NO TOOLS REQUIRED
Full disassembly and reassembly can conveniently be performed without
the need for any tools. To remove the drum, pull back the spring-loaded
release latch and a slight anti-clockwise rotation will allow the self-tailing
arm to be lifted from the winch. From there, the drum can be removed
from the winch centre stem.
When completing reassembly in reverse order, an audible click con昀椀rms
positive engagement between the self-tailing arm and bayonet notches
on the centre stem. These notches allow the self-tailing arm to be locked
in one of 8 positions at rotational increments of 45 degrees.
