Engine Cooling

The engine is air cooled. Air must circulate freely

which can contribute to improper cooling.

blower housing removed - this will cause

overheating and engine damage.

or egg or vegetable oil. Call a physician

immediately.

Every 25 hours or each week check electrolyte

level of each cell by removing caps one at a time.

The electrolyte level should be at level indicator.

Use distilled water to fill each cell if needed. In

To clean, remove spark plug from engine, scrape

electrodes (DO NOT wire brush or sand blast).

NOTE: Sparking can occur if wire terminals do

not fit firmly on spark plugs. Reform terminals if
