1. Replacement/Adjustment Procedure for Stainless Sheet
[3] Move the slider and check the tension of the stainless sheet over the entire stroke.
If the requirement in key point of check – 1 or 2 or both requirements cannot be met, loosen the
screws again and readjust the position and tension of the stainless sheet by repeating the steps from
[1].
Caution: If the requirement in key point of check – 2 cannot be achieved even after readjustment, try
installing the stainless sheet front side back or upside down to see if the sheet can be
adjusted properly. If the problem still persists, replace the stainless sheet.
[4] After confirming the specified interval and absence of contact with the slider, alternately tighten
the two screws you have kept loose and then finally tighten all screws to an equal torque to affix
the stainless sheet. If the two screws are tightened unevenly, the sheet may wave or lift.
[5] Remove the clearance checking jig and install the original slider cover and motor cover.
Caution: Again, pay attention not to lose the coil springs.
Key point of check – 1
Check if the specified interval is ensured between the top face of the stainless
sheet and top face of the slider over the entire stroke.
Key point of check – 2:
Confirm that the edges on the stainless sheet do not contact
the slider at the positions of outer openings.
Perform this check over the entire stroke and confirm that
contact does not occur at least for the first three
back-and-forth movements.
The sheet may shift during back-and-forth movements, but if
the amount of shift does not increase and the slider makes
contact, adjust again by repeating the steps from [1].
Also note that the stainless sheet is not perfectly straight and
is somewhat waving, which makes it impossible to achieve a
uniform interval on the left and right. However, there shouldn’t
be any problem as long as the edges on the stainless sheet do
not contact the slider over the entire stroke.
Keep the clearance here even with
the one on the opposite side.
Firmly tighten the screws on both sides to prevent the stainless sheet from moving.
Tightening torque: 204 N-cm (20.8 kgf-cm)
