Operation

5.Verify the pressure relief/recirculation valves on the resin pump is set to the pressure relief/recirculation position.

10.Turn the catalyst pump pressure relief/recirculation valve to the dispense position.

FIG. 17

6.Turn the main air supply pressure regulator fully counter-clockwise to relieve pressure and set to zero pressure. See FIG. 18.

7.Turn the main air supply ball valve to the open posi- tion. See FIG. 18.

8.Slowly turn the main air supply pressure regulator clockwise until the pump starts to move and will change-over by itself. Never turn past 20 psi (0.14 MPa, 1.4 bar). See FIG. 18.

11. Disengage the trigger lock on the gun. See FIG. 21.

To reduce the risk of exposure to the dispensed mate- rial mist, when performing the following step use a pail lid with a hole to dispense through. Seal around hole and gun with a rag to prevent splash back.

To reduce the risk of skin injection, be careful to keep fingers away from front of gun.

To reduce the risk of fire and explosion, use a grounded pail.

12.Purge air from resin and catalyst hoses: with a grounded bucket below the gun, press the gun against the side of the bucket and pull the trigger to dispense. Continue dispensing until air-free fluid is dispensed from both ports on the front of the gun. See FIG. 21. The pump air pressure may need to increase slightly until the material begins to flow.
