10.6Knife replacement

Use caution when placing hands near the cutterhead. Knives are extremely sharp. Failure to comply may cause serious injury.

1.Disconnect machine from power source. (Unplug)

2.Remove screws securing the dust hood and dust chute.

3.Remove dust hood and dust chute.

4.With a marking pen, label each knife on the cutterhead one, two, and three for easy identification.

5.Loosen all lock bar set screws on knife number one.

6.With the brass bar and a mallet, carefully tap on each end on the outside of the set screws for all three lock bars on knife number one. This loosens the taper fit of the lock bar.

7.Carefully remove knife.

8.Remove lock bars.

9.Repeat steps 5-8 for knives two and three.

10.Clean cutterhead of any wood chips, pitch, saw dust, and any other debris.

10.7Adjusting infeed roller and outfeed rollers for planing

As a general rule of thumb, the infeed and outfeed rollers are set 1/8” below the cutterhead (not the knives) at the factory. To check the feed rollers:

1.Disconnect machine from power source. (Unplug)

2.Make two blocks out of scrap 2x4 lumber using the dimensions noted.

3.Mark each block as shown in Figures 10 and 11.

Figure 10

Figure 11

4.Lower the work table to allow cutterhead block to slide freely between the table and the cutterhead. Note: Cutterhead may have to be turned by hand to rotate a blade out of the way.

5.Adjust the table height so the block can be inserted between the table and the cutterhead with minimum resistance.

6.Remove the block. Do not raise or lower the table at this point. It will affect the final result.
