BATTERY
THE LEAD ACID BATTERY FOR YOUR TRIMMER IS ONLY PARTIALLY CHARGED AT
THE FACTORY. BEFORE USING YOUR TRIMMER, THE BATTERY MUST BE CHARGED
FOR A MINIMUM OF 24 HOURS.
• Your trimmer is equipped with a charger bracket that may be mounted firmly to a walt in your
garage, shed or similar building. (Hardware for hanging the bracket is included in the plastic
bag packed with the trimmer.) Charging your battery in this bracket is very convenient
because it hangs the toot up, out of the way and ensures a good, solid contact between the
charging terminals.
MOUNTING THE CHARGER BRACKET (FIGURE 4)
1. If you intend to mount the charger bracket on a wall, follow the instructionslisted below.
2. Use the hardware provided (Figure 1D) only if hanging on conventional hollow walt
construction such as drywall over studs. If not, use the appropriate fasteners for the
particular wall material.
3. Use the charger bracket to mark the locations of the holes required. Be sure to mount the
bracket high enough so that the trimmer can hang freely from it; about 4 feet (1.2m) from
the floor and close enough to an electrical outlet to plug-in charging transformer.
4. a) Conventional hollow wall: Drill a .250 in. (6mm) diameter hole at each marked
location. Insert the plastic anchors supplied into the holes and insert one of the screws into
each anchor.
b) Alternative wall materials: Insert fasteners as appropriate making sure screw heads
are small enough to fit through bracket.
5. Tighten the screws until the heads are above the walt just enough so that the charger
bracket will fit between the wall and the screw head.
6. Place the charger bracket on the wall (hook end up) and make sure that the power cord is
positioned in the side slot. Press the charger bracket over the screw heads and slide it
down until itsits firmly on the screws.
7. Firmly tighten both screws.
LED INDICATOR LIGHT
The unit is equipped with a red LED charging indicator light, located on the upper left side of
the unit (Figure 1). The indicator light will come on when the unit is properly connected to
the charging base and the power plug is inserted into the electrical outlet. The light will
remain on, so long as the unit is properly connected to the powered charging base. It is
recommended to store the unit on the charger during the growing season, with the charger
plugged in, to have the battery charged for the next use.
TO CHARGE YOUR BATTERY, FOLLOW THE STEPS BELOW
1. Install the trimmer onto the charger bracket by positioning the handle cavity, shown in
Figure 4 over the hook of the charger bracket.
2. Rotate the trimmer down, keeping the hook engaged with the handle cavity, and position
the charge port over the bracket's charge pin (Figure 4).
3. Plug the charger into any standard 120 volt, 60Hz outlet. Charging will be automatically
controlled until you remove the trimmer from the bracket.
4. It is recommended that the trimmer be left on charge, during the growing season. For
winter or other extended periods of storage, it is recommended that the unit be fully
charged prior to storage.
OPERATION INSTRUCTIONS
z_ CAUTION: ALWAYS WEAR EYE PROTECTION.
Z_ 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 tool, such as barbs at the base of a
chain link fence.
OPERATE THE TRIMMER/EDGER
• To turn trimmer on, pull the lock out button, shown in Figure 1, backwards and, then
squeeze the trigger switch. To turn the tool off, release the trigger.
• Slowly swing trimmer side-to-side as shown in Figure 5.
• To convert for maintenance edging, turn off the tool. (See Figure 6) Holding the trimmer with
one hand by the auxiliary handle, grasp the trimmer head collar and push in direction of
arrow and rotate the trimmer head clockwise (when viewed from the switch end) until it
stops, (half turn), release your hand. The tool is locked in the edger position.
Rotate the wire edge guide forward and down into place before edging, as shown in Figure 7.
• To operate as a maintenance edger, position trimmer above sidewalk as shown in Figure 8.
• Return to trimming position by turning the toot off, push in direction of arrow and rotating the
trimmer head counter clockwise until it stops. When using the tool in the trimmer mode you
may choose to fold the wire edge guide up out of the way.
CUTTING LINE
LINE FEEDING
Your trimmer uses .065 in. (1.65 mm) diameter, ROUND nylon line to cut grass and
weeds quickly and easily. During use, the tip of the nylon line wilt become frayed and
worn and the special self feeding line hub will automatically feed and trim a fresh length
of line. Cutting line wilt 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. The
advanced automatic line feeding mechanism senses when more cutting line is needed
and feeds and trims the correct length of line whenever its required. DO NOT BUMP unit
on ground in attempt to feed line or for any other purposes.
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 9 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 10. 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 11.
4. Press the spool down GENTLY and rotate it until you feel it drop intoplace. (When in place,
the spool wilt 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 toot 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 .065 in. diameter ROUND line only)
1. Perform step 1above 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 10. Pull the
line through the hole to maintain tension while placing the spool down into the hub, as
shown in Figure 11.
5. Press the spool down GENTLY and rotate it until you feet it drop into place. (When in place,
the spool wilt 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 toot 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 12 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, shown
in Figure 12.
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. (Figure 12) Do not overfill
spool. The spool holds 30 feet (10 m) of line.
