HYDRAULIC OIL LEAKAGE
WARNING High-pressure hydraulic oil spray is dangerous. Spray can puncture
and become embedded beneath the skin or contaminate the eyes. Ensuer
pressure is relieved by actuating the controls while the hydraulic power source is
off
and emergency lowering valves have been opened, before loosening
connections.
Loose fittings should be re-tightened.
CAUTION , do not overtighten and “stretch” threads or cause distortion to components.
Leaks occurring at flexible hose fittings cannot be rectified, the complete hose must be
renewed.
The cylinder valve blocks are retained by banjo bolts, these must not be tightened to
more than 25Nm.
