Welcome to purchase your SMARTECH RC engine powered model car. Please
read this instruction carefully before you starting any work.

Driving a radio controlled car is a fascinating hobby which has to be practiced
with the necessary caution and respect. A radio controlled model car which
has a considerable weight and can reach a very high speed can cause damage
and injuries in cause of uncontrolled driving conditions and the user is liable
for this.
Only faultless assembled model will operate and react in the expected
manner. Never improvise with any not suitable aids but use only the original
spare parts if necessary. Even with a prefabricated model you have to control
all connections and check whether they are screwed tightly.
The servo must be set at the center position before installation.To set at a
neutral position, turn on the transmitter and receiver. Set the trim levers in
the center position and turn off the receiver, and then the transmitter.The
servo will be proper neutral position for installation.
Never start driving before you have made sure the followings:
Batteries for transmitter and receiver have a good potential and not weak.
All operable parts are in good condition and you have tested their
operation.
You have made sure that all screws are tightened.
There is no other RC or similar transmitter nearby which could cause
interference.
The terrain where you want to drive isn’t used for common traffic and is
not claimed by any persons or animals.
You transmitter and receiver is switched on and you have checked all
control operations which can be performed.
In case of any porblems concerning your car please contact your local
hobby shop!
We wish you good luck and a lot of fun driving with your SMARTECH
model car.
After each drive all important parts and connectors should be tested.One
simply loosened screw can be sufficient to be lead you model into a
dangerous situation! Attend to your car in regular periods and exchange
defective or worn parts with original spare parts.
Precaution about your engine RC car Tools needed for assembly

As a precaution we recommend to change or clean the foam inserts
more often. Before use the foam insert should be impregnated with
air filter oil spray.

1. Initial operation of the engine
2. Starting the cold engine
Close the carburetor throttle valve or set it to the idling position. Now shut
the choke flap at the carburetor. Press the primer pump at the carburetor
until it is filled with fuel. Slowly pull out the rope starter until you feel a first
resistance,then pull strongly until the engine ignites audible.Normally the
engine will stop again after this first ignition. Now open the choke flap and
pull the rope starter once again until the engine runs.To turn the engine
off, press the ignition switch until the engine stops.(See picture 1)
Always check if the air filter is mounted correctly and firmly before starting
the engine.The basic adijustment of the engine is set by the factory.The
mixture of petrol and lubricating oil should be 1:25 which means a share
of 4% 2-stroke lubricant (5L petrol/200ml lubricant). Suitable is super or
super plus petrol.
4. Carburetor adjustment
5. Basic adjustment of the carburetor
The adjustment of the carburetor is pre-set by the factory to the local
conditions. Depending on air filter, exhaust silencer and operating
conditions a correction may be necessary.
Drive the car at medium rpm until the motor has reached his operating
temperature. If the engine decelerates a little during acceleration the it
runs to lean. In this case open the idling adjusting screw L anticlockwise.
if the engine revs up only slowly stammering and with clouds of smoke
coming out of the echaust the engine probably runs with a too rich
mixture.
In that case you should close the idling adjusting screw 1
clockwise.In order to adjust maximum rpm litt the rear wheels and set
the throttle of the warm engine to the wide open position for a short
time. Now you can turn the full throttle adjusting screw. If the mixture
seems too rich turn to the left, if it seems too lean turn to the right.
The specified values serve as reference. In some cases the carburetor has
to be readjusted. If you get the feeling that no-load adjustment screw 1 or
the Full-road adjustment screw 2 is completely misadjusted then close
both screws 1+2 carefully. Afterwards open the adjusting screw clockwise
corresponding to the values below.
1 No-load mixture adjusting screw 1,25 turns.
2 Full-load mixture adjusting screw 1,5 turns.
During the first two tank fillings you should avoid maximum speed under
no-load condition as well as longer full speed drives on flat areas. First of
all we recommend to check the range of your radio control system while
the engine is running.
Never operate the engine in closed-up rooms without sufficient
ventilation. Further safely instruction are enclosed with the engine.
