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.

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.
