the same manner.
11.After all four knives are set with the screws just snug, back out and tighten the six screws
(F)against the slot starting with the end screws first and then the center screws until the knife is securely held in the cutterhead. Tighten the remaining three knives in the same manner.
After replacing and checking knives, CHECK AGAIN carefully. Make certain the direction of knives is correct and all
Checking Work Table Parallel to Cutterhead
The work table is set parallel to the cutterhead at the factory and no further adjustment should be needed. 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 work table is set parallel to the cutterhead. Proceed as follows:
1.Disconnect machine from power source.
2.Place the gauge block (A, Fig. 21) on the work table directly under front edge of head casting (B, Fig. 21). Make slight contact by gently raising table.
3.Move the gauge block to opposite end of working table. NOTE: Distance from the working table to edge of the head casting should be the same.
4.Check the back of the work table in the same manner.
Adjusting Work Table Parallel to Cutterhead
If the work table is not parallel to the cutterhead, perform the adjustment procedure as follows:
1.Disconnect the machine from power source.
2.Tilt planer on its side to expose underside of base, as shown in Fig. 22.
3.Remove bolt (A, Fig. 22) and loosen bolt (B, Fig. 22) which will allow you to move the idler sprocket assembly (C, Fig. 22) far enough to release tension on the chain.
4.Remove chain from the particular sprocket on corner of base that must be adjusted.
5.Turn the sprocket by hand to bring that corner into adjustment with the other three corners. NOTE: Turning sprocket clockwise will increase the distance between the working table and headcasting;

decrease the distance. This adjustment is very sensitive and it should not be necessary to turn the sprocket more than one or two teeth.
6.When adjustments are correct, replace chain around corner sprocket, slide sprocket (C, Fig.
22)back to
22)and replace and tighten bolt (A, Fig. 22).
