NOTES

Adjust the throttle linkage so that the engine 
stops  when  the  throttle  stick  and  trim  lever 
on  the  transmitter  are  fully  retarded. 
Alternatively, the engine may be stopped by 
cutting off the fuel supply. Never try to stop 
the engine physically.

Take  care  that  loose  clothing  (ties,  shirt 
sleeves,  scarves,  etc.)do  not  come  into 
contact with the propeller.Do not carry loose 
objects (such as pencils, screwdrivers, etc.) 
in  a  shirt  pocket  from  where  they  could  fall 
through the propeller arc.

Do  not  start  your  engine  in  an  area 
containing loose gravel or sand. 
The  propeller  may  throw  such  material  in 
your face and eyes and cause injury.

For  their  safety,  keep  all  onlookers 
(especially  small  children)  well  back  (at 
least  20  feet  or  6  meters)  when  preparing 
your  model  for  flight.  If  you  have  to  carry 
the  model  to  the  take-off  point  with  the 
engine  running,  be  especially  cautious. 
Keep  the  propeller  pointed  away  from  you 
and walk well clear of spectators.

Warning!  Immediately  after  a  glowplug-
ignition  engine  has  been  run  and  is  still 
warm, conditions sometimes exist whereby 
it is just possible for the engine to abruptly 
restart  if  the  propeller  is  casually  flipped 
over  compression  WITHOUT  the  glowplug 
battery  being  reconnected.  Remember  this 
if  you  wish  to  avoid  the  risk  of  a  painfully 
rapped knuckle!

This  engine  is  ideally  suited  to  a  variety  of  R/C 
aircraft,  including  trainer,  sports,  aerobatic  and 
scale types.
A  separate  precision-made  needle-valve  unit  is 
installed  at  the  rear,  where  manual  adjustment  is 
safely remote from the rotating propeller.
The  needle-valve  assembly  can  be  installed  either 
horizontally or vertically.

INTRODUCTION

With these engines, the piston will feel tight at the 
top  of  its  stroke  when  the  engine  is  cold. This  is     
normal. The  piston  and  cylinder  are  designed  to 
achieve  a  perfect  running  clearance  when  they 
reach their intended running temperature.

Note :

Carefully  insert  plug,  with 
washer, fingertight only, before 
final tightening with the correct 
size plug wrench.

BEFORE INSTALLING THE ENGINE

Installing the glowplug

Connect  the  short  length  of  fuel  tubing  (supplied) 
securely  between  the  needle-valve  outlet  and 
carburetor inlet as shown in the illustration on the next 
page.
In  the  event  of  the  tubing  becoming  damaged,  it 
should  be  replaced  with  54-56mm  length  of  5mm 
ODx2mm  ID  silicone  tubing.  Use  similar  material  to 
connect the fuel inlet nipple to the fuel tank.
