Table Calibration - Grizzly G0677 Owner's Manual

Table Calibration

The digital thickness gauge is calibrated at the
factory, but we recommend you verify its accu-
racy. This can be done by feeding a test board
through the machine and measuring it in many
locations on both sides along the length, then
calibrating the digital display to match the average
measured thickness of the workpiece.

1.
Run the test board though the planer/sander
three to four times to plane and sand it.
2. Turn the board over, and repeat Step 2.
3.
Measure the thickness at various points
around the board using a set of calipers.
4.
Without moving the table height, enter the
numerical measurement from
digital key pad on the control panel.
Note: The average thickness of the sanded
wood should now be flashing on the digital
read-out.
5. Press and hold the Set key
play stops flashing. The machine is now cor-
rectly calibrated.

Table Limit Switches
The table limit switches prevent the table lift motor
from driving the table into the sanding drum.
Periodically check and adjust (if required) the
table stop switches to protect the feed belt.

—If the table lift motor does not shut OFF
when the table reaches the minimum and
maximum distances from the sanding drum,
the limit switches need to be adjusted.
Proceed to Step 4.
Push the down arrow key

sanding drum and the feed belt table sur-
face.
Loosen the mounting bolts for the table-down
limit switch and slide the switch so the switch
plunger depresses against the stop block and
you hear the switch click (see Figure 47).
