Running the engine with a low oil level can cause engine 
damage. 

The Oil Alert system (applicable engine types) will 
automatically stop the engine before the oil level falls below 
the safe limit. 

However, to avoid the inconvenience of an unexpected 
shutdown, fill to the upper limit, and check the oil level 
regularly.

Screw in the filler cap/dipstick securely.

Oil is a major factor affecting performance and service life. Use 
4-stroke automotive engine oil.

SAE 10W-30 is recommended for general use. Other viscosities 
shown in the chart may be used when the average temperature in 
your area is within the recommended range.

The SAE oil viscosity and service classification are in the API label 

on the oil container. We recommend that you use API SERVICE 
Category SE or SF oil.

and dry them thoroughly. 

Place the O-ring in the fuel valve, and install the sediment 
cup. Tighten the sediment cup securely. 

Move the fuel valve to the ON position, and check for leaks. 
Replace the O-ring if there is any leakage.
