Adjusting the top surface level

The top lifting panel of the HSA 822 can be adjusted to ensure that the lifting panel is horizontal and not tipped. Level the lifting panel of the HSA 822 as follows:

1.	Remove the surface mount enclosure from the table. See
	“Removing and Replacing the Enclosure”, steps 1 through
	9. Place the enclosure 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 six locking screws (figure 3-9) that
	secure the top panel to the panel bracket.
