12. 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 imperative that the connections are tight and that all
lines and pipes are in good condition. If an injury is caused by the escaping hydraulicfluid,
see doctor at once!
13. Use a piece of cardboard or wood to detect
leaks of hydraulic oil under pressure.
14. Besureto relieveallhydraulic pressure before
disconnecting any lines or pipes between the
implement and the tractor hydraulic system.
Keepall guards and shields in place.
