Figure 53. Planer component recommended
clearances. Illustration is not to scale.
It is essential that the feed rollers, chip breaker, and
pressure bar (see Figure 53) are set at the correct
distance below the cutterhead knives/inserts at BDC
(bottom dead center) to ensure that the workpiece
moves through the planer evenly and the correct
distance from the cutterhead knives/inserts.
To ensure accurate results and make the adjustment
process quicker and easier, we recommend using a
Rotacator for these adjustments (refer to Page 36).
If a Rotacator is not available, a 6-foot-long 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.
