ASSEMBLY
4. Check engine oil level before every use and add as needed.
MAX
OIL DIP STICK

NOTICE
Once oil has been added, a visual check should show oil about
1-2 threads from running out of the fill hole.
If using the dipstick to check oil level, DO NOT screw in the
dipstick while checking.

NOTICE
Check oil often during the break-in period. Refer to the
Maintenance section for recommended service intervals.
 CAUTION
The engine is equipped with a low oil shut-off and will stop
when the oil level in the crankcase falls below the threshold
level.

NOTICE
The first 5 hours of run time is the break-in period for the
engine. During the break in period, it is recommended to use
standard automotive, non-synthetic blended oils. After the
break-in period, synthetic oil can be used but is not required.
Adjusting throttle setting will increase/ decrease engine speed
helping to seat piston rings. Avoid bogging or lugging the
engine down and avoid prolonged running at constant RPM.
After the 5-hour break-in period, change the oil.

NOTICE
Synthetic oil may be used after the 5 hour initial break-in
period. Using synthetic oil does not decrease the recommended
oil change interval. Full synthetic 5W-30 oil will aid in starting
in cold ambient < 41º F (5º C).

NOTICE
Weather will affect engine oil and engine performance. Change
the type of engine oil used based on weather conditions to suit
the engine needs.
Add Fuel
Use clean, fresh, regular unleaded gasoline with a minimum
octane rating of 87 and an ethanol content of less than 10% by
volume. ybc
DO NOT mix oil with gasoline.
1. Place the water pump on a flat, level surface.
2. Remove the gasoline cap.
3. Slowly add gasoline to the tank. DO NOT OVERFILL. Gasoline
can expand after filling. A minimum of ¼ in. (6.4 mm) of
space left in the tank is required for gasoline expansion,
although more than ¼ in. (6.4 mm) is recommended. Gasoline
can be forced out of the tank as a result of expansion if
overfilled, and can affect the stable running condition of the
water pump. The approximate fuel level is shown on the fuel
gauge on top of the fuel tank.
