Avoid High Pressure Fluids

X9811

· Hydraulic hoses can fail due to physical damage, kinks, age, and exposure. Check hoses and lines regularly. Replace damaged hoses and lines.

· Hydraulic fluid connections can loosen due to physical damage and vibration. Check connections regularly. Tighten loose connections.

· Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure.

· Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids.

· If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available from Deere & Company Medical Department in Moline, Illinois, U.S.A.
