WARNING
Do not attempt to disconnect hydraulic lines and fittings while engine is running or before
hydraulic system pressure has been released. When engine is running, hydraulic system
is under pressure. Hydraulic system pressure should be 0 psi (0 kPa) before lines are
disconnected. A line or fitting disconnected under pressure will blow off with a lot of force
and could cause serious injury to personnel.
Be careful when draining hot fluids. Wear gloves to protect your hands from hot parts and
fluids or severe burns could result.
