6.
BRAKE OFF Position. In this position, the winch drum is free to rotate in either direction because both directional
clutches will be disengaged. The input clutch will also be disengaged. When in BRAKE OFF position, spool (16) is cen-
tered in valve body (6), connecting both chambers (24 and 25) to oil passage (15). The outlet from chamber (22) to the
input clutch is blocked by spool (16). Coupling (11) is moved into valve body (2) in the same manner as described for
REEL OUT operation. The shifting of spools (8 and 14) and the function of sequence valve (17) is also the same oil pas-
sage (15) and chambers (24 and 25) will remain pressurized, keeping both directional clutches disengaged, until the con-
trol lever is returned to the HOLD position.
