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 %.
