NOTE:

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
1.
Block the wheels and support the trailer "A" frame securely.
2.
Remove the existing jack.
NOTE: Save the original nuts, bolts, and washers for installing
the Electric Tongue Jack.
3.
Install the Electric Tongue Jack using original nuts and bolts.
4.
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.
5.
Align the motor head so that the motor housing is facing the
front of the "A" frame.
6.
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.
OPERATION
1.
Block trailer wheels securely.
2.
The Electric Tongue Jack is operated by means of the Toggle
Switch located under the motor housing.
3.
Extend the jack by holding the Toggle Switch in the Extend
position.
4.
Retract the jack by holding the Toggle Switch in the Retract posi-
tion. 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 re-
tracted position, and the Toggle Switch Is not released, the motor
will automatically switch off.

dle tang. Rotate the crank handle clockwise to retract and counter

and reassemble the fuse connection.
LUBRICATION
The jack is lubricated before leaving the factory. Under
normal conditions, lubrication will be needed after one year.

Using the Toggle Switch, extend the jack until the Foot Pad is 2"
from the ground.

Loosen the four #8 Phillips Head Screws and remove the Gear
Housing Cover.

If required, repack the exposed gears with a common Lithium
Base Machine Grease.
