Outfeed Table Adjustment
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.
Adjust the height of the outfeed table as follows:
1. Disconnect jointer from power source.
2. Carefully number each blade with a marker to
make them easier to differentiate.
3. Place a straightedge upon the outfeed table
and extend it over the cutterhead (Figures 25
and 26).
Planer knives are dangerously
sharp. Do not grab the
cutterhead itself to rotate it! Failure to comply
may cause serious injury.
4. Rotate the cutterhead, using the drive belt or
pulley, until knife number one is at its highest
point. The apex of the knife should just barely
come in contact with the straightedge.
If the apex of the knife number one just makes
contact with the straightedge, no adjustment is
required for the outfeed table. Proceed to the
Setting Cutterhead Knives section.
If the apex of the knife number one comes
below the straightedge (a gap exists) or
pushes the straightedge up, proceed with the
following steps:
5. Loosen both gib lock screws (B, Fig. 18) and
the lock knob (Figure 25).
6. Raise or lower the outfeed table until the
straight edge contacts the knife tip, as shown
in Figure 26. Using the drive belt or pulley,
rock the cutterhead slightly to make sure the
apex of the knife is just barely contacting the
straight edge.
When adjustment is complete:
7. Lock the outfeed table at that setting by
tightening the lock knob (Figure 25) and gib
lock screws (B, Fig. 18). The outfeed table
adjustment is complete.
The outfeed table adjustment is only made against
one knife (blade number one was arbitrarily
selected here). After the outfeed table has been
set at the correct height, do not change it except
for special operations or after replacing knives.
After this adjustment is completed, it is necessary
to proceed to the Setting Cutterhead Knives
section to verify that all three knives are at the
correct height and parallel to the outfeed table.
