7. Check the clearance between the pulley (4) and the anchor disk (3) over the entire circumference. Nominal value: 0.35-0.65 mm. If the measured value is greater than the nominal value, remove the anchor disk and install or remove the adjusting washer to increase or decrease the clearance, respectively.
Note: 0.7mm thick adjusting washers are supplied as spare parts; 0,8; 0,9; 1,0; 1,1; 1.2 and 1.3 mm.
