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