Figure 25 Add Engine Oil – Gasoline Vehicles
Engine Oil Filling
1. Add engine oil; use a funnel or pour spout to direct the oil into the opening (Figure 25 or Figure 26). With
filter change, the engine requires:
– 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 27 or Figure 28). See following CAUTION.
CAUTION
• Do not exceed recommended oil capacity. Doing so will decrease engine performance or result in
damage to the engine.
3. Connect the battery cables, positive (+) cable first, and tighten terminals to 144 in-lb (16 N·m). Coat terminals with
Battery Terminal Protector Spray (P/N 603 00 00-03).
4. With the Forward/Reverse handle in the NEUTRAL position, start and run the engine for a few minutes. Observe
both the drain plug and the oil filter from under the vehicle and watch for oil leaks. If a leak is detected, check
the tightness of the oil filter and drain plug. Tighten, repair, and/or replace components as necessary. See
following NOTE.
NOTE: Wait five minutes after turning off the engine before removing the dipstick.
5. Remove the dipstick and check the engine oil as a final step. Replace the dipstick.
