HOW TO USE YOUR ELECTRIC BRAKES PROPERLY
Your trailer brakes are designed to work in synchronization with your tow
vehicle brakes. Never use your tow vehicle or trailer brakes alone to stop the
combined load.
Your trailer and tow vehicle will seldom have the right amperage flow to the
brake magnets to give you comfortable, safe braking unless you make proper
brake system adjustments. Changing trailer load and driving conditions as well
as uneven alternator and battery output can mean unstable current flow to your
brake magnets. It is therefore imperative that you maintain and adjust your
brakes as set forth in this manual, use a properly modulated brake controller,
and perform the synchronization procedure noted below
In addition to the synchronization adjustment detailed below, electric brake
controllers provide a modulation function that varies the current to the electric
brakes with the pressure on the brake pedal. It is important that your brake
controller provide approximately 2 volts to the braking system when the brake
pedal is first depressed and gradually increase the voltage to 12 volts as brake
pedal pressure is increased. If the controller “jumps” immediately to a high
voltage output, even during a gradual stop, then the electric brakes will always
be fully energized and will result in harsh brakes and potential brake lockup.
Proper synchronization of tow vehicle to trailer braking can only be accom-
plished by road testing. Brake “lockup, grabbiness, or harshness” is quite often
lack of synchronization between the tow vehicle and the trailer being towed,
too high of a threshold voltage (over 2 volts), or under adjusted brakes.
WARNING
:
The braking system should be checked and serviced
by qualified, certified technicians only. Failure to do so could result in loss
of control of your vehicle or the trailer causing damage to property, injury,
and/or death.
POWER JACK
A switch located on the bottom of the housing operates the power jack. When
the jack is fully extended or retracted internal limit switches automatically shut
off the motor.
Should an electrical failure occur, remove the power head by loosening the two
Allen set screws. The jack post may now be operated manually by inserting the
emergency handle into the coupling on top of the post.
The jack is wired directly to the battery and has an inline fuse between the
battery and the power head.
