Upgrading to New Top Jaw
Red Knob Operation
Tighten the red knob on the Obverse key sections or
loosen it enough to let the top jaw move up to grab into
the high groove of C145, or anything in between.
Black Lever Operation
Pro-Lok changed the red knob to a black clutching lever
in 1998, before Everest™ keys existed.
The lever can only swing about 180° before hitting the
body of the machine. If the Blue Punch is used only to
cut one type of Schlage key section, the lever’s travel
may be set for fast secure clamping every time.
The black lever does not allow the top jaw to travel from
its lowest position (for Obverse keys), to an intermediate
position (for clamping most of the Everest C Family keys),
to the highest position required (for C145). Commercial
locksmiths who cut a variety of Schlage key sections daily
may find the continuous lever adjustment inconvenient.
On most machines, the lever must be specifically adjusted
for each of the three clamping positions.
Use the following procedure to back the screw out for
Everest keys or to tighten the screw for Obverse keys:
1. Lift the lever against spring pressure to disengage it
from the screw.
2. While disengaged, swing the lever to the left or right
without turning the screw.
3. Let go of the lever and it snaps back into
engagement with the screw.
Upgrade Package 40-074
A newly designed top jaw, red knob, spring, finishing
washer and regular washer can be obtained from your
Schlage or Pro-Lok distributor.
Changing the top vise jaw has no effect on the accuracy
of the machine. If the machine exhibits mechanical
problems or cannot cut keys accurately, please contact
your Pro-Lok distributor to arrange for your machine to
be rebuilt.

Upgrading Machines With a Red Knob
1. Unscrew the old knob.
2. Remove the old top jaw.
3. Install the new pieces. Install the jaw so the end with
the longer angled portion is toward you. The end with
the shorter angle has a lip to engage in the groove of
the key section.
4. Screw on the new red knob.
Long Angle
Upgrading Machines With a Black Lever
1. Swing the lever as far to the right as it will go. Lift up
against spring pressure to disengage it from its screw.
2. Swing the lever back as far to the left as it will go and
let it down to engage the screw.
3. Repeat this process as many times as necessary to
unscrew the screw completely and remove the lever.
A hex wrench may be helpful.
4. Remove the lever, spring, washer and top jaw.
5. Install the new jaw so that the end with the longer
angled portion is toward you. The end with the
shorter angle engages the groove in the key milling.
6. Reinstall the black lever or install the new red knob
depending on your preference: The red knob screws
into place. If reinstalling the black lever, use an Allen
wrench to start the screw, then reverse the process
used to remove the lever. To adjust the lever's final
position and rotation, clamp a single key or key blank
of the key section you will cut most frequently.
