ADJUSTING CUTTINGHEAD
PARALLEL TO TABLE
The cuttinghead is set parallel to the table at the factory
and no further adjustment should be necessary. If your
machine is planing a taper, first check to see if the knives
are set properly in the cutterhead. Then check to see if
the cuttinghead is set parallel to the table as follows:
DISCONNECT MACHINE FROM POWER
SOURCE
.
1. Place gage block (A) Fig. 49, on table directly under
front edge of head casting (B) as shown. Lower
head casting until front edge of head casting (B) just
touches the top of the gage block.
2.
Move gage block (A) Fig. 50, to opposite end of
table, as shown. Distance from table to edge of
head casting should be the same.
3.
Repeat
STEPS 2
and
3
on outfeed end of table.
4.
If head casting is not parallel to table, tilt planer on
its side as shown in Fig. 51. Remove bolt (C) and
loosen bolt (D) Fig. 51, which will allow you to move
the idler sprocket assembly (E) far enough to release
tension on chain as shown in Fig. 52. Remove chain
from sprocket on end of head casting that must be
adjusted. In this case chain has been removed from
sprocket (F).
5.
Turn sprocket (F) Fig. 52, by hand to bring that
corner into adjustment with the other three
corners.
IMPORTANT: THIS ADJUSTMENT IS
VERY SENSITIVE AND IT SHOULD NOT BE
NECESSARY TO TURN THE SPROCKET MORE
THAN ONE OR TWO TEETH
. Turning sprocket (F)
clockwise will decrease the distance between the
table and head casting. Counterclockwise will
increase the distance.
6.
Replace chain being careful not to disturb the
position of the sprockets and replace idler sprocket
assembly (E) Fig. 51.
