 Visually inspect the safety chains and hooks for wear
or damage. Replace worn or damaged safety chains
and hooks before towing.
 Attach the safety chains so that they:
A. Cross underneath the coupler. See Figure 54.
B. Loop around a frame member of the tow vehicle
or holes provided in the hitch system (DO NOT
attach them to an interchangeable part of the hitch
assembly).
C. Have enough slack to permit tight turns, but not
be close to the road surface, so if the trailer un
couples, the safety chains can hold the tongue
up above the road.

WARNING Safety Chains Rigging
Improper 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.
• Fasten chains to frame of tow vehicle. DO NOT fasten
chains to any part of the hitch unless the hitch has
holes or loops specifically for that purpose.
• Cross chains underneath hitch and coupler with
enough slack to permit turning and to hold tongue up,
if the trailer comes loose.

Breakaway Brake System
If the coupler or hitch fails, a properly connected and work-
ing breakaway brake system (Figure 55) will apply the hy-
draulic 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.

The breakaway brake system includes a brake cable con-

WARNING Brakeaway Cable
An ineffective breakaway brake system can result in a
runaway trailer, leading to death or serious injury, if the
coupler or ball hitch fails.
Connect the breakaway cable to the tow vehicle; and NOT
to the hitch, ball or support.
Before towing the trailer, test the function of the breakaway
brake system. If the breakaway brake system is not
working, DO NOT tow the trailer. Have it serviced or
repaired.
DO NOT tow the trailer with the breakaway
brake system ON because the brakes will
overheat which can result in permanent
brake failure.
Replace the breakaway brake battery (if
equipped) at intervals specified by manu-
facturer.
