The angled exhaust of the silencer can be
rotated to any desired position in the following
manner:
1) Loosen the locknut and assembly screw.
2) Set the exhaust outlet at the required
position by rotating the rear part of the
silencer.
3) Re-tighten the assembly screw, followed by
the locknut. The standard silencer is quite
effective but reduces power to some degree.
INSTALLATION OF SILENCER
Assembly screw
Cone baffle
Turn to requlred position
Exhaust outlet
Locknut
Exhaust pressure nipple
It is recommended to seal the fitting faces of
engine exhaust and silencer with silicone
sealant.
Model engines generate considerable heat.
Do not touch any part of your engine until
it has cooled. Contact with the muffler
(silencer), cylinder head or exhaust header
pipe, in particular, may result in a serious
burn. Keep your hands and face away from
exhaust gas or you will suffer a burn.
Reminder!

BEFORE STARTING
Tools, accessories, etc.
The following items are necessary for operating the
engine.
Fuel
Model glowplug engine fuel of good quality, preferably
containing a small percentage of nitromethane. (See
"Advice on selection of fuel, glowplug and propeller")
Propeller
Suggested size is 7x4(10LA), 8X4 (15LA), or 9X5
(25LA).
1.5 volt heavy-duty
dry battery
or 2 volt rechargeable
lead-acid cell (at least 5Ah)
If a 2-volt cell is employed,
use a resistance wire, as
shown, to reduce applied
voltage, otherwise element
will overheat and burn out.
Resistance coil
(nichrome wire)
Adjust applied voltage by changing the position of clip on
resistance coil until glowplug element is glowing bright red.

Fuel tank
For installation in the model, a 70cc(2.5oz.) for 10LA,
a 100cc(3.5oz.) for 15LA, a 150cc(5oz.) for 25LA tank,
is suggested.
Glowplug battery
The power source for heating the glowplug may be
either a large heavy-duty 1.5volt dry cell, or preferably,
a 2-volt rechargeable lead-acid cell (accumulator).
