Note regarding the modified release mechanism as of June 2004
When connecting the hoses, be aware of the following basic functions of the quick couplers:
Before coupling unlock the connect socket by turning the sleeve into position X. Retract sleeve
and connect plug and socket. Release sleeve and turn it into position Y.
Now the connection has been made and locked. Uncoupling is done in the reverse order.
Connection of the hoses is possible only, when they are depressurized.
In order to prevent contamination of the tool lines protect the couplings with delivered dust caps.
Attention
Quick-connect couplers partly have special functions. Therefore it is not allowed screwing off
them from the hoses or to exchange them!
To avoid pollution, the dust protection covers must be put on plug and socket if the couplings are
not connected. The dust protection covers must be connected to each other if the couplings are
connected.
6 Initial commissioning
Prior to commissioning the cylinders must be vented !
- Extend pistons without load approximately halfway.
- Turn cylinder upside down, the highest point of the cylinder must be lower than the the valve
block on the power unit.
- Extend pistons about twice by means of the corresponding valve so that air can escape from
cylinder and hoses.
7 Installation
7.1 Safety notes
7.1.1 Prior to installation of the cylinder, the load to be lifted must be properly secured against
rolling off in accordance with the applicable guidelines of the user’s country. Always observe the
load while moving it by means of a cylinder!
Do not stand below suspended loads. If in exceptional cases this cannot be avoided, these loads
must mechanically be sufficiently secured against movement in any direction!
7.1.2 General instruction for the installation / operation of all cylinders
-
Put the cylinder on a level, non-slip surface, (Attention: hydraulic oils may cause slippery films
on the ground!)
- The area of support must be a continous level surface (not a grating, gravel, etc.).
- Never put cylinders on a yielding support.
- Never use cylinders without piston guard plate in order to avoid damaging the piston and to
assure safe application of the force.
- Always use wooden supports between the piston guard plate and the jacking point.
- Always use LUKAS base plates (see accessories, chapter 9).
- Observe centred load initiation on the pistons ! If necessary try to find a better load
application point.
