Knife Down Mode; Electric Eyes; False Clamp Plate - Challenge CHAMPION 305 Instructions And Parts Manual

7.0 Operation

7.13 Knife Down Mode

The knife down mode is used to send the knife and clamp to the down position without returning up.
This provides a way for the service technician to adjust the knife. To send the knife down or up, enter
maintenance mode, "A". Select either Knife Down or Knife Up, and then press the cut buttons. When
sending the knife down, the cut buttons must be held until the motor stops.

7.14 Electric Eyes

The electric eyes prevent reaching into the cutting area while a cut is being made. If the beams are
broken while a cut is being made, the knife and clamp will return to the up position.

7.15 False Clamp Plate

To prevent marking on pressure sensitive jobs, a false clamp plate has been included (installed) with
your machine. This plate attaches to the bottom of the clamp. It is secured from the front of the
cutter with three set screws.
removing the false clamp plate. NEVER attempt to install or remove the false clamp plate while the
machine is running. Remove all tools and stand clear when reconnecting power.
To install:
1. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout, page 6.)
2. Position the false clamp plate under the clamp, (Figure 10). The locator pegs are positioned
to the rear of the cutter and are set into holes in the bottom of the clamp.
3. With a 1/8" Allen wrench, back off the setscrews in front of the clamp and raise the plate up to
the bottom of the clamp. It may be necessary to bring the clamp down onto a stack of paper
with the foot pedal in order to access the far left setscrew. Raise the false clamp plate evenly
or it will have a tendency to bind. When the plate has been raised into position and is flush
with the bottom of the clamp, tighten the setscrews to hold the plate in position.
4. Make sure that all tools have been taken off the cutter table, reconnect the power, and turn
on the machine.
