feed rollers height
It is essential that the feed rollers 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 adjustment
process quicker and easier, we recommend using a
Rotacator for these adjustments (refer to
Accessories
).
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.
Note:
The chip breaker is spring mounted, which allows it
to adjust automatically to the workpiece. No adjustment
is necessary.

Using your Rotacator, find bottom dead center
(BDC) of any knife/insert edge by slowly rocking
cutterhead pulley back and forth, then set Rotacator
dial to "0" (see
Figure.43
).
