A44-P
The pressure regulation allows you to change the clamping pressure
of mouldings to be assembled.
Too high of a working pressure can cause a poor junction and
(especially on small-size frames) the moulding could be crushed.
Too low of a working pressure can cause an incomplete insertion
of the nail into the frame.
The working pressure is adjusted by means of the regulator on the
panel (see fig. 19).
Proceed as follows to adjust the working pressure:
1. Pull up the regulator cap by about 3÷4 mm. This will 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
Picture 4.8.6.1
DO NOT ADJUST the pressure if the machine is not connected to the air supply.
The suggested pressures are:
Soft woods
(samba,........)
1.5 - 2.0 Bar
Medium
(ramin,........)
2.0 - 3.0 Bar
Very hard woods
(oak, MDF)
3.0 - 5.0 Bar
The above listed values apply to 7 and 10 mm high Wedges.
Increase the pressure by 10 % for 15 mm high Wedges.
When stacking 2 or more Wedges, increase the working pressure by 10/15 %.
In order to allow an easy use of the machine tilted back ,the A44-P is
equipped with a ballast cylinder with a regulator (Pict. 4.8.6.3) and a surge
tank (located on the floor stand) that provide an air cushion to balance
the weight of internal components when the machine is tilted.
To obtain an optional regular balancing, set the pressure at:
• 0 BAR, when the machine is flat
• 1,0÷1,2 BAR, when the machine’s tilted
Picture 4.8.6.3
DO NOT ADJUST other pressure regulator not described in this manual: keep them as set at the mfactory
to avoid machine malfunctions.
