The tool is locked in the edger position. 4. To operate as a maintenance edger, position trimmer above sidewalk as shown in figure 10. 5. Return to trimming position by turning the tool off, pushing in direction of arrow and rotating the trimmer head counter clockwise until it stops. CLEARING JAMS AND TANGLED LINES From time to time, especially when cutting thick or stalky weeds, the line feeding hub may become clogged with sap or other material and the line will become jammed as a result. To clear the jam, follow the steps listed below. 1. Press the release tabs on the line hub cap, as shown in figure 18 and remove the cap by pulling it straight off. 2. Lift the spool of nylon line out of the hub and clear any broken line or cutting debris from the spool area. (If you plan to replace the spool or rewind it, this is the place to do so, otherwise, move on.) 3. Unwrap about one foot (30 cm) of line to ensure that it’s undamaged. If it is OK rewind it and insert the line end through the eyelet in the spool hub as shown in figure 19. Pull 4 in. (10 cm) of the line through the hole and maintain tension while placing the spool down into the hub with the arrow up, as shown in figure 20. 4. Press the spool down GENTLY and rotate it until you feel it drop into place. (When in place, the spool will turn a few degrees left and right freely). Take care to keep the line from becoming trapped under the spool. 5. Snap the hub cap back on, and power the tool on. In a few seconds or less you’ll hear the nylon line being cut automatically to the proper length. SPOOL OR LINE REPLACEMENT USE ONLY .065 in. (1.65mm) DIAMETER NYLON MONOFILAMENT LINE. Heavier line will overload the motor and cause overheating. This line is available at your local dealer or authorized service center. Do not use fishing line or other lines that are not recommended. 1. Perform step 1 above to remove cap. 2. Remove the spool from the tool and remove and discard all line on the spool. 3. Choose either OPTION 1 or OPTION 2 below for spool or line replacement. Perform steps listed under Option 1 or Option 2, then continue with steps 4 through 6 below. 4. Insert the line end through the eyelet in the spool hub, as shown in figure 19. Pull the line through the hole to maintain tension while placing the spool down into the hub, as shown in figure 20. 5. Press the spool down GENTLY and rotate it until you feel it drop into place. (When in place, the spool will turn a few degrees left and right freely). Take care to keep the line from becoming trapped under the spool. 6. Snap the hub cap back on, and power the tool on. In a few seconds or less you’ll hear the nylon line being cut automatically to the proper length. OPTION 1: ACCESSORY REPLACEMENT SPOOL Use Black & Decker replacement spool Model No. AF-100. Discard old spool. OPTION 2: REWINDING SPOOL USING BULK LINE Bulk line for your trimmer/edger is available at extra cost from your local dealer or Black & Decker Service Center. To install bulk line, follow the steps below. (Use .065 in. diameter ROUND line only) 1. Insert one end of the bulk line into the hole in the spool as shown in figure 21 about 1/2 in. (12 mm). 2. Hold the line in the hole and pull the rest of the line through the slot in the spool. 3. Snugly and evenly wind the bulk line onto the spool in the direction of the arrow on the spool until the line builds up to the notches in the spool rim. Do not overfill spool. The spool holds 30 feet (10 m) of line.

Attach the edge guide to the housing by locating the two ends into the holes in the housing. 3. See figure 2 for edge guide assembled on the trimmer. 4. Remove the guard attachment screw from the guard. Slip the guard onto the trimmer housing and lineup the screw hole in the guard with the screw hole in the housing (figure 3). 5. Insert the guard attachment screw to secure the guard in place as shown in figure 4. 6. Attach extension cord to cord retainer as shown in figures 5 & 6. OPERATING INSTRUCTIONS FORCATALOG # ST4500 BUMP FEED TRIMMER LINE FEED Your trimmer uses .065 in. (1.65 mm) diameter, ROUND nylon line to cut grass and weeds quickly and easily. 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. As you use the trimmer, the string will get shorter due to wear. Gently bump the unit on the ground and the line will feed.
