5. To perform a coarse track width adjustment, use a 3/32-inch hex

wrench to loosen the four set screws in the cable pinch block (see

Figure 5-29). Use calipers or a device to set a constant width for all

three track sections. Use a needle-nose pliers to pull one of the cables

away from the adjustment nuts to make the track wider, or push the

cable toward the adjustment nuts to make the track narrower.

6. Tighten the four set screws to lock the cable(s) in their new position.

Recheck the track width by opening the track to its widest setting

and then closing it down to the width used in step 5.

7. Apply a drop of silicone-based glue (such as RTV™) where the cable

enters the cable pinch block.
