To ensure accurate results and make the adjust- ment process quicker and easier, we recommend using a Rotacator (see Page 20) for these adjust- ments.

If a Rotacator is not available, a pair of even-sized wood blocks and a 0.40" feeler gauge can be used, but care must be taken to achieve accurate results.

To set the height of the infeed and outfeed roll- ers and the chip breaker using a Rotacator:

1.DISCONNECT THE PLANER FROM THE POWER SOURCE!

G1021X 15" Extreme Series Planer

2.Lower the table at least 4" below the head casting and lock the table in place.

3.Remove the dust port, top cover, and belt cover.

4.Using a Rotacator, find BDC of any carbide insert edge by slowly rocking the cutterhead pulley back and forth, and set the Rotacator dial to zero, as shown in Figure 29.

Rotacator.

5.Move the feed speed knob to neutral to allow the infeed roller to rotate by hand.

6.Place the Rotacator under the right-hand side of the infeed roller and find bottom dead cen- ter on a serrated edge by rocking the infeed roller back and forth.

7.Adjust the height of the infeed roller on the same side as the Rotacator to the specifica- tion given at the beginning of this procedure, using the zero setting of the Rotacator as a reference point. Figure 30 shows the jam nut and set screw for adjusting the roller height.

8.Repeat Steps 6 & 7 on the left-hand side of the infeed roller.

9.Double-check and micro-adjust both sides of the infeed roller, then carefully lock both sides in place.
