• 

lock the rotation of the clamp on the right side, operating the handle “16”.

• 

Fasten the adjustment rods in the clamp.

• 

unlock the rotation of the handle “12”, loosening the screw “M”.

• 

activate the probe spring, acting on handle “15”.

• 

Move the carriage forward, so that the adjustment rods rest on the “t” probe 

and the “c” cutter.

• 

operating the handle “12”, move the probe forward or backward, until the 

probe “t” is resting on the adjusting rod “Vt”, the “c” cutter lightly rubs the 

adjustment rod “Vc”.

• 

re-tighten the “M” screw.

3.1.3 lateral stoP adJustMent

• 

the bit carriage is supplied with the factory-set lateral stops, so it is not 

necessary to adjust them again.

• 

however, after replacing the lateral stops, the way to set them would be as 

follows:

• 

support the right side of the lateral stop “n1”, against the internal bushing 

“c1” 

• 

in this position, tighten the “r” screw to fix the lateral stop “n1”.

• 

attach a “long male” type key to the right-side clamp, so that the bit is butted 

against the lateral stop “n1”.

• 

lock the “X” axis of the carriage, operating the handle “14”.

• 

execute a straight groove of approximately 8 mm. of depth.

• 

loosen the screw “Q” that fixes the internal bushing “c2”.

• 

release the key on the right-hand side clamp and attach it to the left side clamp, 

so that the “t” probe is inserted into the slot that we have made in the key.

• 

in this key position, support the left side of the lateral stop “n2”, against the bit 

of the key. 

• 

in this position of the lateral stop “n2”, tighten the screw “r” to fix the lateral stop 

“n2”.

• 

Move the inner bushing “c2”, until it touches the right-side of the lateral stop “n2”. 

• 

in this position of the internal bushing “c2”, lock it by means of the “Q” screw.

• 

now you can unlock the X axis of the carriage, operating the handle “14”

3.2 ENCRYPTION

3.2.1 encrYPtion oF the Mortise KeYs

Fasten the key in the clamp. depending on the type of key we want to cut, the stop of 

the key will be made in one of the following ways:

-  Key with stop on the stem: 

stop against the left side of the clamp.

- SHORT key (male/female) (simple/double probe): 

stop of the right side of the bit against the side left of the cutter and the Probe.

- LONG MALE key (simple/double probe): 

stop against the lateral stop.

 - LONG fEMALE key (simple/double probe): 

stop against the lateral stop. use counterpoints for female key.

-SPECIAL MALE key: with plastic head, with square stem, ......: 

cutter-Probe stop. use counterpoints for male key.

• 

For greater comfort when fastening the keys in the clamps, it is recommended 

to lock the X axis and the Y axis (in this way, the machine carriage stays still). 

it is also recommended to lock the rotation of the right clamp, to facilitate the 

orientation of the key bit.

• 

start the rotation of the cutter, activating the corresponding switch.

• 

carefully bring the keys towards the cutter and the Probe. we recommend 

working slowly, without forcing the cutter.

• 

the round point is achieved by turning the lever “6” (moving the lever from top 

to bottom). this rotation is internally limited. in the case of deep teeth located 

on the right end of the bit, limit the rotation of the lever so that the bit does not 

touch the lateral stop.

• 

For double-bit keys, turn both keys 180º and repeat the operations already 

described.

• 

if during cutting, burrs are produced in the cut key, these will be eliminated 

using the brush that has been provided with the machine for this purpose.
