Adjusting the Top Surface

The top lifting panel of the HSA 822 can be adjusted to raise or lower its level flush with the flange. It can also be adjusted to ensure that the lifting panel is horizontal and not tipped.

You may be able to adjust the height of the top lifting panel without removing the HSA 822 from the table. If you can reach the height adjustment lock screw slots (figure 3-7) in the side of the enclosure with a long Phillips-head screwdriver, you should not need to remove the HSA from the table.

Raise or lower the lifting panel flush with the flange as follows:

	slots in the side of the HSA enclosure, remove the surface
	mount enclosure from the table. See “Removing and
	Replacing the Enclosure”, steps 1 through 9. Place the
	enclosure on its side on a horizontal surface. To protect
	the finish, place the enclosure on a soft cloth.
2.	If necessary, close and latch the top panel.
3.	Slightly loosen the two locking screws (figure 3-8).
