WARNING!
Magnum model engines will consistently give you dependable perfor-
mance 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 sensi-
bly and with care at all times. This Magnum model 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, misused or if you fail to observe
proper safety precautions while using it.
N
Keep spectators, especially small children, at least 20 feet away from
the engine while it is running.
N
Mount the engine securely in the airplane or on a suitable engine test
stand to run the engine. Follow the mounting instructions in your kits
instruction manual or on the plans for individual mounting recommenda-
tions. Do not clamp the engine in a vise to test run it.
N
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.
N
Inspect the spinner, propeller and propeller nut on a regular basis,
looking for any signs of nicks, cracks or loosening.
N
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.
N
While the engine is running stand behind the engine to make any ad-
justments to the needle valves. Do not reach over or around the propeller.
Do not lean towards the engine. Do not wear loose clothing or allow any-
thing to be drawn into the spinning propeller while the engine is running.
N
If you need to carry your model while the engine is running, be con-
scious of the spinning propeller. Keep the airplane pointed away from you
and others at all times.
N
Do not use tight fitting cowls over the engine. They can restrict air
from flowing over the engine and result in engine damage from overheating.
ENGINE INSTALLATION
q
Engine Orientation
The Magnum XL .30RFS engine can be orientated in any position on the
firewall. Keep in mind that if you mount the engine inverted, carburetor
adjustments will need to made differently and the fuel tank may need to be
lowered. (See fuel tank size and orientation to carburetor on next page).
Engines mounted inverted tend to run richer during idle and transition to
full throttle, and are generally more difficult to setup and tune properly.
