Grizzly G1021 instruction manual Knife Inspection, To Inspect the Knives

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".

Loosen these cap screws to micro adjust the table height

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!
