GATE TIMER
The adjusting knob for the gate timer is located on
the back of the machine's left side cover. It controls
the amount of time that the stop gate is held down
each cycle after the stitches have been driven into the
booklet. Longer booklets need more time to get
past the gate, and the next cycle cannot start until the
gate has returned.
For 11" x 17" paper, set the knob as shown. The
knob can be left in this position for any other paper
size with feed rates up to 2,300 booklets per hour.
For faster feed rates with smaller paper, turn the
knob to the 8.5x11 position.
The stitch
gate must be down long enough for book-
let to pass over. If the gate comes up too soon, the
gate limit swich could get tripped causing a double
stitch. Turn the knob slightly clockwise.
If the stitch gate stays down longer than necessary
and the feed rate is high, booklets will will pass
through the stitching station without getting stitched.
Turn the knob slightly counter clockwise.
Once the adjustment is fine tuned, the knob can be
calibrated by loosening its set screw and aligning the
mark on the knob with the appropriate paper size.

Proper Fold
Finally, if the fold is not quite square (see below), the
lock nuts can be adjusted individually.
Important: Adjust the lock nuts as described below
only as a last resort. First, carefully adjust the side
guides and hand crank per page 8.
If the stitches are off the fold (see below), open the
booklet flat and measure to see if the stitches are
centered on the length of the paper. Turn the knob
until stitches are placed precisely on the center of the
paper. Next, remove the rear cover and locate the
two lock nuts below the back end of the secondary
table.
Turn both nuts equally in small increments until
booklets will fold precisely on the stitches.
ADJUSTMENTS
BOOKLET SQUARENESS
Check the finished booklet. If the stitches are prop-
erly located on the fold, but the fold is off center,
adjust the gates by turning the hand crank until sets
will fold precisely in half.
