PRO-18BX / 9442 SHOWN
INTRODUCTION
Congratulations on your purchase of a Thunder Tiger model engine. The
latest Thunder Tiger PRO-12/ 15/ 18 series car engines have been designed
for one tenth scale radio-controlled model cars to combine high performance
with easy handing and maintenanc e using modern CAD compu ter
technology. Majo r components of the engines are mac hined from the
highest quality materials using state-o f-the art CNC manufacturing
techniques, resulting in consistently high performance and reliability. The
PRO series engines are equipped with dual-ball bearings, Schnuerle
porting, ABC type piston and cylinder, and automatic mixture control
carburetors.
IMPORTANT
Be certain to completely read all of the instructions su pplied with your
engine, and pay close attention to the "SAFETY INSTRUCTIONS AND
WARNINGS".
SPECIAL ATTENTION
When you rotate the crankshaft of your engine by hand, you may find that
it becomes rough or "notch" as the piston approaches TDC (Top Dead
Center). This is not a defect or manufacturing fault, indeed it is normal
for an engine of ABC type construction. When the engine runs, the cylinder
actually expands as it heats. The cylinder has been precision machined
so that (at optimum operating temperature) the cylinder walls are perfectly
aligned with the piston. A s the engine cools after a run, you will notice
that the tightness will actually return. This is normal and typical of an ABC
type engine.
LEARNING ABOUT YOUR ENGINE
Before actually operate your engine, the following information is for the
benefit of the newcomers with no previous experience of model engines.
Please put the engine near you and read this instruction. The model engine
is just like the engine of a motorcycle or a car that needs a key to start.
You have to prepare some accessories and knowledge. It is not hard to
operate your model engine by following the instructions properly.
RECOIL STARTING SYSTEM & SHAFT STARTING SYSTEM
The Thunder Tiger "X" type series engines feature a built-in recoil starting
system that eliminates the need for a separate electric starter and battery
or a starter box, and allows the engine to be started easily by simply
pulling the starter handle.
1) Pull the handle straight away from the starter housing so that it prevents
the cord from being damaged by rubbing against the starting wheel
cover or car body.
2) Let the cord recoil slowly while still holding the handle. Do not release
the handle abruptly.
3) It is recommended to keep the cord away from fuel, as fuel will weaken
the cord and cause it to break.
4) The recoil starter system is developed to operate in a counter clockwise
direction (when viewed from front of the engine). If you attempt to crank
the flywheel or force the engine in the opposite direction, the one-way
clutch set will be damaged.
5) The spring in the recoil system is under extreme tension! If it is necessary
to dismantle your engine, remove the starting wheel cover set gently
to prevent damage or injury.
The Thunder Tiger "K" type series engines feature a built-in hexagonal
shaft starting system that can be operated to start the engine as simple
as the "X" type series. Please refer to the instruction of your model
vehicle for the compatibility of installing the "K" type series engine on
your model vehicle.
1) To use the Hex Starting shaft, either a cordless drill or 12V DC handy
starter is required.
2) Install the extended 6mm hex starting tool into the cordless drill or a
12V DC starter.
3) BEFORE inserting the Hex Starting shaft into the back start output,
squeeze the trigger and verify that the drill is turning the same direction
as is shown on the sticker on the back start cover.
4) Attempting to start the motor by using a counter-clockwise direction
could damage the pull-start mechanism or possibly the engine internal
components. Insert the ball end of the Hex Start shaft into the Dual
Start output. Grasp the drill tightly and squeeze the trigger.
NECESSARY ACCESSORIES
The following items are necessary for operating the engine, these are
available at you hobby dealer.
FUEL
A good quality, commercially available fuel containing 25% lubricant and
75% methanol is recommended for break-in/run-in and general usage.
We also recommend castor oil or a castor/synthetic blend only for use
as a lubricant. Fuel containing 10%-30% nitromethane and 20% lubricant
is for use when more power is required. Most fuels containing synthetic
lubricants (only) are much less tolerant of a lean run compared to fuel
that contains castor oil. If availability or local conditions force you to use
a fuel that contains only synthetic lubricant, we suggest that you keep
your needle valve set to a slightly richer setting, allowing more lubricant
to flow through your engine to extend engine life and maintain optimum
reliability. Do not use fuel containing less than 20% lubricant.
CAUTION 1
Methanol and nitromethane are poisonous and highly flammable.
Keep out the reach of small children and keep away from heat
and open flame.
CAUTION 2
Excessive heat can great reduce the life of your engine. Most
of the heat generated by combustion is removed via the
lubricants that are contained in your fuel, and exits the engine
as exhaust vapor. As a precaution, you should periodically
remove the muffler from your engine and visually inspect the
exhaust port and piston. If the outer surface of the piston is
stained a very dark color, it can indicate that your engine may
be overheating. This can be caused by either an excessively
lean needle setting or a lack of airstream across the cylinder
and head.
