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
To check the oil pressure into the machine is high enough, a gauge may be placed in line on the feed hose
or there is a standard test point on the end of the Control Valve.
Oil Flow
The amount of oil that the tractor delivers should be minimum 20 liters/minute for satisfactory operation
of the machine, but it is recommended that it is 30 liters/minute.
Note: (Max. allowed oil amount is 60 liters/minute). Ensure that oil level in tractor’s hydraulic system is
correct and tractor’s oil filter is changed regularly.
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 pressure is 10 bar, we recommend “free return” directly to the tank.
