Pull Knobs
Pull knobs are found on the lower frame. Behind the
round knob is an X shaped slot. These slots act as a
guide for a retaining pin attached to the pull knob. Pull the
round black knob out so the retaining pin is free. Rotate
the knob 90 degrees so the retaining pin lines up with other
slot. Release the knob and allow the retaining pin to slide
into the slot. The pull knob is in the locked position
when the retaining pin is in the deeper of the two X slots.
Refer to Figure 3.
