10.11 Planer Table Adjustment
Checking Planer Table Parallel to Cutterhead
Refer to Figures 24 and 25:
The planer table is set parallel to the cutterhead
by the manufacturer and no further adjustment
should be needed. If your machine is planing a
taper, first check to see if the knives are properly
adjusted in the cutterhead (see
sect. 10.4, sect.
10.4, Setting Knives at Correct Height and
Parallel to Outfeed Table
) and make adjustments
if necessary.
After the knives are confirmed to be properly set,
check to see if the work table is set parallel to the
cutterhead as follows.
Disconnect machine from
power source before making any
adjustments. Failure to comply may cause
serious injury.
1. Disconnect machine from power source.
2. Rotate the cutterhead such that one of the
knives (A) is at the 6 o'clock position.
Figure 24
3. Place a gauge block (B) or another
measuring device on the work table (C) at
one edge (D) directly under the cutterhead.
4. With the handwheel (F), gently raise the
table (C) until the gauge block (B) makes
slight contact with the tip of the knife blade.
5. Move the gauge block (B) to opposite end of
table (E).
If the distance from the table to tip of the knife
blade is the same at both ends, the table is
parallel to the cutterhead.

Adjusting Work Table Parallel to Cutterhead
Refer to Figure 26:
If the work table is not parallel to the cutterhead,
perform the adjustment procedure as follows:
6. Identify which side of the planer table (A) you
intend to adjust: the front or back side.
7. With an 8mm hex wrench, loosen the two
socket head cap screws along the edge the
adjustment is being made: B
1
and B
2
if
adjusting the front of the table, or C
1
and C
2
if
adjusting the back.
8. Bring the table (A) parallel to the cutterhead
by turning both the corresponding lead
screws (D) by hand an equal amount.
Note: Turning the lead screw clockwise will
increase the distance between the table and
cutterhead. Turning the lead screw counter-
clockwise will decrease the distance.
9. Repeat steps 3 - 5 to determine if the planer
table (A) is level with the cutterhead. If further
adjustment is necessary, repeat steps 6 - 8.
When the table is determined to be parallel to the
cutterhead, tighten the
socket head cap screws
(B
