Feed Rollers & Chip Breaker Heights - Grizzly G0815 Owner's Manual

Feed Rollers & Chip
Breaker Heights
It is essential that the feed rollers and chip
breaker are set at the correct distance below the
cutterhead knives at BDC (bottom dead center)
to ensure that the workpiece moves through the
planer evenly and the correct distance from the
cutterhead knives.
To ensure accurate results and make the adjust-
ment process quicker and easier, we recommend
using a Rotacator for these adjustments (see
Accessories, on Page 27).
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
wood to achieve accurate results.

(refer to Adjusting/Replacing Knives on
Page 25 for detailed instructions).
3. Raise headstock at least 4" above table, then
lock it in place.
4. Remove dust hood, top cover, belt covers,
and drive chain cover.
5. Using Rotacator, find bottom dead center
(BDC) of any knife edge by slowly rocking
cutterhead pulley back and forth, then set
Rotacator dial to "0" (see Figure 52).
