1. Compressed
dry air
enters through the rear or bottom of the Gun Handle.
2. The air is directed through the spool valve and into the Rear of the Piston in the Air Cylinder,
moving the Piston (and Mixing Chamber) forward to the
CLOSED
position.
3. In the
CLOSED
position, the orifices in the Mixing Chamber are
NOT
aligned with the Side
Seal ports. The orifices in the Mixing Chamber are exposed to the air/grease chamber in the
Gun Block.
4. Purge air passes through the Spool Valve and the Check Valve, and into the Air Cylinder and
Gun Block.
5. Purge air and residual grease enter the Mixing Chamber and pass through the Mixing
Chamber and PCT, expelling mixed material out of the chamber area in the process.
6. Purge air is also expelled from the PCT in a circular trajectory to keep the tip clean.
