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.

Adjusting the height of the top surface

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.
