Husky Hb4500 User manual

Brute Electric Jack (4,500 & 3,000 lb)

with Smart StopTM

Read and follow all instructions. If you do not understand the proper use of the product, ask your dealer/in-

staller for assistance. Never remove any warning decals from the product.

Warning: Keep hands, feet and body clear of the jack and trailer to avoid the risk of injury or death!

Installation

Warning: Before installation, compare the lift capacity of the Husky®Brute with your trailer to ensure safe operation of the jack.

1. Park the trailer on a level surface and block 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, saving the washers and bolts.

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. Place the star washers between the

flat washers and the mounting plate as shown in Figure 1. 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 ft•lb.

Tip: The salvaged bolts from the old jack are acceptable for reuse if they are grade 5 and in good

condition.

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.

7. Install the manual reset circuit breaker by either crimping or soldering one of the wires to the jack lead (Black).

Connect the other wire 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.

Warning: When using an extension wire, DO NOT use a wire smaller than #10

gauge.

Operation

1. Park your trailer on a level surface and block all dolly and 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.

Warning: Do not stack blocks under the jack’s foot to increase the height. Stacked

blocks may become unstable and fall.

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 2 for remote control instructions.)

Warning: 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.

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 2 for remote control instructions.)

Note:The jack will stop automatically at the end of the extension or retraction stroke. 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.

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.

3. Insert the manual crank handle into the access hole on the top of the jack, engaging the drive screw.

4. While holding the crank firmly in place, install the brake release handle on the brake lever and pull forward,

releasing the brake.

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 run away and the crank may spin dangerously when the brake is

released.

5. Rotate the manual crank handle counter-clockwise to extend the jack, and clockwise to retract it.

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.

Remote Control (only included with the HB4500R) Before using remote control, you must press the ON button.

Press the UP button to extend the jack (raise the trailer).

Press the DOWN button to retract the jack (lower the trailer).

Warning: Always press the OFF button and slide the cover up when not in use to lock the jack in place and prevent accidental operation.

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.

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this

device must accept any interference received, including interference that may cause undesired operation.

Maintenance

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.

Trouble Shooting

Problem: Motor isn’t operating.

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.

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.

Problem: Crank handle won’t turn during manual operation.
