4.Close needle valve #4 (see Figure 47), and then open it three full turns.

5.Place a waste oil container under the dump line (see Figure 47), and turn the pump on. The waste oil will be pumped into the waste oil container. When the reservoir is empty, wipe the reservoir out with clean rags.

6.Using a 4mm hex wrench, remove the pump mounting screws and the pump.

7.Invert the pump and inspect the suction screen (see Figure 48). Clean the screen with mineral spirits as required to ensure full flow.

Removing Table

Backlash

Longitudinal table travel is controlled by a handwheel connected to a cable and a set of pulleys, which in turn are connected to the table. Through time, the cable may stretch slightly. When this occurs, table/handwheel backlash will be detected. To remove this backlash, a simple adjustment can be made.

To remove table backlash:

1.Turn the oil pump ON for a few minutes to lubricate the ways.

8.Reinstall the pump and add 5-quarts of oil.

9.Back-out needle valves #1, #2 and #3 14-turn.

10.Turn the pump ON. Next turn the pressure needle valve #4 inward until it is fully seated.

11.Unscrew needle valve #4 slowly until three drops a second of oil are seen returning to the reservoir from the port directly above the reservoir and left of the leadscrew.

12.Reinstall the cover.

2.Move the table from left and right a few times to distribute the oil.

3.Select a pulley at either end of the table, and loosen the pulley cap screw (see Figure 49) with a 6mm hex wrench, raise the dust skirt, and rotate the pulley clockwise until tension is felt in the cable.

4.While holding the pulley and cable tight, tighten the cap screw.
