-18- G1021 15" Planer
Figure 13 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 of less than 0.016":
1. Determine which side of the table must be
raised to correct the gap.
2. Locate the two cap screws in the table cast-
ing for each of the columns. See Figure 13.
Loosen both sets of cap screws for each col-
umn on the side you wish to adjust.
3. Push down or pull up the table in the desired
direction. Hold the table in position and
retighten the cap screws.
4. Recheck the table to cutterhead parallelism
again. Repeat steps 1 through 7 until the
deviation is less than 0.004".

Knife Inspection
The Model G1021 Planer has a three-knife cut-
terhead. The cutterhead is located in the head
casting and rotates on two sealed bearings. No
lubrication is needed for the life of the bearings.
Because of normal use and wear, the knives
must be periodically sharpened, replaced or
adjusted. Adjustment from the factory must also
be checked prior to use due to possible move-
ment during shipment.
TO INSPECT THE KNIVES:
1. Lower the table and place the gauge block
under one end of the cutterhead.
2. Carefully turn the cutterhead until the first
knife is at bottom dead center. Raise the table
until the knife barely touches the top of the
gauge block. Rock the cutterhead over the
gauge block as you raise or lower the table to
determine bottom dead center.
3. Slide the gauge block to the opposite side of
the cutterhead and check the same knife,
rocking back and forth to determine bottom
dead center. If the knife does not contact the
gauge block, use a feeler gauge to determine
the difference between one side and the
other. See Figure 14. Again, rock the cutter-
head back and forth over the gauge block and
feeler gauge.
WARNING
Planer knives are dangerously sharp. Use
extreme caution when inspecting, remov-
ing, sharpening, or replacing knives into the
cutterhead. Substantial risk of injury!
