A. General Warnings:
1.Verify all screws and nuts are firmly secured on the engine. Verify the engine with all wirings
well-connected and a complete oil tubing.
2.Consider the engine to be securely installed to the car.
3.Provide a good air ventilation for engine against getting choked. Allow reliable clearance for
engine to cool down shortly.
4.Double check oil tubes, all wirings after being installing. Failure to do so can cause malfunction
of engine, even damage to engine.
B. Safety Information:
1.Keep away any source of heat/an open fire when re-fueling to the gas tank.
2.Verify no leaky details are found on the gas tank, the fuel tubing/tube joints.
3.Perform a proper manner to start the engine.
4.Always avert touching the muffler, the glow plug which can generate too much heat. Otherwise,
it would cause burn.
5.Recommend to wear the uniform to handle with engine. Take care not to get your clothing ( laps,
ties, hand ornaments..) entangled with the projecting parts on the engine when working.
6.Take good care of everyone else standing by when you are starting the engine.
7.Hold the car securely before running the engine.
8.Pure gas is not recommended for start of engine.
Notification:
We can not have a trail control of our products to be properly used by operators. Any malfunction
and/or damage will void our responsibilities.
C. To start the engine (We warmly recommended the engine starter
to be used.)
1.Before starting the engine, fuel the gas tank with the gas mixture properly mixed in proportion
in terms of the instructions in Page 2.
l Check if the engine is well secured on the car.
l Holding the car when starting the engine.
l Check there is no moving/juddering parts (such as the glow plug, the hood, wirings and /or
connectors) on the engine.
l Turn on the transmitter then the receiver...
2.Press the oil pump on carburetor to allow fuel flow into carburetor.
3.Close the choke valve , use the starter or pull starter to start the engine until ping sound is heard,
and then open the choke valve.
4.The engine starts...
D. Breaking-in of engine
1. Recommended to be used for breaking-in of engine:
l No.90-No.93 gasoline as the fuel l FC two-stroke gas engine oil as the lubricant
According to volumetric ratio, measure a proper proportion of mixture.
th
th
Initially, the proportion of 1/20 -1/25 of the mixture is recommended for engine to run for
th
the first eight hours. Then, measure it down to 1/30 or so.
2. For the first four hours, never allow engine speed to run more than 5000 rpm. Then, the
th
th
engine comes to normal working. (Note: the proportion of 1/20 - 1/25 of the mixture is for
th
the first 4 hours and the proportion of 1/30 is for the second four hours.)
3. Never attempt to arbitrarily adjust the carburetor needle during breaking-in. The engine will
run smoothly after breaking-in is performed.
4. Proper proportion of the mixture to be used is essential to perform a smooth breaking-in
procedure and keep engine running in a good manner for long time as well.
E. Adjustment of carburetor
Every engine is securely tested and
adjusted at factory. Normally, we do not
recommend users to re-adjust the
carburetor unless special demand.
Methods of adjustment:
-For lean oil measure, adjust the
needle clockwise.
-For rich oil measure, adjust the needle
counter-clockwise.
H: high end mixture needle
L: low end mixture needle
Cross Head Screw is the idle adjustment
needle.
Conforming to instruction adjust these needles.
Properly run the engine before adjusting high/low end mixture needles.
Adjust high/low end mixture needles in phase keeping proper inflow of mixture.
Re-adjustment is required for optimum performance.
An improper inflow of mixture will compromise engine performance and/or cause an uneven
running speed.
