length. Slowly return the recoil starter
rope (3) again so that it is rolled up
again.

starts.
Start procedure when the engine is
warm:
Avoid damage to the machine!
The primer must no longer be
pressed when the engine is warm.
It should be remembered, however,
that the engine can cool down very
rapidly in very cold weather.

the primer (1).
