Kubota U35-4 Excavator F.A.Q.

What is the recommended maintenance schedule for the Kubota U35-4 Excavator?

The recommended maintenance schedule includes daily checks of engine oil, coolant, air filter, and hydraulic fluid levels, as well as greasing all pivot points. Additionally, perform a more thorough inspection every 250 hours, including changing engine oil and filter, hydraulic oil filter, and checking the track tension.

How do I properly adjust the track tension on a Kubota U35-4?

To adjust track tension, lift the machine off the ground using the boom and blade. Loosen the grease valve slightly to release tension, then use a grease gun to add grease and adjust tension. The correct sag should be about 20-30 mm (0.8-1.2 inches) when measured from the track frame.

What are the common troubleshooting steps if the excavator won't start?

Check the battery connections and charge, inspect the fuel level and quality, ensure the safety lock lever is in the neutral position, and check the starter motor and ignition switch for faults. If problems persist, consult the operator's manual or a professional technician.

How can I improve the fuel efficiency of my Kubota U35-4?

To improve fuel efficiency, ensure regular maintenance, use the correct engine oil, avoid excessive idling, and operate the machine at optimal engine speed. Properly maintaining the hydraulic system and keeping the air filters clean also helps enhance fuel efficiency.

What should I do if the hydraulic system is operating sluggishly?

Check the hydraulic fluid level and top it off if necessary. Inspect hydraulic hoses and connections for leaks or blockages, and ensure the hydraulic filter is clean. If the issue persists, consider consulting a qualified technician to inspect the hydraulic pump and valves.

How do I perform a quick inspection before using the Kubota U35-4?

Conduct a walk-around inspection checking for visible leaks, damage, and loose parts. Check fluid levels, including engine oil, coolant, and hydraulic fluid. Inspect the tracks for wear and proper tension, and verify the functionality of lights and indicators.

What precautions should be taken when operating the Kubota U35-4 in cold weather?

In cold weather, ensure the engine and hydraulic fluids are appropriate for low temperatures. Allow the engine to warm up before operating, check battery charge, and use block heaters if available. Also, inspect the undercarriage for ice build-up and remove any debris.

How can I safely transport the Kubota U35-4 Excavator?

Secure the excavator on a trailer using chains and binders, ensuring that the machine is centered and balanced. Lower the boom and blade to the trailer deck, lock the safety lever, and check that all tie-down points are secure before transporting.

What is the procedure for changing the engine oil on a Kubota U35-4?

To change the engine oil, run the engine until warm, then turn it off. Remove the oil drain plug and allow the oil to drain completely. Replace the oil filter, reinstall the drain plug, and refill with the recommended oil type and amount. Ensure correct oil level with the dipstick.

How do I calibrate the control levers for optimal operation?

Calibrating control levers typically requires professional service, but ensure regular maintenance and inspection of linkage and hydraulic connections. Follow the manufacturer's manual for any minor adjustments or contact a certified technician for complex calibration.
