ignite fumes.
especially children.
• IMPORTANT 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 tool
and guard are designed to reduce the
danger. However, the following special
precautions should be taken:
• STORE IDLE TOOLS INDOORS –
When not in use, tools 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.
• MAKE SURE that other persons and
pets are at least 100 feet away.
• TO REDUCE THE RISK of rebound
(ricochet) injury, work going away from
any nearby solid object such as wall,
steps, large stone, tree, etc. Use great
care when working close to solid objects
and where necessary, do edging or
trimming by hand.

trigger.
• MAINTAIN APPLIANCES WITH CARE
– Follow instructions for lubricating and
changing accessories. Inspect extension
cords periodically and replace if
damaged. Keep handles dry, clean and
free from oil and grease.
• CHECK DAMAGED PARTS – Before
further use of the appliance, a guard or
other part that is damaged should be
carefully checked to determine that it
will operate properly and perform its
intended function. Check for alignment
of moving parts, binding of moving
parts, breakage of parts, mounting, and
any other condition that may affect its
operation. A guard or other part that is
damaged should be properly repaired or
replaced by a qualified service facility
unless otherwise indicated elsewhere in
this manual.
• DO NOT FORCE THE TOOL – At a rate

• DAMAGE TO UNIT – If you strike or
become entangled with a foreign object,
stop tool immediately, unplug, check for
damage and have any damage repaired
before further operation is attempted.
Do not operate with a broken hub or
spool.
WARNING: When servicing double
insulated tools, USE ONLY IDENTICAL
REPLACEMENT PARTS. Replace or
repair damaged cords.
• DAMAGE TO CORD – Keep power
cord away from rotating line. If you
damage the cord, unplug it from the
power supply before moving the tool or
examining the damage. A damaged cord
must be replaced before further use.
WARNING: To prevent electrical shock
hazard, use only with an extension

connect extension cords to a fused line
or one protected by a circuit breaker.
• 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

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.
IMPORTANT WARNINGS FOR STRING TRIMMERS
• 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
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.
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.

6. Snap the hub cover and spring back on
and turn the tool on. In a few seconds
or less you’ll hear the nylon line being
cut automatically to the proper length.
10
CUTTING LINE
Your trimmer uses only .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 and the special self
feeding line hub will automatically feed
and trim a fresh length of line. 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.
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.

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. Unplug the trimmer.

and turn the tool on. In a few seconds
or less you’ll hear the nylon line being
cut automatically to the proper length.
REWINDING SPOOL
Use .065” diameter ROUND line only. Do
not use heavier gauge line; it will
overload motor and cause overheating.
1. Insert line end about 1/4” into the
spool hole.
2. Snugly and evenly wind the 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
