INTRODUCTION
This product has many features for making its use more pleasant and enjoyable. Safety, performance, and dependability
have been given top priority in the design of this product making it easy to maintain and operate.
GENERAL SAFETY RULES
 Inspect the unit before each use for loose fasteners, fuel
leaks, etc. Replace any damaged parts before use.
 It has been reported that vibrations from hand-held tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness, and blanching of the fingers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking, and work practices
are all thought to contribute to the development of these
symptoms. It is presently unknown what, if any, vibrations
or extent of exposure may contribute to the condition.
There are measures that can be taken by the operator to
possibly reduce the effects of vibration:
a) Keep your body warm in cold weather. When operating
the unit wear gloves to keep your hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.
b) After each period of operation, exercise to
increase blood circulation.
c) Take frequent work breaks. Limit the amount of
exposure per day.
d) Keep the product well maintained, fasteners
tightened and worn parts replaced.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician about
these symptoms.
 Mix and store fuel in a container approved for gasoline.
 Mix fuel outdoors where there are no sparks or flames.
Wipe up any fuel spillage. Move 30 ft. away from refueling
site before starting engine.
 Stop the engine and allow to cool before refueling or
storing the unit.
 Allow the engine to cool; empty the fuel tank and secure
the unit from moving before transporting in a vehicle.
 Use only original manufacturer’s replacement parts. Failure
to do so may cause poor performance, possible injury,
and will void your warranty.
 Do not, under any circumstance, use any attachment or
accessory on this product, which was not provided with
the product, or identified as appropriate for use with this
product in the operator’s manual.
 Avoid dangerous environments. Do not use the attachment in damp or wet locations. Do not use in rain.
 Do not use on steps, a ladder, or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.
 Do not force the hedge trimmer. It will do the job better
and with less likelihood of a risk of injury at the rate for
which it was designed.
 Keep hands away from cutting area. Keep hands away
from blades. Do not reach underneath work or around
or over the blade while blade is rotating. Do not attempt
to remove cut material when blade is moving.
 Blade coasts after being turned off.

APPLICATIONS
You may use this product for the purposes listed below:
n Trimming and shaping hedges and shrubbery
FUELING AND REFUELING the trimmer
FUEL MIXTURE
This product is powered by a 2-cycle engine and requires premixing gasoline and 2-cycle lubricant. Pre-mix unleaded
Some conventional gasolines are blended with alcohol or an
ether compound. These gasolines are collectively referred
to as oxygenated fuels. To meet clean air standards, some
areas of the United States and Canada use oxygenated fuels
to help reduce emissions.
If using an oxygenated fuel, make sure it is unleaded and
meets the minimum octane rating requirements. Before using
an oxygenated fuel, try to confirm the fuel’s contents. Some
states/provinces require this information to be posted on the
pump. The following are the EPA approved percentages of
oxygenates:
Ethanol (ethyl or grain alcohol) 10% by volume. You
may use gasoline containing up to 10% ethanol by volume.
Gasoline containing ethanol may be marketed under the
OPERATION
name “Gasohol.” Do not use E85 fuel.
MTBE (methyl tertiary butyl ether) 15% by volume. You
may use gasoline containing up to 15% MTBE by volume.
Methanol (methyl or wood alcohol) 5% by volume. You
may use gasoline containing up to 5% methanol by volume
as long as it also contains cosolvents and corrosion inhibitors to protect the fuel system. Gasoline containing more
than 5% methanol by volume may cause starting and/or
performance problems. It may also damage metal, rubber,
and plastic parts of the product or your fuel system.
If you notice any undesirable operating symptoms, try another
service station or switch to another brand of gasoline.
NOTE: Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than
the percentages of oxygenates stated previously are not
covered under warranty.

CUTTING TIPS
a hedge so that it will be slightly narrower at the top. More
of the hedge will be exposed when shaped this way, and
it will be more uniform.
 Always wear gloves when using the hedge trimmer. When

trimming new growth, use a wide sweeping action, so that
the stems are fed directly into the cutting blade. Older
growth will have thicker stems and will be trimmed easiest
by using a sawing movement.
See Figure 6.
WARNING:
Always keep both hands on the hedge trimmer handles.
Never hold shrubs with one hand and operate hedge trimmer with the other. Failure to heed this warning can result
in serious injury.
OPERATING THE HEDGE TRIMMER
WARNING:
Clear the area to be cut before each use. Remove all
objects such as cords, lights, wire, or loose string which
can become entangled in the cutting blade and create a
risk of serious personal injury.
 Do not force the hedge trimmer through heavy shrubbery.
This can cause the blades to bind and slow down. If the
blades slow down, reduce the pace.
 Do not attempt to cut stems or twigs that are larger than
3/4 in. thick, or those obviously too large to feed into the
cutting blade. Use a non-powered hand saw or pruning
saw to trim large stems.
 If blades do become jammed, stop the engine, allow the
blades to stop, and remove the obstruction.
 If desired, you can use a string to help cut your hedge
level. Decide how high you want the hedge. Stretch a piece
of string along the hedge at the desired height. Trim the
hedge just above the guide line of string. Trim the side of

