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.
