thoroughly to obtain the correct set­up and the safest, 

most rewarding operation of your Arrow Shark RC Boat. 

Please study the manual carefully before attempting to

Safety Precautions 

* This is a high performance radio controlled boat ­ it is not a toy. Adult supervision is 
required  for  children  who  should  be  warned  about  the  dangers  of  playing  with  gas 
engines, fast spinning propellers and of being in close proximity to water. 
*  This  boat  is  controlled  by  radio  signals  which  are  susceptible  to  possible 
interference  from  other  transmitters,  paging  systems  and  other  sources  of  electrical 
noise.  Before  turning  on  your  radio  transmitter  and  receiver,  make  sure  that  no  one 
else in the area is operating a radio on the same frequency (channel). 
* After turning on your radio, watch it carefully to ensure that it is operating correctly 
and  not  being  affected  by  interference.  Carry  out  a  range  check  as  advised  by  the 
radio manufacturer to ensure you will be able to maintain control of your boat at your 
planned maximum operating distance. 
*  Always  fit  a  "Fail  Safe"  device  so  that  your  engine  is  stopped  should  the  radio 
encounter  interference, go out of range or have  its battery go flat. Some radios  have 
inbuilt Fail Safe systems, but others do not. They can be purchased separately at any 
good hobby shop. 
* When the engine  is running, the propeller  can  spin at high speed. Never  touch the 
propeller  anytime the engine  is running. Be very  careful that  any item such as  loose 
clothing, shirtsleeves, ties, scarves, long  hair or anything else does not  get  anywhere 
close to the propeller, even when  it  is stationery.  If the clutch engages, the propeller 
can  start  to  spin  without  warning  and  loose  clothing  etc  can  become  entangled  and 
cause injury. 
*  The  speed  and  mass  of  this  boat  can  inflict  property  damage  and  severe  personal 
injury if a collision occurs. Never run this boat in the presence of swimmers or where 
the possibility of collision with people or property exists. 
*  Model  engines  generate  considerable  heat.  Do  not  touch  any  part  of  your  engine 
until it has cooled. Touching the cylinder head or any part of the exhaust system may
