Replacing the Mixing Chamber

The Mixing Chamber may require replacement after extended use. When the hole through the mixing

chamber exceeds .090 it should be replaced.

Removing the worn mixing chamber.

1. Remove the DiaLine Head from the Adapter.

2. Remove the orifice retainer, inlet connector, nozzle nut, and collet from the body. Unthread the

setscrew by a few turns that holds the mixing chamber.

3. Push the mixing chamber up and out the top of the body with a .250 dia. pin.

Installing the new mixing chamber.

1. The mixing chamber must be installed with the top of the chamber flush to the top of the bore.

2. Place the orifice retainer in the bore with the cone side up and hold it down with a finger.

3. Slide the new mixing chamber into the body up from the bottom until it is touching the bottom

of the orifice retainer and align the abrasive inlet hole of the chamber with the inlet hole of the

abrasive body.

4. Tighten the set screw to secure the mixing chamber.

5. Reassemble the DiaLine head and thread the head back on the adapter.

4.6 A2 Cutting head

The A2 Cutting head has two abrasive inlets to allow a connection to the head from either side

depending on the system setup and configuration. A nut and plastic collet hold the nozzle in location.

Ruby orifices and long life diamond orifices are available. Diamond orifices include a carbide wear

disc to protect the bottom of the orifice from abrasive wear.

1. Make sure that the top of the cutting head and the bottom

of the adapter are clean, wash out if necessary.

2. Apply a light coat of HP lubricant such as AccuGoop to

the bottom face and threads of the adapter.

3. Install the orifice retainer with the stepped diameter side

down (cone side up) into the cutting head body.

4. Thread the A2 head onto the bottom of the adapter and

torque to seal.

5. Use a 1/4" ID hose for feeding abrasive into the head.

Push the hose onto one of the abrasive body inlet fittings

until it is secured past the ridge. The other fitting must

have a plastic cap installed.

6. Loosen the nozzle nut, slide the nozzle up until it bottoms-

out in the abrasive body, and tighten the nozzle nut.
