• For DC Style controllers that use a push to connect fitting you will
need to cut the male quick connect adapter off from the supplied airline.
• To install the air line into DC style controllers you will need the black
adapter (Part number 5779K712) shown below that comes supplied
with the unit. Simply install the adapter first, then firmly insert the cut
5/32” (4mm) hose to operate.

General Operating Instructions
• To retract the pistons after depleting the cartridge remove the cap
and the cartridge from the retaining cap. Manually push the pistons
back into the unit to reset them. You do not need to remove the unit
from the airline prior to retracting the pistons. You will need to do this
prior to inserting a new cartridge to begin dispensing again. For best
safety practices ensure the foot pedal or purge button is not
accidentally actuated during the retract process.
• When not in use remove the cartridge from the retainer cap overnight
or between shifts to prevent any potential adhesive from dripping
back into the piston shaft and cap. While most cartridges should not
leak there is always the potential for residual adhesive that could mix
and cure causing the inability to unscrew the cap.
