ENGINE OIL AND FILTER CHANGE

The engine oil and oil filter should be changed at the following intervals:

•Kawasaki gasoline engine: after the first 10 hours of operation.

•Kubota diesel engine: after the first 50 hours of operation.

After that, the oil should be changed every 100 hours of operation or annually, whichever comes first.

Engine Oil Draining

1.Turn the key switch to the OFF position and remove the key. Place the Forward/Reverse handle in the NEUTRAL position. Chock the front wheels.

2.Disconnect battery and spark plug (Gas only) wires. See Disconnecting the Battery – Gasoline/Diesel Vehicle on page 13.

3.Remove the oil filler cap to allow the oil to drain properly.

4.Position a pan designed for oil changes under the drain plug (Figure 21 or Figure 22).

5.From the underside of the vehicle, use a socket or wrench to remove the drain plug (1). Turn the plug counterclockwise and drain the engine oil into the pan. See following WARNING.

WARNING

•Do not attempt to change engine oil when the engine is hot or even warm. Hot engine oil can cause skin burns.

•Wear safety glasses or approved eye protection when servicing the vehicle. Wear rubber gloves when handling oil drain plug, oil filter, and oil drain pan.

6.Clean the oil drain plug threads with solvent to remove oil and oil residue. Make sure that the compression washer or sealing o-ring remains on the drain plug. Inspect the compression washer or the sealing o-ring and replace if necessary.
