- Tracer point with spring mechanism. the tracer point spring mechanism is
only used for cutting dimple keys.
- Tracer point blocked. the blocked tracer point is used to carry out cutting
operations with the slide forward. in general, for cutting wave keys.
to activate or deactivate the tracer point spring mechanism, you just have to turn the
tracer point spring mechanism knob 180º (half turn).
When the tracer point spring mechanism is activated, the tracer point tip is located
slightly below its adjustment position in relation to the cutter. this tracer point position
enables you to insert it gently into the hole in the original key, before the cutter starts
cutting the key to be copied. this avoids any vibrations and sudden movements of the
slide.
to find out the status of the tracer point at any time (with spring mechanism or blocked),
there is an indicator on the machine's keypad-display which provides this information. if
the light is on, the spring mechanism is activated. on the other hand, if the light is off,
the tracer point is blocked.
2.7.5 sPrinG MecHanisM and BlocKinG oF tHe slide on tHe
"X" aXis (5 and 4)
We recommend that you use the spring mechanism for the slide on the "X" axis to carry
out lateral cutting of wave keys.
We recommend you use the blocking of the slide on the "X" axis for cutting or dimpling
in a straight line.
2.7.6 suPPort leVer For tuBular KeYs
the caPri key cutting machine has a fold-away lever on its top-left side which helps to
make cutting tubular keys, wave keys, etc. more comfortable, as it serves as a support
point for the hand activating the slide travel lever.
2.7.7 cutter sPeed (17)
the machine has a speed selector on its right side, which enables you to select the
cutter rotation speed. in general terms, you can say that the rotation speed depends
on the cutter material:
- Position I: to work with an Hss cutter (6,000 rpm)
- Position II: to work with a Hard Metal cutter (11,000 rpm)
- Position O: cutter at rest.

ON-OFF button
Press it for the keypad-display functions to go into actiVe mode. a green light will
appear next to the button.
Press it again for the keypad-display to go into stand-BY mode. a red light will appear
next to the button.
Lighting button
Press it to switch on the lighting diodes (if they are off) or switch them off if they are on.
this button operates independently of the status of the "on-oFF" button.
SPRING MECHANISM indicator
if the blue light is on, this means that the tracer point is in sPrinG MecHanisM ac-
tiVated mode.
if the blue light is off, this means that the tracer point is BlocKed (spring mechanism
deactivated).
MODE button
this button is for activating-deactivating operation of the tracer point vertical ad-
justment system.
tracer Point adJustMent indicators.
the light on the left comes on when the tracer point is touching the key.
the light on the right comes on when the cutter is touching the key.
FORCE visual indicator.
indicates the ideal force to be applied during cutting.
NOTE: in addition to the visual indicator, the force control system also has an audible
indicator that emits a sound when you have achieved the ideal cutting force. this audi-
ble indicator can be activated-deactivated by pressing the Mode and on-oFF buttons
at the same time.
2.7.9 Vertical adJustMent oF tHe tracer Point (15)
each time the cutter-tracer point is changed, the tracer point has to be vertically ad-
justed.
in order to be able to use the tracer point electronic vertical adjustment system, the
keypad-display must be active (when it is active, a green light appears next to the
on-oFF button).
When the keypad-display is active, you can activate-deactivate the tracer point electro-
nic vertical adjustment system by pressing the Mode button.
to vertically adjust the tracer point, proceed as follows:
• secure the cutter and tracer point in their corresponding tool-holders. Make sure
that they have been secured, inserted upwards as far as they go.
• secure two similar keys in the machine clamps.
• release the tracer point spring mechanism (tracer point blocked).
• lower the head, until the cutter and the tracer point rest on the keys in the
clamps. then, one of the following three situations will occur:
LEFT BLUE LIGHT. if only the blue light on the left comes on, this means that
the tracer point is touching the key, but the cutter is not. therefore, you have to
turn the cutter adjustment wheel to the left, until both adjustment lights some on.
RIGHT BLUE LIGHT. if only the blue light on the right comes on, this means that
the cutter is touching the key, but the tracer point is not. therefore, you have to
turn the tracer point adjustment wheel to the right, until both adjustment lights
come on.
LEFT AND RIGHT BLUE LIGHTS. this means that both the cutter and tracer
point are touching their respective keys. this means that the height of the tracer
point has been adjusted.
IMPORTANT NOTE: When adjusting the height of the tracer point, you need to bear
in mind the type of key you are going to cut. if it is a WaVe key, very little force needs
to be applied to the head activation lever (on the visual force indicator no light should
come on). on the other hand, if it is a diMPle key, the blue adjustment lights have to
come on, and the force indicator should indicate the ideal cutting force for dimple keys
(to achieve this, you have to apply a slight force on the head activation lever).
2.7.10 control oF cuttinG Force
the caPri machine has a revolutionary cutting force control system. this is a patented
system, which when you are cutting diMPle keys, indicates the ideal force to exercise
on the head activation lever. it has two indicators for this purpose:
Visual indicator. the ideal cutting force is achieved when the line of lights rea-
ches the white arrow.
Audible indicator. When the line of lights reaches the white arrow, the machine
emits a sound. this audible indicator can be activated-deactivated by pressing the
Mode and on-oFF buttons at the same time.
this cutting force control system enables you to cut diMPle keys with great precision.
You will cut the holes in the key with exactly the same force with which you have
adjusted the height of the tracer point. in this way, you obtain maximum precision in
cutting diMPle keys.
3.- CUTTING
3.1 CUTTING PROCESS
• switch on the machine using the main switch located on the back right-hand side
of the machine.
• to improve visibility in the work area, activate the lighting by turning on the switch
located on the keypad-display.
• With the help of the table provided in this manual, select the cutter and tracer
point necessary to cut the key.
• change the cutter and tracer point.
• Momentarily block the slide at the end of the "Y" axis travel.
• secure the original key in the left side of the clamp, and the key to be cut in the
right side. When securing the keys, bear in mind the following details:
- KeY stoP. it may be a key which is stopped from being inserted further by its
shoulders (Fig. 4.a), or a key stopped by its tip (Fig. 4.B).
- adaPtor. For some very specific types of key, it may be necessary to use an
adaptor.
