• AVOID DANGEROUS ENVIRONMENTAL CONDITIONS – Do not use electric appliances in
damp or wet locations. Don't use the appliance in the rain.
• DO NOT OPERATE trimmer/edgers in gaseous or explosive atmospheres. Motors in these
appliances normally spark, and the sparks might ignite fumes.
• STORE IDLE APPLIANCES INDOORS – When not in use, appliances should be stored
indoors in a dry locked-up place out of reach of children.
• GROUND FAULT CIRCUIT INTERRUPTER (GFCI) protection should be provided on the
circuits or outlets to be used for the gardening appliance. Receptacles are available
having built in GFCI protection and may be used for this measure of protection.
• SECURE EXTENSION CORD using the cord retainer shown in Figure 4.
• STAY ALERT– Watch what you are doing. Use common sense. Do not operate appliance
when you are tired.
• MAINTAIN APPLIANCES WITH CARE – Keep cutting edge sharp and clean for best
performance and to reduce the risk of injury. Follow instructions for lubricating and changing
accessories. Inspect appliance cord periodically, and if damaged, have it repaired by an
authorized service facility. Inspect extension cords
periodically and replace if damaged. Keep handles dry, clean, and free from oil and grease.
• CHECK DAMAGED PARTS – Check for alignment of moving parts, binding of moving parts,
breakage of parts, mounting, and any other condition that may affect its operation. Before
further use of the appliance, a guard or other part that is damaged should be repaired or
replaced by an authorized service center unless otherwise indicated elsewhere in this
manual.
WARNING: When servicing double insulated tools, USE ONLY IDENTICAL
REPLACEMENT PARTS. Replace or repair damaged cords.
WARNING: To prevent electrical shock hazard, use only with an extension cord suitable
for outdoor use. Always connect extension cords to a fused line or one protected by a circuit
breaker.
• FOR HOUSEHOLD use only.
• KEEP GUARDS IN PLACE AND IN WORKING ORDER.
• KEEP HANDS AND FEET AWAY FROM CUTTING AREA.
ADDITIONAL SAFETY WARNINGS:
• EXTENSION CORDS. Make sure your extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to carry the current your product will draw.
An undersized extension cord will cause a drop in line voltage resulting in loss of power and
overheating. The table below shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord. To reduce the risk of disconnection of the appliance from the
extension cord during operation, use the extension cord retainer described in this manual.
WARNING: Outdoor use extension cords:
To reduce the risk of electric shock, use only with an extension cord intended for outdoor
use, such as an extension cord of type SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJOW-A,
DEC. '05
SJTW-A, or SJTOW-A.

DOUBLE INSULATION
NOTE: This symbol denotes Double Insulation. Double insulated tools are constructed
throughout with two separate layers of electrical insulation or one double thickness of
insulation between you and the tool's electrical system. Tools built with this insulation system
are not intended to be grounded. As a result, your tool is equipped with a two prong plug
which permits you to use extension cords without concern for maintaining a ground
connection.
NOTE: Double insulation does not take the place of normal safety precautions when operating
this tool. The insulation system is for added protection against injury resulting from a possible
electrical insulation failure within the tool.
REPLACEMENT PARTS: When servicing all tools, USE IDENTICAL REPLACEMENT
PARTS.
POLARIZED PLUGS
Repair or replace damaged cords.
To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider
than the other). This equipment must be used with a suitable 3 wire outdoor extension cord.
Polarized connections will fit together only one way. Make sure that the receptacle end of the
extension cord has large and small blade slot widths. If the plug does not fit fully into the
extension cord, reverse the plug. If it still does not fit, obtain a suitable extension cord. If the
extension cord does not fit fully into the outlet, contact a qualified electrician to install the proper
outlet. Do not change the tool plug or extension cord in any way.
IMPORTANT WARNINGS FOR STRING TRIMMERS
• The guard must be installed before trimming or edging - if not, the motor will overheat.
• When replacing the AFS outfeed line, use only .050" (1.27mm) diameter TWISTED line -
otherwise the unit will not function properly.
• When replacing the HDL fixed line use only Black & Decker part number # HDL-CA
• Do not bump the feed head against the ground - it will disrupt the feed mechanism.
• Angle tool slightly (5˚ to 10˚) when trimming.
• Always use the cord retainer.
• Wear long pants and substantial footwear to protect yourself from injury caused by flying
debris. This is especially important when edging with the appliance.
