WARNING!
If a hydraulic leak develops, correct it immediately. Escaping
hydraulic oil can have extremely high pressure. A stream of
high pressure oil may easily penetrate the skin as with modern
needle-less vaccination equipment - but with the exception
that hydraulic fluid may cause blood poisoning. It is impera-
tive that the connections are tight and that all lines and pipes
are in good condition. .
