Thank you for choosing a Magnum XLS series aircraft engine. The XLS .52A
is a single cylinder, two-stroke engine incorporating ABC (Aluminum piston,
Chrome plated Brass sleeve) technology for long life, high power output
and easy break-in. The engine features a dual needle valve carburetor with
optional rear-mounted needle valve for precise fuel/airflow metering, dual
ball bearing-supported crankshaft, dual bushing-supported connecting rod,
and a high-flow quiet muffler. Your Magnum XLS 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 XLS series model aircraft 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 XLS series model
aircraft 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.
l
Keep spectators, especially small children, at least 20 feet away from the
engine while it is running.
l
Mount the engine securely in the aircraft or on a suitable engine test stand
to run the engine. Follow the mounting instructions in your aircraft's
instruction manual or on the plans for individual mounting recommendations.
Do not clamp the engine in a vise to test-run it.
l
Use the recommended size propeller and follow the proper procedure for
mounting the propeller. Use the correct size wrench to tighten the propeller
nut. Do not use pliers.
l
Inspect the spinner, propeller, and propeller nut on a regular basis, looking
for any signs of nicks, cracks or loosening.
l
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.
l
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.
l
If you need to carry your model while the engine is running, be conscious
of the spinning propeller. Keep the aircraft pointed away from you and others
at all times.
l
Do not use a tight-fitting cowl over the engine. It can restrict air from flowing
over the engine, which could result in engine damage from overheating.
For proper cooling, the total cowl air-exit area should be 30% greater
than the total air-intake area.
