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 rmp. 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
full-tightening the screws on the SIMONINI 250. Now the engine SIMONINI 250 will be
ready for use for which it was designed by continuing to use a percentage of oil by 2%.
WARNING! DURING THE RUNNING-IN PHASE, KEEP PARTICULAR ATTENTION TO THE EXHAUST GAS
TEMPERATURE AND HEAD TEMPERATURE UNDER CONTINUOUS OBSERVATION.
MAINTENANCE
Each time you use the engine, remember to perform routine checks pre-start-up:
• Check the silent block condition in complete integrity
• Make sure the exhaust does not present any cracks
• Ensure that the propeller does not present cracks or dents
• Make sure you have enough fuel, according to the duration of intended use of the
engine.
• Check that the electrical system and cables do not show abrasions or disruption.
• Check that there are no screws or parts loosened.
BELT TENSION
WARNING: CARRY OUT THE OPERATIONS WITH THE ENGINE SWITCHED OFF AND COOLED DOWN
During operation, the belt is under strain and wear and as result, lengthening occurs,
which could lead to sliding on the pulleys, with a subsequent decrease in the general
engine performance.
To restore the proper tension, loosen the screw M8 (No. 39) on the foot of the engine
which fastens the pulley can, turn screw M12 (n°32) anti-clock wise using force of 1.8
Kgm and then re-tighten screw M8 (n°39)
n°39).
