10.1. 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. The return coupling must be connected to a free return point on the tractor.
3. Good electric power to all functions. If the voltage drops below 12V the performance of the machine will be affected.
10.1.1. 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.
The pressure of the oil circulating through the machine when it is sitting idle should be especially 30 Bar. When a cylinder, for example the Cut & Start is powered to the end of stroke the
oil pressure should rise to the relief valve pressure of 180 bar.
10.1.2. Oil Flow
The amount of oil that the tractor delivers should be minimum 30 liters/minute for satisfactory operation of the machine, but it is recommended that it is 40 liters/minute.
Note: (Max. allowed oil amount is 80 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.
10.1.3. 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 and the parking brake on the wrapping arms will be less effective. MAX. ALLOWED RETURN PRESSURE IS 10 BAR. A “free return” directly to the tank should be used.
