• Always stand behind the propeller when making 

carburetor adjustments.

• Always wear safety glasses or goggles when start-

ing and running your engine.

• Always keep your fuel in a safe place well away 

from sparks, heat or anything that can ignite.

• Always ensure the aircraft is secure and will not 

move once the engine is started.

• Always rebind your transmitter to your receiver(s) 

after setup and before first flight.

• Always ensure the throttle failsafe is set to low 

throttle in your transmitter.

• Always perform a range check prior to flight. 

• Always cut off the fuel supply (pinch or disconnect 

the fuel line to the carburetor) or use the throttle 
linkage to shut off the air in order to stop the 
engine.

• Always ensure gasoline and fuel  are stored in a 

clearly marked container well away from the reach 
of children.

• Never use hands, fingers, or any other body part to 

stop the propeller.

• Never throw any object into a propeller to stop it.

• Never run the engine in the vicinity of loose small 

objects, such as gravel or sand, to avoid the pro-
peller uncontrollably throwing such materials. 

• Never wear loose clothing or a loose neckstrap 

when operating your model engine as these  items 
could become entangled in the propeller.

• Never have loose objects such as screwdrivers, 

pencils etc. in your pockets when operating your 
model engine. These could fall into the propeller.

• Never allow fuel to come into contact with eyes 

or mouth.  Gasoline and other fuels used in model 
engines are poisonous.

Precautionary Guidelines

• Always mount the engine securely on a bench 

mount or high-quality engine mount.

• Always use the correct size and pitch of propeller 

for your engine. Refer to Propeller Chart in this 
manual.

• Always confirm proper balance of your propeller 

prior to installation of the engine. Failure to do 
so could cause damage to the engine and/or the 
airframe.

• Always utilize an electric starter to start your 

engine.

• Always discard any propeller that is nicked, 

scratched, cracked or damaged in any way.

• Always run your model engine in a well-ventilated 

area. Model engines produce possibly harmful 
carbon monoxide fumes.

• Always store your fuel safely in a sealed, water-

resistant container. 

• Always store fuel in a cool, dry location. Do not al-

low fuel  containers to come in direct contact with 
concrete, as the fuel may absorb moisture.

• Always responsibly discard fuel if there is conden-

sation and/or water inside the fuel container.

• Never return unused fuel from the fuel tank back 

into the fuel container.

• Never attempt to repair or modify a propeller 

beyond its intended use.

• Never handle model engines, mufflers and/or 

tuned pipes until they have had time to cool. They 
become extremely hot when in use.
