IMPORTANT-READ THIS BEFORE RUNNING
Running nitro kit is fun and easy, but to make
this a safe and good experience you must
observe a few rules. This kit is extremely fast,
easily over 65KPH, and can seriously injure
someone if you are not careful.
Any running area you choose must be dry.
Do not run car near any water or wet dirt.
Remove air filter and cover carb. intake.
Remove fuel from tank and fuel lines
This kit is not a toy. Always run car with a
second person as a spotter and pitman.
Hot Parts-The pipe, manifold, engine and head
are very hot and will cause burns.
Rotating Parts-Keep hands away from the
drive train, wheels, and engine when engine
is running.
Radio-Check battery life before running the
car. The radio does not have full control of the
car with steering and/or throttle/brake, do not
run until corrected. Failure to correct this will
result in possible injury and damage to the
car or property. We strongly recommend
using a Failsafe.
Glow fuel-Do not leave the glow fuel
unattended with the lid off. Fuel contains
Methanol and Nitro Methane and is flammable
and poisonous.
Store fuel in cool ventilated location.
Refer to the glow fuel label for additional
precautions.
Fuel tank in the car-Never store fuel in car
tank, it will ruin the engine if left in tank.
Always turn off the car BEFORE turning off
the radio.

A WARRANTY ISSUE .
Turn off radio in the car
Put a few drops of after run in the engine to keep
it from rusting.
Clear oil and dirt from chassis with a
degreaser.
Squeeze fuel line and hold until engine stops.
With a rag, cover exhaust outlet.
Do not run on public streets. It is very easy to
have the car run over or be damaged by hitting
the curb.
Do not operate the car in tight confined
places. The car is very fast and will easily hit
something.

be able to drive it safely.
