Fuel is combustible and therefore must be kept in an enclosed container at a safe distance from the
engine when it is running.
15)
When preparing fuel carefully follow the manufacturer’s or dealer’s instructions.
16)
Small objects must be kept at a safe distance from the engine when it is running. Never throw any

19)
When starting the engine make sure that bystanders, especially children, are at a safe distance of at
least 10 m.

The engine power output makes it possible to fly big models. Mal-operation of such models may
cause serious damage. Start using the MVVS 58 in model planes only after you have mastered
operating smaller models.
