LS600 PUMP — TRAILER SAFETY GUIDELINES
Breakaway Brake System
If the coupler or hitch fails, a properly connected and
working breakaway brake system (Figure 55) will apply the
hydraulic 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.

Figure 55. Breakaway Brake System
Breakaway Cable Surge Brake System
The breakaway brake system includes a brake cable
connected to the tow vehicle on one end and to the
emergency brake lever located on the hydraulic actuator
on the other end.
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 uncouples,
the safety chains can hold the tongue up above the
road.

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.
WARNING - Safety Chains Rigging
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.
WARNING - Brakeaway Cable
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
manufacturer.
