Attach the white wire with the grounding ring to the trail- •
er frame with the 1/4” self-drilling screw supplied. This is
the connecting ground wire for the trailer lights only.
Route the molded mating plugs through the hole in the •
tongue cap.
Snap the mating plugs from the wire harness to the respective •
mating plugs from both the SD control box and the actuator ac-
cording to the instructions provided with the electric over hydrau-
lic kit. See the wiring schematic on page 20 of the manual pro-
vided with the actuator. Make sure they are completely snapped
together and locked to assure a positive connection.
The breakaway switch is already attached and wired into •
the main wire harness. Locate the breakaway switch.
Route the tongue harness around the side of the tongue •
so the breakaway switch can be mounted on the top of the
tongue.
Position it so it is approximately 3” behind the rear of the •
coupler. Mark the mounting hole location. Drill a 13/64” pilot
hole in the tongue. Insert the 1/4” self-tapping screw provided
and secure in place.
Fill the actuator with the appropriate brake fluid as specified in the •
brake manual supplied. Bleed the system per their instructions.
Assembly is complete. •
ALL MODELS
Filling the System with Brake Fluid
All Kits
Fill the reservoir on the actuator with an Arctic-SAEJ1702 or
SAEJ1703 brake fluid or a fluid that is comparable. Remove one
of the reservoir caps located on the actuator unit as identified in
Diagram A. Only one cap has to be removed. Add fluid until the
reservoir is full. Bleed the brake system following the procedure for
bleeding the brakes. If complete bleeding of the system is required,
it may be necessary to add fluid to the reservoir during the bleed-
ing process. Once the system is completely bled, refill the reservoir
until full. Replace the cap and tighten to seal our any moisture that
may enter during normal use.
Bleeding the Brake System
All Kits
Partial Bleeding of the Hydraulic Brake System
If the electric over hydraulic system is being added to a current
brake system that is already installed and has been in use it is pos-
sible that you only need to bleed the air out of the system where the
connections were made in the lines to connect the new actuator
system. The procedure is as follows:
1. Check to make sure brake fluid has been added to the system
as recommended above.
2. Pull the cable on the breakaway switch installed just behind
the coupler. This will pull a pin out the switch automatically
activating the switch. The actuator will now draw its power from
the batteries installed on the trailer. The actuator will continue
to run until the batteries are drained. You will be able to hear
the actuator motor run.
3. With the actuator running, loosen the bleeder screw on the
right brake caliper. The actuator will continuously pump brake
fluid in the system removing all of the air in the line from the
actuator to the right caliper.
4. When all air is removed, close the bleeder screw. Push the pin
back into the breakaway switch. This will stop the electrical
supply to the motor stopping it from running.
5. Refill the reservoir with fluid replacing any that may have been
used during the bleeding process. Test the brake system to
see if it is bled properly. If brakes function properly the bleeding
process is complete. If they do not operate properly, repeat the
above steps and test again.
6. Brake fluid levels in the reservoir should be checked occasion-
ally to make sure your brake system never runs out of brake
fluid.
Complete Bleeding of the Hydraulic Brake System
If a new system that has never been used or bled before it then
requires that the complete system be bled. The procedure is as
follows:
1. Check to make sure brake fluid has been added to the system
as recommended above.
2. Pull the cable on the breakaway switch installed just behind the
coupler. This will pull a pin out the switch automatically activat-
ing the switch. The actuator will now draw its power from the
batteries installed on the trailer. The actuator will continue to
run until the batteries are drained. You will be able to hear the
actuator motor run.
3. The proper procedure for bleeding the brake system is to start
at the caliper that is the greatest distance from the actuator.
This would be the left caliper on the axle or the left caliper on
the 2nd axle should your trailer have dual axle brakes. Loosen
the bleeder screw and allow the air to escape from the system
until brake fluid starts to flow. Allow it to flow until the brake
fluid being expelled is free of any air bubbles entrapped in the
lines. Attaching a clear hose on the bleeder screw will make the
air bubbles more visible during the bleeding process. Close the
bleeder screw and tighten.
4. Check the reservoir fluid level to make sure that the actuator
does not run low on fluid during the bleeding process. Refill if
necessary. There is a possibility that more air can be introduced
into the system if the fluid level is not kept sufficient in the reser-
voir.
5. Repeat the process used in step three on the caliper that is
located the next greatest distance from the actuator. Continue
until all of the brake calipers have been bled.
6. Once the system is bled, When all air is removed, close the
bleeder screw. Push the pin back into the breakaway switch.
This will stop the electrical supply to the motor stopping it from
running.
7. Refill the reservoir with fluid replacing any that may have been
used during the bleeding process.
