2)Adjust Action of Movable Arm
The action of the movable arm can be adjusted depending on how
much weight is placed on the tray.
Adjust it in the following way:
a)For a heavy load (or to make the up and down action stiffer)
Tighten the movable arm’s knob to make its action stiffer and keep it
from sagging up a heavy load.
Tightening this knob completely will lock the arm in place and keep
it from moving up and down.
b)For light loads (or to make its action looser)
Loosen up the knob for freer tray action.
Keep a grip on the handle when loosening the
knob. Otherwise, the tray could suddenly spring
up if it was being held in a low position.
