SECTION 2 - TRAILER OPERATION
2-10 – Triple-L-Trailer – 3121224
TO AVOID POSSIBLE INJURY DO NOT TOW THE TRAILER WITH
THE PULLPIN REMOVED AND THE BREAKAWAY BRAKE SYSTEM
ON BECAUSE THE BRAKES WILL OVERHEAT WHICH CAN
RESULT IN PERMANENT BRAKE FAILURE.
If you do not use your trailer for three or more months, or
during winter months:
a. Store the battery indoors
b. Charge the battery every three months.
Replace the breakaway brake battery according to the
intervals specified by the battery manufacturer.
Attach and Test Hydraulic Breakaway Brake
System
If the coupler or hitch fails, a properly connected and
working breakaway brake system will apply the hydraulic
(surge) 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 cable attached to
an activation lever. Read and follow the instructions here
as well as the instructions that have been prepared by the
breakaway brake controller manufacturer.
Connect the breakaway cable to the tow vehicle so that
the activation lever will be pulled before all of the slack in
the safety chains is taken up. Do not connect the break-
away cable to a safety chain or to the hitch ball or hitch
ball assembly. This would keep the breakaway brake sys-
tem from operating when it is needed.
Manually pull the activation lever and test tow the trailer, at
less than 5 m.p.h. You should feel the trailer resisting
being towed, but the wheels will not necessarily be
locked. If the brakes do not function, do not tow the trailer
until the brakes are repaired.
Reset the activation lever prior to towing.
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.
NOTE: Do not tow the trailer with the breakaway brake sys-
tem ON because the brakes will overheat which can
result in permanent brake failure.
Connect the Electrical Cables
Connect the trailer lights to the tow vehicle's electrical sys-
tem using the electrical connectors.
Check all lights for proper operation:
a. Clearance and Running Lights (Turn on tow
vehicle headlights).
b. Brake Lights (Step on tow vehicle brake pedal).
c. Turn Signals (Operate tow vehicle directional
signal lever).
d. Backup Lights (Put tow vehicle gear shift into
reverse).
Check electric brakes for proper operation.
If your trailer has electric brakes, your tow vehicle must
have an electric brake controller that sends power to the
trailer brakes. Before towing the trailer on the road, you
must operate the brake controller while trying to pull the
trailer in order to confirm that the electric brakes operate.
While towing the trailer at less than 5 mph, manually oper-
ate the electric brake controller in the tow vehicle cab. You
should feel the operation of the trailer brakes.
BEFORE EACH TOW CHECK THAT THE TAILLIGHTS, BRAKE
LIGHTS AND TURN SIGNALS WORK. CHECK THAT THE ELEC-
TRIC BRAKES WORK BY OPERATING THE BRAKE CONTROLLER
INSIDE THE TOW VEHICLE.
Uncoupling the Ball Hitch Trailer with
Tongue Jack
Follow these steps to uncouple your ball hitch trailer from
the tow vehicle:
1. Block or chock trailer tires to prevent the trailer from
rolling, before jacking the trailer up.
2. Disconnect the electrical connector.
3. Disconnect the breakaway brake switch cable. For
an electric breakaway break system, promptly
replace the pullpin in the switchbox.
4. Disconnect the safety chains from the tow vehicle.
5. Unlock the coupler and open it.
6. Before extending the tongue jack, make certain the
ground surface below the jack pad will support the
tongue load.
7. Rotate the jack handle (or crank) clockwise. This will
slowly extend the tongue jack and transfer the
weight of the trailer tongue to the jack.
