ADDITIONAL IMPORTANT SAFETY INSTRUCTIONS
•WARNING: When using electric tools, basic safety precautions should always be followed to reduce risk
of fire, electric shock, and personal injury, including the following:
• Do not incinerate the battery even if it is severely damaged or is completely worn out. The battery can
explode in a fire. Check with local codes for possible special disposal instructions.
• If any leakage of liquid from the battery cells occurs, discontinue use immediately and return the battery to
your local Black & Decker Service Center or authorized service facility.
• Never attempt to open the battery for any reason. If the plastic housing of the battery breaks or cracks,
immediately discontinue use and do not recharge.
• Do not charge appliance in rain or in wet locations.
• Use only the following type and size battery: Black & Decker 244373 - 12V.
• Use only Black and Decker 12V charger 244374.
• Exercise care in handling batteries in order not to short the battery with conducting materials such as rings,
bracelets and keys. The battery or conductor may overheat and cause burns.
• Do not open or mutilate the battery. Released electrolyte is corrosive and may cause damage to the eyes or
skin. It may be toxic if swallowed.
• If the battery case cracks due to a fall or other impact and the electrolyte gel leaks out, wipe it up with a
cloth, neutralize the acid with any alkaline substance such as ammonia solution of baking soda. If the
electrolyte gets on your skin, immediately flush with water and consult a doctor.
• Do not use battery for anything other than with this product or other designated Black & Decker product.
ASSEMBLY INSTRUCTIONS
• WARNING: The guard must always be on the tool to protect the user.
UNIT ASSEMBLY
Layout the unit as shown in figure 2. Remove the nut and bolt from the upper section (left portion of Figure 2).
Slide the bottom portion into the upper portion as indicated. The two halves should snap together. Re-insert the
nut and bolt to the upper section, and tighten bolt. The unit should now be rigidly secured.
GUARD ASSEMBLY
Remove the screw from the guard and insert the guard into the slot (marked by arrows) in the trimmer head as
shown in Figure 3. Ensure the guard is fully inserted. Re-insert the screw through the trimmer head and into
the guard and tighten as shown in figure 4.
NEVER OPERATE THE TOOL WITHOUT THE GUARD PROPERLY IN PLACE. Use of the unit with out having
installed the guard will cause the motor to overheat, and void the warranty.
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.
• If the battery case cracks due to a fall or other impact and the electrolyte gel leaks out, wipe it up with a
cloth, neutralize the acid with any alkaline substance such as ammonia solution or baking soda. If the
electrolyte gets on your skin, immediately flush with water and consult a doctor.
• Your trimmer is equipped with a charger bracket that may be mounted firmly to a wall 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 tool up, out of the
way and ensures a good, solid contact between the charging terminals.
MOUNTING THE CHARGER BRACKET
1. If you intend to mount, the charger bracket on a wall, follow the instructions listed below.
2. Remove the two screws and plastic anchors from the plastic bag.
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.
4. Drill a .250” (6 mm) diameter hole at each marked location.
5. Insert the plastic anchors into the holes and insert one of the screws in each one. Tighten the screws until
the heads are above the anchors just enough so that the charger bracket will fit between the anchor and
the screw head.
6. Place the charger bracket on the wall (narrow 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 it sits 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 7 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 7).
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.
OPERATING INSTRUCTIONS
• CAUTION: ALWAYS WEAR EYE PROTECTION.
•
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.
• To turn trimmer on, pull back on the lock out button, shown in Figure 1, at the same time, squeeze the
trigger switch. To turn the tool off, release the trigger switch.
• Angle unit as shown in Figure 5.
• Slowly swing trimmer side-to-side as shown in Figure 6.
CUTTING LINE
LINE FEEDING
Your trimmer only uses .065” (1.65 mm) diameter, ROUND nylon line to cut grass and weeds quickly and
easily. During use, the tip of the nylon line will become frayed and worn. Gently bump the feed head of the
trimmer on the ground to release a fresh length of line. Cutting line will wear faster and require more feeding
if the cutting is done along sidewalks or other abrasive surfaces or heavier weeds are being cut.
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. Turn the unit upside down.
2. Press the release tabs on the line hub cover and remove by pulling it straight off (Figure 8).
3. 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.)
4. Unwrap about one foot (30 cm) of line to ensure that it’s undamaged. If it is okay, rewind it and insert the
line end through the eyelet in the spool hub as shown in figure 9. Ensure the spring is in place under the
spool. Pull the line through the hole to maintain tension while placing the spool down into the hub with
the arrow up, as shown in figure 9.
5. Press the spool down GENTLY on the spring and rotate it until you feel it drop into place. Take care to
keep the line from becoming trapped under the spool.
6. Snap the hub cap back on hold the tool in the trimming position, and turn the tool on. In a few seconds
or less you’ll hear the nylon line being cut to the proper length; if not bump the feed head gently on the
ground to initiate a fresh length of line.
SPOOL OR LINE REPLACEMENT (Use 0.065” diameter ROUND line only
.)
1. Turn the unit upside down.
2. Press the release tabs on the line hub cap, as shown in Figure 8 and remove the cap by pulling it straight
off.
3. Remove the spool from the tool and remove and discard all line on spool.
4. Choose either OPTION 1 or OPTION 2 below for spool or line replacement.
5. Insert the line end through the eyelet in the spool hub, as shown in figure 9. Ensure the spring is in place
under the spool. Pull the line through the hole to tighten tension while placing the spool down into the
hub, as shown in Figure 9.
6. Press the spool down GENTLY on the spring and rotate it until you feel it drop into place. Take care to
keep the line from becoming trapped under the spool.
7. Snap the hub cap back on holdr the tool in the trimming position, and turn the tool on. In a few seconds
or less you’ll hear the nylon line being cut to the proper length; if not bump the feed head gently on the
ground to release a fresh length of line.
OPTION 1: ACCESSORY REPLACEMENT SPOOL
Use replacement spool Model No. RS-136.
OPTION 2: REWINDING SPOOL USING BULK LINE
Bulk line for your trimmer is available at extra cost from your local dealer or Black & Decker Service
Center. To install bulk line, follow the steps below. (Use 0.065” diameter round LINE ONLY).
1. Insert one end of the bulk line into the hole in the spool as shown in Figure 10 about 1/8” (3.2mm).
2. Snugly and evenly wind the bulk line onto the spool in the direction of the arrow on the spool, (figure 11),
until the line builds up to the notches in the spool rim. Do not overfill spool. The spool holds about 20 feet
(6 m) of line.
MAINTENANCE
CLEANING AND STORAGE
1. Keep the air intake slots (Figure 5) 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. DO NOT immerse tool in water or squirt it with a hose. DO NOT allow any liquid to get inside it.
5. Do not store the tool on or adjacent to fertilizers, gasoline, or other chemicals.
6. DO NOT clean with a pressure washer.
7. 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.
ACCESSORIES
• Reload nylon line (either bulk or prewound replacement spool) as shown in this manual. Use
Black & Decker Replacement spool, Model No. RS-136.
• USE ONLY 0.065” (1.65 mm) diameter ROUND monofilament trimmer line. Do not use heavier
gauge line, as it will overload the motor and cause overheating. The unit functions properly only with
0.065” diameter ROUND monofilament line. This line is available at your local dealer or Black & Decker
Service Center.
