O.S. Engines 21RG-MX - Manual (Page 6)

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.
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 it is rotated over compression
WITHOUT the glowplug battery being
reconnected.
NOTES
•
•
•
•
If your engine is fitted with a recoil starter,
pull the operating handle straight out when
starting the engine, so that the cord does
not rub against the hull or engine.
This will help prevent the cord from being
damaged by abrasion or engine heat.
•
Do not extend the starter cord more than
45cm (18"). Do not abruptly release the
operating handle.
Allow the cord to rewind smoothly while still
holding the handle.
Do not attempt to disassemble the recoil
starter (if fitted). If you do so, the very
strong spring inside will be suddenly
ejected. This can be very dangerous.
