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
polarized 2 wire or 3 wire 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.
SPECIFIC WARNING
WARNING: Some dust created by this
product contains chemicals known to the
State of California to cause cancer, birth
defects or other reproductive harm.
Some examples of these chemicals are:
• compounds in fertilizers
• compounds in insecticides, herbicides
and pesticides
• arsenic and chromium from
chemically treated lumber
To reduce your exposure to these
chemicals, wear approved safety
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.

• The guard must be installed before
trimming or edging - if not, the motor
will overheat.
• When replacing the line, use only .065”
diameter ROUND line - otherwise the
unit will not function properly.
• 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.
SAFETY WARNINGS
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, SJTW-A, or SJTOW-A.
