LOSI 8IGHT/8IGHT-T RTR • INSTRUCTION MANUAL
Driving Precautions
• Always observe all warnings, precautionary statements and instructions
supplied by the fuel manufacturer/provider.
• Fuel is a fire accelerant. Never operate your vehicle near open flames. Never
smoke while operating your vehicle or while handling fuel.
• Always use caution when handling fuel.
• Always run your model engine in a well-ventilated area. Model engines produce
harmful carbon monoxide fumes.
• Always drain your engine after you have finished running your vehicle. Do not
store the vehicle with fuel in the fuel tank.
• Never handle model engines and mufflers until they have had time to cool.
They become extremely hot when in use.
• Always store your fuel in a safe place well away from sparks, heat or anything
that can ignite.
• Always ensure that fuel is stored in a clearly marked container well away from
the reach of children.
• Never allow fuel to come into contact with eyes or mouth. Fuels used in model
engines are poisonous.
• Never return unused fuel from the fuel tank back into the fuel container.
• Contact your local waste disposal authorities for more information about
discarding fuel waste responsibly.
Appropriate carburetor adjustment is critical when running a nitro-powered RC
vehicle. The fuel mixture is “rich” when there is too much fuel and “lean” when
there is not enough fuel for the amount of air entering the engine. Using a flat-head
screwdriver, adjust the high- and low-speed needles to control the amount of fuel
entering the engine. The low-speed needle is located in the front of the moving slide.
The high-speed needle sticks straight up at the back of the carburetor. Turn the
needle counterclockwise for a richer air/fuel mixture and clockwise for a leaner air/
fuel mixture. An overly rich mixture will yield sluggish acceleration and performance
with thick smoke from the exhaust. A lean mixture can cause the engine to hesitate
before accelerating or, in some cases, to lose power momentarily after the initial
acceleration. A lean mixture also makes the engine run too hot and does not provide
enough lubrication for the internal engine components, causing premature wear and
damage.
Run the engine slightly rich
and
never lean
to avoid overheating and
possible damage. See:
Vehicle Tuning

Fuel Safety and Use Instructions
Fueling the Vehicle
Understanding Rich and Lean Fuel Mixture
Lift the fuel tank cap and fill the fuel tank. Press the fuel tank cap down securely.
WARNING:
Fuel is highly flammable. Always follow all safety precautions
during use.
• Maintain sight of the vehicle at all times.
• Inspect the vehicle for loose wheel hardware.
• Inspect the steering assembly for any loose hardware.
• Stop driving the vehicle when you notice a lack of power. Driving the vehicle
when the battery is discharged can cause the receiver to power off. You may
lose control of the vehicle.
• Do not apply the throttle in forward if the vehicle is stuck. Applying throttle in
this instance can damage the engine.
• Allow the engine to cool to ambiant temperature between runs.
Starting Procedure

2. Turn on the receiver.
3. Lock the glow igniter onto the glow plug.
4. Pull the starter cord in a quick continuous motion to start the engine. Do not pull the starter cord over 6 inches.
