ADJUSTING THE FEED RAILS
The feed rails on your PERFMASTER AIR V2 are designed to adjust easily in case of a
problem with crooked feeding. By loosening the feed rail alignment lock knobs you can
move each rail independently to square them to your stock. To maintain an accurate
perf or score, it is important to get the rails as aligned and snug to the sheet as possible
without “squeezing” the sheet, as this will create drag and cause the sheets to hang up
in the rails.
To adjust this correctly, use one rail as your reference, the left (operator side). Place
your stock squarely against it then bring your right rail in and tighten, looking down it
from the rear. Adjust the rail with the skew adjustment knob so it is squared to the
sheet. Then tighten the lock knob, and place your PERFMASTER AIR V2 in perf mode.
Set a sheet in the feeder, and under the feed wheels, then press run.
Check perf by folding over and aligning the perfed edge.
Perf holes should line up within a blade’s width. If they do not line up, adjust rails
accordingly, moving your left rail first and then adjusting the right rail to square the
sheet. This may take a few attempts, but this adjustment is important to produce quality
perf and score jobs.
EXAMPLE:
SQUARING THE FEED RAILS
The constant fine tuning of the rails will make it necessary to bring the rails back to
true “square”. To do this, take a sheet of 8 1/2 x 11” cover stock and place it in the feed
table against the operator side guide. Pressing the sheet against the rail, slide the rail
over so that the front edge of the stock lines up to the front edge of the feed table.
Loosen the feed rail adjustment lock knob, and use the skew adjustment knob to adjust
the rail so that the sheet is aligned with the left to right with the edge. Once this is
done, slide the opposite side guide into position and adjust it to the edge of the sheet.
Your rails should now feed the sheet perfectly aligned providing a straight perf or score.
