WORK AREA SAFETY
1. ALWAYS avoid dangerous conditions. DO NOT use in wet or damp areas or
expose to rain.
2. DO NOT operate in the presence of flammable liquids, gases, or dust. Electric
tools create sparks which may ignite dust or fumes.
3. ALWAYS keep bystanders and visitors at a safe distance while operating
a trimmer. NEVER allow children near the tool. Flying objects can injure anyone
in the area.
4. CHILDPROOF your tools with padlocks and master switches. Lock tools away when
not in use. This trimmer is not a toy.
5. DO NOT use trimmer at night. ALWAYS make sure you have adequate lighting.
6. BEFORE using the trimmer, remove any stones, sticks, debris or objects that could
be entangled in or thrown by the trimmer.
1. KNOW your tool. Read the operator’s manual carefully. Learn the electric trimmer’s
applications and limitations, as well as the specific potential hazards related to this tool.
2. STAY ALERT, watch what you are doing and use common sense when operating this tool.
3. DO NOT use tool while tired or under the influence of drugs, alcohol or medication.
A moment of inattention while operating this tool may result in serious personal injury.
4. DRESS properly. Wear rubber gloves and substantial rubber soled footwear when
working outdoors. DO NOT operate lawn and garden tools when barefoot or wearing
open sandals. Wear long pants and long sleeves to protect your legs and arms.
Trimmers can pick up objects such as rocks and send them flying at fast speeds.
DO NOT wear loose clothing or jewelry. Keep your hair, clothing, and gloves away
from moving parts. Loose clothing or long hair can be caught in moving parts.
5. USE SAFETY EQUIPMENT. Always wear safety goggles or safety glasses with side
shields or full face shield, proper work shoes with rubber non-slip soles, heavy-duty
non-slip rubber gloves and dust mask or respirator and hearing protection. Hard
hat should be used for appropriate conditions.
6. DO NOT overreach. Keep proper footing and balance at all times. Proper footing and
balance enables better control of the tool in unexpected situations.
1. DO NOT use the tool if switch does not turn it “On” or “Off”. Any tool that cannot be
controlled with the switch is dangerous and must be repaired.
2. DISCONNECT the plug from the power source before making any adjustments,
changing cutting line, or storing the tool. Such preventive safety measures reduce the
risk of starting the tool accidentally.
3. STORE idle tools out of the reach of children and other untrained persons. Children
MUST NOT operate the tool. Tools are dangerous in the hands of untrained users.
4. MAINTAIN tools with care. ALWAYS keep cutting tools clean and in good working order.
5. CHECK for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the tool's operation. If damaged, have the tool serviced
before using. Many accidents are caused by poorly maintained tools.
6. USE ONLY cutting line that is recommended for this trimmer. Cutting line that may be
suitable for one trimmer may become hazardous when used on another trimmer.
1. Double insulated tools are equipped with a polarized
plug (one blade is wider than the other). This plug will
fit in a polarized outlet only one way. If the plug does
not fit fully in the outlet, reverse the plug. If it still does
not fit, contact a qualified electrician to install a polarized
outlet. Do not change or alter the plug in any way.
2. Double insulation eliminates the need for the
three-wire grounded power cord and grounded power
supply system. Applicable only to Class II (double insulated) tools. This trimmer is a double insulated tool.

EXTENSION CORDS
Use a proper extension cord. ONLY use cords listed by Underwriters Laboratories (UL).
Other extension cords can cause a drop in line voltage, resulting in a loss of power
and overheating of tool.
For this tool an AWG (American Wire Gauge) size of a least 14-gauge is recommended
for an extension cord of 25- ft. or less in length. Use 12-gauge for an extension cord
of 50-ft. Extension cords 100-ft. or longer are not recommended.
Remember, a smaller wire gauge size has greater capacity than a larger number
(14-gauge wire has more capacity than 16-gauge wire; 12-gauge wire has more capacity
than 14-gauge). When in doubt use the smaller number.
When operating a power tool outdoors, use an outdoor extension cord marked “W-A” or “W”.
These cords are rated for outdoor use and reduce the risk of electric shock.
!
CAUTION:
Keep the extension cord clear of the work area. Position the
cord so that it will not get caught on bushes, hedges, tree trunks, lawnmowers
or other obstructions while you are working with the trimmer.
CAUTION:
This trimmer has a 12-in. Pigtail Power Cord that must be
plugged into a proper extension cord (see below).
!
WARNING:
Double insulation DOES NOT take the place of normal safety
precautions when operating this tool.
!
WARNING:
GFCI (Ground Fault Circuit Interrupter) protection should be
provided on all circuits or outlets to be used for electric lawn and garden power
tools. Receptacles are available having built-in GFCI protection and should be
used for this measure of protection.
!
ELECTRICAL SAFETY cont.
3. BEFORE plugging in the tool, BE SURE that the outlet voltage supplied is within
the voltage marked on the tool’s data plate. DO NOT use “AC only” rated tools with a DC
power supply.
4. DO NOT expose tools to rain or wet conditions or use electric tools in wet or damp
locations. Water entering an electric tool will increase the risk of electric shock.
5. If operating an electric tool in damp locations is unavoidable, ALWAYS USE a
Ground Fault Circuit Interrupter to supply power to your tool. ALWAYS WEAR
electrician’s rubber gloves and footwear in damp conditions.
6. When operating a power tool outside, ALWAYS use an outdoor extension cord marked
“W-A” or “W”. these cords are rated for outdoor use and reduce the risk of electric shock.
7. INSPECT tool cords for damage. Have damaged tool cords repaired at a Sears Service
Center. BE SURE to stay constantly aware of the cord location and keep it well away
from the spinning cutting lines.
8. DO NOT abuse the cord. NEVER use the cord to carry the tool by or to pull the plug
from the outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged cords increase the risk of electric shock.
WARNING:
Check extension cords before each use. If damaged replace
immediately. Never use tool with a damaged cord since touching the damaged
area could cause electrical shock, resulting in serious injury.
