Instruction ManualPage 106 Installation manual6.1 Personal protection6.2 How to remove protection materialBefore unpacking the cylinder check the warning labels that areattached to the cylinder and read the instruction that are written onthe labels.Before and during unpacking the cylinder check if there are anydamaged 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 forcylinders are described in the following lines:In case a bracket is used, to prevent the piston rod from extending duringtransportation, this must be removed carefully. When removing the bracketnobody may be standing in front of the piston rod, because the piston rod couldextend. When the cylinder needs to be mounted upside-down with the pistonrod directing downwards, then the bracket that holds the piston rod in positionmust remain in place, until the cylinder is mounted. Be aware, when removingthe bracket that holds the piston rod in position the piston rod could extendbecause of its own weight. For double acting cylinders, extending of the pistonrod can be prevented by building up pressure on piston rod side.6.3 Step by step installation guide1. Cylinders can be filled with nitrogen or partly filled with oil and VSI dope.Be careful, there can be some over pressure in thecylinder. Release pressure first and do not breath theescaping gas.2. Make sure all parts are cleaned and free of dust or any otherthreatening materials or media (such as water). Also clean the blankparts that are greased or equipped with preservation oil. The hoses andhydraulic pipes should be flushed (oil cleanliness according chapter8.3), before connecting these hoses or pipes to the cylinder. Ensureevery hose, pipe and/or valve is connected.3. Cylinders which go “over-centre”, when they extend, should first be filledwith oil and air-released, as per chapter 6.5.4. Before mounting the cylinder make sure all the bearings and pins aregreased.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 loadmust be a 100% axial load on the cylinder. Side loads or radial loadscan be disastrous for cylinders, unless the cylinders are designed to
