Fig. 92
Turn the balance wheel by hand and count, one by one, the
number of impulses made by the cam axle. Stop the machine
when the cam axle has made a full turn of 360 degrees (when
the mark on the gauge cam No. 10.2 is again in line with the mark
on the mounting plate for the “Automatic ").
Instead of turning the balance wheel by hand, the machine may
also be run with the aid of the motor. In this case, however, one
hand should be placed on the balance wheel to slow down the
machine in order to distinguish and to count the number of
impulses.
