nuts on this roller bearing (Fig 8c). After tightening the side roller, the spacer block should be snug with
resistance when removing it but not so tight as it is difficult to remove. With both ½” spacers
still in place, and
the sled still locked, follow the same procedure for the other SIDE ROLLER bearing on the other side of the sled
(Fig 8b & Fig 8c). Both spacers should now provide resistance when removing them but not so tight as to be
difficult to remove.
Now you have adjusted the operator side, sled guide rail and the 2 sled side bearings that run against the
operator side, sled guide rail. (
Be sure the Bolts on the other sled guide rail are loose
). Roll the sled back and
forth to be sure it moves freely. (Do not worry about the “play” in the sled at this point
). The (2) roller bearings
on the other side of the sled will take care of the play. Run the sled back and forth from one end of the
machine to the other a few times. The white bearing blocks inside the sled will help adjust the other sled guide
rail.
Step 3)
If you are satisfied the sled is moving freely, move on to adjusting the other sled guide rail. The
measurement between the inside
of the “operator side” sled
guide rail to the inside of the other sled guide rail
should be between 13 -
1/16” to 13
-
3/16”
(Fig 8d). There can be some variance between machines but the
important point is to be sure the measurement between the sled guide rails is the same on both ends of the
machine. If you measure 13 -
1/16”
on the inside of the guide rails on one end of the machine then the
measurement between the inside sled guide rails should be exactly 13 -
1/16” on the other end of the
machine. (
NOTE
: the corners of the sled guide rails are rounded so it is best to use a flat edge such as a steel
ruler to measure to).
With both measurements exactly the same, tighten the sled guide rail bolts on both ends
of the sled guide rail making sure the guide rail does not move while you tighten the nuts and bolts. Re-Check
your measurement after the bolts are tight. Move the sled all the way back and forth a few times to ensure
the sled is moving freely.
(NOTE: There will still be play in the sled as you move it back and forth at this point.
The next step will take care of this).
If the sled is difficult to move at one end but free on the other end then the distance between the guide rails
is not equal. Re-Check your measurement. (
NOTE: There may be slight resistance in some points while moving
the sled back and forth. This is due to the powder coating on the guide rails. The inner bearing blocks will polish
the rails as you move it back and forth over time and the resistance will even out).
To keep the guide rails clean
and polished, use a spray furniture polish or floor wax.
