COUPLING TO THE TOW VEHICLE
WARNING
Incorrect rigging of the safety chains can result in loss of control of the trailer
and tow vehicle, leading to death or serious injury, if the trailer uncouples from
the tow vehicle.
Chains must:
• Fasten to frame of tow vehicle, not to hitch or ball. • Cross underneath hitch
and coupler with minimum slack to permit turning and to hold tongue up, if the
trailer comes loose.
WARNING
Improper electrical connection between the tow vehicle and the trailer will
result in inoperable lights and electric brakes, and can lead to collision.
Before each tow:
• Check that all lights and turn signals work. • Check that the electric brakes
work by operating the brake controller inside the tow vehicle.
ATTACH BREAKAWAY BRAKE LANYARD – BUMPER PULL TRAILERS
If the coupler or hitch fails, a properly connected and working breakaway brake system will apply
the brakes on the trailer. The safety chains will keep the tow vehicle attached and as the brakes
are applied at the trailer’s axles, the trailer/tow vehicle combination will come to a controlled
stop.
• Connect the lanyard to the tow vehicle so that the hydraulic actuator will engage or the electric
brake pull-pin will be pulled out before all of the slack in the safety chains is taken up. Do not
connect the lanyard to a safety chain, hitch ball or hitch ball assembly. This would keep the
breakaway brake system from operating when it is needed.
