BREAKING IN (RUNNING IN)
ENGINE
Your new engine requires a period of
break-in (running-in) to allow mating sur-
faces of moving parts to wear-in evenly.
Correct break-in (running-in) will help
ensure proper performance and longer
engine life.
cC
Failure to follow the break-in (running-in)
procedure may result in reduced engine
life or even severe engine damage.
