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 q

Do not fill above the top of the fuel filter screen (marked w),
or the fuel may overflow when it heats up later and
expands.
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.

4. ELECTRIC STARTER MODELS

For electric starter operation, proper electric wiring
arrangements are needed before normal engine operation.
1. BATTERY
Use a battery rated 12V 24AH or larger.
WARNING
Charge the battery in a fully ventilated location.
Batteries generate hydrogen gas, which can be
highly explosive. Do not smoke or allow flames or
sparks near a battery, especially during charging.
Be sure to confirm Battery polarity. Connect positive
(+) terminal first when mounting battery, and
disconnect negative (- ) terminal first when
dismounting.
Battery electrolyte contains sulphuric acid. Protect
your eyes, skin and clothing. In case of contact, flush
thoroughly with water and get prompt medical
attention, especially if your eyes are affected.
2. BATTERY CABLE
Use a proper cable and ground wire to connect battery.
For GROUND WIRE, use a flat braided wire of 20 sq.
mm. or larger sectional area.
