using the proper screw.

When shipping the machine, it is advisable

to fix the bar using the supplied knob.

4.8.4 Working pressure adjustment

The working pressure must be adjusted to the hardness of

the mouldings to be assembled.

The pressure regulation allows you to change the clamping

pressure.

Too high of a working pressure may cause a bad assembly

junction, & on small-size frames the moulding can be

crushed.

Too low of a working pressure may cause an incomplete

insertion of the V-nail(R) into the frame.

The working pressure is adjusted by means of the regulator

on the panel near the pressure gauge (see fig. 19).

Proceed as follows to adjust the working pressure:

1. Pull up on 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

a) V-nail(R) types

In order to allow the machine to make excellent quality

junctions using different materials, it has been necessary to

manufacture different V-nail(R) types for different uses (see

attachment D).

V-nails(R) can be classified into three different groups:

for soft woods and

soft plastic

for medium woods

for hard woods

Suggested V-

nail(R) code

Suggested V-

nail(R) code

Suggested V-

nails(R) code

b) Assembling positions

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

best results in terms of junction is quality:

Never drive V-nails(R) 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 oneV-

nail(R), 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(R) 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 remove your foot from the pedal.

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

Incase on long inactivity periods it is necessary todisconnect

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 the “state of the

machine” table (tab 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 supplying sources,

by making the following operations:

1) Disconnect the fast clutch fitting from the pneumatic

system.

Once the maintenance is finished the & before you reconnect

the pneumatic supply, ascertain that all components and

any pneumatic connections are properly reinstalled.

6.3 SPECIAL CAUTIONS

During the maintenance or repair operations is suggested to

proceed as follows:

•Before starting any operation place a sign “machine

under maintenance” in a highly visible position.

•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.

•Onceall the operations are finished, restore and properly

place the protections and shields that were 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:

•Regularlyremove glue or other residues from theV-nail(R)

head and from the upper part of the driver blade;

•Always keep the V-nail(R) magazine clean & without

residues.

•Remove any residue from the V-nails(R) guide “L” shaped

support.

Do not use water to clean the machine, otherwise metallic

parts may rust.

Beforeperforming any cleaning intervention,

the operator must disconnect the pneumatic

system.

6.5 LUBRICATION

Use preferably CASTROL MAGNA GC 32 or equivalent oil( ITW/AMP part number T-064).

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

Unsuitable lubricants may cause to the valves seal problems (seals may become too large) and consequent

jamming of them.

6.6 ORDINARY MAINTENANCE

The following operations must be performed at the times indicated below. Not observing the following instructions exonerate

the Producer from any responsibility regarding the warranty.

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