hydraulic tank dipstick is slowly loosened to relieve pressure. Failure to comply may result
in severe injury or death to personnel.

could result if pump is not handled with caution.
Before performing any hydraulic troubleshooting in the bowl, move the ejector forward
and disable it by disconnecting the ejector cylinder or by engaging the ejector lock. Failure
to comply may result in severe injury or death to personnel.
Spilled hydraulic oil is very slippery. Be careful when entering or working in bowl area.
Wipe up any spilled oil immediately. Failure to comply may result in severe injury to
