with each other.
Possible Solution
1. Completely loosen the table lock.
2. Loosen/reset table positive stops.
Possible Solution
1. Align outfeed table with cutterhead knife at top dead
center (Page 15).
2. Reduce/eliminate downward pressure on that end of
workpiece.
1. Align outfeed table with cutterhead knife at top dead
center (Page 15).
1. Inspect workpiece for knots and grain (Page 22); only
use clean stock.
2. Adjust one of the nicked knives sideways; replace
knives (Page 33).
3. Slow down the feed rate.
4. Take a smaller depth of cut. (Always reduce cutting
depth when surface planing or working with hard
woods.)
1. Check moisture content and allow to dry if moisture is
too high.
2. Replace knives (Page 33).
1. Adjust one of the nicked knives sideways; replace
knives (Page 33).
1. Slow down the feed rate.
2. Adjust the knives so they are set up evenly in the
cutterhead (Page 33).
1. Hold board with even pressure as it moves over the
cutterhead.
2. Take partial cuts to remove the extreme high spots
before doing a full pass.
3. Surface plane one face so there is a good surface to
position against the fence.
4. It may take 3 to 5 passes to achieve a perfect edge,
depending on the starting condition of the board and
the depth of cut.
1. Recalibrate the jointer in this order:
a. Set the infeed and outfeed tables parallel with
each other (Page 36).
b. Set the knives (Page 33).
c. Set the outfeed table height to the knives (Page
38).
d. Calibrate the fence stops (Page 40).
