MAINTENANCE SAFETY
WARNING: Disconnect unit from the

nance, or when changing trimmer line.
S Maintain unit according to recommended
procedures. Keep cutting line at proper
length. Follow instructions for changing
trimmer line.
S Have all service and maintenance not ex-
plained in this manual performed by an au-
thorized service dealer to avoid creating a
hazard.
S Keep the extension cord clear of operator
and obstacles at all times. Do not expose
cords to heat, oil, water, or sharp edges.
S To avoid the possibility of electric shock,
avoid body contact with any grounded con-
ductor, such as metal fences or pipes.
S Ground Fault Circuit Interrupter (GFCI)
protection should be provided on circuit or
outlet to be used. Receptacles are avail-
able having built-in GFCI protection and
may be used for this measure of safety.
S Never douse or squirt the unit with water or
any other liquid. Clean unit and labels with
a damp sponge. Keep handles dry, clean,
and free from oil and grease.
S Keep the air vents clean and free of debris
to avoid overheating the motor. Clean after

underside of shield) cannot cause injury.
S Store unit indoors in a high, dry place out of

S Do not hang unit so that the trigger switch is
depressed.
UNIT SAFETY
S Inspect unit before use. Replace damaged
parts. Make sure all handles, guards, and
fasteners are in place and securely fas-
tened. Parts that are damaged must be re-
paired or replaced by an authorized service
dealer These include head parts that are
cracked, or chipped, guards, and any other
part that is damaged.
DOUBLE INSULATION
CONSTRUCTION
This unit is double insulated to help protect
against electric shock. Double insulation
constructionconsists of two separate “layers”
of electrical insulation instead of grounding.
Tools built with this insulation system are not
intended to be grounded. No grounding
means is provided on this unit, nor should a
means of grounding beadded to this unit. As a
result, the extension cord used with your unit
can be plugged into any standard 120 volt
electrical outlet.
S Do not repair unit yourself.
S Use only 0.065 inch (1.65 mm) diameter
recommended trimmer line(see USER RE-
PLACEABLE SERVICE PARTS in the
SERVICE AND ADJUSTMENTS section).
Never use wire, rope, string, etc.
S Use specified trimmer spool. Make sure
spool is properly installed and all parts are
securely fastened.
S Use only WEED EATER replacement parts
and accessories as recommended.
Safety precautions must be observed when
operating any electrical tool. The double in-
sulation system only provides added protec-
tion against injury resulting from an internal
electrical insulation failure.
CUTTING SAFETY
WARNING: Inspect area to be cut.
Remove objects (rocks, broken glass, nails,
wire, string, etc.) which can be thrown or be-
come entangled in cutting head.
S Do not overreach or stand on unstable sup-
port. Keep firm footing and balance.
S Keep the cutting head below waist level. Do
not raise handles above your waist. Cutting
head can come dangerously close to your
body.
S Keep away from cutting head and spinning
line.
S Use unit properly. Use only for trimming,
scalping, and mowing. Do not force unit. It
will do the job better and with less risk of in-
jury at the rate for which it was designed.
S Use only in daylight or in good artificial light.
WARNING: All electrical repairs to
this unit, including housing, switch, motor,
locking sleeve assembly, wires, etc., must be
diagnosed and repaired by qualified service
personnel. Replacement parts for a double in-
sulated appliance must be recommended by
the manufacturer. A double insulated ap-
pliance is marked with the words “double in-
sulation” or “double insulated”. The symbol
(square within a square)
may also be
marked on the appliance. Failure to have the
unit repaired by qualified service personnel
can cause the double insulation construction
to become ineffective and result in serious
injury.

ATTACHING THE SHIELD
WARNING: The shield must be prop-
erly installed. The shield provides partial
protection from the risk of thrown objects to

line limiter blade (on underside of shield) is
sharp and can cut you.

age to unit (including motor failure) will result.
1. Align the installation arrow on the shield
with the installation arrow on the motor
housing (see illustration below).
2. Insert the shield onto the motor housing.
Ensure the cutting head remains free to
rotate and the line is not caught between
the shield and the motor housing.
4. Ensure locking sleeve assembly and
alignment decals appear as illustrated be-
low.
3. Twist the shield as illustrated until it snaps
securely into place. Make sure the shield
is assembled to the unit as shown in the
illustration below and in the KNOW
