7)

 

Periodically check that the engine is firmly fixed to the engine mounts. Never start a loose 
engine! 

8)

 

Always use a balanced propeller! Always replace the propeller when damaged! 

9)

 

Make sure that no part of your body intersects the plane of the spinning propeller. 

10)

 

Always  wear  close-fitting,  well-fastened  clothes  when  starting  or  operating  the  running 
engine. Never wear loosely hanging clothes (tie, scarf, etc.).
