OIL AND FUEL INFORMATION
Old or improperly mixed fuel are usually
USE OF FUEL ADDITIVES
the main reasons for the unit not running
properly. Be sure to use fresh, clean fuel and
follow the instructions carefully for the proper
fuel/oil mixture.
The use of fuel additive, such as STA-BIL®
Gas Stabilizer or an equivalent, will inhibit
corrosion and minimize the formation of gum
deposits. Add 0.8 oz (23 ml) per gallon of fuel
per instructions on container. NEVER add fuel
additives directly to the unit's fuel tank. Using
a fuel additive can keep fuel fresh for up to six
(6) months.
NOTE: Alcohol-blended fuel absorbs moisture
(water). As little as 1% moisture in the
fuel can cause fuel and oil to separate
and form acids when stored. If this
type of fuel must be used, use fresh
fuel (less than 60 days old), and mix
according to the mixing instructions.
CAUTION: For proper engine
operation and maximum reliability,
pay strict attention to the oil and
fuel mixing instructions on the
2-cycle oil container. Use a 32:1
fuel/oil ratio. Use 2-cycle oil. Using
improperly mixed fuel can severely
damage the engine.
DEFINITION OF BLENDED FUELS
Today's fuels are often a blend of gasoline
and one or more oxygenates such as ethanol,
methanol or MTBE (ether).
OIL AND FUEL MIXING INSTRUCTIONS
Thoroughly mix the proper ratio of 2-cycle
engine oil with unleaded gasoline in a
separate fuel can, 32:1. Do not mix them
directly in the engine fuel tank. See the table
below for specific gas and oil mixing ratios.
USE OF BLENDED FUELS
If you choose to use a blended fuel or its use
is unavoidable, the following precautions are
recommended.
1. Always use fresh fuel mix per your
operator's manual.
2. Use the special additive STA-BIL® or
an equivalent.
+
3. Always agitate the fuel mix before fueling
the unit.
4. Drain the tank and run the engine dry
before storing the unit.

OPERATING INSTRUCTIONS
DECORATIVE TRIMMING
ADJUSTING TRIMMING LINE LENGTH
Decorative trimming is accomplished by
removing all vegetation around trees, posts,
fences, etc.
Rotate the entire unit so that the cutting head
is at a 30° angle to the ground (Fig. 12).
Your unit is equipped with a cutting head that
allows the operator to release more trimming
line without stopping the engine. To release
additional line, lightly tap the cutting head on
the ground (Fig. 11) while operating the unit at
high speed.
NOTE: Always keep the trimming line fully
extended. Line release becomes more
difficult as cutting line becomes shorter.
Fig. 12
CAUTION: Do not remove or alter
the line cutting blade assembly.
Excessive line length will cause
clutch to overheat and may result
in serious personal injury.
Fig. 11
Each time the head is bumped, about 1 inch
(25.4 mm) of trimming line is released. A blade
in the string guard will cut the line to the proper
length if excess line is released.
EDGING
For best results, tap the head on bare ground
or hard soil. If line release is attempted in tall
grass, the engine may stall.
For edging with the trimming head attachment,
locate and lock the release button into the 90°
edging hole or 180° edging hole in the Click-
Link system (Fig. 10).

Correct air gap is 0.025 in. (0.655 mm). Remove
plug after every 50 hours of operation and check
its condition.
1. Drain all fuel from the fuel tank and drain
into a container with the same 2-cycle fuel
mixture. Do not use fuel that has been
stored for more than 60 days. Dispose
of the old fuel/oil mix in a safe manner and
use a fresh mix.
1. Stop the engine and allow it to cool. Pull the
wire off of the spark plug.
2. Clean around the spark plug and remove it
from the cylinder head. Use a 5/8" socket to
remove the plug.
2. Start the engine and allow it to run until it
stalls. This ensures that all fuel has been
drained from the carburetor.
CAUTION: Replace a cracked, fouled
or dirty spark plug. Do not sand blast,
scrape, or clean electrodes because
the engine could be damaged by grit
entering the cylinder.
3. Allow the engine to cool. Remove the spark
plug and put approximately 1 oz (30 ml) of
any high quality motor oil or 2-cycle oil into
the cylinder. Pull the starter rope slowly to
distribute the oil. Reinstall the spark plug.
3. Set the air gap at 0.025 in. (0.655 mm) using
a wire feeler gauge (Fig. 30). Install a correctly
gapped spark plug into the cylinder head.
Torque to 110-120 in•lb (12.3-13.5 N•m).
4. Thoroughly clean the unit and inspect for any
loose or damaged parts. Repair or replace
damaged parts and tighten loose screws, nuts
or bolts. The unit is now ready for storage.
5. To prevent unauthorized use or damage, lock up
and store the unit in a dry, well-ventilated area.
NOTE: Remove the spark plug and drain all of
the oil from the cylinder before attempting
to start the trimmer after storage.

any maintenance on it.
Use a small brush to clean off the outside of the

housing or handle. They can be damaged by
household cleaners that contain aromatic oils
such as pine and lemon, and by solvents such as
kerosene. Wipe off any moisture with a soft cloth.

CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board and Ryobi
MANUFACTURER'S WARRANTY COVERAGE:
Outdoor Products (ROP), is pleased to explain
the emission control system warranty on your
1995 and later lawn and garden equipment
engine. In California, new lawn and garden
equipment engines must be designed, built
and equipped to meet the State's stringent
anti-smog standards. ROP must warrant the
emission control system on your lawn and
garden equipment engine for the periods of
time listed below provided there has been no
abuse, neglect or improper maintenance of
your lawn and garden equipment engine.
•
•
The warranty period begins on the date the
engine or equipment is delivered to the retail
purchaser.
The manufacturer warrants to the initial owner
and each subsequent purchaser, that the
engine is free from defects in material and
workmanship which cause the failure of a
warranted part for a period of two years.
•
•
Repair or replacement of warranted part will
be performed at no charge to the owner at
an Authorized Ryobi Service Center. For the
nearest location, please contact Ryobi at:
1-800-345-8746.
Your emission control system may include parts
such as the carburetor or fuel injection system,
the ignition system, and catalytic converter. Also
included may be hoses, belts, connectors and
other emission-related assemblies.
Any warranted part which is not scheduled for
replacement, as required maintenance which
is scheduled only for regular inspection to the
effect of "Repair or replace as necessary" is
warranted for the warranty period. Any
Where a warrantable condition exists, ROP will
repair your lawn and garden equipment engine
at no cost to you including diagnosis, parts
and labor.
warranted part which is scheduled for
replacement as required maintenance will be
warranted for the period of time up to the first
scheduled replacement point for that part.
The 1995 and later utility and lawn and garden
equipment engines are warranted for two years.
If any emission-related part on your engine is
defective, the part will be repaired or replaced
by ROP.
•
•
The owner will not be charged for diagnostic
labor which leads to the determination that a
warranted part is defective, if the diagnostic
work is performed at an Authorized Ryobi
Service Center.
OWNER'S WARRANTY RESPONSIBILITIES:
The manufacturer is liable for damages to
other engine components caused by the
failure of a warranted part still under warranty.
•
As the lawn and garden equipment engine
owner, you are responsible for the
•
•
Failures caused by abuse, neglect or improper
maintenance are not covered under warranty.
performance of the required maintenance
listed in your operator's manual. ROP
recommends that you retain all receipts
covering maintenance on your lawn and
garden equipment engine, but ROP cannot
deny warranty solely for the lack of receipts
or for your failure to ensure the performance
of all scheduled maintenance.
The use of add-on or modified parts can be
grounds for disallowing a warranty claim. The
manufacturer is not liable to cover failures or
warranted parts caused by the use of add-on
or modified parts.
•
•
In order to file a claim, go to your nearest
Authorized Ryobi Service Center. Warranty
services or repairs will be provided at all
Authorized Ryobi Service Centers.
•
•
As the lawn and garden equipment engine
owner, you should however be aware that
ROP may deny you warranty coverage if your
lawn and garden equipment engine or a part
has failed due to abuse, neglect, improper
maintenance or unapproved modifications.
Any manufacturer approved replacement part
may be used in the performance of any
warranty maintenance or repair of emission
related parts and will be provided without
charge to the owner. Any replacement part
that is equivalent in performance or durability
may be used in non-warranty maintenance or
repair and will not reduce the warranty
obligations of the manufacturer.
You are responsible for presenting your lawn
and garden equipment engine to a Ryobi
Authorized Service Center as soon as a
problem exists. The warranty repairs should
be completed in a reasonable amount of time,
not to exceed 30 days.
•
The following components are included in the
emission related warranty of the engine, air
filter, carburetor, primer, fuel lines, fuel pick
up/fuel filter, ignition module, spark plug and
muffler.
If you have any questions regarding your
warranty rights and responsibilities, you
should call 1-800-345-8746.
