SAvoid dangerous environments. Do not use in unventilated areas or where dust or explo- sive vapors can build up.
STo reduce the risk of electrical shock, use ex- tension cords specifically marked as suitable for outdoor appliances. The electrical rating of the cord must not be less than the rating of the unit. The cord must be marked with the suffix “W-A” (in Canada, “W”). Make sure your ex- tension cord is in good condition. Inspect ex- tension cord before use and replace if dam- aged. An undersized extension cord will cause a drop in line voltage resulting in loss of power and overheating. If in doubt, use the
next heavier gauge. The smaller the gauge number, the heavier the cord.
SDo not use multiple cords.
SThe powerhead may have a polarized plug (one blade is wider than the other); if so, it will require the use of a polarized extension cord. The appliance plug will fit into a polarized ex- tension cord only one way. If the plug does not fit fully into the extension cord, reverse the plug. If the plug still does not fit, obtain a cor- rect polarized extension cord. A polarized ex- tension cord will require the use of a polarized wall outlet. This plug will fit into the polarized wall outlet only one way. If plug does not fit fully into the wall outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper wall outlet. Do not change
the equipment plug, extension cord recep- tacle, or extension cord plug in any way.
SDo not attempt to repair unit. Inspect the insu- lation and connectors on the powerhead and extension cord before each use. If there is
any damage, do not use until damage is re- paired by your authorized service dealer.
SDo not pull or carry by cord; do not use cord as a handle, close a door on cord, or pull cord around sharp edges or corners. Keep cord away from heated surfaces. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
SDo not use the powerhead if the switch does not turn the unit on and off properly. Have the unit repaired by your authorized service deal-
er.
SKeep the extension cord clear of operator and obstacles at all times. Do not expose cords to heat, oil, water, or sharp edges.
SAvoid any body contact with any grounded conductor, such as metal fences, or pipes, to
avoid the possibility of electric shock. Don’t handle plug or unit with wet hands.
SDo not use with damaged cord or plug. If pow- erhead is not working as it should, has been dropped, damaged, left outdoors, or dropped
into water, return it to your authorized service for repair.
S Ground Fault Circuit Interrupter (GFCI) protection should be provided on the circuit or outlet to be used for the powerhead. Recep- tacles are available having built-in GFCI protection and may be used for this measure of safety.
Your powerhead should be double insulated to help protect against electric shock. Double insulation construction consists of two sepa- rate “layers” of electrical insulation instead of grounding. Tools and appliances built with a double insulation system are not intended to be grounded. Safety precautions must be ob- served when operating any electrical tool. The double insulation system only provides added protection against injury resulting from an internal electrical insulation failure.
WARNING: All repairs to an electric powerhead, including housing, switch, motor, etc., must be diagnosed and repaired by qual- ified service personnel. Replacement parts for a double insulated appliance must be iden- tical to the parts they replace. A double insu- lated appliance is marked with the words “double insulation” or “double insulated”. The symbol 
(square within a square) may also be marked on the appliance. Failure to have the unit repaired by your authorized service dealer can cause the double insulation con- struction to become ineffective and result in serious injury.
UNIT/MAINTENANCE SAFETY
WARNING: Disconnect powerhead spark plug (or disconnect powerhead from power source) before performing mainte- nance.
SInspect entire unit before each use. Replace damaged parts. Check for fuel leaks. Make sure all fasteners are in place and securely
fastened.
SMaintain unit according to recommended pro-
cedures.
S Throw away blades that are bent, warped, cracked, broken, or damaged in any other way. Replace parts that are cracked, chipped, or damaged before using the unit.
SUse only recommended Weed Eater→ parts
and accessories. Never use wire, wire rope, string, flailing devices, etc.
SBe sure blade stops turning when engine idles (see CARBURETOR ADJUST- MENTS section of powerhead manual).
SRemove the blade before making carburetor adjustments. Hold the unit by hand. Do not
make carburetor adjustments from the blade side of the unit.
SKeep others away when making carburetor adjustments.
SNever start the unit with the clutch housing re- moved. The clutch can fly off and cause seri- ous injury.
SHave all maintenance and service not ex- plained in this manual performed by an autho-
rized service dealer.
SIf blade strikes a foreign object, follow these steps: stop unit and disconnect spark plug wire (or disconnect from power source), in- spect for damage, and repair any damage be- fore resuming operation of the unit.
