W ARNINGS Model engine fuel is poi- sonous. Do not allow it to come into contact with the eyes or mouth. Always store it in a clearly marked container and out of the reach of children. Model engine fuel is also highly flammable. Keep it away from open flame, excessive heat, sources of sparks, or anything else which might ignite it.
This engine is intended for model cars. Do not attempt to use it for any other purpose. Mount the engine in your model securely , following the manufacturers' recommendations, using appropriate screws and locknuts. Fit an effective silencer (muf fler).
NOTES To stop the engine, fully retard the throttle stick and trim lever on the trans-mitter, or, in an emergency, cut off the fuel supply by pinching the fuel delivery tube from the tank.
INSTALLING THE GLOWPLUG Carburetor NOTE: With this engine, the piston will feel tight at the top of its stroke when the engine is cold. This is normal. The piston and cylinder are designed to achieve a perfect running clearance when they reach their normal running temperatures.
ENGINE INST ALLA TION Make sure that the vehicle's engine mounting surfaces are level and in the same plane. Poor installation may cause distortion of the crankcase, bearings, etc., resulting in erratic running and loss of performance. The recommended screws for securing the engine are 3mm or 4-40 steel Allen hexagon socket type.
ー8ー This is a heavy-duty wet type air cleaner that has been developed specifically for the O.S. MAX-CV series model car engines. It contains specially impregnated filter elements which prevent .

Glowplug life Particularly in the case of very high performance engines, glowplugs must be regarded as expendable Install a plug suitable for the engine. Use fuel containing a moderate percentage of nitromethane unless more is essential for racing events.
Apart from when actually burned out, a plug may need to be replaced because it no longer delivers its best performance, such as when: When to replace the glowplug Filament surface has roughened and turned white. Filament coil has become distorted. Foreign matter has adhered to filament or plug body has corroded.
LONG SOCKET WRENCH SILICONE TUBING Heatproof silicone tube of approx. 5mm o.d. and 2mm i.d. is required for the connection between the fuel tank and engine. FUEL BOTTLE OR PUMP ELECTRIC ST ARTER AND ST ARTER BA TTER Y Use an electric starter with 12-volt battery for starting the MAX-12CV .
CARBURETOR CONTROLS ( 10E-R ) The Needle-Valve: The Mixture Control Screw: The Throttle Stop Screw: Three adjustable controls are provided on this carburetor.
approx 1mm Approx. 0.3-0.5mm The following procedure is suitable for these engines when the O.S. T-1020 tuned silencer and a fuel containing up to 30% nitromethane are used. Use the same fuel as is to be employed for all initial running and containing NOT LESS THAN 18% lubricant.
30º When the engine starts, first allow it to operate in short runs at the very rich starting settings, with the glowplug battery still connected and with its driving wheels clear of the ground.The rich mixture will, under these conditions, provide adequate lubrication and cooling, indicated by profuse smoke from the exhaust.
IF THE ENGINE F AILS TO ST ART Check the following: Glowplug battery discharged or glowplug defunct. Fuel not reaching carburetor. Engine flooded. Do not over-prime. (This could also cause hydraulic lock and damage the engine on application of the electric starter.
In this case, turn the Mixture Control Valve clockwise 45~90˚. If, on the other hand, the engine tends to speed up momentarily and then cut out abruptly when the throttle is opened,the idling mixture is too lean. Correct this by turning the Mixture Control Valve counter-clockwise 45~90˚.
BALL LINK AND SLIDE VALVE EXTENSION It is seldom necessary to separate the slide-valve extension from the slide-valve itself. For cleaning, withdraw this complete sub-assembly from the carburetor body after removing the slide-valve guide screw. Then wash with methanol or glow-fuel.
4. CARE AND MAINTENANCE 1. 2. 3. The minute particles of foreign matter, that are present in any fuel may, by accumulating and partially obstructing fuel flow, cause engine performance to become erratic and unreliable. O.S. 'Super-Filters' (large and small) are available, as optional extras, to deal with this problem.
