To put a Radius on the corner of your product:
With the Press Handle in the up position as shown, slide the product to be cut along the guide until
it comes to rest against the inside edge of the Outer Knife.
Hold the product in place firmly with one hand.
Make sure to keep fingers away from the Knives.
Pull down on the handle so that the Outer Knife cuts through the product.
A quick snapping motion near the end of the cut will improve the quality of the cut.
Raise the Press Handle to the up position and slide the product out from under the Outer Knife.

Inspect the quality of the cut. The radius on the product should come to an almost perfect blend
against the straight edges. The edges of the cut may have a small burr. This burr should not be
excessive. If this burr is excessive, the Outer Knife may need adjusting, sharpening, or
replacement. (See Page 06)
Applying a small amount of light machine oil to your product before cutting and occasionally
applying some light machine oil to the blade on the Table Assembly will prolong the life of the
blade.

It is important to keep the Outer Knife in proper alignment or it
can be pressed down at an incorrect angle causing unneces-
sary stress on the knife. This can cause the Outer Knife to dull
quicker and/or break.
Remove the Table Assembly from the CR-60 Arbor Press
before adjusting the Outer Knife (See Page 05).
The Outer Knife should be perpendicular (90 ) to the surface
of the Table Assembly. Loosen the Cam Adjustment Screws
on the Cams using the 5/64” Hex Key provided. Rotate the
Cams as needed so that they hold the Outer Knife in proper
alignment.
