DANGER: Tongue weight beyond rating limits will interfere with performance of
actuator, and braking system, and the tow vehicle.
9. The actuator is designed for use with Free-Backing trailer brakes. To block
braking action, (in order to back up) with other types of brakes including disc
brakes, use an electric solenoid. For trailer movement when brakes are not required,
place the safety pin in the hole on the side of the actuator housing to block
movement of the actuator.
DANGER: Failure to remove pin will also prevent forward braking. Pin must
be in the lower, forward hole as a safety lock for the hitch ball coupler latch
when towing at all times.
Directions Vehicle Wiring - Brake Solenoid
1. Disconnect trailer hitch and any wiring connectors from the vehicle.
2. Connect a 14 gauge wire to the backup (reverse) light wire of the vehicle. This
wire should be of sufficient length to attach to the existing vehicle/trailer
wire receptacle. The end of this wire will require a female end that will match the
solenoid male connector wire. Your vehicle may have a 5 wire connection for
this purpose.
3. For ease of use, tape or band the end of the reverse light wire to the vehicle’s
trailer electrical connector.
Maintenance
1. Always check the brake fluid reservoir before using trailer. Make sure it is at least
half full. If not, re-fill to 3/8 inch below the top of the reservoir with DOT 3 brake
fluid. Do not use DOT 5 brake fluid. Check for leaks and repair as required.
Never reuse brake fluid.
2. To extend coupler and ball life, coat both with a thin coating of grease. This will also
eliminate squeaking. Wipe clean and renew film each time trailer is used.
3. Examine the actuator for bent parts or wear each time the trailer is used.
Replace parts as necessary.
4. There are no user adjustments on the actuator.
5. Actuator travel (shown by coupler roller path) over one inch indicates a need to
adjust the brakes or add fluid to the reservoir or a need to bleed the brakes and
check connections for leaks. Adjust per instructions found in brake installation
manual. In general, back-off adjusters on drum brakes from locked position, as
required. Adjust Free-Backing brakes by rotating in forward direction only. Failure
to adjust may result in loss of braking. Disc brakes do not require adjustment,
check for pad wear.
