10.2a. Adjusting maximum speed
( model
RS100)
1 - Check the rotation speed on the speed
indicator (5).
2 - Bend the plate (6) slightly upwards using pliers
to increase the engine RPM and downwards to
decrease it.
NOTE: The engine’s maximum speed must be
between 2800 (±100) rpm; if you do not read
this value, proceed as follows.
3 - Check:
- that the spring (7) is intact and that it is properly
positioned in its seat;
- that the wire (8) and the relative spring (9) are
intact and not deformed;
4 - If the above checks do not show any faults,
the phasing of the governor’s control lever (10)
with respect to the counterweight device must be
checked:
- stop the engine and make sure that the lever (10)
is in the end run position;
- slacken off the control lever (11) locknut (10);
- without changing the lever (10) position determi-
ned by the spring (9) and tie-engine shaft (8), use
a screwdriver to turn pin (12) clockwise to the end
of its stroke and then lock the nut (11).
