2. Cartridge refi lls
Open the cartridge as specifi ed in the instructions: cut the end of the
cartridge thread horizontally (fi g. 4), leaving as much thread as possible
to improve tightening when attaching the cartridge to the front base of
the tube support (pos.8); if there is a seal on the rear section, remove it
completely, together with the anti-humidity cartridge if fi tted.
The use of a special tool is recommended when opening the cartridges;
always avoid makeshift operations using blades, or other sharp edges or
utensils that may injure the operator.
• Disconnect or shut off the compressed air supply.
• Turn the cartridge support tube anti-clockwise to remove (fi g.1)
• Insert the cartridge in its housing
• In the case of model PM/1M tighten the cartridge fully down onto the thread; in the case of model PM/3 with
O-ring, push the cartridge fully down into position (fi g. 2)
• Re-tighten the cartridge support tube until it closes. (fi g. 3).
Always disconnect the gun from the air supply when replacing the cartridges
Take care to cut the smallest amount possible of the thread on the cartridge (fi g. 4), to leave as much thread as
possible to improve tightening when attaching the cartridge. Ensure that the seal (pos. 20) is present, intact and
perfectly clean. Otherwise, replace with the part supplied.
Always check the expiry date of all refi ll cartridges used. The cartridges to be used are those in plastic with the
special large thread 15x2.5 (fi g. 4). If the cartridge specifi cations are not as specifi ed above, it must not be used
Check that the cartridge contains fl uid, sprayable material (Ms polymer), and that the density allows for simple
extrusion; if not, it is recommended to change the type of material with a more fl uid version.
Always fi t cartridges that have no signs of deformation; even a small dent on the cartridge can cause malfunctions
of the gun, and also blockage of the lines due to hardening of the material inside, with consequent damage to the
entire gun.
The gun is equipped with a pre-compression system to enable adaptation to the various cartridges commercially
available. If the cartridge support tube does not attach fully onto the gun, never apply excessive pressure, but
activate a preliminary spray and then tighten the tube down fully
