i. Unbolt the Pneumatic Control Head from the Agent Cylinder Discharge Valve.
ii. The piston of the control head will be locked in the “fired” position, and it must be reset.
iii. To reset the control head, use a small flat tool to depress the small plunger ball on the side of the
extended brass piston while simultaneously pushing the piston back into the head.
iv. Do not attempt to unscrew the small plunger from the brass piston.
v. The piston should be pushed back into the fully retracted position while depressing the plunger ball.

i. Remove the large retaining ring from the bottom of the Control Head (Figure 1).
ii. With a 5/32” Allen wrench (or smaller) inserted through the cross-drilled hole in the tapered piston, pull the piston
assembly out of the control head body (Figure 1).
iii. The thin circular disk and the small spiral retaining ring (replacement p/n 14037) must be removed from the piston
assembly. To do this, with the Allen wrench, unscrew the small tapered piston from the large brass piece (Figure
2). Do not use a vise, as this could damage the part.
iv. Once the small tapered piston is removed, simply slip the thin circular disk and the small spiral retaining ring off
the back end (Figure 2).
v. Re-assemble the Control Head, as shown in Figure 3. First, tighten the small tapered piston back onto the large
brass piece. Make sure that it bottoms onto the brass part, and is hand-tight with the Allen wrench. The piston
assembly is to be pushed all the way into the control head body.
vi. Hold the thick circular disk with the groove facing up (Figure 3). Drop the small spiral retaining ring into the groove.
vii. The thin circular disk is to be placed over the thick circular disk, and the three components are to be inserted over
the piston assembly (by holding the control head body inverted, as shown, it is easier to insert the parts) (Figure 3).
viii. With all of the components in place, and the small spiral retaining ring visible and loosely held between the two
plates, reinstall the large retaining ring to hold the assembly together (Figure 3)
