Adjusting Gibs
Figure 27. Gib adjustment.
The function of the gibs is to take out play in the
table, and cross slide, and column without causing
the slides to bind. The gibs are pre-adjusted at the
factory and should not need further adjustment
until many hours of machine use. If the movement
seems too tight at first, make sure the locks are
fully released. Next, make sure the bedways are
thoroughly cleaned of rust preventative and lubri-
cated with oil.

Each gib has multiple lock nuts and set screws
that need to be adjusted. Make your adjustments
equally and in small increments.
To adjust the gibs: (see Figure 27)
1. UNPLUG THE MILL/DRILL!
2. Loosen the lock nuts.
3. Move the table and slightly tighten each
set screw. When properly adjusted, the gib
should offer slight resistance without bind-
ing.
4. Tighten the lock nuts.
After some period of time, the carbon brushes
on the DC motor will need to be replaced.
Always replace the brushes in pairs. Use part #
P0463242.
