OPERATION GUIDELINES
ELECTROCUTION HAZARD
SYNTHETIC ROPE - The dielectric properties of a synthetic rope are obtained from a new, clean rope.
These properties hold true only under ideal conditions. Dirt, grease, moisture, humidity, and other foreign
matter will dramatically increase the conductivity of synthetic rope.
WIRE ROPE - Wire rope is 100 percent conductive.
STRINGING THE WINCH LINE
Properly attach the winch line to the drum with attachments furnished. See maintenance manual for proper
attachments.
The first layer (wrap) around the winch drum must be put on closely and tightly. The initial winding (load)
should be approximately 50 pounds (23 kg). This prevents subsequent wraps from sliding down between
turns when tension is applied.
A down haul weight and hook with a latch should be attached to the free end of the winch line. This allows
the winch line to drop easily the ground.
DOWN HAUL WEIGHT
When winding the winch line onto the drum with no load, make sure it is wound level.
Trapped loops can damage the winch line or cause a load to drop on the next winch pay out operation
causing a shock load.
WINCH DRUMS WITH TRAPPED LOOPS
Electrocution Hazard exists when any winch line contacts energized source.
Serious injury or death can result if electrical contact is made with a contaminated
synthetic rope or a wire rope.
This type of contact can electrically charge the rope, the load, and the vehicle.
All winch line hooks used shall be equipped with a latch. Using a hook without a
latch can cause serious injury or death.
Always keep the winch line wound level and tight on the boom winch drum.
