6.1 Personal protection
6.2 How to remove protection material
Before unpacking the cylinder check the warning labels that are
attached to the cylinder and read the instruction that are written on
the labels.
Before and during unpacking the cylinder check if there are any
damaged parts of the cylinder occurred during transportation.
First remove all package material, like plastic stretch seals and Denso
®
tape,
before installing the cylinder. Some of the common used package materials for
cylinders are described in the following lines:
In case a bracket is used, to prevent the piston rod from extending during
transportation, this must be removed carefully. When removing the bracket
nobody may be standing in front of the piston rod, because the piston rod could
extend. When the cylinder needs to be mounted upside-down with the piston
rod directing downwards, then the bracket that holds the piston rod in position
must remain in place, until the cylinder is mounted. Be aware, when removing
the bracket that holds the piston rod in position the piston rod could extend
because of its own weight. For double acting cylinders, extending of the piston
rod can be prevented by building up pressure on piston rod side.
6.3 Step by step installation guide
1. Cylinders can be filled with nitrogen or partly filled with oil and VSI dope.
Be careful, there can be some over pressure in the
cylinder. Release pressure first and do not breath the
escaping gas.
2. Make sure all parts are cleaned and free of dust or any other
threatening materials or media (such as water). Also clean the blank
parts that are greased or equipped with preservation oil. The hoses and
hydraulic pipes should be flushed (oil cleanliness according chapter
8.3), before connecting these hoses or pipes to the cylinder. Ensure
every hose, pipe and/or valve is connected.
3. Cylinders which go “over-centre”, when they extend, should first be filled
with oil and air-released, as per chapter 6.5.
4. Before mounting the cylinder make sure all the bearings and pins are
greased.
5. Read chapter 4 ‘Lifting instructions’ first before lifting the cylinder.
6. Ensure the centreline of the cylinder is in line with the load. The load
must be a 100% axial load on the cylinder. Side loads or radial loads
can be disastrous for cylinders, unless the cylinders are designed to
