TEST PROCEDURE

1.Remove the input power to the wire drive unit.

2.Using the 3/8 in. nutdriver, remove the case cover.

3.Locate and remove plug J84 from the control board. Refer to figure F.4.

4.Thread plug J84 and associated leads through the vertical baffle. Cut any necessary cable ties.

5.Locate and disconnect the motor leads (#551 and #550) at the quick connects. Cut any necessary cable ties.

6.Using the Phillips head screwdiver, remove the #67 lead from the conductor block.

7.Using the needlenose plers, disconnect the gas hose from the brass gun connector block.

8.Using the 7/16 in. socket wrench, remove the four mounting bolts, lock washers, and flat washers from the plastic base insulator.

9.Carefully slide and remove the entire gear box, drive motor, and wire drive assembly from the wire feeder case. Note insulation placement for reassembly.
