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.
2.
To check the tightness of the load regulation valves on
the boom cylinder drive the boom to a position in which
its movement can be reliably measured. Observe the
posible movement of the boom in a few minutes 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 80 -120
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.
Service instructions
1.
Disconnect and clean the valve.
2. Check the O-rings and replace, if necessary.
3. Put the valves carefully in place
4. Replace the valve, if necessary.
5. Do not change the settings of the valves
Support the platform, boom and outriggers in a position, in which the load does not rest on the
structure under repair. Make sure to relieve the residual pressure from the cylinders
