NOTES WHEN APPLYING
AN ELECTRIC STARTER
Do not over-prime. This could
cause a hydraulic lock and damage
the engine on application of the
electric starter.
If over-primed, remove glowplug,
close needle-valve and apply
starter to pump out surplus fuel.
Cover the head with a rag to
prevent pumped out fuel getting
into your eyes.

INTRODUCTION
THE MAX-10LA,15LA,25LA have been developed to
meet the requirements of beginners and sport
flyers. Of modern design and having a separate
needle-valve unit mounted at the rear, where
manual adjustment is safely remote from the
rotating propeller, they offer the advantages of
reliability and easy handling, at lower cost. Like all
O.S. engines they are built to standards of
engineering excellence that have evolved through
more than 60 years' experience in the design and
production of model internal-combustion engines.
Advanced modern precision machinery, top quality
materials and the efforts of highly skilled craftsmen
and technicians are combined to ensure a
continuation of the levels of performance,
durability and reliability for which O.S. is world
famous.
The 'midnight blue' external finish may be
decolorized by very high surface temperature or
by certain solvents. Such decolorization does not
affect engine perfor-mance, however.

Connect the short length of fuel tubing supplied
securely between the fuel outlet and the fuel inlet. In
the event of the tubing becoming damaged, it should
be replaced with a suitable length of best quality 5mm
ODX2mm ID silicone tubing. Use similar material to
connect the fuel inlet nipple to the fuel tank.
