Safety Warnings and Precautions
WARNING: When using product, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.
Read all instructions before using this product!
1. Keep work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use machines or power tools in damp or wet
locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically powered
tools in the presence of flammable gases or liquids.
3. Keep children away. Children must never be allowed in the work area. Do not let them
handle machines, tools, or extension cords. Do not let them use the Trimmer, machines or
tools.
4. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit rust.
Always lock up tools and keep out of reach of children.
5. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the
work of a larger industrial tool. There are certain applications for which this tool was designed. It
will do the job better and more safely at the rate for which it was intended. Do not modify this
tool and do not use this tool for a purpose for which it was not intended.
6. Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving parts.
Protective, electrically non-conductive clothes and non-skid footwear are recommended when
working. Wear restrictive hair covering to contain long hair.
#47944 Page 2
7. Use eye and ear protection. Always wear ANSI approved impact safety goggles. Wear a full
face shield if you are producing metal filings or wood chips. Wear an ANSI approved dust mask
or respirator when working around metal, wood, and chemical dusts and mists.
8. Do not overreach. Keep proper footing and balance at all times. Do not reach over or across
running machines.
9. Maintain tools with care. Keep tools sharp and clean for better and safer performance.
Follow instructions for lubricating and changing accessories. Inspect tool cords periodically and,
if damaged, have them repaired by an authorized technician. The handles must be kept clean,
dry, and free from oil and grease at all times.
10. Disconnect power. Unplug tool when not in use.
11. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are
removed from the tool or machine work surface before plugging it in.
12. Avoid unintentional starting. Be sure the switch is in the Off position when not in use and
before plugging in. Do not carry any tool with your finger on the trigger, whether it is plugged in
or not.
13. Stay alert. Watch what you are doing; use common sense. Do not operate any tool when you
are tired.
14. Check for damaged parts. Before using any tool, any part that appears damaged should be
carefully checked to determine that it will operate properly and perform its intended function.
Check for alignment and binding of moving parts; any broken parts or mounting fixtures; and
any other condition that may affect proper operation. Any part that is damaged should be
properly repaired or replaced by a qualified technician. Do not use the tool if any switch does
not turn On and Off properly.
15. Guard against electric shock. Prevent body contact with grounded surfaces such as pipes,
radiators, ranges, and refrigerator enclosures.
16. Replacement parts and accessories. When servicing, use only identical replacement parts.
Use of any other parts will void the warranty. Only use accessories intended for use with this
tool. Approved accessories are available from Harbor Freight Tools.
17. Do not operate tool if under the influence of alcohol or drugs. Read warning labels on
prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there
is any doubt, do not operate the tool.
18. Use proper size and type extension cord. If an extension cord is required, it must be of the
proper size and type to supply the correct current to the tool without heating up. Otherwise, the
extension cord could melt and catch fire, or cause electrical damage to the tool. This tool
requires use of an extension cord of 0 to 10 amps capability (up to 50 feet), with wire size rated
at 18 AWG. Longer extension cords require larger size wire. If you are using the tool outdoors,
use an extension cord rated for outdoor use. (signified by “WA” on the jacket).
19. Maintenance. For your safety, service and maintenance should be performed regularly by a
qualified technician.
20. Make certain area is clear of rocks and debris before starting the Electric Grass
Trimmer.
21. Do not start the Trimmer while it is laying down or upside down.
22. Make certain that the Guard is always between you and the Nylon Line.
23. Never stop the Nylon Line with your hands. Always let it come to a complete stop
before handling or doing any maintenance.
#47944 Page 3
Note: Performance of this tool (if powered by line voltage) may vary depending on
variations in local line voltage. Extension cord usage may also affect tool
performance.
24. Make certain that the power cord is kept clear of the Nylon Line, failure to do so may
result in the power cord being cut, resulting in serious damage and injury.
Warning: The warnings, cautions, and instructions discussed in this instruction
manual cannot cover all possible conditions and situations that may
occur. It must be understood by the operator that common sense and
caution are factors which cannot be built into this product, but must be
supplied by the operator.
Warning: This product contains or produces a chemical known to the State of
California to cause cancer and birth defects (or other reproductive
harm).
(California Health & Safety Code 25249.5 et seq.)
VOLTAGE WARNING
Before connecting the tool to a power source receptacle be sure the voltage supplied is about the
same as that specified on the nameplate of the tool. If one says 120V and the other says 110V
then there will be no complications. Never try to plug a 110V tool into a 220V outlet, or the other
way around. The plug and outlet have completely different shapes. This is because a power source
with a voltage greater than that spedified on the tool can result in a serious injury to the user-as well
as damage to the tool. If in doubt, do not plug in the tool.
Your tool is double insulated and has a two-prong plug. you may use either a two or three prong
extension cord. Only use rounded jacket extension cords. If you plan on indoor use, you may also
us an outdoor rated cord. Extension cords rated for outdoor use have the letters “WA” on the cord
jacket.
#47944 Page 4
Do not modify your plug in any way. If you have any doubt, call a qualified electrician.
Warning: People with pacemakers should consult with their physician before using this
product; operation of equipment in close proximity to a heart pacemaker could cause
interference or failure of the pacemaker.