WARRANTY
The following California Air Resources Board (CARB) statement only applies to model numbers required to meet the CARB requirements.
TECHTRONIC INDUSTRIES NORTH AMERICA, INC., LIMITED WARRANTY STATEMENT FOR FEDERAL
AND CALIFORNIA EMISSION CONTROL SYSTEMS NON-ROAD AND SMALL OFF-ROAD ENGINES
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The U.S. Environmental Protection Agency (EPA), the California Air Resources Board
(CARB), and Techtronic Industries North America, Inc., are pleased to explain the
Emissions Control System Warranty on your 2008 model year non-road or small offroad engine. In California, new equipment that uses small off-road engines must be
designed, built, and equipped to meet the state’s stringent anti-smog standards. In
other states, new 2000 and later model year non-road engines must be designed,
built, and equipped at the time of sale to meet the U.S. EPA regulations for small
non-road engines. The non-road engine must be free from defects in materials and
workmanship which cause it to fail to conform with U.S. EPA standards for the first
two years of engine use from the date of sale to the ultimate purchaser. Techtronic
Industries North America, Inc., must warrant the emission control system on your
non-road or small off-road engine for the period of time listed above provided there
has been no abuse, neglect, or improper maintenance of your non-road or small
off-road engine.
Your emission control system may include parts such as the carburetor or fuel injection
system, the ignition system, catalytic converters, fuel tanks, valves, filters, clamps,
connectors, and other associated components. Also included may be hoses, belts
and connectors, and other emission-related assemblies.
Where a warrantable condition exists, Techtronic Industries North America, Inc., will
repair your non-road or small off-road engine at no cost to you, including diagnosis, parts, and labor performed at an authorized service center for RYOBI® brand
outdoor products.
Techtronic Industries North America, Inc., shall remedy warranty defects at any
authorized RYOBI® Authorized Service Center, including any distribution center
that may be franchised to service the subject engines. Any diagnostic work done
at a RYOBI® Authorized Service Center shall be free of charge to the owner if such
work determines that a warranted part is defective. Any manufacturer-approved or
equivalent replacement part may be used for any warranty maintenance or repairs
on emission-related parts, and must be provided free of charge to the owner if the
part is still under warranty. Techtronic Industries North America, Inc., is liable for
damages to other engine components caused by the failure of a warranted part
still under warranty.
Add-on or modified parts that are not exempted by the California Air Resource Board
may not be used. The use of any non-exempted add-on or modified parts will be
grounds for disallowing a warranty claim. Techtronic Industries North America, Inc.,
will not be liable to warrant failures of warranted parts caused by the use of a nonexempted add-on or modified part.
The California Air Resources Board’s Emission Warranty Parts List specifically defines
the emission-related warranted parts. (EPA’s regulations do not include a parts list,
but the EPA considers emission-related warranted parts to include all the parts listed
below.) Techtronic Industries North America, Inc., will provide any documents that
describe its warranty procedures or policies within five days upon request by the
California Air Resources Board.

OWNER’S WARRANTY RESPONSIBILITIES
(a) As the non-road or small off-road engine owner, you are responsible for
the performance of the required maintenance listed in your operator’s manual.
Techtronic Industries North America, Inc., recommends that you retain all receipts covering maintenance on your non-road or small off-road engine, but
Techtronic Industries North America, Inc., cannot deny warranty solely for the
lack of receipts or for your failure to ensure the performance of all scheduled
maintenance. Any replacement part or service that is equivalent in performance
and durability may be used in non-warranty maintenance or repairs, and shall
not reduce the warranty obligations of Techtronic Industries North America, Inc.
(b) As the non-road or small off-road engine owner, you should be aware, however,
that Techtronic Industries North America, Inc., may deny you warranty coverage if
your non-road or small off-road engine or a part has failed due to abuse, neglect,
improper maintenance, or unapproved modifications.
(c) You are responsible for presenting your non-road or small off-road engine to an
authorized service dealer as soon as a problem exists. The warranty repairs should
be completed in a reasonable amount of time, not to exceed 30 days.
If you have any questions regarding your warranty rights and responsibilities, you
should contact a Techtronic Industries North America, Inc., Customer Representative at 1-800-860-4050.
DEFECT WARRANTY COVERAGE REQUIREMENTS:
(a) The warranty period begins on the date the engine or equipment is delivered to
an ultimate purchaser.
(b) General Emissions Warranty Coverage. Techtronic Industries North America,
Inc., warrants to the ultimate purchaser and each subsequent purchaser that your
non-road or small off-road engine is designed, built, and equipped at the time of sale
to conform with all applicable regulations adopted by the California Air Resources
Board or the United States Environmental Protection Agency; and that it is free from
defects in materials and workmanship which cause the engine to fail to conform with
applicable regulations for a period of two years from the date the non-road or small
off-road engine is purchased by the initial purchaser.
(c) The warranty on emissions-related parts will be interpreted as follows: Any
warranted part that is not scheduled for replacement as required in the Emissions
Maintenance Schedule and Warranty Parts List set forth below is warranted for two
years. If any such part (including any part that is scheduled only for regular inspection)
fails during the period of warranty coverage, it will be repaired or replaced at any
RYOBI® Authorized Service Center at no charge. Any such part repaired or replaced
under warranty will be warranted for the remaining warranty period. A statement to
the effect of “repair or replace as necessary” would not reduce the period of warranty coverage. Any warranted part that is scheduled for replacement as required
maintenance in the Emissions Maintenance Schedule and Warranty Parts List is
warranted for the period of time prior to the first scheduled replacement point for
that part. Any such part repaired or replaced under warranty is warranted for the
remainder of the period prior to the first scheduled replacement point, and will be
repaired or replaced at any RYOBI® Authorized Service Center for no charge until
that replacement point is reached.
