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 has to be as free as possible,
max. 10 bar counter pressure
.
3.
Enough electric power to all functions.
14.1 OIL
PRESSURE.
In order to check that the oil pressure into the machine is high enough, a guage 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 oiltank = insufficient cooling).
14.2 RETURN
PRESSURE.
The return pressure can be too high. With high return pressure the machine's functions will get
less power. High return pressure means also that you need more power to operate the valves.
MAX. ALLOWED RETURN PRESSURE IS 10 BAR.
We recommend "free return" directly to the tank.
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 remote control unit 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 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).
