Adjusting Feed
Roller Heights
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 adjust-
ment 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.
