1. Turn the adjusting bolt of special tool MB991561 to adjust 

the opening dimension (W) to the standard value.

NOTE: The dimension (W) is adjusted by approximately 0.7 
mm (0.03 inch) per one turn.

NOTE: Do not turn the adjusting bolt more than one turn.

Standard value (W): 1.9 mm (0.07 inch)
<When more than 1.9 mm (0.07 inch)>: Screw in the 
adjusting bolt.
<When less than 1.9 mm (0.07 inch)>: Loosen the 
adjusting bolt.

(0.07 inch), (W) is 3.6 mm (0.14 inch).]
<When less than 1.4 mm (0.06 inch)>: Remove the 
bellows band, readjust the dimension (W) of step (1) to 
the value calculated by the following equation, and 
use a new bellows band to repeat steps (2) to (3).
W = 5.5 mm (0.22 inch)
