5. Lift the rails up into the hanger bars and secure with barrel nuts and thrust washers. Do not force the nuts
into the hanger slots, they should turn all the way down by hand. Excessive force will gall the stainless
steel nuts and bar slots preventing free movement of the rail for thermal growth. If the barrel nuts bind,
stop and check alignment of the hanger with the rail. Tighten the barrel nuts until they bottom out against
the top of the rail clamps. Make sure that the jam screw in the top of the barrel nut is backed off enough
so that it does not stop the barrel nut before it is fully seated. Once the barrel nuts are tightened tighten
the jam screws.
6. Visually check that all hangers are resting level with the rail, then slide each rail hanger clamp toward the
onload end of the machine until the barrel nuts are approximately 1/16 (1.5mm) from the end of the
hanger bar slots. Use a 3/16 hex key to tighten the rail clamp screws to lock the clamps to the rails.
