Powermatic 54HH, 54A operating instructions Determining Correct Table Height

Determining Correct Table Height

The Outfeed Table Height Adjustment section tells you how to set the correct table height with respect to the cutterhead knives or knife inserts. This section explains how to determine if the outfeed table needs adjustment based upon the cuts being produced.

When you receive the jointer, the knives have been pre-set at the factory. However, the height and parallelism of the knives with the outfeed table should be checked and any needed adjustments made before putting the jointer into operation.

The outfeed table and cutterhead knives (Model 54A only) are correctly adjusted when all three blades are parallel to the outfeed table and all three blades are set at the same height in the cutterhead.

Outfeed table too high – If the outfeed table is too high, a curved finished surface results (Figure 29).

Outfeed table too low – If the outfeed table is too low, the work will have a gouge, or snipe, at the end of the cut (Figure 30).

Outfeed table at correct setting – Figure 31 illustrates the correct setting of outfeed table level with the knives. The workpiece will rest firmly on both tables with no open space under the finished cut.
