        • MAINTENANCE SECTION
  • Lubrication Schedule
  • Daily Maintenance
    • 1. 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.
    • 2. After every ten 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.
    • 3. After every ten hours of operation, check all hardware and tighten where required.
    • 4. 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.
