Abschnitt 2.3 - 2.3 Searching for leakages

Searching leakages on machines has to be conducted systematically at reduced system pressure, if possible, and with personal protection equipment, e. g. gloves, protective rubber clothes, goggles, or helmet with visor, and by using aids such as blotting papers.

It has to be taken into account that the hydraulic fluid leaking from the leakage points (cracks, fissure) under high pressure causes very serious injuries or intoxications when coming into contact with the human body! Even the use of protective clothes, including protective gloves, does not provide for complete protection.

In any case, keep away from possible leakage points.
