REEL IN Position. The sequence of operation for REEL IN is identical to that for REEL OUT. The only difference is in
control lever throw, which results in spool (16) being moved into valve body (6). Chamber (25) fills instead of chamber
(24). Chamber (25) is connected to the left directional clutch and winch drum rotation will reverse.
