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.

Picture 14

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.

Picture 15

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 Vnails claw head.

Picture 16

Picture 17

Picture 18

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.

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 counterclockwise 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

Medium

(samba,........)

(ramin,........)

Very hard woods (oak)

40-50 PSI

50-70 PSI

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 %.

Picture 20

Picture 19

Opening the protection shield causes the control pedal to be deactivated.

4.10 CHECKING OPERATIONS TO BE

EFFECTED BEFORE WORKING

START

Once the machine has been properly installed (like previously described), check that:

• The mouldings to be assembled are properly positioned 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

5. FUNCTIONING

4 Shift the control lever to the 1 st

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 2 nd V-nail and so on.

7 Release the pushbutton (or the foot pedal) half way to rearm the driver blade and to release the position brake

8 Shift the control lever to the next inserting point.

9 Repeat steps 4, 5, and 6 as described above.

5.3 TIPS FOR PERFECT JUNCTIONS

a) V-nail types

In order to allow the machine to make excellent quality junctions using different materials, it has been necessary to manufacture different V-nails types for different uses (see attachment D).

V-nails can be classified in three different groups:

14

for soft woods and soft plastic for medium woods

Suggested Vnails code

Suggested Vnails code

SPT

HPT for hard woods

Suggested Vnails code

HPT 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 Vnail, 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.

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 f inished 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.

6.5 LUBRICATION

Use ITW AMP Code Number T064 or equivalent oil

Furthermore, we recommend you lubricate the driver blade every 200 working hours.

Unsuitable lubricants may cause valve seal problems, (seals may become too large) and consequent Valve jamming could occur.

6.6 ORDINARY MAINTENANCE

The following operations must be executed at the times indicated below. Not observing the following instructions exonerate the Producer from any responsibility regarding the warranty.

The operations described here below, even if simple, must be executed by qualified personnel.

The scheduled ordinary maintenance includes overhauls, checks and interventions that will help prevent stops and breakdowns.
