REMOVAL
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.
