DO NOT USE HANDS, FINGERS
OR ANY OTHER PART OF THE
BODY TO STOP THE  
PROPELLER. 
DO NOT THROW ANY OBJECT
INTO A PROPELLER TO STOP
IT!

8. Discard any propeller that is
nicked, scratched, cracked or
damaged in any way.

I

T IS HIGHLY RECOMMENDED THAT

:

1. Safety glasses or goggles be
used when starting and running
your engine.

2. You do not run the engine in
the vicinity of loose gravel or
sand. The propeller may throw
such materials into your eyes. The
engine may also ingest these
harmful materials.

3. Loose clothing should be
avoided when operating your
model engine. Loose clothing can
become entangled in the propeller,
creating the possibility of bodily
harm. Also, all loose objects
(screwdrivers, pencils, nickel cad-
mium starters, etc.) should be
removed from your pockets so

they do not fall into the propeller.

4. Glow plug clips and cords are
kept away from the propeller.

5. Your glow fuel is kept in a safe
place well away from sparks, heat
or anything that may ignite the
fuel.

B

EWARE

:

1. Model engines get very hot
while running. Do not attempt to
handle the engine until it has
cooled.

2. Always run your model engines
in a well-ventilated area. Similar
to automotive engines, model
engines produce possibly harmful
carbon monoxide fumes.

3. Remember that model engines
produce a substantial amount of
power, more than enough to seri-
ously injure people and/or do con-
siderable damage to property.
Always use common sense, skill
and constant observation of safety
precautions.
