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 table is set parallel
to the cuttinghead as follows:
1.
Disconnect machine from the power source.
2.
Place gage block (A) Fig. 59, on table directly under
front edge of head casting (B) as shown. Lower head casting
until front edge of head casting {B) just touches gage block.
3.
Move gage block <A) Fig. 60, to opposite end of table,
as shown. Distance from table to edge of head casting should
be the same.
4.
Repeat STEPS 2 and 3 on outfeed end of table.

5. If head casting Is not parallel to table, tilt planer on its
side as shown in Fig. 61. Remove bolt (C) and loosen bolt (D)
Fig. 61, wliich will allow you to move the idler sprocket
assembly (E) far enough to release tension on chain as shown
in Fig. 62. Remove chain from sprocket on end of headcast¬
ing that must be adjusted. In this case chain has been removed
from sprocket (F).
6.
Turn sprocket (F) Fig. 62, by hand to bring that corner
into adjustment with 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
headcasting. Counter-clockwise will increase the distance.
7.
Replace chain being careful not to disturb the position
of the sprockets and replace idler sprocket assembly (E) Fig.
61.
