELTA CR 900 6 for Auto Wrap bale wrappers is a new control box specially designed for the new 2 machines produced for the 1996 season These Yemen ned machines have a number of working operations eA PERO and consequently several different operations are programmed in the control box This control box also replaces previous models and is therefore interchangeable with regard to connections etc The control box automatically detects which wiring circuit it is connected to and consequently which machine it will be controlling KNIV KLEMMARM RULLER WALZEN NOTE ROLLS In order for the software in the control box to identify the machine to which it is connected and run the correct program the service technicians and end user must follow the in
