If the apex of the knife number one comes below the straightedge (a gap exists) or pushes the straightedge up, proceed with the following steps:
5.Loosen both gib lock screws (Figure 22).
6.With the outfeed table handwheel (Figure 21) raise or lower the outfeed table until the straight edge contacts the knife tip, as shown in Figure 23. Using the drive belt or pulley, rock the cutterhead slightly to make sure the apex of the knife is just barely contacting the straight edge.
When adjustment is complete:
7.Lock the outfeed table to this height setting by tightening the gib lock screw (Figure 22). The outfeed table adjustment is complete.
The outfeed table adjustment is only made against one knife or knife insert (blade number one was arbitrarily selected here). After the outfeed table has been set at the correct height, do not change it except for special operations or after replacing knives.
After this adjustment is completed on the model 54A, it is necessary to proceed to the Setting Cutterhead Knives section to verify that all three knives are at the correct height and parallel to the outfeed table. For the model 54HH, proceed to Replacing or Rotating Knife Inserts on page 20.
Setting Cutterhead Knives (Model 54A only)
Note: Before setting knives for the 54A Jointer, the Outfeed Table Height Adjustment should be done to ensure the proper knife height in relation to the outfeed table.
Knives for the 54A cutterhead are adjusted by means of a cam. It is important to note that the entire adjustment is accomplished within one complete rotation (360 degrees) of the cam. A full rotation of the cam will cause the knife blade to move a total of .015” from one extreme to the other. Turning the cam more than one full rotation will not further adjust the knife setting, but will simply begin the adjustment all over again. The knife adjustment procedure is outlined below.
Cutterhead knives are dangerously sharp! Use extreme caution when inspecting, removing, sharpening or replacing knives into the cutterhead. Failure to comply may cause serious injury!
To adjust (refer to Figures 24 & 25):
1. Disconnect jointer from power source.
