If the values displayed after the spin cycle are not within the specified ranges, use the stud
bolts to tighten down the pickups until the readings are correct.
The correct values are usually obtained at a tightening torque of 2 Nm.
-
Fully tighten down the locknuts and then release them slightly (about one sixth of a turn)
to load the Belleville washers.
During this operation, immobilize the stud bolts so as to avoid altering the pickup
preloads.
-
Refit the side casing and the weight-holder lid.
-
Run a three spin cycle sensitivity calibration.
REPLACING THE BRAKE PEDAL SWITCH
-
Remove the side panel;
-
unscrew the ring nuts securing the switch to its mount;
-
disconnect the cable from the switch's terminal block;
-
connect the cable to the new switch;
-
fit the new switch to the mount (the position is unequivocal since no adjustment is required);
-
tighten down the two ring nuts (nut and locknut).
REPLACING THE ENTIRE CENTRAL UNIT
After making sure that the unit is really the cause of the machine's malfunctions, replace it as
described below:
-
Remove the weight-holder lid.
-
Remove the search circuit board complete with mount by undoing the two M8 screws
securing it.
-
Remove the central unit by undoing the two M12 bolts with a 19 wrench.
-
Fit the new central unit, locating it to ensure perfect coupling between the spin unit base
(front reference plane) and the block to which the leaf springs are mounted. Also make
sure that the drive roller is centered on the pulley.
-
Fit the search circuit board with its two M8 bolts, making sure that the encoder disk teeth
can run inside the fork without collisions.
-
Reconnect the pickup cable and the search circuit board.
-
Close the weight-holder lid again.
-
Run a three spin cycle sensitivity calibration.
REPLACING THE QUICK LOCK CENTRAL UNIT PNEUMATIC CYLINDER
GASKETS
The cylinder gaskets
must be replaced
whenever there are air
leaks or piston operation
is defective.
•
Remove the weight-
holder lid;
•
Undo the two bolts
securing the rear
flange of the
pneumatic cylinder;
•
Recover the inside
spring (B);
