LOAD HOLDING AND LOAD REGULATION VALVES
Check of operation
1.
To check the tightness of the outrigger cylinder load holding valves measure the height position of the
chassis from the floor separately at each outrigger. After a few minutes, measure the height again.
2.
To check the tightness of the load regulation valves on the boom cylinder and the cylinders of the
articulated arms drive the boom to a position in which its movement can be reliably measured.
Observe the possible movement of the boom in a few minute´s time.
3.
To check the tightness of the load regulation valve on the telescope cylinder extend the telescope and
stop the movement at any position, measure the stroke and observe in a few minutes time that the
stroke does not change. (Note! Drive the boom to an almost vertical position).
4.
To check the tightness of the load regulation valve on the platform levelling system, put a load of 100
- 200 kg on the platform and measure the distance from the rear edge of the platform to the floor.
Observe for a few minutes that its height position does not change.

4.
Replace the valve, if necessary
