NEEDLE-VALVE EXTENSION
The  needle-valve  supplied  with  this  engine  is 
designed  to  incorporate  an  extension  so  that, 
when  the  engine  is  enclosed  within  the 
fuselage, the needle-valve may be adjusted 
from  the  outside.  For  this purpose  a  Needle 
Valve Extension Cable Set is supplied with the 
engine. If a longer extension is reguired, cut a 
commercially  available  rod  to  the  required 
length,  bend  one  end  to  an  L  shape,  insert  it 
into  needle's  center  hole  and  secure  it  by 
tightening the set-screw in the needle-valve 
knob with 1.5mm Allen key.

INSTALLING SILENCER
E40400 Silencer
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!
The  exhaust  outlet  of  the  silencer  can  be 
rotated 90 degrees in the following manner:
Loosen the locknut and assembly screw.
Set the exhaust outlet at  the required posi-
tion by rotating the rear part of the silencer.
Re-tighten the assembly screw, followed by 
the locknut.
