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.
