Refer to the photo at left to familiarise yourself with your engine's carburettor. 
All of the carburettor settings come preset from the factory for initial starting 

and break-in, but you should have a small flat blade screwdriver handy to 

make adjustments to the carburettor during the break-in process, which will 
be detailed in the next section.

Warning!! PLEaSE rEaD THiS inforMaTion bEforE ProCEEDing!!

Your  X-Terminator  2  RTR  4WD  Nitro  Buggy  comes  equipped  with  the  user-friendly  and  powerful  XTM  Racing  24.7  nitro  engine. 

Before starting the engine for the first time, you 

MUST

 read this, and the next two sections very carefully. This section details the 

different  parts  of  the  engine's  carburettor  and  how  to  adjust  the  carburettor's  needle  valves  to  tune  the  engine. 

failure  to  read 

this  information  may  result  in  your  not  knowing  how  to  properly  operate  your  new  engine.  not  knowing  how  to  operate 
your new engine can result in damage to the engine.

  Remove the foam air filter element from the plastic bag and push it onto the air filter 

base. Secure the top of the air filter into place, using the screw provided.

iMPorTanT

 The foam air filter element comes wetted with air filter oil from the factory. 

See the information below on how to clean and re-wet the foam air filter element when 

it gets dirty.

  Slip the elbow onto the base of the air filter and secure it into place, using one nylon 

cable tie; then slip the air filter assembly over the base of the carburettor and secure it into 

place, using a second nylon cable tie.

To  clean  the  air  filter,  remove  the  air  filter 

element  and  wash  it  thoroughly  in  warm 
water and a small amount of liquid detergent. 
After  it's  clean,  allow  it  to  dry,  then  reoil  it 

and install it back onto the air filter housing. 
To wet the air filter element, simply squeeze 
an ample amount of air filter oil or after-run 
oil onto the filter element and work it through 
the  filter  element,  using  your  fingers.  Use 
enough  oil  to  completely  saturate  the  filter 
element. The endesensi filter element should be oiled, but not so much that excess oil is dripping from it.

Under no circumstances should you operate the engine without the air filter installed on the carburettor. The air filter prevents 
dust and debris from entering the engine and damaging it. If you operate your engine at any time without the air filter installed, 

the engine will not be covered under warranty should it need repair.

If you will be running your X-Terminator 2 RTR 4WD 
Nitro Buggy in dusty or wet conditions, we suggest 

using  a  prefilter  sleeve  over  the  air  filter.  Wet  the 
main  filter  element,  then  simply  slide  the  prefilter 
sleeve  over  the  main  filter.  It's  not  necessary,  nor 
desirable,  to  wet  the  prefilter  sleeve.  We  suggest 
using  XTM  Racing  1/8th  Scale  Prefilter  Sleeves 

(P/N 4942).

 We recommend placing the cleaned air filter element in a plastic bag and then applying the air filter oil on it, which allows 

you to work the oil into the element without getting excess oil on your hands.
