Engine Oil Filling

1.Add engine oil (Figure 26 or Figure 27). With filter change, the engine requires the following amounts:

Kawasaki gasoline engines: 1 qt. and 19 oz. (1.5 L) of oil per change.

Kubota diesel engines: 3 qt. (2.8 L) of oil per change.

2.Refer to oil viscosity guidelines for selection of oil grade (Figure 28 or Figure 29). See following CAUTION.

CAUTION

Do not exceed recommended oil capacity. Doing so will decrease engine performance or result in damage to the engine.

3.Install the oil filler cap.

4.Connect battery and spark plug (Gas only) wires. See Connecting the Battery – Gasoline/Diesel Vehicle on page 13.

5.With the Forward/Reverse handle in the NEUTRAL position, start and run the engine for three minutes and check for leaks. Observe both the drain plug and the oil filter from under the vehicle and watch for oil leaks. If the filter leaks, tighten an additional 1/4 turn and retest. If the oil drain plug leaks, re-torque and retest.

NOTE: Wait a few minutes after turning off the engine before removing the dipstick.

6.Remove the dipstick and check the engine oil as a final step. Replace the dipstick.

OIL VISCOSITY

Choose the viscosity according to the temperature as shown in the appropriate oil viscosity chart (Figure 28 or Figure 29). See following NOTE.
