Oil Recommendations
Before starting engine, fill with oil, refer to viscosity
chart in Figure 2-2. Engine oil capacity is 600 ml. Do not
over-fill. Use a 4-stroke, or an equivalent high detergent,
premium quality motor oil certified to meet or exceed
U.S. automobile manufacturer’s requirements for service
classification SG, SF. Motor oils classified SG, SF will
show this designation on the container.
IMPORTANT: DO NOT use nondetergent oil or
2-stroke engine oil. It could shorten the engine’s
service life.

Insert the cap/dipstick into the oil filler neck, but do
not screw it in.
Remove the oil filler cap/dipstick. If the level is low,

Fuel Recommendations
Use automotive gasoline (unleaded or low leaded to
minimize combustion chamber deposits) with a minimum
of 87 octane. Gasoline with up to 10% ethanol or 15%
MTBE (Methyl Tertiary Butyl Ether) can be used. Never
use an oil/gasoline mixture or dirty gasoline. Avoid
getting dirt, dust, or water in the fuel tank. DO NOT use
E85 gasoline.

Refuel in a well-ventilated area with the engine
stopped. Do not smoke or allow flames or sparks
in the area where the engine is refueled or where
gasoline is stored.
Do not overfill the fuel tank. After refueling, make
sure the tank cap is closed properly and securely.
Be careful not to spill fuel when refueling. Spilled
fuel or fuel vapor may ignite. If any fuel is spilled,
make sure the area is dry before starting the engine.
Avoid repeated or prolonged contact with skin or
breathing of vapor.
