High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines. Use
paper or cardboard, NOT BODY PARTS, to check for leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems. Escaping fluid under pressu
can have sufficient pressure to penetrate the skin causing se
ous injury. If an accident occurs, seek immediate medical
assistance from a physician familiar with this type of injury.
Only trained personnel should work on system hydraulics.
