High Pressure Fluid Hazard:
Releive pressure from all lines before
working on hydraulic connections. Wear
eye protection and gloves when opening hydraulic
connections. Open connections slowly. Use a piece of
paper or cardboard, NOT BODY PARTS, to check for leaks. Escaping
fluid under pressure can have sufficient pressure to penetrate the skin
causing serious injury. If an accident occurs, seek immediate medical
assistance from a physician familiar with this type of injury.
