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.
