INSTRUCTIONS FOR MAX- BGX-1 RING REMOTE NEEDLE VERSION ENGINES
It is of vital importance, before attempting to operate
your engine, to read the general 'SAFETY INSTRUC-
TIONS AND WARNINGS' leaflet enclosed. Also, please
study the entire contents of the instruction manual
enclosed, so as to familiarize yourself with the con-
trols and other features of the engine.
This 'RN' version of the MAX-BGX-1 RING is fitted, as standard,
with a 'remote' needle-valve, mounted at the back of the engine,
safely distanced from the propeller. This device was origonated
by OS several years before being adopted by a number of other
manufacturers.
BEFORE INSTALLING THE ENGINE
Connect the needle-valve to carburettor jet nozzle with silicone
tubing supplied. In the event of the tubing becoming damaged,
it should be replaced with 78mm length of 5mm ODX2mm ID
silicone tubing.
The specifications are subject to alteration for improvement without notice.
