Recommend of lubricating oil
Initial factory fill is high quality break-in oil for API Service CH-4 grade. During the break-in period,
frequently check the oil level. Somewhat higher oil consumption is normal until piston rings are
seated. The oil level should be maintained in the safe range between the Min. and Max. mark on the
dipstick. To obtain the best engine performance and engine life, Engine oil is specified by API
service, lettered designations and SAE viscosity numbers. If the specified engine oil is not available,
use a reputable brand of engine oil labeled for API Service CH-4 and SAE viscosity 15W40. Refer to
oil identification symbol on the container
4.6.3. Refilling with oil
z
Refill with fresh engine oil at the oil filler neck.
z
After refilling with oil, rotate the engine with the starter and move the shut-down lever to “stop” at the
same time until the oil pressure warning light goes out and the oil pressure gauge shows a pressure.
z
Then start the engine and allow it to run at medium speed for a few minutes. Check oil pressure and
tightness of system.
z
Then shut down the engine. After about 5 minutes, check the oil level. The oil level should now be at
the upper notch of the dipstick, but not higher.
z
Add any necessary oil to the upper dipstick mark.
