1. Remove the gun air regulator (31) from the nipple
(30) coming off the air manifold (29). Do not re-
move any parts from the regulator. Save the
regulator for use in step 4. See Fig. 6.
2. Install a 101180 Gauge (P) and 100509 Plug (Q)
on a 104267 Air Regulator (R). Screw a 166999
Elbow (S) into the outlet port of this air regulator,
and screw a 162453 Nipple (T) into the elbow.
3. Screw the branch of the 103475 Tee (L) onto the
nipple (30) at the air manifold (29). Install a
156877 Nipple (M) in each open port of the tee.
Screw a 158683 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 (27) from the optional outlet port
of the fluid filter (25). Install a 100840 Elbow (V)
and 162453 Nipple (T) in its place. See Detail A of
Fig. 7. This is the fluid connection for the second
gun.
6. Connect the fluid and air hoses to the guns as
explained on page 6 (see Detail D of Fig. 7).
