Thank you for choosing a Magnum XL RFS series aircraft engine. The XL
1.80RFS is a single cylinder, four-stroke engine incorporating an aluminum
piston, iron ring and steel sleeve for long life and high power output. A
dual-needle valve carburetor for precise fuel/airflow metering is standard.
The engine features a dual-ball bearing-supported crankshaft and camshaft,
dual bushing-supported connecting rod, and a high-flow muffler for more
power and reduced noise. Your Magnum XL RFS series engine was designed
by expert engineers and built by master craftsmen using only the highest
quality materials and CNC machinery. These qualities provide the long life
and dependability you have come to expect from an engine of this caliber.
Magnum XL RFS series model airplane engines will consistently give you
dependable performance and reliability and will be a source of satisfaction
and pleasure if you follow these instructions as to the engine’s proper and
safe use. You alone are responsible for the safe operation of your engine,
so act sensibly and with care at all times. This Magnum XL RFS series
model airplane engine is not a toy. It is a precision-built machine whose
power is capable of causing serious injury to yourself and others if abused or
misused, or if you fail to observe proper safety precautions while using it.
●
Keep spectators, especially small children, at least 20 feet away from the
engine while it is running.
●
Mount the engine securely in the airplane or on a suitable engine test
stand to run the engine. Follow the mounting instructions in your kit's
instruction manual or on the plans for individual mounting recommendations.
Do not clamp the engine in a vise to test-run it.
●
Use the recommended size propeller and follow the proper procedure for
mounting the propeller. Use the correct size wrench to tighten the propeller
nut and the safety nut. Do not use pliers.
●
Inspect the spinner, propeller, and propeller and safety nuts on a regular
basis, looking for any signs of nicks, cracks or loosening.
●
To stop the engine, adjust the throttle linkage to completely close the throttle
barrel and therefore cut off the fuel/air supply. You can also pinch the fuel
line to stop the engine, but only if it is accessible. Do not throw anything into
the spinning propeller or attempt to use your hands to stop the engine.
●
While the engine is running, stand behind the engine to make any
adjustments to the needle valves. Do not reach over or around the propeller.
Do not lean toward the engine. Do not wear loose clothing or allow anything
to be drawn into the spinning propeller while the engine is running.
●
If you need to carry your model while the engine is running, be conscious
of the spinning propeller. Keep the airplane pointed away from you and
others at all times.
●
Do not use tight-fitting cowls over the engine. They can restrict air from
flowing over the engine, which could result in engine damage from overheating.
