1) Safety

These nitro powered engines require a great deal of care and caution

when working with them, during and around their operation.

Please pay attention to these safety precautions:

•The fuel needed for these engines is highly toxic, avoid skin and eye

contact and do not swallow it, also store it in a safe place well out of reach

of children.

•Fuel is highly flammable; avoid exposing fuel to open flames or sparks.

•Exhaust gases are hazardous. Avoid inhalation or eye contact.

•The engine cooling head, manifold and exhaust pipe may reach

temperatures over 100°C (212F), so always wear gloves when working on

a hot engine.

•Avoid contact with the moving or rotating parts of the engine while the

engine is running.

2) Parts and equipment related to the operation of a nitro engine

This section describes the parts, and equipment that you will be using

when you operate a model engine. This includes fuel, air-filter, carburetor,

glow plug, exhaust system, and starting equipment.

FUEL

Only use commercially available fuel formulated for model car engines. It

is advised to use our RB Concept Fuel whenever possible. In the event

you cannot find RB Concept Fuel we suggest that you follow the

recommendation of your dealer where you have purchased your engine.

Concept Fuel has been specially developed for this kind of engines and

can contain 10-25% nitro. RB Concept engines can be used originally with

a fuel-mixture of 25% nitro maximum. If you want to use a higher content

nitro fuel, then it is advised to de-compress the engine by adding an extra

0.1mm head shim between the combustion chamber and the cylinder.

Before using the fuel, shake the fuel bottle thoroughly to blend the oil and

nitro with the methanol. Do not leave the fuel bottle open for long periods,

as methanol quickly absorbs humidity from the air. This can deteriorate
