1. Is the connection between battery cable and counter box OK Clean off the poles and check that the plug comes correct in place Is the connection between counter box and machine OK Change contacts if any doubt about the condition Is the fuse on the battery cable OK PLEASE CONTACT YOUR DEALER IF YOU ARE IN DOUBT OF ANYTHING Remember always to give your dealer the serialnumber and productionyear of your machine when contacting dealer and when ordering spare parts Emergency stop see chapter 1 0 26 Fig 16 1 BEWARE OF MOVING PARTS WHEN TESTING THE MACHINE 16 0 16 1 16 2 PROCEDURE OF TROUBLE SHOOTING EMERGENCY STOP The emergency stop is constructed so that the electric circuit must be closed to be able to start the machine As soon as it s broken the machine will stop This is shown on the counter units display by two points lighting up See chapter 5 0 When the emergency stop is activated there shall be measured 4 volts over the emergency stop switch EMERGENCY STOP VALVE When you shall check if the emergency stop valve gets electric power you do this in the following way 1 Unscrew the nut that holds the solenoid 2 The solenoid is easy to move without electric power 3 When the emergency stop arm is in correct position and the reset button on the counter box is pressed there shall be electric power to the solenoid If the solenoid gets power it will be difficult to move it sticks2. gauge to the oil pressure hose for example on the quick coupler If the pressure is less than 180 bar there will be less power for the functions The first place you trace this is at the ROLLERS OUT IN OIL AMOUNT The oil amount that the tractor delivers must be minimum 15 liters minute but it is recommended that it is 25 liters minute Max allowed oil amount is 40 liters minute REMEMBER Large oil amount Valves get hot Small oiltank insufficient cooling COUNTER PRESSURE The counter pressure can be too high With high counter pressure the machines function s will get less power High counter pressure means also that you need more power to operate the valves MAX ALLOWED COUNTER PRESSURE IS 10 BAR If you are in doubt about the counter pressure arrange a free return directly to the tank If the counter pressure goes over 105 bar the emergency stop valve S2 will open and let the oil out on the ground through the outlet tube See chapter 14 4 ELECTRIC POWER It is important to check that the emergency stop function gets enough electric power Do the two points in the display light up See chapter 5 4 and 5 5 If not the machine cannot be started Is the battery voltage high enough If the voltage falls below 9 volts the emergency stop valve will not be able to open for the oil flow to the wrapping arm Are the cables correctly connected to the battery Follow directions in chapter 4 4 and 13 0
3. 10 44 45 Fig 4 3 ELECTRIC CONNECTION The electric equipment on Auto Wrap 1200 M consists of an emergency stop switch on the wrapping arm an electric operated emergency stop valve and a switch that count the number of revolutions of the wrapping arm It is all controlled by an electronic counter unit that also is used to reset the emergency stop See fig 4 2 The counter has to be connected to the tractor s 12 volts battery BROWN leader to the plus pole and BLUE leader to the minus pole To secure against short circuits there is an 8A fuse on the plus leader near to the battery pole The 7 pin plug shall be connected to the contact on top of the machine See also chapter 5 0 Emergency stop MECHANICAL LEVER CONTROL The control unit consists of a control block with three levers connected to the machine with wire transmission The control block should be attached to a suitable place in the tractor cab When the balewrapper is not in use the lever block should be placed on the machine See fig 4 3 The fastening bracket for mounting in the tractor cab is also placed here by delivery Emergency stop see chapter 1 0 11 Normal position 4 6 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

O 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 AUTO WRAP 1200 M is hydraulically driven by the tractors hydraulic system and is mechanically controlled from the tractor cab with levers The machine can either be mounted to three point linkage front mounted with quickcouplers to the tractors frontloader or on a wheel loader Then it s possible to stack the bales upon each other AUTO WRAP 1200 M is designed to wrap bales of grass hey or straw with nominal diameter of 3 5 ft 110 170cm and weights up to 1760 Ibs 800kg 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 AUTO WRAP 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 See also chapter 19 0 conditions of warranty EMERGENCY STOP Auto wrap 1200 M is equipped with a so called eme

This is the best and easiest way to check if the emergency stop valve gets electric power Another way is to hold a screwdriver up to the magnet If it sticks the solenoid gets electric power The power supply to the valve can also be measured with a voltmeter but then the contact must be connected to the solenoid so it is using power To have reliable functions the voltage should not be lower than 11 5 volts even if the magnet valve usually works with a little lower voltage Emergency stop see chapter 1 0 27 17 0 TROUBLE SHOOTING 171 MACHINE DOES NOT FUNCTION a Even if the gauge shows enough pressure there is no reaction in the machine The reason could be that one or both of the quick couplers does not open for the oil Change quick couplers b The counter pressure could be too high Max allowed counter pressure is 10 bar See chapter 15 2 Make sure that the crane handle is turned into correct position See chapter 4 7 Disturbances of this type a b or c are most likely in the first days that the machine is in use 17 2 CUTTER WRAPPING ARM OR ROLLERS WIDTH DOES NOT FUNCTION The reason might be that the wires has loosen their tension and has to be tensioned See chapter 12 7 17 3 THE CUTTER WILL NOT HOLD THE FILM The pressure is falling and the springs start to lift the cutter See chapter 14 2 174 THE WRAPPING ARM WILL NOT ROTATE a The bolt that secure the wrapping arm du
