Daily Maintenance
Regular maintenance of your loader and hydraulic system will insure maximum loader efficiency and long life.
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.
Hydraulic Pressure Check
Following procedure outlines hydraulic pressure check.
1. Obtain a pressure gauge that measures 3000 PSI in 50 PSI increments.
2. Install gauge into the hydraulic line connecting the loader valve and to the base port of bucket cylinders.
3. Start engine and adjust to 1700-2200 RPM.
4. 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 pressure on the gauge.
5. If pressure is not correct, refer to “TROUBLESHOOTING” Section for possible remedy or contact your
dealer.
Escaping hydraulic fluid under pressure can penetrate skin, causing serious personal injury.
• DO NOT use your hand to check for leaks. Use
a piece of wood or cardboard and wear eye
protection to search for leaks.
• Stop engine and relieve pressure before
connecting or disconnecting lines.
• Tighten all connections before starting engine
or pressurizing lines.
NOTE: If any fluid is injected into skin, obtain medical attention immediately or gangrene may result.
