Adjust Table Parallelism/Coplanarity
Adjusting table parallelism and coplanarity take time, precision, and patient. The entire process can take
over an hour or more. Check the amount of misalignment against tolerance before making adjustments.
For best results, a long and precise straight edge is required for adjustments.
Measurement Tolerance
Outfeed Table / Cutterhead Parallelism <= 0.004”
Infeed / Outfeed Table Parallelism <= 0.01”
1. Disconnect the jointer from the power source!!
2. Remove the depth stop knob.
3. Remove all four metal panels that conceal the parallelogram mechanism.
4. Each panel is secured by two cap screws, which are
covered by plastic caps. Use a straight head screwdriver
to remove the plastic covers on the panels. For panels
1,3, and 4, loosen the hex cap screw with a 5mm hex
wrench, and the panels can be lifted.
To remove panel #2, the cap screws must be removed.
Use a magnetized hex wrench for this step so the screws
won’t fall into places that are difficult to reach.
