1. INFORMATION  

 

1.1 SAFETY 

 
Gasoline is extremely flammable and is explosive under certain conditions. 
Do not smoke or allow sparks or flames in your work area. 
Never run the engine in a closed area. The exhaust contains poisonous carbon monoxide gas that may 
cause loss of consciousness and lead to death. 
 
The battery electrolyte contains sulfuric acid. Protect your eyes, skin and clothing. If you spill the 
electrolyte on your skin or in your eyes, flush thoroughly with water. Call a doctor if electrolyte gets in 
your eyes.
