1. Remove the gun air regulator (18) from the nipple
(24) coming off the air manifold (28). Do not re-
move any parts from the regulator. Save the
regulator for use in step 4. See figure 5.
2. Install a 101–180 Gauge (P) and 100–509 Plug
(Q) on a 104–267 Air Regulator (R). Screw a
166–999 Elbow (S) into the outlet port of this air
regulator, and screw a 162–453 Nipple (T) into the
elbow.
3. Screw the branch of the 103–475 Tee (L) onto the
nipple (24) at the air manifold (28). Install a
156–877 Nipple (M) in each open port of the tee.
Screw a 158–683 Elbow (N) onto each nipple.
4. Install the air regulator removed in step 1 onto one
of the elbows (N). This is the air control for the first
gun. Install the air regulator assembled in step 2
onto the other elbow (N), so both regulators are
facing the same way. This is the air control for the
second gun.
5. Remove the plug (10) from the optional outlet port
of the fluid filter (8). Install a 162–453 Nipple (T) in
its place. See Detail A of Fig 6. This is the fluid
connection for the second gun.
6. Connect the fluid and air hoses to the guns as
explained on page 7 (see Detail E of Fig 6).
