1. Park the trailer on a level surface and chock the
wheels.
2. Support the trailer tongue by the frame with jack
stands.
3. If replacing an old jack, remove the old jack from
the coupler.
4. Insert the Husky®Brute into the jack hole and align
the bolt holes so the motor housing is facing forward as
shown in (Figure 1).
5. Secure the jack with three (3) Grade 5, 3/8”-16 UNC
bolts and washers supplied with the jack. Place the star
washers between the flat washers and the mounting
plate as shown in (Figure 2). The star washers are
intended to penetrate through the paint on the mounting
plate to ensure direct metal to metal contact. Bolts
should be tightened to 15-20 lb-ft.
6. If a lower support plate is not already present,
install one in the bottom of the trailer frame. Do not
operate the jack without a lower support plate. Shown
in (Figure 6).
7. Install the manual reset circuit breaker by either
crimping or soldering the wire from the jack to the
terminal marked “Load” on the breaker. Connect the
“Line” terminal of the breaker to the positive terminal
of the battery. The breaker should be located as close
to the battery as possible and stored inside the battery
box. Since the jack is internally grounded, a ground wire
is not necessary. If mounting the jack to an aluminum
frame trailer, install a ground wire from a jack mounting
bolt to the negative terminal of the trailer battery.
WARNING: When using an extension wire, DO NOT
use a wire smaller than #10 gauge. Figure 2

OPERATION
1. Park your trailer on a level surface and chock all
trailer wheels.
Tip: For nighttime hookups, flip the light switch ON to
illuminate your work area.
2. Before operating the jack, attach the foot with the
3/8” safety lock pin provided.
3. Extend the jack by pushing the operating switch UP.
(With the HB4500R, you can press the UP button on
the remote control – see page 4 for remote control
instructions.)
4. Retract the jack by pushing the operating switch
DOWN. (With the HB4500R, you can press the DOWN
button on the remote control – see page 4 for remote
control instructions.)
Note: The jack will stop automatically at the end of
the extension or retraction stroke (Smart Stop). If you
attempt to extend or retract the jack and it does not
respond, it may be at the end of the stroke. If the jack
fails to respond, try operating it in the opposite direction.
If it will not operate in either direction, then see the
troubleshooting guide.
5. Before driving, remove the foot or position it in the
highest position and completely retract the jack.
See www.huskytow.com for Warranty Information / Tech Support / Product Updates.

WARNING: Do not stack blocks under the jack’s
foot to increase the height. Stacked blocks may
become unstable and fall.
Under heavy use, the internal circuit breaker may
open, causing the motor to switch off. In this
case, release the operating switch, and wait 15
seconds for the breaker to reset before resuming
operation.
MANUAL OPERATION
(FOR BACK-UP & EMERGENCY USE)
1. Disconnect the jack from the power source. (Failure
to disconnect the power could result in serious injury.)
2. Remove the rubber access covers on the top of the
jack and on the side of the motor cover. See (Figure 1).
3. Insert the manual crank handle into the access hole
on the top of the jack, engaging the drive screw. See
(Figure 1).
4. While holding the crank firmly in place, install the
brake release handle on the brake lever and pull forward,
releasing the brake. See (Figure 1).
5. Rotate the manual crank handle counter-clockwise
to extend the jack, and clockwise to retract it. See
(Figure 1).
6. When the jack is at the desired height, first re-engage
the brake then remove the crank and brake release
handle. Replace the rubber covers. See (Figure 1).
WARNING: Always install the crank handle and
hold it firmly in place before releasing the brake
on a loaded jack. Due to the Husky
®
Brute’s
low-friction ball screw, if the crank is not held
firmly in place, the jack may runaway and the
crank may spin dangerously when the brake is
released.

REMOTE CONTROL
(ONLY INCLUDED WITH THE HB4500R)
Before using remote control, you must press the ON
button, the LEDs will flash momentarily to confirm the
remote is ON.
Press the UP button to extend the jack (raise the trailer).
Press the DOWN button to retract the jack (lower the
trailer).
See (Figure 3).
Disconnect the jack from the battery if the unit is not
in use, to avoid discharging the battery. If it is the only
draw on the battery, the remote receiver can drain a
fully-charged battery within 3 months.
If your battery becomes weak, the jack will extend more
slowly, and the low voltage protection feature will
eventually cause it to stop operating. It will be necessary
to recharge the battery; then operate the jack in the
opposite direction, at least momentarily, before you can
continue to extend the jack.
WARNING: Always press the OFF button and slide
the cover up when not in use to prevent accidental
remote operation. LEDs will flash momentarily to
confirm the remote has been turned OFF.

REPLACEMENT PARTS
Due to the design of the Husky®Brute’s low-friction
ball screw, the inner assembly of the jack does not
require regular lubrication. But to keep your jack in
good, functional condition, fully extend the jack and
clean the inner jack tube once per year. After cleaning,
coat the tube with a light grease or silicone spray
lubricant.

CAUSE SOLUTION
Open Internal
Circuit Breaker Wait 15 seconds for breaker to close.
Open Manual
Reset Circuit
Breaker
Reset the breaker by pressing the button on
the breaker.
Poor Ground
Check the connection between the negative
terminal on the battery and the vehicle, since
the jack is grounded to the vehicle chassis
through the star washers on the coupler.
Ensure the mounting hardware (bolts,
washers, and star washers) are in good con-
dition.
No or Low
Voltage
Check battery & electrical connections. Power
supplied must be at least 10 Volt DC. If the
battery is low, plug the trailer cable into the
tow vehicle, and start the tow vehicle to
provide power to the jack.
CAUSE SOLUTION
Engaged Brake
Disengage the brake by installing the brake
release handle on the brake lever and pulling
forward.
PROBLEM: Crank handle will not turn during manual operation

ALTERNATIVE 7-WAY PLUG WIRING
To wire the Husky®Brute jack through a 7-way plug
instead of wiring to the trailer battery.
1. Take the black wire from the jack and wire into the
black terminal of the 7-way plug.
2. Run a ground wire from the white terminal of the
7-way plug to one of the mounting bolts used to secure
the jack to the trailer with a ring terminal.
WARNING: The jack will only work while the
7-way plug is still connected to the 7-way plug on
the vehicle.
