7. Turn the thrust washer under each barrel nut by hand to verify that all of the nuts are in contact with the
hanger bars.
NOTE: It is very important to the function of the hanger system that all barrel nuts carry
some load. The installed height of the gantries can vary slightly due to tolerance stack-
ups in the oven sheet metal subassemblies so it is sometimes necessary to adjust the
height of the rail in the hangers. Equal height of all hangers is especially important on
1240 machines where two pairs of supports are only separated by one cell.
If adjustment is needed use the intermediates as the known height reference and make adjustments to the
hangers at the gantries.
To lower the rail height in a hanger loosen the jam screws then unscrew both barrel nuts an equal amount,
up to three full turns of the barrel nuts maximum.
