Managing Waste
PACCAR Winch believes in a life-cycle approach to our products. We encourage best practices regarding “Going
Green” — making environmentally responsible decisions to “reduce, reuse, and recycle.”
• At the end of the winch’s useful life, it is highly recommended to drain and recycle any oil remaining in the equipment.
•
Please use a metal recycler for winch disposal to reduce landfill waste.
The U.S. Environmental Protection Agency has developed required practices, called “management standards,” for busi-
nesses that handle used oil and metal wastes. Specific guidelines are available at the EPA and API websites as well as
your state’s environmental agency website:
• https://www.epa.gov/
• http://recycleoil.org/

The following service manual has been prepared to provide maintenance information for the BRADEN TR20A recovery
winch.
Some illustrations in this manual may show details or attachments different from your winch. Some components have
been removed for illustrative purposes. Drawings in this manual represent a typical unit sold through our distribution
channels. Some winches, particularly those sold directly to original equipment manufacturers, may differ in appearance
and options.
