4.9.2 Vertical clamp adjustment

The vertical clamp height can be adjusted by the side-handle.

Proceed as follows toproperly position the vertical clamp:

•Loosen the side clamp (see picture 14) by using the

handle and adjust the pressure pad height over the frame.

It is advisable to adjust the height between 5 and 8 mm

above the moulding to avoid any accidental fingers

crushing.

•Tighten the handle once you have reached the proper

position.

•Activate the vertical clamp by pressing halfway down

on the foot pedal and then press the control button or

pressing full down on the footpedal.

•Check that the mouldings to be assembled are properly

clamped.

4.9.3 Horizontal clamp adjustment

The Frontal Clamp (horizontal clamp) has a series of holes in

the flat bar, (see Picture 15) that lock into a peg in the front

channel. Lift the bar to take it out of its initial position and

make it move forward and backward.

To lock the bar it is sufficient to insert it into the proper peg

located in the center of the guide channel.

Proceed as follows to position the Horizontal Clamp correctly:

1. Remove the bar from the peg (lifting it by about 10-15

mm) and move it forward until it touches the mouldings

to be assembled.

2. Back the bar off until it drops into the next available

hole.

TAKE CARE: In case of continued use

without needing to remove the bar from its

position, it is possible to fix it into the peg

using the proper 6mm screw.

During machine transport, it is advisable to

lock the bar using the supplied knob.

4.9.4 Fences adjustment

The Mitre-Mite VN 42 is equipped with a fence composed

of two separate parts.

Each part of the fence (right and left) is equipped with a

knob that allows it to tilt a few degrees.

The use of this fence is suggested for working frames with

irregularities or small round parts on the external side.

If after the frontal clamping is engaged, the mitre of the

frame is not perfect, the tilting fence can compensate such

a fault.

The Mitre-Mite VN 42 can be used for 90°(4 sided frames),

120°(6 sided frames) or 135° (8 sided frames), by setting

the two fence supports properly(see pictures 16-17-18).

To modify the position of the two fence supports, proceed

as follows:

•Remove the external screw by using a 5 mm Allen

wrench.

•Loosen the internal screw and shift the fence until it

reaches the holes located on the working bench.

The exact position of the fence supports can be obtained

with the help of a special template, which was shipped with

your machine.

Make sure that the 120° or 135° angle formed by the two

supports is exactly centered on the internal vertex of V-

nails claw head.

Picture 17

Picture 18

Picture 19

Picture 20

4.9.5 Protective shield adjustment

The machine can be ordered with a protective shield (see

fig. 19) made of transparent plastic material.

Proceed as follows to adjust the protection shield:

1 Position the mouldings to be assembled on the working

bench

2 Loosen the handle whick locks the protection shield

and lift or lower it so it is about 6-8 mm from the

mouldings to be assembled.

3 Tighten the handle to lock the protection shield.

Opening the protection shield causes the

control pedal to be deactivated.

4.9.6 Working pressure adjustment

The working pressure must be adjusted, depending upon the

hardness of the mouldings to be assembled.

Adjusting the regulator allows you to change the clamping

pressure.

Too high of a working pressure can cause a poor junction

and on small-size frames the moulding could be crushed.

Too low of a working pressure can cause an incomplete

insertion of the V-nail into the frame.

The working pressure is adjusted by means of the regulator

on the panel near the pressure gauge (see picture 20).

Proceed as follows to adjust the working pressure:

1. Pull up on the regulator cap by about 3-4 mm to the

unlocked position

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

DO NOT ADJUST the pressure

if the machine is not power

supplied.

The suggested pressures are:

Soft woods (samba,........) 40-50 PSI

Medium (ramin,........) 50-70 PSI

Very hard woods (oak) 70-90 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% to 15 %.

5.2 FUNCTIONING DESCRIPTION

To make a proper junction, the operator must proceed as

follows:

1 Position the mouldings to be assembled on the machine’s

working bench.

2 Set the limit stops.

3 Press the foot pedal half way down to activate the frontal

clamp.

4 Shift the control lever to the 1st inserting point.

5 Press the pushbutton halfway down (or the foot pedal

full down) to activate the vertical clamp.

6 Press the pushbutton full down to insert the V-nail.

If you want to stack 2 or more V-nails in the

same position, you must release the button

halfway and then press it full down to insert

the 2nd V-nail and so on.

4.10 CHECKING OPERATIONS TO BE

EFFECTED BEFORE WORKING

START

Once the machine has been properly installed (like

previously described), check that:

on the working bench

•The magazine is loaded with the type of v-nails suitable

with the mouldings to be assembled

•The adjustment of vertical and horizontal clamps are

correct (chapter 4.9.2 and 4.9.3)

Note: To improve the clamping of highly shaped profiles,

very large or very hard moulding it is possible to order a

felt pressure pad & a magnetic hold down rod. Sometimes

this helps provide better clamping.

•The protective shield is properly positioned (see chapter

4.9.5)

•The working pressure is adequate to the wood hardness

(see chapter 4.9.6)

If you want to insert 2 or more V-nails one

upon the other in the same position, you

must release the pushbutton halfway and

then press it again full down to insert the

second V-nail

b) Assembling positions

It is advisable to operate as follows in order to achieve the

best results in terms of junction quality:

Never drive V-nails near the junction vertex. The

minimum recommended distance from the external

vertex is at least 10 mm.

When you want to make the junction using only one V-

nail, the most suitable position is in the middle of the

moulding (see fig. 21)

In case you want to insert 2 or more V-nails into each

junction, we recommend you to insert the most external

one 1/3 from the external vertex and the most internal

one 1/4 from the internal vertex.

5.4 MACHINE STOP

The machine can only work by pressing the pneumatic foot

pedal. To stop the machine, it is enough to lift off of the

footpedal.

It is possible also to disconnect the fast clutch fitting from

the compressed air.

5.5 MACHINE REINSTATEMENT

The machine reinstatement is effected by pressing the

pneumatic foot pedal.

5.6 PUTTING OUT OF SERVICE

In case on long inactivity periods it is necessary to disconnect

the fast clutch fitting from pneumatic system.

6. MAINTENANCE

6.1 STATE OF MAINTENANCE

The maintenance operations must be performed with the

machine in the conditions described at “state of the machine”

in the tables 6.6.A and 6.7.A

6.2 MACHINE ISOLATION

Before performing any type of maintenance or repair , it is

necessary to isolate the machine from it’s supply sources,

making the following operations:

1) Disconnect the fast clutch fitting from the pneumatic

system.

Once you have finished the intervention & before

reconnecting the pneumatic supply, check to see that all

components and any pneumatic connections are properly

reinstalled.

6.3 SPECIAL PRECAUTIONS

During the maintenance or repair operations we suggest you

proceed as follows:

•Before starting any operation, place a sign “machine

under maintenance” in a well visible position on the

machine.

•Do not use solvents or flammable materials

•Do not step on the machine parts, because they have

not been projected to sustain the weight of persons.

•Disconnect the air supply line.

•Once all the operations are finished, restore and replace

any protections or shields removed or opened.

6.4 CLEANING

The machine structure is simple and robust therefore the

mechanical parts do not require any special maintenance.

It is advisable to follow the rules listed below:

•Regularly remove glue or other residues from the V-nail

head and from the upper part of the driver blade;

•Always keep the V-nails magazine clean & without

residues.

•Remove any residue from the V-nail guide “L” shaped

support.

Do not use water to clean the machine, otherwise metallic

parts may rust.

Before performing any cleaning intervention,

the operator must disconnect the pneumatic

system.
