OPERATION
GAS AND OIL FILL-UP
The engine comes shipped without oil or gasoline. Be sure to add oil and gasoline before starting the
engine.
1. Add oil before starting mower for the first time.
2. Service the engine with gasoline as instructed.
Warning: Use extreme care when handling gasoline. Gasoline is extremely flammable
and its vapors are explosive. Never fuel the machine indoors or while the engine is hot or
running. Extinguish all cigarettes, cigars, pipes and other potential sources of ignition.
Engine Oil
Engine oil is a key factor in deciding the engines performance. Do not apply engine oil with
additives or 2-stroke gasoline engine oil, because they haven’t enough lubrication, and may shorten
the engines service life.
Check the engine with it stopped on a level ground.
Engine oil recommended: 10W-30
As viscosity varies with regions and temperatures, SF class oil is recommended.
Check method
1. Remove the dipstick and Clean it.
2. Reinsert the dipstick into the oil filling hole, and insert it to the end.
3. Check the oil level: If the oil level is too low, add the recommended engine oil and make sure the
oil level between upper level(1) and lower level(2).
4. Re-install the dipstick.
Adding Gasoline
1. Remove the fuel tank cap and check fuel level.
2. If the level is too low, refuel the tank, remember adding fuel not
over the fuel upper level.
Warning:
1. Gasoline is extremely flammable and is explosive under certain conditions.
2. Refueling in a well-ventilation area with the engine stopped. Do not smoke and allow flames or
sparks in the area where gasoline is stored or where the fuel tank is refueled.
