REPLACING THE CUTTERS
WARNING! ENSURE MACHINE IS UNPLUGGED BEFORE UNDERTAKING ANY MAINTENANCE
•
Remove the three screws holding the case on the machine (one each side and one at back)
then carefully lift the case off the machine
•
Locate the cut-out on the shaft that runs between the two cutters and insert a 4mm allen
key (or similar) to lock the cutter shaft in position
•
Undo the nut holding the cutter on (turning in anti-clockwise direction) and remove cutter
and washer
•
Replace with new cutter, reusing the existing washer and tighten nut back on in clockwise
direction
MACHINE ADJUSTMENT
WARNING! ENSURE MACHINE IS UNPLUGGED BEFORE UNDERTAKING ANY MAINTENANCE
The machine calibration should be checked on a regular basis and especially after replacing the
cutter. There are two types of calibration, axis calibration which is regulation of the position of the
key left to right and depth calibration which obviously regulates the depth of the cuts
CYLINDER CALIBRATION
Axis Calibration:
Insert identical key blanks with shoulders on front and back into both jaws, lining them up with the
back shoulder against the jaw on Side A.
When correctly calibrated the key set guide should touch both shoulders and the tracer and cutter
should hit the shoulders simultaneously.
If the key set guide is out of alignment:
•
Loosen the allen screws on the triangular guides
•
Adjust until they are both touching the key shoulders
•
Re-tighten the allen screws
If the cutter and tracer are out of alignment:
•
Loosen the two large allen screws on the tracer housing
•
Adjust the position of the tracer left or right until the tracer and cutter are both touching the
key shoulders
•
Re-tighten the screws
Depth Calibration:
Insert identical key blanks with shoulders on front and back into both jaws, lining them up with the
back shoulder against the jaw on Side A.
When correctly calibrated, the cutter should skim the surface of the key on the right whilst the
tracer is making contact with the key on the left.
