Check fluid level of tractor hydraulic system before starting each day’s operation. If necessary, add hydraulic oil as recommended in your tractor operator’s manual.892. After every eight hours of operation, lubricate all twelve grease fittings; one at each end of lift boom arms and one at rod and base ends of each lift and bucket cylinder.893. After every ten hours of operation, check all hardware and tighten where required.894. Replace hoses immediately if they are damaged by a cut or scrape, extruded at the fittings or leaking. Hydraulic oil leaks should be repaired promptly to avoid loss of oil and serious personal injury from escaping oil.89Hydraulic Pressure Check901. Obtain a pressure gauge that measures 3000 PSI in 50 PSI increments.902. Install gauge into the hydraulic line connecting the loader valve and to the base port bucket cylinders.903. Start engine and adjust to 1700-2200 RPM.904. Push bucket control lever to pressurize the hydraulic line with the gauge attached. Hold the control until the cylinders reach the fully extended position. Holding the control with cylinders fully extended will give you the hydraulic system pressu...905. If pressure is not correct, refer to “TROUBLESHOOTING GUIDE” in the Operation Section for possible remedy, or contact your dealer.90Cylinder Service90Lift and Bucket Cylinder Dissemble911.
