Connect 1/8-inch tubing from a solenoid valve to the trigger air fitting on the manifold.
For applications faster than 600 cycles per minute, install the optional quick-exhaust
valve at the air inlet. To do this, remove the air fitting and install a 1/4-in. NPT nipple in
the manifold, then install the quick-exhaust valve on the nipple, and the air fitting in the
quick-exhaust valve.
Remove the nozzle nut from the end of the gun. Install your nozzle in the nozzle nut, then
screw the nut onto the gun. Tighten the nozzle nut securely.
Flush the gun periodically to keep it clean and free of contaminants. As required,
disassemble and clean the gun modules and replace any worn parts.

NOTE: Make sure the nozzle and seat sealing surfaces are clean before installing the
nozzle.
Make sure the trigger air is clean and dry. If you are operating the gun at high cycle rates
for long periods of time, install an air lubricator in the air supply line. This will extend the
life of the air piston seal.
