TOWING AND
LONG-TERM STORAGE
TOWING
Failure to follow these instructions exactly can cause hitch ball failure or loss of trailer
attachment resulting in a vehicle crash and/or personal injury.
Use the hitch ball only for towing trailers or vehicles connected to the ball with a socket-type
coupler. The ball diameter must match the coupler socket size. Do not exceed the gross
trailer weight shown on the ball.
Improper tightening can cause hitch ball failure or loss of trailer attachment.
• The threaded shank must protrude beyond the bottom of nut when tightened. If it does
not, the ball shank is too short for the application and loss of attachment may occur.
• Check the nut tightness every time you hook up the trailer and at the beginning of each
towing day. Tow only if the nut is tightened as specied.
• Replace any damaged or worn parts (except nish).
• Never attach a tow rope, chain, or stretch type elastic rope to the hitch ball.
• Do not fasten the trailer safety chain or any other type of attachment to or with, the ball.
• Lubricate the ball and coupler to minimize wear and friction. The coupler must not bind on
the ball.
This product complies with V.E.S.C. Regulation V-5, C.S.A. Standard D-264 and the Safety
Specications and Requirements for Connection Devices and Towing Systems.
