Check Points BeforeTrouble Shooting
In this chapter we have 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 if the machine shall function properly:
1. The oil pressure from the 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 connected using the test pressure points on the both main valve blocks. When no function is
operating the pressure will be the return line pressure. If the pressure is less than 150 bar, there will be less power for the functions. The build up the pressure manually close the master
valve or select and hold a function on e.g. CUT& START CLOSE.
Oil Flow
The minimum oil flow for the LA Model is 50 liters/minute, but it is recommended that it is 60 liters/minute and max. of 70.
30 liters / minute is the recommended oil flow for the 1814 ARC Model.
REMEMBER! Large oil amount = Valves get hot. (Small oil tank = 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.
