It is essential that the feed rollers, chip breaker,
and pressure bar are set at the correct distance
below the cutterhead inserts at BDC (bottom
dead center) to ensure that the workpiece moves
through the planer evenly and the correct
distance from the cutterhead inserts.
To ensure accurate results and make the
adjustment process quicker and easier, we
recommend using a Rotacator for these
adjustments (refer to Page 37).
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 and ensure
both boards are the exact same height.
