Never turn the handle while
the wire rope is under load.
Maintain a minimum of fi ve (5)
wraps of wire rope/cable on
the winch drum at all times.
Also maintain a uniform wrap
of wire rope/cable on the
drum to avoid crushing of the
wire rope/cable.
5. Unhook the wire rope cables
from the top of the tow sling.
6. Set both boom winches
into “free spool” using the
disengagement levers. Raise,
lift, and pull out on the free-spool
lever handle. Lower the free-
spool lever handle capturing the
lever stop bar on the outside of
the bracket locking the winch
in free-spool. Never pull this
handle while the wire rope is
under load! Moving the boom
head with the wire rope locked
can result in damage to both
the wire ropes and the boom.
Be sure both winches are free
spooling. This allows the wire
rope to be pulled directly off the
drum to the work.
