Safety Instructions 

 

                                

READ THIS! 

 

WARNING!

 

This motor can cause severe harm to you, and/or others, if misused, or if these safety 
precautions and instructions are not observed.  Desert Aircraft is not responsible for 
any loss, injury or damage resulting from the miss-use of its products.  

 

You alone are responsible for the safe operation of your motor.  

 

This motor can stop at any time, for a variety of reasons. Do not fly your plane in such 
a way that damage or harm will result if the motor stops running. If you cannot fly your 
plane safely if the motor stops running for any reason, do not fly the plane.  
 

 

  Do not operate this motor if you do not want to be completely responsible for any damage or injury 

incurred or caused during its operation.

 

  Read all instructions before operating your motor.

  

  If you have any questions about any aspect of operating this motor, do not attempt to start or 

operate it.

 

 

Never operate the motor, or fly, alone

 

  When operating the motor, never stand, or allow anyone else to stand, in front of, or to the side of 

the propeller.  Always stand behind the propeller.

 

  Keep away from the prop while operating the motor.  Do not wear loose clothing near the motor or 

prop. Do not run the motor near loose material such as dirt, gravel, power cords, ropes, sand, etc.  
Loose material can be drawn into the turning prop causing injury or damage. 

  Always operate the motor in an open area.  Do not operate indoors. 

  This motor can develop tremendous thrust.  Make sure the aircraft is properly secured when starting 

or operating the motor. 

  Inspect motor mount bolts and firewall integrity before operating the motor. 

  Anyone in the immediate area of the motor should use eye protection during operation of the motor.

 

  Keep spectators at least 30 feet away when operating the motor.

 

  Turn off the motor before making any adjustments.

 

  Always use the correct length propeller bolts. Do not use spacers behind the propeller.   

  Spinner cones must not touch the propeller.

 

  Thinner props may require using shorter prop bolts, especially if not using a spinner back plate.  

Make sure your prop bolts do not bottom out in the propeller hub. 

 

  Check that the propeller bolts are tight before every flight.

 

  Always install an ignition kill switch to stop the motor.

 

  Adjust the carburetor linkage so that the motor will stop when the carburetor is completely closed.

 

  Gasoline is extremely flammable.  Be careful of any sparks from electrical contacts such as fuel 

pumps, battery chargers, etc.  Do not allow smoking in the area of your fuel supply or motor.  Store 
fuel in approved containers and in well ventilated areas.

 

  Allow the motor to cool before touching or fueling.

 

  Always flip the prop a few revolutions after running the motor to discharge the ignition system.

 

  The ignition system develops extremely high voltage. Do not touch it during operation.              

 

  Never use a damaged, modified, or repaired prop, or a prop that has struck the ground or any other 

object.  Damage that can be hard to see, could turn into disaster when the prop is turning at 
thousands of RPM.
