12. If a hydraulic leak develops, correct it immedi-
ately. Escaping hydraulic oil can have ex-
tremely high pressure. A stream of high
pressure oil may easily penetrate the skin as
with modern needle-less vaccination equip-
ment - 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. If an in-
jury is caused by the escaping hydraulic fluid,
see doctor at once!
13. Use a piece of cardboard or wood to detect
leaks of hydraulic oil under pressure.
14. Be sure to relieve all hydraulic pressure before
disconnecting any lines or pipes between the
implement and the tractor hydraulic system.
Keep all guards and shields in place.
