Inspect / Adjust Jointer Tables
Each jointer has been inspected and calibrated in the factory and should not require adjustments initially.
When a jointer consistently makes problematic cuts, perform these checks, and make adjustments as
needed.
Inspect Outfeed Table Height
1. Disconnect jointer from power source!!
2. Put on leather gloves.
3. Remove cutterhead guard.
4. Move fence assembly all the way back to
expose the entire table.
5. Place a straight edge over the centerline of
the outfeed table so it hangs over the
cutterhead.
6. When the outfeed table height is properly
set, cutters should be barely scraping the
straight edge when the cutterhead rotates.
Follow the next section to make adjustments
as needed.
If the outfeed table height is set properly, jump
to section “ Inspect Outfeed Table Parallelism ” .
Adjust Outfeed Table Height
1. Disconnect jointer from power source!!
2. Loosen the cap screw that locks the outfeed
table.
3. Adjust outfeed table height with the lever.
With a straight edge sitting on the outfeed
table, cutters should be barely touching the
straight edge when the cutterhead rotates.
4. Below the base of the lever, there are two
stop bolts for setting the maximum and
minimum height of the outfeed table.
If these stop bolts need to be adjusted,
loosen the jam nuts, and retighten them
after adjustments.
5. When the height of the outfeed table is
adjusted, tighten the locking cap screw to
lock its height.
