Avoid High-Pressure FluidsInspect hydraulic hoses periodically – at least onceper year – for leakage, kinking, cuts, cracks, abrasion,blisters, corrosion, exposed wire braid or any other signsof wear or damage.

Replace worn or damaged hose assemblies immediatelywith John Deere approved replacement parts.

Escaping fluid under pressure can penetrate the skincausing serious injury.

Avoid the hazard by relieving pressure beforedisconnecting hydraulic or other lines. Tighten allconnections before applying pressure.

Search for leaks with a piece of cardboard. Protect handsand body from high-pressure fluids.

If an accident occurs, see a doctor immediately. Any fluidinjected into the skin must be surgically removed within
