-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.
5.2.2 ENCRYPTION OF FRONTAL KEYS
• Lock the rotation of the right-hand side clamp. To do this, operate handle "16".
• Place the key in the throat cross-section of the clamp.
• Place the key so that the asymmetric bit is facing downwards of the clamp.
• Push the key until the back part of the bit reaches the front face of the clamp.
• It is important that the key bit is as horizontal as possible.
• Keeping these details in mind, fasten the keys in the clamps.
• 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).
• Start the rotation of the cutter, activating the corresponding switch.
• Bring the keys towards the Cutter and the Probe. We recommend working
slowly, without forcing the cutter.
• If during cutting, burrs are produced in the cut key, these will be eliminated
using the brush.
5.2.3 ENCRYPTION OF VERTICAL CUTS
• Replace the BIT carriage with the clamp carriage for vertical cuts.
• For greater comfort when changing these carriages, it is recommended to lock
the X axis and the Y axis of the machine. This way, the main carriage of the
machine remains still.
• The BIT carriage and the clamp carriage for vertical cuts are released and
fastened by means of the handle "13".
• The BIT carriage is pulled out by pulling it to the right side.
• The clamp carriage for vertical cuts is introduced from right to left, until an
internal stop is felt.
• Fasten the virgin key and the key to be encrypted in its corresponding clamps,
operating the "S" handles.
• The bit of the key must stop against the lower part of the clamp.
• The key bit must rest against the vertical wall of the clamp.
• Start the rotation of the cutter, activating the corresponding switch.
• With the lever "W" in its highest position, bring the keys to the cutter "C" and "T" probe.
• Insert the probe into the groove of the key to be cut.
• Gently move lever "W" downwards. We recommend working slowly, without
forcing the cutter.
• Repeat this same operation, as many times as necessary until completing the
encryption of the vertical cuts of the key.
• If during encryption, burrs are produced in the cut key, these will be eliminated
using the brush.
• Once you have finished cutting: lock the slide and remove the keys.
N.B.: If the key cutting operation has left some burrs on the cut key, these can be
removed using the brush the machine is fitted with for this purpose.
6.-MAINTENANCE
The Volga Bit duplicator machine requires no particular maintenance plan. Nonetheless, cer-
tain parts should be checked regularly and eventually replaced once they become worn. This
particularly includes the cutter, the brush, the tracer and the belt.
Maintenance operations should be carried out by qualified professionals with the necessary
protective equipment for working safely.
The instructions provided in this manual should be followed carefully when performing any
maintenance tasks and the following instructions should be followed in general:
The machine should be switched off and disconnected from the power supply
before starting any maintenance operations. The operator should make sure that nobody can
access the machine.
Do not perform any maintenance operations while the machine is in operation.
Original spare parts should always be used. The "CE" mark is only guaranteed
when original spare parts supplied by the manufacturer are used.
After replacing a component, make sure that the corresponding screws are in
their correct position.
NEVER USE COMPRESSED AIR! We recommend using the small brush supplied
with the machine for keeping the clamps and carriage assembly free from metallic swarf.
We recommend using protective oil (WD40 or similar) to protect the metal parts
of the machine against oxidation, applying oil to the clamps, tracer, rails, etc.
6.1 REPLACEMENT OF THE CUTTER
To replace the cutter, proceed as follows:
Turn off and unplug the machine.
1) Insert rod "A" supplied with the accessories into the hole that blocks the rotation
of the head. To find it, turn the head by hand.
2) With the fixed key "B" which is also supplied together with the accessories, loosen
nut "E". Take into account that nut "E" has a left-handed thread.
3) Remove the worn cutter "C".
4) Install the new cutter "C", and tighten it by tightening nut "E". Check that the
cutter is mounted with its cutting teeth pointed in the correct position. Take into
account that the cutter rotates clockwise.
5) Remove rod "A".
6) After replacing the cutter, it is recommended to carry out the "Cutting depth
adjustment". The steps for doing so are explained in other sections of this manual.
