b. Rotate the depth control knob (7) counterclockwise one line on the depth control scale.
Tighten the depth control locking knob (6).
c.
Turn the speed control on low and run a few test sheets through the machine.
d. Check and repeat steps 2 and 3 if necessary until correct perforation is achieved.
Setting the depth control perforation is too shallow:
a.
Loosen the depth control lock knob
b. Rotate the depth control knob clockwise one line at a time on the depth control scale and
test each time control is moved until proper perforation is achieved.
c.
Re-tighten depth control lock knob.
Caution – After the setup is made, do not disengage or re-engage the perforator from
between the backup hubs when machine is in operation mode. This action could cause
severe damage to the perforator blade. To re-engage perforator follow Section III “Slot
Perforator Setup” instruction.
IV.
Slit Perforator Setup (Figure 4)
The setup for slit perforating is the same as the setup for slot perforating, with the following
exception:
Only one backup hub is required. (The sharp edge of the hub should tightly contact the
perforator blade teeth.) The stripper blade is required.
V.
Scoring Wheel Setup (Figure 1 and 5)
Note – The backup hub has two grooves, a wide groove for heavy stock and a narrow
groove for light weight stock. Select the groove that provides the desired scoring width
for the stock being run.
Loosen the depth control locking knob (6) and set the depth control (7) to the maximum open
position.
Mark a piece of stock at the position to be scored and place it on the feed table (1) with the
marked edge toward the scoring wheel. Set paper guide as described in Section I and set
retarder as described in Section II.
Loosen the scoring wheel (upper shaft) and backup hub (lower shaft) set screws. Align the
scoring wheel blade and appropriate backup hub groove to the mark on the paper. Tighten the
backup hub set screw. Using the depth control, lower the scoring wheel into the appropriate
backup hub groove. Align the scoring wheel blade in the center of the backup hub groove and
tighten the scoring wheel set screw (figure 5).
Place a sheet of paper stock onto the feed table (1). Rotate the hand wheel (5) to feed the
paper. Use the depth control adjusting knob (7) to set the proper scoring depth. Tighten the
depth control locking knob (6) when properly set. Set the guide fingers into position.
If the score position is incorrect, follow the paper guides adjustment in Section III.
