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 headcasting 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.
IM-
PORTANT: 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 headcasting.
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.
