To ensure accurate results and make the adjustment pro-
cess quicker and easier, we recommend using a Rotacator
(see Page 21) for these adjustments.
If a Rotacator is not available, a 6' 2x4 cut into two even
sized pieces and a feeler gauge set can be used, but care
must be taken when jointing the blocks to achieve accu-
rate results.
To set the height of the infeed and outfeed rollers,
chip breaker, and pressure bar using a Rotacator, do
these steps:
1. DISCONNECT THE PLANER FROM THE POWER
SOURCE!
2. Make sure the knives are set correctly with the knife
gauge.
3. Lower the table at least 4" below the headstock and
lock the table in place.
4. Remove the dust port, top cover, and belt cover.
5. Using your Rotacator, find BDC of any knife edge
by slowly rocking the cutterhead pulley back and
forth, and set the Rotacator dial to zero, as shown
in Figure 26.
6. Place the Rotacator under the right-hand side of
the infeed roller, and find bottom dead center on a
serrated edge by rocking the infeed roller back and
forth.
