Adjusting Jointer Table Parallelism
For safe and proper cutting results, the tables must be parallel to the cutterhead. Adjusting them to be parallel is a task of precision and patience, and may take up to one hour to complete. Luckily, this is considered a permanent adjustment and should not need to be repeated for the life of the machine.
Due to the complex nature of this task, we rec- ommend that you double check the current table positions to make sure that they really need to be adjusted before starting.
You can adjust stop bolts on the front of the tables and shim under the back of the tables to adjust them parallel to the cutterhead.
The correct order for adjusting the table parallel- ism is to first adjust the outfeed table parallel with the cutterhead, then adjust the infeed table paral- lel with the outfeed table.
To adjust the jointer table parallelism:
1.Perform the "Checking/Adjusting Table Parallelism" procedure on Page 39, including making any necessary adjustments so the cutterhead and outfeed table are parallel.
2.Place the straightedge halfway across the infeed table and halfway over the outfeed table, and adjust the infeed table even with the outfeed table, as shown in Figure 55.
3.Place the straightedge in one of the positions shown in Figure 56.
Infeed Table to Cutterhead Parallelism on Page 40).
4.Loosen the cap screws shown in Figure 57.

5.While an assistant raises the infeed table, slip shims between the hinged shaft and the jointer base, then retighten the cap screw. Shimming the top position will raise the rear cutterhead side of the table, shimming the lower position will raise the rear infeed side.
6.Repeat Step 3 with each of the remaining straightedge positions and adjust the table front to back using the shims as many times as necessary until the infeed table is parallel with the outfeed table.
7.Set the knives (refer to Page 43).
8.Reinstall the cutterhead guard.
