NOTE: When in acceleration mode (#2), runtime will be decreased as compared to when trimmer is in extended runtime mode (#1).

Cutting Line / LINE FEEDING

Your trimmer uses .065 inch (1.65 mm) diameter, ROUND nylon line. During use, the tips of the nylon lines will become frayed and worn and the special self feeding spool will automatically feed and trim a fresh length of line. Do not bump trimmer on ground in attempt to feed line or for any other purposes.

Cutting line will wear faster and require more feeding if the cutting or edging is done along sidewalks or other abrasive surfaces or heavier weeds are being cut.

REPLACEMENT ACCESSORIES

CAUTION: Before you begin trimming, only use the appropriate type of cutting line. Use Black & Decker replacement spool Model No. AF-100, and replacement cap RC-100. Reload nylon line (either bulk or prewound replacement spool) as shown in this manual.

• USE ONLY .065 inch (1.65 mm) DIAMETER ROUND NYLON MONOFILAMENT LINE. Do not use serrated or heavier gauge line, as they will overload the motor and cause overheating, and will not feed properly. This line is available at your local dealer or authorized service center.

• Other replacement parts (guards, spool caps, etc.) are available through Black & Decker service centers. To find your local service location call: 1-800-544-6986 or visit www.blackanddecker.com.

WARNING: The use of any accessory not recommended by Black & Decker for use with this trimmer could be hazardous.

REPLACING THE SPOOL

• Remove battery from trimmer.

• Depress the tabs (15) and remove the spool cap (9) from the spool housing (16) in the trimmer head (figure M).

• For best results, replace spool with Black & Decker model # AF-100.

• Grasp empty spool with one hand and spool housing with other hand and pull spool out.

• If lever (17) in base of housing becomes dislodged, replace in the position as shown in figure N before inserting new spool into housing.

• Remove any dirt and grass from the spool and housing.

• Unfasten the end of the cutting line and guide the line into the eyelet (19) figure O.

• Take the new spool and push it onto the boss (18) (figure N) in the housing. Rotate the spool slightly until it is seated. The line should protrude approximately 5-3/8 inches (136mm) from the housing.

• Align the tabs on the spool cap with the slots (20) in the housing (figure O).

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

CAUTION: To avoid trimmer damage, if the cutting line protrudes beyond the trimming blade, cut it off so that it just reaches the blade.

REWINDING SPOOL FROM BULK LINE (use only .065 in. ROUND diameter line) Bulk line is also available for purchase from your local retailer. NOTE: Hand wound spools from bulk line are likely to become tangled more frequently than Black & Decker factory wound spools. For best results, factory wound spools are recommended.

To install bulk line, follow the steps below:

• Remove battery from trimmer.

• Remove the empty spool from the trimmer as described in “REPLACING THE SPOOL”.

• Remove any remaining cutting line from the spool.

• Make a fold at the end of the cutting line at about 3/4 inch (19mm) (21). Feed the cutting line into one of the line anchoring slots (22) as shown in figure P.

• Insert the 3/4 inch (19mm) end of the bulk line into the hole (23) in the spool adjacent to the slot as shown in figure Q. Make sure the line is pulled tight against the spool as shown in figure Q.

• Wind the cutting line onto the spool in the direction of the arrow on the spool. Make sure to wind the line on neatly and in layers. Do not crisscross (figure R).

• When the wound cutting line reaches the recesses (24), cut the line. (figure Q).

• Fit the spool onto the trimmer as described in “REPLACING THE SPOOL”.

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.
