3.2.2 Cutting pump keys
• Put the keys into the clamps, taking care that the
blade of the key rests on the front stop of the clamp,
as shown in Figure 9.
• Start the machine and, holding the slide by means
of the handle (M), move the keys towards the tracer
point (I) and the milling cutter (F).
• We recommend that you work slowly, without forcing
the milling cutter. The perpendicularity of the cut is
achieved by directing the slide with the handle (N).
• If the key cutting operation has left some burrs on the
cut key, these can be eliminated with the plane that
the machine has been fitted with for that purpose.
3.2.3 Cutting FO-4P keys, CHU-4G & CHU-5G,
• Put the mortise lock clamps in position (C). Then, put
the key in place so that the blade rests on the 45º
recess the clamp has in its side. This gives the angle to
the teeth of the key. See Figure 10
• Put the key right in until the tip stops on the milling
cutter and tracer point and then cut the teeth.
• Important: Before putting the keys into the clamp,
check their position. The keys leave the factory with a
machined tooth on one of their blades.
3.2.4 Copying the FO-6P key
READING THE CODEOF THE ORIGINAL KEY
(INCLINATION POSITION)
• The original key has 6 copying
indicated by the following letters:
A, B, C, D, E and F, as shown in
For each of these positions, there are
sible inclinations established by means of numbers,
which are indicated below:
1 2
• Inclination number 1 indicates that this position should
not be copied.
Inclination number 2 indicates that there is a small
recess in this position.
Inclination number 3 indicates that the recess is
somewhat bigger in this area.
Inclination number 4 represents the biggest recess
possible.
• It is a good idea to prepare a table showing the incli-
nations in each of the positions, as shown by way of
example below:
POSITION A B
INCLINATION 3 4
NOTE: The series of numbers for the "inclination" is
the code for the key.
COPYING OPERATION
Here is a quick example with the previous reading:

• Place the "inclination marker" (V) in the
3, and by inserting the tracer point in the letter A of
the drum (W), make the corresponding copy. Carry
out the same operation for inclination 4 (top number

4), inserting the tracer point in letter B of the drum (W).
Carry on successively this way until the 6 positions have
been completed.
• Then do the same with the 4 bottom
"inclination marker" (V), thereby copying the other side
of the same face of the key.
• To copy the other face of the key, turn it over and carry
out the same operations, always using the same code,
as the key is symmetrical and therefore has the same
code.
ADJUSTMENT OF SLIDE WITH RESPECT TO MACHINE
The position of the milling cutter and tracer point of the
machine have been adjusted for other slides. Therefore,
this slide requires a number of adjustments, without
distorting the adjustment of the machine itself. 4 adjust-
ments have to be made, in the following order:
1. "LENGTHWISE" adjustment
• Put a blank key into the clamp, and position the "incli-
nation marker" to number 4. Machine the positions A
and F. The machining width should be within the area
established by the lines in Figure
positions. If it is not, you have to adjust the length:
• Loosen the nut (DK-208). Slightly loosen the stud bolt
(DX-40). Remove the stud bolt (EC-250) so that the
drum (W) can be moved until it comes up against the
support (EC-96). Insert the tracer point (I) in the slot
marked by letter A, of the drum (W). Turn the stud
bolt (EC-250), so that it moves the drum W (EC-99)
to the left, until the machine's milling cutter is in the
ideal position in front of the key. Retighten the stud
bolt (EC-250) and the nut (DK-208).
2. "INCLINATION" adjustment
• Put a blank key into the clamp, and position the
"inclination marker"(V) to number 1. The key should
be completely flat, so that if is is brought towards the
milling cutter, the cutter makes a slight mark
centre of the key. See Figure 12. If it does not make a
mark in the centre, you have to adjust the inclination:
• Slightly loosen the stud bolt (S). Centre the key, tur-
ning the clamp by hand. Retighten the stud bolt (S).
3. "DEPTH" adjustment
• Put a blank key into the clamp, and position the "incli-
nation marker" to number 1. Machine any position.
When doing so, you should note that
cutter rubs lightly against the key, but without actually
machining it. If the milling cutter remains distant from
the key or if it actually machines the key, you must
adjust the depth:
• This adjustment is done by means of the screw (J).
4. "ALIGNMENT" adjustment
• Put a blank key into the clamp, and position the "incli-
nation marker"(V) to number 1. Machine the positions
A and F. The two marks made by the milling cutter on
the key should have the same depth. If they do not, you
have to adjust the depth:
• You have to get the part (EC-54) that butts up against
the screw (J) in line with the FORD slide.
• This part can be aligned with the aid of the 2 stud bolts
(DK-197) that are on the back of the "tracer point
support". Undo the 2 lock nuts (DK-207) on the 2 stud
bolts. Rotate the part by means of the stud bolts, until
it is aligned with the FORD slide. Make sure that once
aligned, the two stud bolts are in contact with the
part. Tighten the 2 nuts to lock the stud bolts.
