The Husky Brute Electric Trailer Jack (models HB3000, HB4500 & HB4500R) with Smart Stop is designed to facilitate the raising and lowering of trailers, offering both electric and manual operation for convenience and emergency use. This device is an essential tool for trailer owners, providing robust lifting capabilities and user-friendly features.

Function Description

The primary function of the Husky Brute Electric Trailer Jack is to electrically extend and retract, allowing for easy hookup and unhooking of trailers. It is equipped with a "Smart Stop" feature that automatically halts operation at the end of the extension or retraction stroke, preventing over-extension or over-retraction and potential damage. For models HB4500R, a remote control is included, enabling wireless operation of the jack, which enhances convenience and safety by allowing the user to operate the jack from a distance. In situations where electrical power is unavailable or for backup, the jack can be manually operated using a crank handle. The jack also features LED work lights to illuminate the work area during nighttime hookups, improving visibility and safety.

• Mounting Hardware: Three (3) Grade 5, 1” long, 3/8"-16 UNC bolts, three (3) 3/8" flat washers, and three (3) 3/8" star washers (included). Bolts should be tightened to 15-20 lb-ft.
• Installation Time: Approximately 30 minutes

Usage Features

• Electric Operation: The jack is operated by pushing an "UP" or "DOWN" switch. The "Smart Stop" feature ensures the jack stops automatically at the end of its stroke. If the jack doesn't respond, it may be at the end of its stroke or the internal circuit breaker may have opened due to heavy use.
• Remote Control (HB4500R only): This model includes a remote control with "ON," "UP," and "DOWN" buttons. The remote must be turned "ON" before use, indicated by flashing LEDs. A crucial safety feature is the "OFF" button and sliding cover, which should be used when not in use to prevent accidental operation. The remote operates under FCC Rules, part 15, and is subject to conditions regarding interference.
• Manual Operation (Back-up & Emergency Use): For manual operation, the jack must first be disconnected from its power source. Users remove rubber access covers, insert the manual crank handle, and then install the brake release handle to disengage the brake. Rotating the crank handle counter-clockwise extends the jack, and clockwise retracts it. It is critical to hold the crank handle firmly in place before releasing the brake on a loaded jack, as the low-friction ball screw can cause the jack to run away and the crank to spin dangerously.
• Safety Lock Pin: A 3/8" safety lock pin is provided to secure the foot to the jack.
• Lower Support Plate: A lower support plate is required for operation and should be installed in the bottom of the trailer frame if not already present.
• Grounding: The jack is internally grounded. For aluminum frame trailers, a separate ground wire from a jack mounting bolt to the negative terminal of the trailer battery is recommended. Star washers are used during installation to penetrate paint and ensure direct metal-to-metal contact for proper grounding.
• Power Source Options: The jack can be wired directly to the trailer battery or, alternatively, through a 7-way plug connected to the tow vehicle's 12V battery power/auxiliary power terminal (black wire) and a ground wire from the 7-way plug's white terminal to a mounting bolt on the trailer.
• Low Voltage Protection: If the battery becomes weak, the jack will operate slower and eventually stop. Recharging the battery and operating the jack momentarily in the opposite direction may be necessary to resume normal function.

Maintenance Features

• Lubrication: Due to its low-friction ball screw design, the inner assembly of the jack does not require regular lubrication.
• Annual Cleaning: To maintain good functional condition, the inner jack tube should be fully extended and cleaned once per year. After cleaning, it should be coated with a light grease or silicone spray lubricant.
• Circuit Breaker Reset: In case of heavy use, the internal circuit breaker may open, causing the motor to switch off. Users should release the operating switch and wait 15 seconds for the breaker to reset before resuming operation. If a manual reset circuit breaker is used, it can be reset by pressing the button on the breaker.
• Troubleshooting Guide: The manual provides solutions for common issues such as an open internal circuit breaker, poor ground connection, no or low voltage, and the crank handle not turning during manual operation. For poor ground, checking connections and ensuring mounting hardware is in good condition is advised. For low voltage, checking battery and electrical connections and ensuring at least 10 Volt DC power is supplied is recommended. If the battery is low, plugging the trailer cable into the tow vehicle and starting the tow vehicle can provide power. If the crank handle won't turn, the brake may be engaged and needs to be disengaged using the brake release handle.
