HAV Maintenance
Kubota

Diesel Engine
Checking Engine Oil
1. Check oil level before starting the engine or more than five minutes after it as stopped.
2. Remove oil dipstick, wipe it completely clean and replace it, remove it once more and
read the fluid level on the dipstick. If the oil level is too low, remove the oil filler plug and
add oil to the upper limit mark on the dipstick.
Oil Change
1. Remove the drain plug at the bottom of the engine and drain all the old oil. Draining the
oil will be easier and complete if done while engine is still hot.
2. Supply new engine oil up to the upper limit on the dipstick. NOTE: NEVER change the
oil while the engine is running.
3. If changing oil grades, be sure to remove ALL old oil before adding oil of the new grade.
Air Conditioning Service: (optional accessory)
1. Check the air conditioning condenser for excessive build-up of dirt, leaves, etc., in the
cooling fans. Blow out the condenser on a regular basis to ensure adequate air-flow
through the fins.
2. Check the air conditioning compressor drive belts and tighten as necessary. The
adjuster is located on the bottom side of the compressor. Tighten the belts until there is
enough play to twist the belts one quarter turn.
Greasing
1. Using a grease gun, add fresh grease to the tie rod ends, spindle pivots, and both rear
axle pivots.
