O.S. engine FS-30S Owner's Instruction Manual page 4

Adjust the throttle linkage so that the engine
stops when the throttle stick and trim lever
on the transmitter are fully retarded.
Alternatively, the engine may be stopped by
cutting off the fuel supply. Never try to stop
the engine physically.
Take care that loose clothing (ties, shirt
sleeves, scarves, etc.)do not come into
contact with the propeller.Do not carry loose
objects (such as pencils, screwdrivers, etc.)
in a shirt pocket from where they could fall
through the propeller arc.
Do not start your engine in an area
containing loose gravel or sand.
The propeller may throw such material in
your face and eyes and cause injury.
This manual handles the following two versions.
FS-30S, FS-40S
The FS Series engines are up-to-date
overhead-valve four-stroke-cycle engines for
model aircraft use and are the outcome of a
long period of technical development.
The FS Series engines are produced by the
world's oldest and largest model engine
manufacturing company; a company which
also pioneered the quantity production of
model four-cycle engines.

INSTALLING THE GLOWPLUG
Install washer on glowplug and
insert carefully into cylinder-head,
making sure that it is not cross-
threaded before tightening firmly.
NOTES
For their safety, keep all onlookers
(especially small children) well back (at
least 20 feet or 6 meters) when preparing
your model for flight. If you have to carry
the model to the take-off point with the
engine running, be especially cautious.
Keep the propeller pointed away from you
and walk well clear of spectators.
Warning! Immediately after a glowplug-
ignition engine has been run and is still
warm, conditions sometimes exist whereby
it is just possible for the engine to abruptly
restart if the propeller is casually flipped
over compression WITHOUT the glowplug
battery being reconnected. Remember this
if you wish to avoid the risk of a painfully
rapped knuckle!
