XLi EDGE Pinspotter
Section 4-2 4.2-10 Rev. Date: 10/2016
c. When pins are being set too far left or right, loosen
all four cup nuts and slide the cup on the shaft
accordingly. Tighten the nuts.
3. Clear the pin deck and set several racks to be sure pins are on spot.
4.2.2.8 Spotting Cup Toe-in
1. Run the Table down so that the pins are just touching the pin deck but are still snug in the
Spotting Cups.
2. Look under the Table and note the gap between the heels (back) of all the pins and the pin
deck. This gap should be roughly 1/8”.
3. If the gap is too large (greater than 3/16”), the Table must be moved rearward and Sections
4.2.2.5 through 4.2.2.7 must be repeated.
4. If the gap is too small (less than 1/16”) or there is no gap at all, the Table must be moved
forward and sections 4.2.2.5 through 4.2.2.7 must be repeated.
4.2.2.9 Final Spot Checks
1. Run through a dozen or more Spot cycles.
2. Check that Table motion is smooth with fluid cup rotation and no bounce. Loose Torsion
Springs on the Yoke Assembly can cause jerky cup rotation. If the Table has a bounce on its way
down to the pin deck, or if the pins seem to hit the pin deck somewhat hard, be sure the
Torsion Springs are adjusted so that the spring retaining clips are even with the top of the cup’s
u-bolt nuts. If the Table still has a bounce, try wiping some lane oil on the Spotting Cup Liners
and see if the problem goes away. The last thing to check would be the 3/16” gap under the
head of the Table Leg Screw. Readjust if necessary.
3. Be sure that pins do not wobble or fall over when spotting. If pins wobble or fall over:
a. check that there are no broken or chipped bottom rings on the pins, and that there is no
debris on the pin deck.
b. Next, check the Table height adjustment (5/16”) and toe adjustment.
c. If the height and toe measurements are correct, check the Spot Rod adjustment.
d. If the Spot Rod adjustment is correct, remove one of the smaller counterbalance springs from
the Torque Tube. If pins spot well now, the Table will have to run for some time without this
spring, until the pivot points wear in some and loosen up.
