mooring lines. After adjustment, a lag with proper setting values should be aI/ached to the
winch. On spring-applied bra kes, the spring adjustment mechanism should be secured with a
seal 10 prevent inadvertent tampering. - Mooring lines must be spooled onto the drum in the correct direction, since band brakes are
designed to work in one direction only. - Winches that are provided with both a drum brake and an input brake should be operated
with one brake only while the ship is moored. On multiple drum winches, tltis will always be
the drum brake. On single drum winches, the instruction book should be consulted to determine
which brake is the primary brake designed 10 hold 601110 of the line's MBL. Where the drum
brake is the primary brake, the dutch between drum and shaft should be disengaged while the
