• Use only genuine original equipment manufacturer replacement
parts and accessories as specified in this manual. These are
available from your authorized service dealer. Use of any nonoriginal parts or accessories could lead to serious injury to the
user, or damage to the unit, and void your warranty.
• Stay alert – Do not operate this unit when tired, ill, or under
the influence of alcohol, drugs, or medication.
• Keep Children Away – Clear the area to be cut before each use.
Remove rocks, broken glass, nails, wire, string and other objects
which may be thrown or become entangled in the cutting attachment. Clear the area of children, bystanders and pets; keep them
outside a 50-foot (15 m.) radius, at a minimum. Even then, they
are still at risk from thrown objects. Encourage bystanders to wear
eye protection. If you are approached, stop the unit immediately.
• Children and teens under the age of 15 must not use the unit,
except for teens guided by an adult.
• Do not allow unit to be used as a toy. Close attention is
necessary when used by or near children.
• Do not leave appliance when plugged in. Unplug from outlet
when not in use.
• Do not use with damaged cord or plug. If appliance is not
working as it should, has been damaged, left outdoors or
dropped into water, return it to a service center.
• Do not abuse the power cord. Never carry the unit by the cord, use
cord as a handle, close a door on cord, or pull cord around sharp
edges or corners. Keep cord away from heat surfaces and oil.
• Do not yank or pull the cord to disconnect from receptacle. To
unplug, grasp the plug, not the cord.
• Avoid Dangerous Environment to reduce the risk of electric shock,
never operate your unit on wet surfaces or damp locations.
• Do not expose or use in rain. Moisture can increase risk of shock.
• Do not handle the plug or the unit with wet hands.
• Do not put any object into openings. Do not use with any
opening blocked - keep free of dust, lint, hair and anything
that may reduce airflow.
• Dress properly – Do not wear loose clothing or jewelry, they
can be caught in moving parts. Wear protective hair covering
to contain long hair. Do not wear short pants, sandals or go
barefoot. Use of rubber gloves and substantial footwear is
recommended when working outdoors.
• Use extra care when cleaning on stairs.
• Wear safety glasses or goggles that are marked as meeting ANSI
Z87.1-1989 standards. Safety glasses are available at your
Craftsman retailer or local hardware store. Also wear ear/hearing
protection when operating this unit. Wear a face or dust mask if
the operation is dusty. Long sleeve shirts are recommended.
• Use the right tool. Only use this tool for its intended purpose.
• Turn off all controls before unplugging.
• Store the unit indoors. Lock up the unit to prevent unauthorized
use or damage and to keep out of the reach of children.
ELECTRICAL SAFETY WARNINGS
• Since the tool is double-insulated, a 2-wire extension cord (an
extension cord without a ground) may be used. A 3-wire
extension cord (an extension cord with a ground) that uses a
NEMA-type connector (parallel blade, U ground) is recommended. Extension cords are available from your local retailer. Use
only round-jacketed extension cords approved for outdoor use.
•
This tool is double-insulated. Repair or replace damaged cords.
• To reduce the risk of electrical shock, this appliance has a
polarized plug (one blade is wider than the other) and will require
the use of a polarized extension cord. The appliance plug will fit
into a polarized extension 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 correct polarized extension cord. A
polarized extension cord will require the use of a polarized wall
outlet. This plug will fit into the polarized wall outlet only one
way. If the plug does not fit fully into the wall outlet, reverse the
plug. If the plug still does not fit, contact a qualified electrician to
install the proper wall outlet. Do not change the equipment plug,
extension cord receptacle, or extension cord plug in any way.
• In a double-insulated appliance, two systems of insulation are
provided instead of grounding. No grounding means is
provided on a double-insulated appliance, nor should a means
for grounding be added to the appliance. Servicing a doubleinsulated appliance requires extreme care and knowledge of
the system and should be done only by qualified service
personnel. Replacement parts for a double-insulated appliance
must be identical to the parts they replace.
*The wire size (AWG) for appliances using 12 to 16 amps is
14 AWG for 25 feet, 12 AWG for 50 feet, and not
recommended for 100 or 150 feet.
• CORD SETS: Make sure your cord set is in good condition, with
a cord that is heavy enough to carry the current that your unit will
draw. An undersized cord set will cause a drop in line voltage
resulting in a loss of power, as well as overheating. The table
shown above illustrates the correct size to use depending on the

OPERATING TIPS WHEN USING TRIMMER/BLOWER
ATTACHMENT
• To reduce the risk of hearing loss associated with sound
level(s), the use of hearing protection is required.
• Operate power equipment only at reasonable hours—not
early in the morning or late at night when people might be
disturbed. Comply with time listed in local ordinance. Usual
recommendations are 9:00 am to 5:00 pm, Mon. through Sat.
• To reduce noise levels, limit the number of pieces of
equipment used at any one time.
• To reduce noise levels, operate power blowers at the
lowest possible speed to do the job.
• Use rakes and brooms to loosen debris before blowing.
• Conserve water by using power blowers instead of hoses for
many lawn and garden applications, including areas such as
gutters, screens, patios, grills, porches, and gardens.
• Watch out for children, pets, open windows, or freshly
washed cars, and blow debris away.
• After using blowers and other equipment, CLEAN UP!
Dispose of debris in trash receptacles.
TIPS FOR BEST TRIMMING RESULTS
• Keep the cutting attachment parallel to the ground.
• Cut from left to right whenever possible. Cutting to the right
improves the unit's cutting efficiency. Clippings are thrown
away from the operator.
• Trim only when grass and weeds are dry.
• The life of your cutting line is dependent upon:
- Following the trimming tips
- What vegetation is being cut
- Where vegetation is being cut
WARNING: To prevent serious injury to yourself or
others, or possible damage to property, never point
the blower in the direction of people or pets, or in
the direction of windows. Always direct the blowing
debris away from people, animals, and windows.
