choose the pair of counterpoints, depending on the type of key. 

note: to help identify them, they have different engravings on the end of the head.

the counterpoint is inserted inside the carriage bushing, manually threading it. stop 

inserting it when you see it has reached as far as the key (do not Force it).

2.6.4 MaXiMuM length oF KeY

the Volga-bit machine has been designed in such a way that there is no limitation 

on the length of the key to be cut.

it has clamps at two heights, in such a way that the clamp on the left side does not 

prevent the attachment of any key length.

2.6.5 Probe sPring

the Volga-bit machine has the handle “15” that activates the probe’s spring.

the probe spring facilitates the insertion of the probe between the teeth of the key, 

for the subsequent guidance of the key towards the cutter.

2.6.6 locKage oF the X aXis

the Volga-bit machine has the handle “14” that locks-unlocks the movement of the 

carriage in the X direction.

the locking function of the X axis is useful when we want the carriage to move 

forward and without the possibility of lateral movements. it is also useful when we 

want to cut keys with the optional clamp carriage for vertical cuts.

locking the X axis also facilitates the operation of fastening-releasing the keys from 

its clamps, by preventing the carriage from sliding to the sides.

2.6.7 Y aXis locKing

the machine also has a slight lock at the end of the course of the Y axis, to prevent 

the carriage from sliding forward during the operation of fastening-releasing the keys 

from its clamps.

Just bring the carriage of the machine to its most extreme position towards the user, 

so that we can see that the carriage is locked by means of a small spring. 

to unlock the carriage, simply push the carriage lever forward slightly.

2.6.8 claMP carriage For Vertical cuts (oPtional)

the Volga-bit machine has a special carriage (optional purchase), to make vertical 

cuts of some models of keys. it is called clamp carriage for vertical cuts.

to swap the bit carriage and the clamp carriage for vertical cuts, the machine has the 

handle “13”, which locks-unlocks the carriage.

before performing the carriage swap operation, it is very useful to lock the X and Y 

axes of the machine.

the carriages are removed and inserted on the right side of the machine.
