inspect all hoses for cuts or wear. Check for signs
of leaks and make sure all fittings are tight.
WARNING
To avoid personal injury or death:
• Escaping the hydraulic fluid under pressure
can obtain sufficient force to penetrate skin,
causing serious personal injury.
Before disconnecting lines, be sure to
relieve all pressure. Before applying
pressure to the loader system, be sure that
all connections are tight and that lines,
tubes, and hoses are not damaged. Fluid
escaping from a very small hole can be
almost invisible. Use a piece of cardboard or
wood, rather than your hands, to search for
suspected leaks.
If you are injured by escaping fluid, see a
doctor at once. Serious infection or allergic
reaction will develop if proper medical
treatment is not administered immediately.
