RUNNING-IN
WARNING
• Before starting the engine, make sure that there are no loosened screws or
improperly attached parts;
• Ensure that any persons are at a distance of absolute safety and never in range of
the propeller;
•Do not start the engine where there are rocks or other objects that the force
generated by the propeller can lift and throw even at a considerable distance;
• Do not start the engine without propeller and without exhaust;
• Do not start the engine indoors: the exhaust gases contain poisonous carbon
monoxide which is toxic and can cause loss of consciousness and death.
The engine, before being sold, was subjected to a pre-running-in to verify the proper
operation and a test that confirms all the features advertised.
Once you require a MINI 3, you should pay particular attention to the first hour of
operation, in order to ensure all the engine’s qualities over time.
DURING THE RUNNING-IN PHASE, KEEP PARTICULAR ATTENTION TO THE EXHAUST GAS
TEMPERATURE AND HEAD TEMPERATURE UNDER CONTINUOUS OBSERVATION.
After having selected a suitable place and above all free from gravel or other
materials that may damage the moving parts, start the engine and let it warm up for
10 minutes at 2500 rpm, then slowly bring the engine to an higher system ,
decreasing and increasing the speed at intervals of 1 minute, thus going to affect
various "range" of use, but without exceeding the 4500 rpm. Absolutely avoid the
constant and repeated closing/opening the gas valve. After about 20 minutes from
start-up, shut down the engine and let cool completely.
WARNING! When the engine is running and even after its shutdown, it can cause
burns: so make sure it is completely cooled before working on it.
Proceed with a thorough visual inspection of any anomalies or loose parts. Once you
make sure everything is working properly and there are no problems of any kind,
you must repeat the previous operation for another 20 minutes of running,
respecting the same indications.
Last running-in phase: warm up the engine again for 10 minutes at 2500 rpm and
then, as in the two previous operations, gradually increasing the RPM. Now you can
wander over the entire range of use of the engine, bringing it several times to the
maximum speed at intervals of 1 minute.
After 20 minutes you can turn off the engine and, once cooled, you will proceed to a
