 Maintain adequate vertical down (tongue) load to have control of the trailer (generally 10%), but
not exceed the specified rated capacities.
 Other steps and inspections are also required Consult OSHA, D.O.T. regulations and American
Trucking Association for complete coupling and uncoupling procedures.
 Check that ball load rating is same as or greater than coupler load rating.
 ALWAYS use safety chains.
 DO NOT use top holes for mounting.
Towing
⚠WARNING
 Only use trailers and equipment designed for on-road towing within the stated capacities.
Installation Instruction
⚠WARNING
 Use a secure mounting structure of sufficient strength to support the rated capacity of the coupler
in accordance with SAE J684.
 Bolt the coupler to the front of the trailer tongue, bolting through the coupler’s side holes. Use 3/8"
diameter grade fasteners (8), properly tightened (not included).
 Additional bolts may be used in top holes for extra strength, if desired.
 The recommended minimum torque is 37 ft-lbs, (per SAE J429).
