Insert the upper frame into the lower frame. Make sure
the U shape of the silver round tube is pointing toward
the front of the lower frame. Insert the silver vertical
square tube over the black round gas spring. Refer to
Figure 10. Continue to slide the upper frame down and
into the square tube of the lower frame. Fixed inside the
larger square tube of the lower frame are plastic inserts.
These pieces fit snugly between the two square tubes. If
the silver square tube does not immediately slide past the
plastic inserts, put slight pressure on the silver square tube
to help align it in place. When aligned properly, the upper
frame should easily slide down into the lower frame.
Forcing the upper frame into the lower frame when not
properly aligned can cause damage to the plastic inserts.
