Loosen these nuts.
Before moving to the next step, test your bottom carriage by moving it from left to right along the track.
If travel is not smooth
, check your wheel alignment on the track. Do this be getting eye-level with the table of your
frame. The black plastic track should be centered in the v-groove of the wheel. If it is not centered, there may be
more friction than there should be in the carriage travel.
To correct this, a simple wheel adjustment can be made by doing the following:
• Loosen the nuts on the outside of the carriage, as labeled in the picture.
• On the inside of the carriage, turn the screw using a Phillips head screw driver. If the track is off-centered toward
the outside of the carriage, adjust the screw so that the wheel moves closer to the edge of the carriage. If the track
is off-centered toward the inside of the carriage, adjust the screw so it is further from the edge of the carriage.
• Repeat the above step for both wheels on that end, so they are in-line with one another.
• Retighten the nuts while holding the head of the bolt with the screw driver.
• Now retest the bottom carriage on the track.
