To switch the mode, rotate wheel gear 2 while the motor bracket assembly is disengaged (see 2.2, “Mechanism Modes”). 2)Rotate the tension arm slightly clockwise to elimi- nate production of rattle with the band arm plate. 3)Ensure that the notch on the tension arm is located within

28、area A. (See Fig. 2-7-8(e).) 4)If the tension arm is not located in area A, loosen screw B (black) lightly and fine-adjust the position of the band arm plate assembly. Turn the screw counterclockwise to move the tension arm extrem- ity toward the right or clockwise to move it toward the left. 5)Afte

29、r the adjustment, clamp the band holder by tightening screw B (black) (with a securing torque of 5.88 Nm, or 0.6 kgf-cm). Then adjust the ten- sion arm position again.
