Procedure of Troubleshooting
If the machine fails to operate correctly it must be determined if the problem is Hydraulic, Mechanical or
Electrical.
Solenoid Valves
When checking if the Solenoid valves are receiving electric power, you do this in the following way:
1. Unscrew the nut that holds the solenoid.
2. The solenoid is easy to move without electric power.
3. Push the current function on the remote control. If the solenoid gets power, it will be difficult to move,
it “sticks”. This is the best and easiest way to check if the solenoid valve is receiving electric power. Another
way is to hold a screwdriver up to the magnet. If it “sticks”, the solenoid is receiving electric power.
The power supply to the valve can also be measured with a voltmeter, but then the contact must be
connected to the solenoid, so it is using power. To have reliable functions, the voltage should not be lower
than 11,5 volts, even if the solenoid valve usually works with a little lower voltage.
If the electric supply is in order and one of the functions fails, the reason can be dirt that tightens or
prevents the sliding shaft (spool) from moving.
Try to manoeuvre the function manually, by pressing the point of a screwdriver into the end of the valve
housing. At the same time the corresponding switch on the control unit has to be operated to get electric
power to the master valve. If the function is working again after this, the dirt may have been pushed out in
the oil system and the machine can be operated normally again.
Take care so that the machines moving parts, do not cause damage to persons or objects.
