Hydraulic System

The hydraulic system is under high pressure.
Before working on the hydraulic system:
•
depressurise the hydraulic system,
o
disconnect the hydraulic system from the external ener-
o
gy source.
Arrange for the hydraulic hose lines to be checked at least once
•
per year by an expert for their safe working condition.
Replace the hydraulic hose lines in the case of obvious defects,
•
damage and ageing. Only use original hydraulic hose lines.
Hydraulic hose lines must not be used for longer than six years
•
including any storage time of maximum two years.
Hoses and hose connections are also subject to natural ageing
with proper storage and permissible load, thus their storage time
and usage period are limited. However, the usage period can be
established in accordance with experience values, in particular
taking account of the hazard potential. The same guide values
apply for hoses and hydraulic hose lines made of thermoplastics.
Never try to seal leaking hydraulic hose lines with your hand or
•
fingers.
Highly pressurised liquid (hydraulic oil) can penetrate through
the skin into the body and cause severe injuries.
Contact a doctor immediately in the case of injuries caused by
hydraulic oil. Danger of infection.
Never track down leaks with your bare hands due to the possible
•
severe risk of infection. Use suitable aids for the search for leaks
(cleaning spray, special leak detection spray).
