The RBRC™ Seal

The RBRC™ (Rechargeable Battery Recycling Corporation) Seal on the LI-ION battery (or battery pack) indicates that the costs to recycle the battery (or battery pack) at the end of its useful life have already been paid by Black & Decker.

RBRC™ in cooperation with Black & Decker and other battery users, has

established programs in the United States to facilitate the collection of spent LI-ION batteries. Help protect our environment and conserve natural resources by returning the spent LI-ION battery to an authorized Black & Decker service center or to your local retailer for recycling. You may also contact your local recycling center for information on where to drop off the spent battery. RBRC™ is a registered trademark of the Rechargeable Battery Recycling Corporation.

Maintenance

WARNING: To avoid serious injury, remove the battery from the trimmer before performing any maintenance.

CAUTION: To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment should be performed by authorized service centers or other qualified service organizations, always using identical replacement parts.

1. Keep the air intake slots clean to avoid overheating.

2. Your trimmer line can dry out over time. To keep your line in top condition, store spare pre- wound spools or bulk line in a plastic, sealable bag with a tablespoon of water.

3. Plastic parts may be cleaned by using a mild soap and a damp rag.

4. The line cutter on the edge of the guard can dull over time. It is recommended you periodically touch-up the sharpness of the blade with a file.

Troubleshooting

TRIMMER runs slowly

• Remove Battery from tool.

• Check that the spool housing can rotate freely. Carefully clean it if necessary.

• Check that the cutting line does not protrude more than approximately 5-3/8 inches (136mm) from the spool. If it does, cut it off so that it just reaches the line trimming blade.

Automatic line feed does not work

• Remove Battery from tool.

• Remove the spool cap.

• Pull the cutting line until it protrudes approximately 5-3/8 inches (136mm) from the spool. If insufficient cutting line is left on the spool, install a new spool of cutting line.

• Ensure that the line is not crisscrossed on the spool as detailed in figure R. If it is, unwind the cutting line, then wind it back on the spool neatly so that the lines do not cross.

• Ensure the beginning of the cutting line is pulled tight against the spool as shown in figure Q.

• Align the tabs on the spool cap with the cut outs in the housing.

• Push the spool cap onto the housing until it snaps securely into place.

• If the cutting line protrudes beyond the trimming blade, cut it off so that it just reaches the blade. If the automatic line feed still does not work or the spool is jammed, try the following suggestions:

• Carefully clean the spool and housing.

• Remove the spool and check if the lever in the spool housing can move freely.

• Remove the spool and unwind the cutting line, then wind it on neatly again. Replace the spool into the housing.

LST400R, LST400, LST420R, LST420 specifications

Black & Decker is recognized for producing high-quality outdoor power tools, and their string trimmers, particularly the LST420, LST420R, LST400, and LST400R models, are exemplary of their innovation and commitment to efficiency. These cordless electric trimmers combine robust performance with user-friendly features, catering to both novice and experienced gardeners.

The LST420 and LST420R models feature a powerful 40V lithium-ion battery, ensuring extended run times and plenty of cutting power. Both models utilize a premium 12-inch cutting width, allowing users to trim and edge grass and weeds efficiently. Weighing in at around 6.5 pounds, these trimmers are lightweight, making them easy to maneuver and reducing user fatigue during extended periods of use.

One of the standout features of the LST420 and LST420R is the automatic feed spool, which continuously feeds the line when needed, eliminating interruptions during work. Furthermore, users can easily switch between trimming and edging modes with a simple turn of the shaft, thanks to the innovative pivoting head design. This feature enhances versatility, allowing users to achieve a professional finish on various landscaping tasks.

The LST400 and LST400R also sport the reliable 40V lithium-ion battery and 12-inch cutting width. However, these models feature a slightly different design. The LST400 is designed with a telescoping shaft that can be adjusted for different heights, offering added comfort and control for users of varying statures. With the addition of a secondary handle, it provides improved stability during operation.

All four models boast a relatively quiet operation compared to gas-powered trimmers, which adds convenience to residential areas while minimizing noise pollution. The efficient brushless motor technology found in these trimmers enhances durability and runtime, further highlighting Black & Decker's commitment to sustainability and user convenience.

In summary, the Black & Decker LST420, LST420R, LST400, and LST400R offer a blend of power, versatility, and user-friendly features. With their lightweight designs, automatic feed spooling, adjustable shafts, and efficient battery systems, they are ideal choices for maintaining a neat and tidy lawn while ensuring comfort and ease of use for the operator. These trimmers embody the brand's dedication to quality and innovation in outdoor power tools, making them a reliable choice for homeowners and gardening enthusiasts alike.
