4 . 9 ADJUSTMENTS
Seeing as the machine was tested before shipping,
the operator has only to execute the following
adjustments:
4.9.1 Adjustments for v-nails positioning
The Mitre-Mite VN 4 Memory Program is equipped
with a V-nail driver mounted on a movable
carriage. This is controlled by an electric
motor able to fix with extreme precision each
V-nail inserting position.
The maximum carriage stroke is 5.7”. Within this stroke you
can define several inserting positions. These different points
are settled on the program that the operator must input for
each working cycle.
For further information regarding the programs
creation and V-nails inserting positions see
chapter 6.
4.9.2 VERTICAL CLAMP ADJUSTMENT
To guarantee perfect clamping of the mouldings
throughout the several working cycles the machine
is equipped with a double hydraulic clamp.
It allows the adjustment of both position and
height.
4.9.2.A Vertical clamp position adjustment
•Position on the working bench the moulding
to be assembled
•Loosen the (B) handles (see fig 12)
•Shift the cylinders, by sliding them along
the cross-bar.
•Position the cylinders directly over the
moulding to be assembled.
•Tighten the “B”handles (see fig. 12)
•Loosen the “A”handles (see fig. 12)
•From the execution menùpress key F5
•Tighten the “A”handles (see fig. 12)

4.9.2.B Vertical clamp height adjustment
Procced as follows, in order to adjust the
vertical clamp height:
•unscrew by using a 6mm allen wrench the “C”
screw of picture 4.9.2.B
•lift or lower the vertical clamp
•tighten the “C”screw of picture 4.9.2.B
Picture 4.9.2.B

14
4.9.3 Frontal clamp adjustment
The Front Clamp bar has a series of holes in
it. By lifting the bar you can move it from its
initial position and reposition it forward or
backward.
To lock the bar it is sufficient to insert it
into the proper peg in the center of the guide
channel.
To properly position the Horizontal Clamp,
operate as follows:
1. lift the bar from its peg about 10 - 15 mm
and move it forward until reaching the
moulding to be assembled;
2. lower the bar & allow it to drop over the
peg to lock it in the new position.
4.9.4 Fence adjustment
The machine is equipped with a special fence
composed of 2 different parts.
Each fence side is equipped with a knob that
allows it to tilt the moulding supports.
This fence use is recommended to assemble highly
profiled mouldings.
Furthermore, if the moulding rolls forward or
backwards as the front clamps engages, you can
adjust the tilting fence to compensate the
effect.
In addition to 90 degrees junctions , the Mitre-
Mite VN 4 Memory Program can be used also for
6-sided (120 degrees) or 8-sided frames (135
degrees), by properly positioning the back fence
supports.
Proceed as follows to modify the position of
back fence supports:
•use a 5 mm Allen wrench and remove the
outside screw on the fence parts
•loosen the inside screw slightly and position
the fence in the corresponding tapped holes
located on the working area.
The proper positioning of the back supports can
be obtained by using a special template, which
is included with the machine.
Care must be taken to ensure that the 120°or
135°angle is perfectly centered on the internal
vertex of the V-nail head.Use the center line
of the template to do this.
4.9.5Working pressure adjustment
The working pressure must be adjusted to the
hardness of the mouldings to be assembled.
The pressure regulation permits you to change
the clamping pressure of mouldings to be
assembled.
Too high of a working pressure can cause a poor
junction and (especially on small-size frames)
the mouldings can be crushed.
Too low of a working pressure can cause an
incomplete insertion of the V-nails into the
frame.
The working pressure is adjusted by means of
the regulator on the panel near the pressure
gauge (see fig. 13).
Proceed as follows to adjust the working
pressure:
1. Pull up the regulator cap about 3÷4 mm to
unlock it
2. Turn it clockwise to increase the pressure
and counter-clockwise to decrease it.
3. Push the regulator cap back down, to lock it
into position
The suggested pressures are:
Soft woods (samba,........) 30- 40 PSI
Medium (ramin,........) 40 - 60 PSI
Very hard woods (oak) 60 - 80 PSI
The above listed values apply to 7 and 10 mm high V-nails.
Increase the pressure by 10 % for 15 mm high V-
nails.
When stacking 2 or more V-nails, increase the
working pressure by 10/15 %.

In case of continued use without
removing the bar from its position,
it is possible to fix it to the peg
using the proper screws. In case of
shipment, we suggest to clamp the
bar by using the supplied screw knob.
DO NOT ADJUST the pressure
if the machine is not
connected to the air supply
line.
