PICK-UP SPRING PRE-LOAD ADJUSTMENT
For correct operation the pick-up must be pre-loaded with a spring. To do so, the spring must be compressed by a screw, according
to the following:
1. ALL PROCEDURES (INCLUDING MINOR) MUST BE CARRIED OUT BY QUALIFIED STAFF;
2.
BEFORE PERFORMING ANY PROCEDURE, DISCONNECT THE ELECTRICAL POWER SUPPLY
;
3. Tighten the hex screw, by hand, as far as it will go;
4. Repeat step 1 for the other pick-up;
5. Make sure that the springs and hex keys are perpendicular to the pick-up support unit. If necessary, loosen the screw, turn
the spring (or switch it around the other way) and repeat steps 1 and 2 until the set-up is perpendicular;
6. Tighten the screws on the two pick-ups by turning them three full times. It is good practice to spin the two pick-up springs
by a full turn, alternating one at a time. See picture F2.1;
7. Calibrate the machine.
IMPORTANT: Every time a pick-up tightens or loosens, it is compulsory to calibrate the machine.
