3 MACHINE DESCRIPTION
The BRAVO III with EZ-Jaw is a professional cutting machine for flat keys used with cylinder locks for
doors, cars and cruciform keys. The main parts of the machine are described below:
• CONTROL PANEL
The control panel with 2 controls is located on the left-hand side of the BRAVO III with EZ-Jaw key-
cutting machine: the start-up switch for the motor (P) and the push button for the brush (M) (fig. 5, page
6).
• MOTOR AND TRANSMISSION UNIT
The motor (U) is located on the back of the BRAVO III with EZ-Jaw key-cutting machine, under the
central cover.
Motor speed is that more suitable for the materials to be cut. The transmission unit is placed to the right
of the motor.
By means ofa belt undera protective cover(T), the transmissionunit powers the movement ofthe brush
(I) and cutting tool (A).
• MOBILE UNIT
The mobile unit (D), consisting of the clamps, is fitted to the horizontal movement carriage controlled by
lever (L) and is provided with a handle (V) on the top of which can be found the carriage release button
(Q).
The carriage movement, along a double shaft on bearing brasses, allows high precision movements
which greatly facilitate all cutting operations.
The carriage is fully protected by the overhead cutting unit structure which avoids the accumulation of
dust and chippings from the work process.
The BRAVO III with EZ-Jaw is completely safe when used properly. However, for greater safety, two
safety devices are provided:
- an automatic braking mechanism for the carriage slide, activated in the key-locking position.
- an automatic carriage releasing device, linked to the return of the gauges to the idle position,
which activates the cutting tool only when the carriage is released.
The cutting machine is designed with a ramp along which chippings can fall into the special chipping
tray (N), easily removed for emptying and cleaning.
• CUTTING UNIT
The cutting unit contains the actual working parts of the BRAVO III with EZ-Jaw key-cutting machine,
which operate together to cut and finish keys "read" from the originals. The working parts are described
below:
Brush
The brush (I) is used to eliminate burrs from the cuts and is made of non-abrasive material.
Cutting Tool
The cutting tool (A) is the part of the BRAVO III with EZ-Jaw used for cutting key blanks from the tracer
point’s reading of the cuts on the original key. The cutting tool is in HSS super rapid steel or hard metal
and is covered by a transparent plastic shield (H) which provides protection for the operator.
Tracer point
The tracer point (B) is placed on its own support (B1), to the left of the cutting tool. It has micrometric
regulation which makes it possible to adjust the cutting depth quickly and accurately. The tracer point
regulating knob (O) and the nut (O1) for registering zero are included in the unit. The original key-
reading unit is complete with the tracer point locking screw (J) and the screw which holds it to the
support (J1).
Clamps
The clamps ensure perfect grip on keys placed flat or sideways (fig. 6).
The clamps (E) are placedin front of the tracer point and cutting tool respectively to grip the original key
and the key blank. With the clamps, cutting is rapid and precise for various types of keys and a wire
range of optional accessories can be used on the machine.
Anatomical knobs (F) with which to secure the keys are fitted on top of the clamps. The knobs are
designed so that only slight pressure is needed to give perfect grip on the keys.
On the lower side of the clamps are the calibration tabs (K). The rotating drum for the gauges (R) is
placed at the centre of the carriage, between the two clamps.

the stops.
b) to take the callipers into contact with the keys, rotate the drum (R) towards you (away from
you to return to the ideal position)
ATTENTION: the carriage will be released only if the callipers are in the ideal position.
3) Release the carriage by lowering the knob (V) and pressing the push button (Q) right down (fig. 9,
page 13).
4) Raise the carriage and take up to the cutting tool.
5) Take the flat part of the key into contact with the cutting tool and tracer point (fig.11).
6) Turn the cutting tool by hand in the opposite direction to rotation and check that it skims the
adjusting key at different points.
7) If necessary regulate the cutting tool depth with the micrometric tracer point, as follows:
a) loosen the screw locking the tracer point (J2) (fig. 14, page 15).
b) turn the knob (O) clockwise to move the tracer point forwards.
c) turn the knob (O) anticlockwise to move the tracer point backwards (each mark on the
graduated drum equals a variation of 0.002").
8) If necessary, repeat the regulation operation a number of times. Tighten the screw (J2) before
checking skimming (point 6).
9) Zero the tracer point by taking the reference index on the handwheel (O1) to the white mark on
the graduated drum, as described below:

6 CUTTING OPERATIONS
ATTENTION: for complete safety during the cutting operations, take the following precautions:
• Always work with dry hands.
• Check that the machine is properly earthed.
• Wear protective goggles even if the machine has a protective shield over the cutting tool.
• Start the motor (switch P) only after completing the operations on the carriage (securing the
keys, etc.).
• Keep hands away from the cutting tool in motion.
6.1 Key cutting
When BRAVO III with EZ-Jaw has been turned on by means of push button (C), it is ready for cutting
but the cutting tool is not rotating (because the carriage is held in the idle position). Now the original key
and the blank can be placed in the jaws, ready for cutting.
S ECURING THE KEYS IN THE JAWS
Position the key blank (right-hand jaw) and original (left-hand jaw), ensuring that:
a) the keys are resting properly on the bottom of the jaw.
b) the key stop butts against the gauge (K) (fig.15) or the key tip is up against the stop bar
(fig.16).
c) close the jaws by turning the knobs (F).
Fig. 15
Fig. 16
T O TURN THE CLAMPS :
- With loosened handle (F) a light rotation of the clamp is sufficient (gripping by the 2 jaws) to turn
it to the required side. Alignment is automatic and guaranteed by the mobile pressure device (E1).
