Suggestions for Safe Operation
DO the following:
Read and comply with the guidelines set forth in this Owner’s Manual. Keep
this manual, and all labels attached to the winch, readable and with the
equipment at all times. Contact Thern, Inc. for replacements.
Before each use inspect the winch for leaks or other damage.
Install the rope securely to the winch drum.
Install the winch in a well-lit area, free of clutter and trip hazards. It should
be positioned where there is a good line of sight of the winch, rigging and load
being moved. Use a spotter if load path is obstructed. The mounting should
take into consideration the ergonomics of handling the rope as well as operat-
ing the rope lock.
Use the proper amount of rope wraps on the drum to keep the hand effort to
about 20 pounds of pull. This will vary based on the load being moved, rope
size, and rope construction. See section 1.3 for additional information.
Keep hands away from the pinch points between the drum and the rope, and
other moving parts of the equipment.
Wear hearing protection when operating the winch.
Keep all unnecessary personnel away from winch while in operation. Keep
out of the path of the load.
Disconnect electric power before servicing the equipment.
Stay out of path of potential spring back of broken rope.
Position the winch such that the load line fleet angle is minimized. See section
1.1 for additional information.
Secure the rotation stop used with the swivel mount, when supplied, before
operation to prevent unexpected rotation. Properly align winch with load to
prevent rotation or damage to rotation stop.
Before operation with the swivel mount, when supplied, verify the pivot bolt
and nut are secure with safety cotter pin properly in place.
Ensure mounting surface or vehicle is rated for expected loads, including
potential shock loads.
Use only Thern manufactured accessori
es with the Thern 3CP1 and 3CP2
series capstan winches. Use of non-Thern accessories may result in injury,
poor performance, and loss of warranty.
