WARNING
Escaping fluid!
Hydraulic fluid or diesel fuel leaking under
pressure can penetrate the skin and cause
infection or other injury. To prevent personal
injury:
Relieve all pressure before discon-
necting fluid lines or performing work on the
hydraulic system. Before applying pressure,
make sure all connections are tight and all
components are in good condition. Never use
your hand to check for suspected leaks under
pressure. Use a piece of cardboard or wood
for this purpose. If injured by leaking fluid, see
your doctor immediately.
Failure to comply could result in death or seri-
ous injury.
