6.1 Preset the Backgauge
The backgauge must be preset whenever power has been off and should be done occasionally if the
machine is being used frequently. The machine should be preset at least once every eight hours for
average use. A graphical representation of the instructions for presetting is found on the indicator
label on the right-hand side of the front tabletop. The machine will cut more accurately if the
backgauge is preset on a regular basis.
To preset the machine:
•
Bring the backgauge to its forward position by turning the hand wheel clockwise until the
backgauge stops.
•
If the machine is on, turn off the power and then turn it on again. Only dashes will be
displayed. Press the Preset button on the tabletop until the appropriate units are displayed
(inches or millimeters). During normal operation, this button switches between English and
Metric measurement mode. This can be done at any time. A test cut should measure 1.31
inches (1-5/16") or 3.3 cm.
6.2 Set the Cutting Dimension
Turn the hand wheel until your cutting dimension is displayed on the digital indicator. The indicator
may be switched between inches and millimeters by pressing the button to the left of the indicator.
This is also the preset button. When moving to a longer cut dimension, the backgauge should be
moved past the cut dimension then brought forward to the cut position. Use the thumb wheel lock on
the front face of the machine base to lock the backgauge in position.
6.3 Load Paper
Lift the front hood and jog the stock against the backgauge. Challenge recommends centering the
stock on the backgauge to ensure square cutting. The side-guides may not be precisely square to
the backgauge and knife although the backgauge and knife are parallel. A jogging aid has been
provided in the toolkit. The jogging aid is used to tap the pile flush against the backgauge without
reaching under the knife and clamp.
6.4 Make the Cut
To make the cut, close the front hood then press the two cut buttons simultaneously. The cut buttons
are located on each side of the machine. The hood must be closed in order to cut, and the cut
buttons must be pressed within ½ second of each other. It will take a moment for the machine to
begin its cycle after the cut buttons have been pressed. Hold in the cut buttons until the knife has
made a full stop into the cut stick. Release the cut buttons. The knife and clamp will return to their
original position. If you release the cut buttons before the cut is completed, the knife and clamp will
return to their original position. Open the hood, discard the any trimmings or remove the cut stock. If
the machine will not execute a cut cycle see Section 9.0 Appendix C- Troubleshooting.
6.5 Emergency Power Shut-Off Switch
The front face of the machine has a red mushroom button with a yellow backer. Pressing this button
at any time will cut-off all power to the machine. The knife and clamp will stop. If the machine will
not cycle, first check to make sure the emergency power shut-off switch is on.
