It is of vital importance, before attempting to operate your engine, to read the general 'SAFETY INSTRUCTIONS AND WARNINGS' section on pages 2-4 of this booklet and to strictly adhere to the advice contained therein. Also, please study the entire contents of this instruction manual, so as to familiarize yourself with the controls and other features of the engine. Keep these instructions in a safe place so that you may readily refer to them whenever necessary.
WARNINGS SAFETY INSTRUCTIONS AND WARNINGS ABOUT YOUR O.S. ENGINE Never touch, or allow any object to come into contact with, the rotating propeller and do not crouch over the engine when it is running. Remember that your engine is not a " toy ", but a highly efficient internal-combustion machine whose power is capable of harming you, or others, if it is misused or abused. As owner, you, alone, are responsible for the safe operation of your engine, so act with discretion and care at all times.
NOTES Take care that the glow plug clip or battery leads do not come into contact with the propeller. Also check the linkage to the throttle arm. A disconnected linkage could also foul the propeller. After starting the engine, carry out any needle-valve readjustments from a safe position behind the rotating propeller. Stop the engine before attempting to make other adjustments to the carburetor.
ABOUT THE ENGINE This is an overhead valve four stroke cycle engine for model aircraft use. This engine has a largest displacement of 32.4cc in the FS series and is suitable for scale and sport models. STANDARD ACCESSORIES Glowplug TypeF Needle Valve Extension Cable Set The engine is equipped with an easy to adjust 80N carburetor which can be reversed 180° and supplied with a F-6010 silencer which produces the milder four stroke sound.
RELOCATION OF CARBURETOR CONTROLS 1. Remove the carburetor retaining screws and remove the silicone tube between the carburetor and cover plate. Then, pull out the carburetor gently from the intake manifold. Intake Manifold 2. Rotate the carburetor 180°and insert on the intake manifold straight and gently. Do not force at an angle or the O ring inside the carburetor may be damaged. Pull out the carburetor gently. 3. Re-install the retaining screws.
INSTALLATION Because the FS-200S is a powerful, large-displacement, single-cylinder four-stroke-cycle engines, it is essential to use very substantial engine mounting. Conventional wooden mounting beams should be of rigid hardwood and of at least 15mm or 5/8-in square section. How to fasten the mounting screws. 5mm steel nuts Spring washer or lock washer Make sure that the mounting beams are parallel and that their top surfaces are in the same plane. Tighten second nut firmly down onto first nut.
EXHAUST HEADER PIPE & SILENCER IInstall these in the following sequence. Screw the exhaust header pipe into the exhaust port until it “bottoms”, then unscrew it approximately 90 degrees,and secure with locknut. Screw the silencer onto the header pipe more than 10mm and maximum 30mm to achieve the desired exhaust angle and tighten the other locknut.
2. Install the prop to the engine shaft, followed by the retaining washer and prop nut and tighten firmly with a 14mm wrench. (not supplied). NOTE: Make a habit of always checking the tightness of the propeller before starting the engine. Remember that, especially with wooden propellers, there is a tendency for the material to shrink, or for it to be reduced by the serrated face of the drive hub. Retighten the propeller nut if necessary after loosening the Safety Propeller Locknut.
GLOWPLUG Since the compatibility of the glowplug and fuel may have a marked effect on performance and reliability, it is suggested to use the O.S. Type F plug when it is necessary to replace. Carefully install plug finger-tight, before final tightening with the correct size plug wrench. Glowplug life Particularly in the case of very high performance engines, glowplugs must be regarded as expendable items. However, plug life can be extended and engine performance maintained by careful use, i.e.
STARTING The FS-200S is not equipped with manual choke controls, as it is intended for use with an electric starter only. A high-torque electric starter not only makes starting the engine easier, it dispenses with the need for a choke valve by turning the engine over fast enough to prime the cylinder. Starting procedure is as follows: 7.
6. Following the initial running-in session, check for any looseness in the installation due to vibration, then allow the engine a period of moderately rich operation in flight. Note: Remember that, when the engine is not yet fully run-in, the carburettor cannot be expected to give its best response in flight. Abrupt operation of the throttle, for example, may cause the engine to stall.
MAINTENANCE Please pay attention to the matters described below to ensure that your engine serves you well in regard to performance, reliability and long life. The use of modern high-performance alcohol based model engine fuels, while promoting cooler running, improved antidetonation combustion and increased power, have the disadvantage of causing corrosion due to the acid byproducts of combustion. The use of nitromethane in the fuel can also contribute to the problem.
