Do not attempt to disconnect hydraulic lines and fittings while engine is running or before

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
