Loosen handle knobs and lift top handle half in an arc until handle halves are in line and nest together (Fig. 2). Note: 2. Use care to prevent pinching or stretching of cables. Tighten knobs securely. Note: Belt cover may need to be loosened and slightly moved out of the way to make enough room to place handle in high height setting. Adjust self–propelled cable. See Maintenance section.
2. Remove screw that fastens cover plate to the housing (Fig. 5). 3. Two shoulder bolts on the housing protrude through slotted holes in the cover plate and do not have to be loosened or removed.
