Installation
•
When connecting the hydraulic system, make sure that the connecting hoses have no friction points
and that they do not hook into protruding edges during the lifting and lowering movement and could
therefore break off.
•
The supply values must be maintained to ensure that the unit functions correctly and reliably.
•
On all units supplied without a rotator, a hydraulic hose with dummy plugs is connected to port "B"
(return flow) of the valve block.
•
By means of this hose the pressurised hydraulic oil, which is still in the cylinder, can be drained into a
container.
•
Remove the blind plug only above the tank! The hose can then be unscrewed so that the hydraulic
connections can be realised.
It is pointed out again that to avoid faults and malfunctions, the correct connection of the hydraulic hoses
must be checked before each start-up of the machine!
