2. Position and align the truck to
obtain as direct a pull as possible.
Straight line pulls are the best and
most efficient.
3. Set the brakes on your Jerr-Dan
unit. The use of scotch blocks is
also recommended.
4. Unfold the under lift boom.
5. Disengage the winch “free-spool”
by pulling out on the “T” handle
and turning the handle 90°. The
handle should remain in the “free-
spool” position.
Never turn this
handle while the wire rope is
under load!
This allows the wire
rope to be pulled directly off the
drum to the work.
