Technical Information 1. GENERAL NOTES The potential hazards to man and the environment posed by hydraulic systems is very often underestimated in practice. The wrong choice or improper use of components, hoses, fittings and accessories can compromise the product's functional reliability, causing it to fail and possibly posing a threat of personal injury or material damage. In extreme cases, violently spraying oil, shearing fittings and ruptured lines can even cause fatal injuries. Exceeding of the maximum permissible working pressure must be avoided. We therefore expressly recommend that...

Technical Information 2. COMMISSIONING OF HYDRAULIC SYSTEMS The proper functioning of hydraulic systems presupposes compliance with the respective commissioning and maintenance instructions. All work on hydraulic systems and the components contained must be carried out in strict observance of the safety regulations. There must be no pressure inside the oil-dynamic circuit, i.e. loads must be lowered, pumps switched off and pressure accumulators relieved. The maximum loads (pressures, forces, temperatures) given in the product documentation must not be exceeded. Furthermore, the hydraulic...
