14.0 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:
1. The oil pressure from tractor should be 180 bar.
2. The return flow of oil (See 14.2 below)
3. Enough electric power to all functions.
4. Remember that the RESET button on the control unit must be pressed when the control
unit is switched on to allow the wrap arm to move (the control unit monitor should show
an arrow an the left side)
14.1 OIL PRESSURE.
In order to check that the oil pressure into the machine is high enough, a gauge may be applied
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 oil tank = insufficient cooling).
14.2 RETURN
PRESSURE.
The 1300S machine must have a “free return” directly to tank on the arm rotation service.
The return pressure on the second service should be less than 10 Bar .
14.3 ELECTRIC POWER.
It is important to check that all functions receive enough electric power.
If not, some, or all functions may fail .
Is the battery voltage high enough?
If the voltage falls below 9 volts the valves will not be able to open.
Are the cables correctly connected to the battery?
Follow directions in chapter 4.4
Is the connection between battery cable and control unit OK?
Clean off the poles and check the plug .
Is the connection between the control unit and machine OK?
Change contacts if any doubt about the condition.
Is the fuse in the ‘Cobo ‘ plug ( or on the battery cable if that is being used) OK?
Is the switch on the back of the control unit switched on?
PLEASE CONTACT YOUR DEALER IF YOU ARE IN DOUBT ABOUT ANYTHING.
(Remember always to give your dealer the serial number and production year of your
machine when contacting dealer and when ordering spare parts).
