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.
■
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.
