7.1.3 Note on retracting the cylinder
The load may only be lowered with the pump running. Otherwise a vacuum could be created which
would cause air to enter the hydraulic system.
8 Hydraulic connection and operation
8.1 General
Prior to connecting the hoses carry out correct cylinder installation as per chapter 7. Make sure that
the pump is switched off!
8.1.1 Connecting the telescopic cylinders
As described in chapter 5.3, first connect the blue hose, then the red hose of the pair of hoses.
8.2 Operation of cylinders
Operate the cylinders as per operating manual of the power unit delivered with the cylinders.
9 Accessories
9.1 Base plates
Base plates are designed to:
- enlarge the floor space of the cylinder,
- increase static stability,
- level out unevenness of the ground.
9.1.1 Mounting the base plates
Put cylinder on the base plate in such a way that the coupling connector meshes with groove of the
guide collar. Tighten the three srews on the guide collar. Now the cylinders can be carried together
with the base plate.
9.2 Stacking sets
9.2.1 Attributes of stacking sets
Multistage sets prolong the stroke of a cylinder. For space reasons, cylinders with large strokes
often cannot be used due to their large overall height. Multistage sets make it possible to use
cylinders with small overall height to lift loads very high.
Generally multistage sets consist of:
-
cylinder attachments
- piston attachments
- piston protection plate
- forked lever.
