Glow Plug Igniter
Pliers
Element glows when energized.
Replace the plug when the
element does not glow or is
burnt out.
WARNING
When checking the plug element hold the
plug with tools, such as pliers, etc.
Do not hold near your face or the fuel
remaining in the filament may burn you.
Check that the current to the glowplug is
switched off.
3.
To close the needle-valve, turn it
clockwise, while to open the
needle-valve, turn it counter-
clockwise. Turn the needle-valve
clockwise slowly until it stops.
This is the fully closed position.
4.
Open the needle-valve 2-2.5
turns from the fully closed
position and set the throttle in
the fully open position.
5.
Apply the starter and press the starter switch
for 5-6 seconds to prime the engine.
6.
Position the throttle stick at 2-3 scales
advanced from the fully pulled down position.
Turn the prop “backwards” (clockwise) by
hand until it is against compression. This is
to enable the kinetic energy of the prop to
subsequently assist the starter through the
compression stroke to start the engine.

Note:
Make sure that the throttle
linkage is made so that the
throttle is fully closed when
the throttle lever as well as
trim lever on the transmitter
are fully pulled down.
How to stop the engine
Pull down the throttle lever and trim lever on
the transmitter fully.
Now close the needle-valve gradually so
that the rpm increases.
10.
When the engine starts, slowly open the
throttle to the mid speed position. Then,
disconnect current to the glowplug. If at this
pint the engine stalls, it is probable that the
mixture is excessively rich. Close the
needle-valve a little and restart the engine.
9.
Make sure that the rotating direction of the
electric starter is correct. Energize the
glowplug and apply the starter.

RUNNING-IN (“Breaking-in”)
For long life and peak performance, every
engine needs special treatment when new,
know as “running-in” or “breaking-in”. This is a
procedure during which the engine is operated
under strictly controlled conditions at the
beginning of its life, in order to avoid the risk of
immediate damage to certain components
through becoming overheated or stressed and
to help working surfaces to become smoothed
and aligned for maximum mechanical
efficiency thereafter. With some engines, this
can require a tediously protracted period of
bench running, but, as O.S. engines are
manufactured to fine tolerances and from the
finest quality materials, a relatively brief
running-in period is sufficient and can be
completed with the engine installed in the
aircraft. Prolonged running with too rich
mixture and/or low speed will not complete the
proper running-in.
