3: Raise the backplane to install badly.

Eliminate the method:

(1) Raise the position of the backplane to lift or fall in place. High and low position in the shuttle low board spacing to 9mm is appropriate.

(2) raised the back plate in the foot, the shuttle wire surface should be lower than the bottom of the shuttle box 1.6mm, before and after the distance should be less than half of the shuttle. Correction should be noted that the shuttle wire should not be loose.

(3) control the wood in the front and rear rail position before and after, should be corrected for the width of the two shuttle (one is one) plus 0.8mm. High and low position should be higher than the bottom of the shuttle box 13mm.
