The screw tightening pattern is the most important process in making this adjustment. The
pattern illustrated in figure 11 will bring the table down evenly so it sits as flat as possible. The
process is as follows:
1. Tighten all screws by number only using two fingers on the hex key. Do not crank them
down real tight, it should be a soft snug. Figure 12 shows the pattern.
2. Make a second tightening pass to snug the screws down tight. Exclude the lead nut
screws from final tightening (screws 1-4). They will be done in the following steps.
3. Once screws 5-20 are tight jog the table left and right a few times in the X direction. This
will help to seat everything before the lead nut is tightened. Once done make final
tightening of the lead nut screws in order.
4. Do a final check on the table pitch and roll to make sure you have done it correctly.
