● The throttle and choke pushrods should be non-metallic.

●

In case 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 passages inside the

carburetor. Because the carburetor is more complicated than those

used in glow engines, keep the fuel clean by using a fuel ﬁ lter. Use a

ﬁ lter intended to be used with gasoline engines. Metal ﬁ lters intended

for glow engines are too coarse and will not screen out ﬁ ner particles.

● Always ﬁ lter your fuel by using an appropriate ﬁ lter before putting

it into the airplane’s fuel tank.

● Gasoline is extremely ﬂ ammable. Keep it away from an open ﬂ ame,

excessive heat or sources of sparks.

● Do not smoke near the engine or the fuel tank.

● This engine was designed for use in a model aircraft. Do not

attempt to use it for any other purpose.

● Always install an ignition system on/off switch on the aircraft used.

● Caution: Running the engine with a lean gas mixture will cause

the engine to overheat and burn the electrode of the spark plug.

Pay close attention to the High-Speed Needle adjustment. Running

the engine with the proper gas mixture will make the spark plugs

appear yellow at the ignition point.

● For optimum performance please use fresh or recently purchased

87– 93 octane gasoline with a 30:1 gas /oil 2-stroke (2-cycle) mixture.

● Excessive running of the engine at idle speed can result in a

seriously carbonized spark plug.

●

Keep the surface of the engine clean to ensure proper heat dissipation.

● To avoid permanent damage to the electronic ignition system,

NEVER rotate the propeller on your DLE engine with the

electronic ignition system switched on and the plug not installed

in the plug cap.

●

If you choose to use the optional TX activated gas engine kill switch

(DLEG9205) it is strongly recommended that you install the TX

activated kill switch between the with a manual on/off switch and

the ignition. The manual on/off switch provides an added safety

feature in the event the TX activated kill switch does not function

properly. This is especially important during the starting sequence

as it requires the manual on/off switch to be in the ON position

before ignition can occur.
