REPAIR INSTRUCTIONS
Hydraulic pressure for weight
transfer
The hydraulic pressure is not adjustable, it is
controlled by the feed pressure from the drive
system’s hydraulic pump.
If this is incorrect, clean or replace the
pressure limiting valve, which is located
underneath the hydraulic pump. See the
Sauer-Danfoss manual.
Replacing the solenoid valve
In the event of an electrical fault, the electrical
section of the solenoid valve can be replaced
without the hydraulic section being
dismantled. Make sure that the electrical
section is intended for 12 V.
To trouble shoot solenoid valves, measure
the coil resistance using an ohmmeter to
establish whether the electrical section is
faulty.
Guideline value coil resistance:
• 30 W. coil 4.8
• 26 W. coil 5.7
• 20 W. coil 7.5

IMPORTANT INFORMATION
The double solenoid valve for the accessory
hydraulic kit has four sealing rings. There is a
risk when assembling the valve that one of the
rings can become unseated and be damaged.
Exercise caution and secure the rings using
grease before assembly.
