NOTE
Many OEM truck trailer connectors do not have the AUXILIARY POWER/BATTERY CHARGE terminal connected from the factory.
If the jack does not work when connected, it may be necessary to contact your truck dealer for instructions on enabling the circuit or checking the appropriate fuse or breaker.
If your jack fails to function, use a test light between the terminals shown below to determine if you have power at the appropriate terminals.
INSTALLATION
- Block the wheels and support the trailer “A” frame securely.
- Remove the existing jack.
NOTE: Save the original nuts, bolts, and washers for installing the Electric Tongue Jack. - Install the Electric Tongue Jack using original nuts and bolts.
- The Electric Tongue Jack was designed to replace an existing crank down jack. The diameter of the outer tube of your chosen jack, will need to match the existing hole size, or you will need to modify the hole diameter to fit.
- Align the motor head so that the motor housing is facing the front of the “A” frame.
- Connect 7-pin trailer connector to vehicle’s trailer plug, or, if hard wiring connect the black positive lead to the positive terminal of the battery. The Electric Tongue Jack is internally grounded, and needs no ground wire if “A” frame is properly grounded.
WARNING
When using an extension wire, DO NOT use smaller than #10 gauge wire.
OPERATION
- Block trailer wheels securely.
- The Electric Tongue Jack is operated by means of the Toggle Switch located under the motor housing.
- Extend the jack by holding the Toggle Switch in the Extend position.
CAUTION
Release the Toggle Switch when the motor switches off to prevent damage to motor and #14 Headed Pin. Wait 15 seconds for the motor to reset before operating the jack again. - Retract the jack by holding the Toggle Switch in the Retract position. As the jack approaches the fully retracted position it will slow down and then stall. The Toggle Switch should be released at the first indication of slowing down. The jack is now fully retracted.
NOTE: If the motor should stall with the jack in the fully retracted position, and the Toggle Switch Is not released, the motor will automatically switch off.
