Ram Dial Calibration

The guard and spindle should be removed. Referring to Figure 12:

1.Loosen the infeed fence lock knob (E), then turn the infeed ram dial (D) counterclockwise to bring the infeed fence (F) back all the way until the limiter setscrew (P) touches the head casting (M). Then retighten the lock knob (E).

2.If necessary, loosen two setscrews on the infeed ram dial (D) with a 2mm hex wrench and align the zero on the dial with the indicator mark. Then tighten the setscrews.

3.Next, loosen the outfeed fence lock knob (B) and turn the outfeed ram dial (A) counter- clockwise to bring the outfeed fence (C) all the way back.

4.Place a straightedge (G) on the table against both fences.

If both fences are flush with the straightedge (K) and the outfeed ram dial (A) indicates zero, no further action is necessary.

If alignment is necessary (J):

5.Slide the outfeed fence (C) aside to reveal the limiting setscrew (P) on the fence casting (N).

6.Loosen the hex locking nut (O) with a 10mm wrench and back out the limiting setscrew (P) with a 3mm hex wrench to permit a sufficient backward and forward adjustment range for the outfeed fence (C).

7.Slide the outfeed fence (C) back onto the casting and secure.

8.Loosen the outfeed fence lock knob (B).

9.While maintaining pressure (H) on the straightedge (G) against the fences (C, F), adjust the outfeed ram dial (A) until both fences are in-line (K).

After proper alignment is made:

10.Slide the outfeed fence (C) aside again.

11.Turn the limiting setscrew (P) in (turn cw) until it comes in contact with the head casting (M)

12.Tighten the hex locking nut (O) with a 10mm wrench while maintaining the setscrew position with the 3mm hex wrench.

13.Replace the outfeed fence and secure.

14.Loosen the two set-screws(2mm hex wrench) on the outfeed ram dial (A) and align the zero on the dial with the indicator mark. Then tighten the setscrews.
