The suggested pressures are:

Soft woods (samba,........) 30-40 PSI

Medium (ramin,........) 40-60 PSI

Very hard woods (oak) 60-80 PSI

Picture 18

In case of continued use without needing
to remove the frontal clamp from its
position, it is possible to fix it into the peg
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 counter­clockwise to decrease it.

3. Push the regulator cap back down, to lock it into position

5.2 FUNCTIONING DESCRIPTION

The machine has only one possible operating mode:

• Manual operation by using the pneumatic footpedal.

Press the foot pedal half way down to clamp the moulding.
Press the foot pedal full down to drive the V-nail

To assemble a corner, you must operate as follows:

1 Set the inserting positions, using the fence locking

clamps

2 Place the mouldings on the working bench. Move the

fence & the moulding to the first inser ting position.

3 Adjust the vertical clamp height and position.

5.3 TIPS FOR PERFECT JUNCTIONS

a) V-nail

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

for soft woods and
soft plastic

for medium woods

for hard woods

b) Assemb ling 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
minimum recommended distance from the external
vertex is at least 10 mm.
When you want to make the junction using only one V­nail
moulding (see fig. 21)
In case you want to insert 2 or more V-nails
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.
