Install the prop to the engine shaft, followed by the retaining
washer and prop nut and tighten firmly with a 14mm
wrench. (not supplied).

3. Add the special tapered and slotted locknut and secure
with a 12mm wrench while holding the prop nut with the
14mm wrench. (not supplied).

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.
The locknut should be tightened firmly after retightening
the propeller nut.
NOTE:
Note:
Some spinners which are retained at the top of the cone
cannot be used with the prop locknut supplied with the
engine. In this case, optional locknut sets are available
from O.S. – Propeller Locknut Set for Spinner (Code
No.45910200 4mm) and (Code No.45910300 5mm).
Since the FS-200S-P is intended to be started with an electric
starter, the addition of a spinner assembly for centering the
starter sleeve is desirable. Special propeller locknut sets are
available for use with spinners.
Use a good quality well balanced spinner, enclosing the
propeller boss. Make sure that it is of precision-made and
sturdy construction so that the spinner shell cannot loosen
when the starter is used.
Make sure the spinner notches do not interfere the propeller.
If they do, cut the notches to clear.

The FS-200S-P should be operated on a methanol based fuel
containing not less than 18% castor-oil, or a top quality
synthetic lubricant (or a mixture of both), plus a small
percentage (5-30%) of nitromethane for improved flexibility
and power. The carburettor is adjusted at the factory for a fuel
containing 20% lubricant and 10% nitromethane.
Some commercial fuels also contain coloring additives as an
aid to fuel level visibility. In some cases, these additives have
indicated slightly negative effects on performance. We would
suggest that you use such fuels only if you are satisfied that
they do not adversely affect running qualities when compared
with familiar standard fuels.
When changing to a fuel brand or formula that is different
from the one to which you are accustomed, it is a wise
precaution to temporarily revert to in-flight running-in
procedures, until you are sure that the engine is running
entirely satisfactorily.
Reminders:
AII model engine fuel is poisonous.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.
Though not as volatile as gasoline, model engine fuel is
also highly inflammable.
Keep it away from an open flame, excessive heat, sources
of sparks, or anything else that might ignite it. Smoking is
firmly discouraged.
