Check Points Prior to Troubleshooting
There are some general check points that have to be examined first if something is wrong with the machine. There are three basic assumptions that have to be fulfilled for the machine to
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.
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.
Oil Flow
The amount of oil that the tractor delivers should be minimum 25 liters/minute for satisfactory operation of the machine.
Note: (Max. allowed oil amount is 40 liters/minute). Ensure that oil level in tractor’s hydraulic system is correct and tractor’s oil filter is changed regularly. REMEMBER! Large oil amount will
mean that the Valves get hot. (Small Oil Tank will mean insufficient cooling).
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.
Electric Power
It is important to check that all functions receive enough electric power. If not, some, or all functions may fail.
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).
Procedure of Troubleshooting
If the machine fails to operate correctly it must be determined if the problem is Hydraulic, Mechanical or Electrical.
