Releasing the residual pressure
After the auxiliary hydraulic circuits have
been used, pressure remains in the circuits.
This is called the residual pressure. Release
this residual pressure before disconnecting
the lines.
• If the machine has a bleeder unit, refer to
“Bleeder unit for simultaneous use with the
auxiliary 1st and 2nd (if equipped)” on page
2-69.
• If the machine has an accumulator, refer to
“Operating the machine with an
accumulator (if equipped)” on page 2-72.
• If the machine has neither of them, stand
