Checking Hydraulic Lines
After every 25operating 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.
POTENTIAL HAZARD
Hydraulic fluid escaping under pressure
can penetrate skin and cause injury.
WHAT CAN HAPPEN
Fluid accidentally 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.
HOW TO AVOID THE HAZARD
Keep body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fluid.
Use cardboard or paper to find hydraulic
leaks, never use your hands.
