Hydraulic Hose Inspection

Hydraulic hoses are subject to extreme conditions such as, pressure differentials during operation and exposure to weather, sun, chemicals, very warm storage conditions or mishandling during operation or maintenance. These conditions can cause damage or premature deterioration. Hoses that move during operation more susceptible to these conditions than others.

Hydraulic Hose Inspection

Inspect the hoses frequently for signs of deterioration or damage. Make sure hoses are properly routed and protected from abrasion. Note: Toro recommends replacement of moving hydraulic hoses, such as those connected to cutting unit drive motors and implement lift cylinders, every 2000 hours or 2 years, whichever comes first. When replacing a hydraulic hose, be sure that the hose is straight (not twisted) before tightening the fittings. This can be done by observing the imprint on the hose. Use two wrenches; one to hold the hose straight and one to tighten the hose swivel nut onto the fitting. Use procedures shown in the Toro Hydraulic Hose Servicing Manual, Part No. 94813SL.

WARNING

Before disconnecting or performing any work on hydraulic system, all pressure in system must be relieved by stopping the engine and lowering or supporting the implement.

Keep body and hands away from pin hole leaks or nozzles that eject hydraulic fluid under high pressure. Use paper or cardboard, not hands, to search for leaks. Hydraulic fluid escaping under pressure can have sufficient force to penetrate the skin and do serious damage. If fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this type of injury or gangrene may result.
