ENGINE SAFETY PRECAUTIONS

Failure to follow these safety precautions may result 
in severe injury to yourself and others.

Keep all engine fuel in a safe place, away from high heat, 
sparks or fl ames, as fuel is very fl ammable. Do not smoke 
near the engine or fuel; and remember that engine exhaust 
gives off a great deal of deadly carbon monoxide. Therefore, 
do not run the engine in a closed room or garage.

Get help from an experienced pilot when learning to operate 
engines. 

Use safety glasses when starting or running engines.

Do not run the engine in an area of loose gravel or sand; the 
propeller may throw such material in your face or eyes.

Keep your face and body as well as all spectators away from 
the plane of rotation of the propeller as you start and run
the engine.

Keep these items away from the prop: loose clothing, shirt 
sleeves, ties, scarves, long hair or loose objects such as 
pencils or screwdrivers that may fall out of shirt or jacket 
pockets into the prop.

Use a “chicken stick” or electric starter to start the engine. 
Do not use your fi ngers to fl ip the propeller. Make certain the 
glow plug clip or connector is secure so that it will not pop off 
or otherwise get into the running propeller. 

Make all engine adjustments from behind the rotating propeller.

The engine gets hot! Do not touch it during or right after 
operation. Make sure fuel lines are in good condition so fuel 
will not leak onto a hot engine, causing a fi re.

To stop a glow engine, cut off the fuel supply by closing 
off the fuel line or following the engine manufacturer's 
recommendations. Do not use hands, fi ngers or any other 
body part to try to stop the engine. Do not throw anything into 
the propeller of a running engine.
