G0550/G0551 15" Planer -29-
It is important that the cutterhead is parallel to the
table to plane stock perfectly square.
To check the table alignment:
1. Disconnect the machine from the power
source!
2. Place the gauge block on the table under
one end of the cutterhead
.
3. Turn the handwheel to raise the table until
the block barely touches the cutterhead
body.
The block should not be touching
the knives. See Figure 28.
4. Slide the block toward the opposite side of
the cutterhead. Use a feeler gauge to mea-
sure the width of the gap, if any, between the
top of the block and the bottom of the cutter-
head. If there is a gap, make a note, reading
the distance from the feeler gauge.
5. If the block wedges tightly between the table
and cutterhead when shifting from one side
to the other, repeat
steps 1 through 3 above,
but start from the opposite end of the cutter-
head.

— If the gap difference from one side to the
other is equal to or less than 0.004", no
further adjustment is necessary.
Figure 29. Cap screws for column adjustment.
— If the gap difference from one side to the
other is greater than 0.004", but less than
0.016", go to
step 5.
If the gap difference from one side to the other is
greater than 0.016", the table raising chain under
the planer base will need to be adjusted. Please
call our Customer Service number for chain
adjustment instructions.
To adjust for gap differences:
6. Determine which side of the table must be
raised to correct the gap.
7. Locate the two cap screws in the table cast-
ing for each of the columns.
See Figure 29.
Loosen both sets of cap screws for each col-
umn on the side you wish to adjust.
8. Push down or pull up the table in the desired
direction. Hold the table in position and
retighten the cap screws.
9. Recheck the table to cutterhead parallelism
again. Repeat
steps 1- 8 until the deviation
is less than 0.004".
