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
that came with the jack you are replacing for in‐
stalling the Phoenix 4000 Electric Tongue Jack.
1. Install the Electric Tongue Jack using original
nuts and bolts. Depending on user's personal
preference, align the motor head so that the
motor housing is facing the front of the "A"
frame or so that the motor housing is facing the
driver side of the trailer.
2. The Electric Tongue Jack was designed to re‐
place an existing manual 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.
3. Install Fuse Holder. By cutting the RED wire
loop, then either crimping or soldering the con‐
nections, attach one end to the positive post of
the trailer battery. The other end of the fuse
holder's RED wire will be connected to the RED
wire from the jack. This RED wire provides 12V
power to jack.
4. Connect the RED positive lead to the positive
terminal of the battery. Connect the BLACK
ground wire to negative terminal of the battery.
WARNING
tension wire, DO NOT use smaller
than #10 gauge wire.
CAUTION
mend using the flip‐up type footpad.
Doing so requires the tongue jack to
be altered which voids the warranty and can
cause the failure of the jack.
