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.
