TRAKFAST REPAIR MANUAL

Rev. 09/07

Combustion

Depressing the trigger activates the ignition circuit. 

This causes a spark (N) to jump the gap between 

the spark element and cylinder head, igniting the 

fuel/air mixture in the combustion chamber. Pis-

ton assembly (O) is forced downward driving the 

fastener into the work surface.
