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
NOTE: 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 (see
figure 18) in the side of the enclosure with a long Phillips-
head screwdriver, you should not need to remove the HSA 
from the table.
