ust flip over both left and right top vise jaws and clamp them in place with the large knurled knobs
located below the painted key clamping knobs.
Make sure your vise jaws are clean (no chips) and as you secure the top vise jaw in the “step” jaw
configuration-be sure to push the back edge of the step top jaw firmly and flat against the stepped face
of the bottom vise jaw when tightening the large knurled located below the painted key clamp knob.
See figure 1 below.

When clamping keys in the “step” jaw be sure to open the jaws ONLY enough to slide the key in place
so it will be clamped against the top vise jaw’s “step”. Opening the vise jaw too wide will allow the
key to pass under the step part of the top jaw and the key will be clamped improperly.
Please see below for more vise jaw information
C) Keys are always gauged with the full-function flip-up key gauges. Never attempt to bottom
shoul
der gauge a Medeco key against the vi
se jaws.
D)
Always remember to flip down your key gauges before cutting a key. Failure to do so may damage th
e
Key
gauge and key gauge shaft with the cutter wheel
.
E)
Your stylus and cutter head should be in the Center cut position. Look down onto the key to
be
dupl
icated and note which cuts are straight or angled cuts. Switch ON your m
achine and gently
release th
e carriage and operate the “stick-shift” lever until the stylus is right over the left edge of th
e
first center cut. Ease up on the carriage and m
anipulate the carriage controls to make a smooth gentle
cut
down the left edge of the “V” cut in the key and then gently up the right side of the “V” cut in
the key. Cut the entire single “V” cut
but do not cut over the top of either edge of the “V”
cut you are
duplicating. You m
a
y reverse the cut to “clean” it up.
Pull gently back on
the carriage when the single cut is completed. Note if there is another center cut on
the key and duplicate it also. Duplicate all center cuts one-at-a-tim
e and cut ONLY
those Center cuts
at this tim
e. Remember-do not cut over the top of the “V” and into another adjacent cu
t. Duplicate
only one cut at a time.
F)
Lock back your carriage. Turn OFF your machine. Rotate the stylus and rotate the cutter head and
lock it in place for left cuts.
