Feed Rollers and
Chip Breaker
The feed rollers and the chip breaker are factory
set for general planing. If you need to alter the
settings or reset them after maintenance, these
components can be adjusted at the same time,
assuming that the knife height is set correctly.
The standard setting for the chipbreaker is
0.020" below the cutterhead knife at bottom
dead center. The infeed roller and outfeed roller
should be set to 0.040" below the cutterhead
knife at bottom dead center.
To accurately perform this adjustment, you
will need a dial indicator (not included). Refer
to Planer Accessories on Pages 34 and 35 for
more details.
To adjust the feed rollers and the chip
breaker, make sure you have adjusted the
cutterhead alignment as outlined on Page 14
first, then do these steps:
1. UNPLUG THE PLANER!
2. W1723: Cut two wood boards that are the
same height and are at least 20" long.
W1724: Cut one board only.
3. W1723: Place both boards across the table
as shown in Figure 26
.
W1724: Place the board in the center of
the table and cutterhead.
4. Remove the belt cover and lower the
cutterhead casting until the board(s) barely
touch the knife edge.
5. Rotate the cutterhead pulley until a knife
is at BDC (Bottom Dead Center, see
Figure
27) as indicated by the knife tip barely
grazing the board, making a slight rubbing
sound.
6.
W1723: Lower the feed rollers onto the
boards using the feed roller adjustment
setscrew shown in Figure 28.
W1724: Position the board to the far left
and lower the feed rollers onto the board,
then move the board to the far right and
lower the feed rollers onto the board.
