Line throwing gun launcher bleed screw operation

Line throwing gun Launcher Bleed Screw Operation

Each Launcher is equipped with a Bleed Screw–located near the line thrower label on the Launcher.(see fig.2) The Bleed Screw Handle swivels over the Bleed Screw Bolt, to permit the Bleed Screw to be turned without interfering with the Folding Stock.

 

One purpose of the Bleed Screw is to:

• Permit the operator, if necessary, to reduce the operating pressure of the Projectile prior to discharge, as follows:

1. Open the Nozzle Valve to pressurize the Launcher (see page 25), then

2. Rotate the Bleed Screw Handle in a counter-clockwise direction until you hear air escaping, and

3. Monitor the Pressure Gauge until the desired operating pressure is achieved, then

4. Rotate the Bleed Screw Handle in a clockwise direction to stop the escape of air.

 

The second purpose of the Bleed Screw is to:

• Permit the operator to bleed off the pressure in the Mechanism in order to remove a charged Projectile, as follows:

1. Close the Nozzle Valve in the Launcher (fig.15d), then

2. Rotate the Bleed Screw Handle in a counter-clockwise direction until you hear air escaping, and

3. Monitor the Pressure Gauge until the reading is at “0”, then

4. Rotate the Bleed Screw Handle in a clockwise direction to tighten.

5. The Projectile may now be removed by pressing the Safety Knob and pulling the Trigger.
