Oil Fittings

Oil fittings are located on the tops of each handwheel and on each side of the base. Lubricate these fittings with ISO 68 or SAE 20W oil by depressing the ball with an oil can nozzle and squirting once or twice.

Adjusting Gibs

The gibs control play in the longitudinal and cross feed table movement; they are pre-adjusted at the factory and typically need no adjustments until the machine is well used. If table movement is too tight, make sure the locks are fully released. Next, make sure the bedways are thoroughly cleaned of rust preventative and lubricated with oil.

Both the longitudinal table and the cross feed table have gib adjustment screws (see Figure 49 for the location). Turn the gib adjustment screw clockwise to tighten the gib or turn counterclock- wise to loosen the gib.

To adjust the gibs:

1.Turn the gib screw one full turn in the neces- sary direction for tightening or loosening.

2.Test the gib tension by turning the handwheel and moving the table back and forth. Repeat Step 1 as necessary.

NOTICE

When adjusting gibs, the goal is to remove unnecessary sloppiness without causing the slides to bind. Loose gibs may cause poor finishes on the workpiece and may cause undue wear on the slide. Over-tight- ened gibs may cause premature wear.
