INTRODUCTION
Congratulations on purchasing a Zenoah engine. Cared for
properly, these high-quality, finely crafted engines will offer
many years of reliability.
This instruction manual has been developed to ensure opti-
mum performance from the Zenoah engine you have pur-
chased. It’s important that the instructions are read
thoroughly prior to mounting and running the engine.
SAFETY INSTRUCTIONS
This manual describes the engine’s features and functions.
For specific information on mounting, see the instruction
manual included with the model airplane, helicopter, or boat
in which you intend to install the engine.
This model engine will give you considerable pleasure, satis-
faction and performance if you strictly follow these safety
instructions and take heed of the warnings as to the engine’s
safe and proper use. Remember at all times, this engine has
more than enough power to cause harm if misused or if the
safety precautions are not observed.
YOU SHOULD ALWAYS:
1. Use genuine parts for replacement.
2. Check the propeller, rotor (helicopter) or screw propeller
(boat) prior to each time the engine is used. If nicked,
scratched, cracked, or damaged in any way, replace it
with a new one.
3. Use the correct size and pitch of propeller for your
engine; refer to the propeller chart in this manual.
4. It is extremely important to balance the propeller prior to
installation of the engine. Failure to do so may cause
damage to the Zenoah engine and/or the airframe.
Securely tighten the propeller nut against the washer
and propeller.
5. Inspect the tightness of the propeller nut prior to each flight.
6. Keep your face and body away from the path of the pro-
peller blades when starting or running your engine.
7. Use a thickly padded glove when hand starting the
engine.
8. Make all carburetor adjustments from behind the propeller.
9.To stop the engine, the black lead wire from the coil
should be grounded to the engine body, or use the
throttle linkage to shut off the air by closing the throttle
valve completely.
DO NOT USE HANDS, FINGERS OR ANY OTHER
PART OF THE BODY TO STOP THE PROPELLER. DO
NOT THROW ANY OBJECT INTO A PROPELLER TO
STOP IT!
10. Ensure that all spectators, especially children, are at
least 20 feet away when you start running the engine.
11. Make sure your fuel is kept in a safe place well away
from sparks, heat or anything that could ignite the fuel.
IT IS HIGHLY RECOMMENDED THAT:
1. Safety glasses or goggles be used when starting and
running your engine.
2.You do not run the engine in the vicinity of loose gravel
or sand.The propeller may throw such materials into
your eyes.The engine could also ingest these harmful
materials.
3. Loose clothing should be avoided when operating your
model engine, as it could become entangled in the pro-
peller, creating the possibility of bodily harm. Also, all
loose objects (screwdrivers, pencils, nickel cadmium
glow drivers, etc.) should be removed from your pockets
so that they do not fall into the propeller.
CAUTION:
1. Model engines get very hot while running. Do not
attempt to handle them until they have cooled.
2. Always run your model engines in a well-ventilated
area. Similar to automotive engines, model engines pro-
duce harmful carbon monoxide fumes.
3. Never modify the flywheel.
4. Check the flywheel. If it’s damaged, replace it with a
new one.
5. When mixing the fuel or operating the engine, do so in a
well-ventilated area
6. Remember that model engines produce a substantial
amount of power, more than enough to seriously injure
people and/or do considerable damage to property.
Always use common sense, skill and constant observa-
tion of safety precautions.
