Depth is adjusted by moving the stylus forward or backward by means of a knurled adjustment knob
located at the back of the stylus. The adjustment is secured by the "T-turn" knob located on the top of the
stylus holder.
To begin the adjustment you must loosen the "T-turn" knob. Use your hand to turn the knurled thumb— turn
the adjustment knob about 1 full turn—viewed from the front of the machine turn the knob to your LEFT. See
figure 15.
NOTE:
The stylus is spring loaded and you must push against the tip of the stylus to compress the spring.
Secure the two matched key blanks—one in each vise jaw. See figure 15.
PLEASE NOTE:
Clamp the keys
into the vise jaws with about 1/32" gap between the bottom shoulder of the key and the left-side edge of the vise
jaws.
DO NOT
bottom shoulder the keys into the vises—there may be a small radius in the corner of the key
blank's blade and bottom of the shoulder area.
Clamping in this area may ANGLE the key blank in the vise and throw off your adjustment.
With the keys clamped in the vises and with the stylus adjusted forward about 1 turn—carefully bring up the
carriage and position it so the key in the left vise jaw
LIGHTLY contacts
the stylus about in the middle of the
key blank's blade. Now push more firmly against the carriage and allow the left hand key to compress the
stylus all the way back. Hold the carriage in this position during the adjustment process.
Observe that the cutter wheel misses the key blank in the right vise by carefully turning the cutter
BACKWARDS
by hand—the cutter teeth should miss the blade. The reason for turning the cutter backwards
is to prevent any cutter teeth from removing material off the key blank's blade before you make your
adjustments. Turning the cutter backwards will bump the key blank without cutting it—if the stylus was not
adjusted forward enough to miss the key blank.
Upon verifying that the cutter wheel misses the key blank—you may switch ON your key machine.
Take the 1" x 4" piece of writing pape
r y
ou made earlier and hold one end of it between the spinning cutter
Wheel and the bade of he key blank.
Use your hand to slowly and carefully back off on the knurled adjustment knob—at the same time we
recommend that you slowly move the 1" x 4" piece of paper from side to side along the blade of the key blank
to assist you in detecting when the cutter wheel's teeth first contact the paper. When the cutter wheel first
contacts the paper the paper will be shaved almost without any sound—you must back off the stylus very slowly
for this to work.
Once you have the cutter wheel touching the paper you may slow down the procedure to very small
increments. Stop when the piece of paper is cut through to the last few fibers. You have accurately
adjusted the depth of cut on your key machine.
