SAFETY TIPS AND WARNINGS

1.

 Always use a balanced spinner and a balanced prop. An unbalanced spinner and prop combination will
cause high levels of vibration and may cause the propeller shaft to break. ·

2.

Always use a lightweight spinner on your engine. Lightweight spinners are considered to be those with
a cone wall of 1mm or less. Heavy spinners could cause the propeller shaft to break. ·

3.

Securely tighten the spinner and prop on the engine to prevent it from being thrown off the engine while
running. ·

4.

Never use a prop that has hit the ground. Even though it may look good from the outside, it may be
cracked on the inside which may cause it to disintegrate while in use. Do not use a nicked, cracked or
split propeller. ·

5.

Keep foreign objects away from the propeller. Make sure that nothing can be “sucked in” by the propeller.
Never start the engine on loose gravel or sand. ·

6.

Keep onlookers away from the running engine, especially small children. ·

7.

Do not attempt to stop the engine by throwing anything into the path of the propeller. ·

8.

Make sure the fuel line is well-secured to the engine and to the fuel tank so that it won’t come off in flight.

OPERATOR’s MANUAL FOR SPE-26CC

1.

Do not use silicone fuel line because it will be attacked by the fuel. Use vinyl or neoprene rubber fuel line.

2.

Always secure the fuel line away from the cylinder head. The engine’s heat can damage the fuel line.

3.

Never touch the engine after a run. The engine will be hot and it may burn you.

4.

Before transporting your model, remove all the fuel from the fuel tank and fuel lines.

5.

Always use high-quality oil intended for 2-stroke engines.

6.

Use only low octane, alcohol-free gasoline. The carburetor diaphragm will gradually deteriorate if you
use gasoline with alcohol (ethanol, gasohol, etc.).

7.

You will need to replace the diaphragm in about 80 hours of operation if you use gasoline with alcohol.

8.

Muffler pressure to the fuel tank is not required.

9.

Do not install your throttle servo or kill switch servo inside the engine compartment. Doing so could
cause radio interference. Install all electronic radio devices at least 305mm [12"] away from the engine.
The throttle pushrod should be non-metallic.

10. If the engine is not to be used for more than a month, drain the fuel tank and remove any fuel from inside

the carburetor. Do this by running the engine at idle until it quits by running out of fuel. Keeping gasoline
inside the carburetor over an extended period of time will damage the diaphragm valve and clog pas-
sages inside the carburetor.

11. Because the carburetor is more complicated than those used in glow engines, keep the fuel clean by

using a fuel filter. Use a filter intended to be used with gasoline engines. Metal filters intended for glow
engines are too coarse and will not screen out finer particles. Always filter your fuel by using an appro-
priate filter before putting it into the airplane’s fuel tank.

12. If you intend to run this engine on an engine stand, or on any other rigid mount, use rubber mounts. The

crankcase and other parts of the engine may crack if you do not provide some kind of vibration absorp-
tion mechanism.
