OPERATING INSTRUCTIONS

WARNING: Always use proper eye protection that conforms to ANSI Z87.1 (CAN/CSA Z94.3) while operating this power trimmer.

WARNING: Remove the battery before making any assembly, adjustments, or changing accessories. Such preventive safety measures reduce the risk of starting the trimmer accidentally. CAUTION: Before you begin trimming, only use the appropriate type of cutting line.

CAUTION: Inspect area to be trimmed and remove any wire, cord, or string-like objects which could become entangled in the rotating line or spool. Be particularly careful to avoid any wire which might be bent outwardly into the path of the trimmer, such as barbs at the base of a chain link fence.

Switching on and off

• To switch the trimmer on, push the lock off button (shown in inset, figure J) across from either side and then squeeze the trigger switch.

• To switch the trimmer off, release the trigger switch.

OPERATING THE TRIMMER

• With the unit on, angle unit and slowly swing the trimmer side to side as shown in figure J.

• Maintain a cutting angle of 5° to 10° as shown in figure J1. Do not exceed 10° (figure J2). Cut with the tip of the line. To keep distance from hard surfaces use edge guide (6).

• Maintain a minimum distance of 24 inches (609.6 mm) between the guard and your feet as shown in figure J1. To acheive this distance adjust the overall height of the trimmer as shown in figure I.

CONVERT TO EDGING MODE

WARNING: When being used as an Edger, stones, pieces of metal and other objects can be thrown out at high speed by the line. The trimmer and guard are designed to reduce the danger. However, MAKE SURE that other persons and pets are at least 100 feet (30m) away.

• To operate as a maintenance edger, turn the collar (4) as shown in figure I.

• Hold the metal shaft and rotate the lower housing 180° until trimmer is in the position shown in figure K.

• Turn the collar back until tight.

• Position the trimmer with the wire guide (6) along the surface as shown in figure L.

• Return to the trimming position by loosening the collar and rotating the lower housing back 180°.

• Turn the collar until tight. When using the trimmer, retract the wire edge guide to the original position, out of the way.

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 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.
