MAINTENANCE

Checking the Hydraulic Lines

After every 100 operating hours, check the hydraulic
lines and hoses for leaks, loose fittings, kinked lines,
loose mounting supports, wear, and weather or chemical
deterioration. Replace all moving hydraulic hoses every
1500 hours or 2 years, whichever comes first. Make
necessary repairs before operating.
