Turning Off The Hydraulic Motor; Jogging Aid; Pre-Clamping; Air Table On/Off - Challenge CHAMPION 305 Instructions And Parts Manual

7.0 Operation

7.8 Turning Off the Hydraulic Motor

The hydraulic motor will turn off after a few minutes (depending on setting) without any activity. The
hydraulic motor can also be shut off manually by pressing and holding the left cut button.

7.9 Jogging Aid

All Champion cutters include a jogging aid as standard equipment. The jogging aid allows the
operator to load and align stock without placing hands or arms under the clamp and knife area. Load
and align the paper against the side guide, (Figure 9), then square it to the backgauge for cutting.
Figure 9
Additional jogging aids can be purchased by contacting your authorized Challenge dealer.
Always remove the jogging aid from the table before making a cut.

7.10 Pre-Clamping

All Champion cutters are equipped with a low pressure clamping feature which allows the operator to
clamp paper before beginning the cut cycle. To use this feature, press the footswitch until the clamp
comes down on the paper. While holding the foot switch down, press the cut buttons. Release it
once the cut has been completed. Although this is low pressure clamping, avoid placing hands under
the clamp at all times.

7.11 Air Table ON/OFF

If your machine is equipped with an air table, it can be turned on and off by pressing the "D" soft key .

7.12 Adjusting the Clamp Pressure

DO NOT set the clamp pressure below 300 psi. Pressures below this
will not allow the auto-cycle to operate properly, and the knife will come down before the
clamp. Severe lacerations and stock spoilage could result.
A pressure reducer valve and gauge located inside the left door housing on the front of the cutter
below the table. By adjusting the pressure reducer valve, clamping pressure can be set (see
Hydraulic Adjustments section) to a maximum of 1400 psi for heavy stock or large reams to a
minimum of 400 psi for pressure sensitive jobs like carbon or NCR sets. For pressure sensitive stock
using the false clamp plate is also recommended.
