5- USE
5.1
See 4.1 for connection to the pneumatic air feed
5.2
Before using the gun, always check:
5.2.1
The opening of the feeding system air flow regulator.
5.2.2
The opening of the pressure regulator on the gun.
5.3
See 4.2 and following points for bag or cartridge refill.
5.4 Use the control lever to activate the gun and start working.
5.5
Disconnect the air feed to stop using the gun; if some material is left inside the cartridge, close it at the front to avoid
product dry up.
6- ADJUSTMENT
6.1
Adjustment of extrusion speed and incoming air capacity
Tighten the flow regulator ring nut clockwise to obtain a gradual closing of the air passage and therefore a reduction of
extrusion speed. Vice-versa unscrew the ring nut counter-clockwise to obtain a gradual opening of the air passage and therefore
an increase of extrusion speed.
6.2. Adjustment of the gun thrust
The standard operating pressure of the gun is from 4 to 8 BAR according to material density. In case of extrusion of a very thick
material or a greater density of the product because of a lower temperature in the work environment, directly adjust the
feeding system pressure regulator. Increase air pressure to increase gun thrust.
7- RESIDUAL RISKS
• Air jet: it mainly occurs when releasing the lever. In that moment, the air contained in the material holder tube is unloaded
through the outlets. Pay attention not to put it close to eyes and ears; pay attention to the presence of dusts and dangerous
volatile substances. Always use safety glasses and in case of volatile dusts, use appropriate individual protection devices to
protect the respiratory system. Check their efficacy with the substances involved.
• Lesions to hands: it may mainly occur during loading and/or ordinary maintenance operations, the threads and the use of
cartridges and bags opening tools can cause cuts or abrasions. Always use safety gloves.
• Tube whiplash: it mainly occurs when disconnecting the gun from the main system. The disconnected gun tube can move
suddenly and unexpectedly; always use the disconnector on the main system before disconnecting the gun.
8- CLEANING AND ORDINARY MAINTENANCE
to be carried out by the operator
When carrying out cleaning and ordinary maintenance operations, the gun shall not be connected to the feeding system.

4.4.1
Disconnect or shut off the gun from the air supply, turn the front ring nut (2) anti-clockwise and remove from the gun.
4.4.2
Extract the cartridge from the material holder tube (7).
4.4.3
For safety purposes, refit the front ring nut (2) turning it clockwise through two turns only, then turn the pressure regulator
anti-clockwise to the end of its stroke; connect the gun to the air supply, keeping the trigger pressure and then gradually
unscrew the regulator clockwise until the gun and adaptor move forward; when these elements reach the front ring nut,
shut off or disconnect the air supply.
4.4.4
Turn the front ring nut anti-clockwise.
4.4.5
Remove the adaptor with care.
4.4.6
Use a 5 mm Allen key to to screw on the bag pressing cone clockwise, tighten it fully down avoid excessive pressure.
4.4.7
Turn the front ring nut (2) clockwise.
