X Contact Check
When winding from the maximum
curtain travel position (MCTP), the
contact separation is 0.3mm when
the brake claw is on the third ratchet
tooth.
Also, when winding from the MCTP,
the contact drive dowel must have at
least 0.5mm total travel.
SW 18 Check and Adjustment
While winding slowly from the MCTP,
adjust so that SW 18 turns on when
the brake claw has traveled 2 to 2.5
teeth. Adjust by bending the fixed
contact.
(Visual Check)
With the brake claw at the third
tooth, check that there is at least
0.2mm separation between the drive
pin and the switch lever.
Apply TUFFY TF-1156 to the marked
areas in figure 1.
