NOTE
Engine shipped from our factory is without oil.
Before starting engine, fill with oil. Do not over-fill.
1. CHECK ENGINE OIL (See Fig.
2
)
Before checking or refilling engine oil, be sure the engine is
located on stable, level surface and stopped.
■ Do not screw the oil gauge into the oil filler neck to check oil
level. If the oil level is low, refill to the upper level with the
following recommended oil.
■
Use 4-stroke automotive detergent oil of API service class
SE or higher grade.
■
Select the viscosity based on the air temperature at the
time of operation as shown in the table. (See Fig.
2
-
①
)
CAUTION
Air cooled engines run hotter than automotive
engines.
The use of non-synthetic multi-viscosity oils
(5W-30, 10W-30, etc.) in temperatures above
40°F(4°C) will result in higher then normal oil
consumption. When using a multi-viscosity oil,
check oil level more frequently.

Do not refuel while smoking, near an open flame
or other such potential fire hazards. Otherwise
fire accident may occur.

■
Stop the engine and open the cap.
■ Close the fuel valve before filling the fuel tank.
■ Do not fill above the top of the fuel filter screen
(marked
❶
), or the fuel may overflow when it heats up later
and expands.
For electric starter operation, proper electric wiring
arrangements are needed before normal engine operation.

■ When filling the fuel tank, always use the fuel filter screen.
■
After refueling, tighten the fuel cap (rotate clockwise) until
it makes a physical stop, there will be a relief in resistance
just before the physical stop.
This will form a vapor seal between the tank and fuel cap.
■
Wipe off any spilled fuel before starting the engine.
