Squaring The Backgauge - Challenge CHAMPION 305 Instructions And Parts Manual

To adjust:
1. Send the backgauge back to approximately 28" (711mm) and disconnect the power.
2. Always adjust the side gib first. Loosen all jam nuts and adjusting screws then tighten the
front and rear screws.
3. Pull each end of the backgauge and try to rock it side to side as before to check for play.
4. Continue to adjust these two screws until there is no play and the hand-wheel still turns easily
5. Lock the screws in place with the jam nuts.
6. Snug up the middle two screws and lock in place with the jam nuts.
7. Snug up the bottom gib adjusting screws finger tight, then back it off 1/8 of a turn and lock in
place with the jam nuts.
8. Run the backgauge back and forth to make sure it does not bind. Readjust if necessary.

10. Check the backgauge squareness.

12.3 Squaring the Backgauge

To test the backgauge for squareness, place a small lift of paper against the left side of the
backgauge (but not against the side guide) and make a cut.
Now, leave the backgauge in the same position, flip the lift over and against the right side of the
backgauge (but not against the side guide). Make another cut to see if any of the stock will trim off.
Run two checks, one starting on the left and moving to the right, the other, moving from the right to
the left. Trim in either sequence indicates the backgauge is out of square.
