O--rings.
C. Place bushing onto cartridge valve stem. Use a
small amount of grease to keep bushing toward the
top of the valve stem.
B. Carefully push spool down into mow manifold
port until lower O--ring and back--up ring groove is
exposed on bottom of manifold. Install lower O--ring
and back--up ring to spool. Apply a light coating of
grease to O--ring.
D. Place compression spring and detent pin into
handle cap. Use a small amount of grease to hold
detent pin in place.
C. Carefully raise mow/backlap spool until upper re-
