Check the collet hub adjustment (see section A above (p. 2.3), step2). The collet hub must be correctly adjusted before you adjustthe door.3. Loosen the two mounting screws (Fig. 3, #2) and center the door inits opening.4. Check the door for evenness with the front of the bezel. Adjustthe door if necessary; then tighten the door mounting screws.5. Insert the Adjustment Tool into the drive and allow it to centerproperly.6. While gently closing the drive door, observe the two guide bars(Figure 3, #1), which are visible when viewed from the back of thedrive looking towards the front. There should be no bindingbetween the guides and the tool.7.
