The tray is attached to and removed from
the frame by sliding the square metal tube into
the top of the main spine. Before you insert the
tube unlock the locking lever (a), insert the tube
and relock the lever.
To lock the tray and set its height push the
locking lever (a) down until it touches the metal
spine. After use the locking lever needs to be
fine tuned to ensure secure locking. To do this
lift up the lever and turn the nut (b) while holding
the lever in a fixed position. Push the lever back
down to check if it locks the tube securely.
Repeat the process as necessary.
Always use caution when making this
adjustment, as fingers could become
trapped in the receiving tube while
positioning.
