Checking Hydraulic Lines
After every 25 operating hours, check the hydraulic lines
and hoses for leaks, loose fittings, kinked lines, loose
mounting supports, wear, weather, and chemical
deterioration. Replace all moving hydraulic hoses every
1500 hours or 2 years, which ever comes first. Make
necessary repairs before operating.
Warning
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury. Fluid injected
into the skin must be surgically removed within a
few hours by a doctor familiar with this form of
injury or gangrene may result.
Keep your body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fluid.
Use cardboard or paper to find hydraulic leaks,
