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.
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.
