4. Identify the defected one and proceed to replace-
ment;
5. With a screw driver unscrew the two wires on the
micro, remembering the position and memorizing
the type of contact on which they are fitted (nor-
mally NO);
6.
With a hex key unscrew the micro switch from its
support, remove it and install the new one;
7. Mount the new micro connecting the wires on the
contact that is normally open (indicated as NO or
NA) and screw the two nuts that can be found on
the metal body of the micro, being careful to adjust-

lic click) and at the same time must remain a little
bit of extra throw in case there is a strong and deep
pressure by the operator;
8. Once everything has been checked tighten the two
locking nuts of the micro body and close again the
bottom of the pedal box with the four screws in
reversed order to what previously done to open the
pedal box.
