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.

Failure to follow the break-in (running-in)

procedure may result in reduced engine

life or even severe engine damage.

Break-in (running-in) premix ratio:

Refer to “Gasoline/Petrol and Oil

Mixing”.

Break-in (running-in) time: 10 hours
