2 By exerting a pressure of at least 5 Kg., check
that the belt does not flex by more than 5 mm.
compared to its original position (Fig. 120-121).
If this distance should exceed 5 mm., intervene
by loosening the motor fastening screws
(Fig. 122-123), remove the driving belt and move
the motor away from the compressor by a few
millimetres by sliding it along the slots.
Tighten the motor fastening screws.
Refit the belt, placing it in the race provided in
the motor pulley and in the innermost race of the
fan, turning it by hand to enable the belt to go
over the diameter of the fan and to fit into the
race.
3 Carry out the measurement procedure again
and if necessary, repeat the operations until a
maximum distance of 5 mm. is reached.
4 Replace the covers securing the appropriate
screws tightly (see point 1).
