Place #1 Phillips screw driver through socket and loosen Phillips screw.
c.
Rotate bearing very slightly away from the Y rail, i.e., towards the narrow side of the
eccentric, using the socket. Snug the Phillips screw.
d.
Remove screw driver and socket and recheck per Step 7. Adjust until friction is
correct. Hold the socket still with your fingers then insert the #1 Phillips through the
socket and tighten the screw. Do not over tighten the Phillips screw.
CAUTIO:
Turn the 7mm socket with your fingers, not with a wrench. Over tightening the
eccentric bearing will cause permanent damage to the bearings.

a.
Place 7mm socket over eccentric bearing (reference Figure 9).
b.
Place #1 Phillips screw driver through socket and loosen the Phillips screw.
c.
Rotate bearing very slightly towards the Y rail, i.e., towards the wide side of the
