• Totestthebreakawaybattery,removethepull
pin from the switch and attempt to pull the trailer

ing towed, but the wheels will not necessarily be
locked. If the brakes do not function, do not tow
the trailer until brakes, or battery, are repaired.
• Immediatelyreplacethepullpin.Thebreakaway
system battery discharges rapidly when the pull
pin is removed.
WARNING
An ineffective breakaway system can result
in a runaway trailer, leading to death or
serious injury if the coupler or ball hitch fails.
Test the function of the breakaway system
before towing the trailer. Do not tow the
trailer if the breakaway system is not
working;haveitservicedorrepaired.
Connect the breakaway lanyard to the tow
vehicle–NOTtothesafetychain;and
NOT to the hitch, ball or support.
Do not tow the trailer with the breakaway system ON
because the brakes will overheat which can result in
permanent brake failure.
WARNING
Failure to replace the pull pin can result in
ineffective brakes, leading to loss of control,
serious injury or death.
If you do not use your trailer for three or more
months, or during winter months:
• Storethebatteryindoors;and

If your trailer has electric brakes, your tow vehicle will
have to 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 m.p.h., manually operate the electric
brake controller in the tow vehicle cab. You should
feel the operation of the trailer brakes.
WARNING
Failure to connect the tow vehicle lighting
and braking to the trailer will result in
inoperable lights and brakes, and can lead
to collision.
Check that all the trailer lights and brakes
work before each tow.

tow vehicle:
• Blocktrailertirestopreventthetrailerfromroll-
ing, before jacking the trailer up.

Trailer with Fifth Wheel Pin Box and Drop-Leg
Jacks
A fifth wheel pin box on the trailer connects to a fifth
wheel hitch that is installed on the tow vehicle.
Lance Trailer has selected a fifth wheel pin box that is
suitable for the size and weight of the trailer. You must
provide a fifth wheel hitch that matches the pin box,
and that is rated for the Gross Vehicle Weight Rating
(GVWR) of your trailer.
