Breakaway Switch & D.O.T. Wet Cell
Battery
After hitching to the tow vehicle, pull the safety pin
on the breakaway switch. Check to see if system is
operational. Push safety pin back in to its original
position.
Check battery fluid level every 60-90 days. Remove
cover. There are two fill caps. Refill with distilled
water only.
Breakaway Switch Mounted on an A-
Frame
Attach breakaway switch cable securely in a
straight line to the tow vehicle. Locate attachments
so little “slack” is left in the cable, but enough slack
to allow for turning without disengaging the pin.
The cable will activate brakes the instant a trailer
becomes disengaged. Brake adjustment is critical
to stopping a disengaged trailer.
Check Breakaway System & Brakes Before
Each Trip
1.

4.
Replace pin and secure to tow vehicle. Do not loop
over hitch ball.
5.

Brakes
Your trailer is equipped with electric brakes.
Complete service and repair information for the
electric brakes is found in the Axle Break Service
Manual that is furnished with your trailer,
Note: It is important to strictly adhere to the axle break
instructions for brake service and repair. In this way,
you are protecting the validity of all applicable warran-
ties
.
Burnishing the Brakes
Brakes on a new trailer may tend to “grab” or pulsate.
This is normal. To correct the situation, pull the trailer
with the trailer brake control slightly engaged a short
distance (about 1000 ft or until trailer does not grab or
pull to one side anymore). This action smooths down
the brake bands
.
NOTE: Do not lock up the wheels.
