OIL & FUEL INFORMATION
THIS ENGINE IS CERTIFIED TO OPERATE ON UNLEADED GAS ONLY.
NOTE: BE SURE TO READ THESE
INSTRUCTIONS CAREFULLY BEFORE
ATTEMPTING TO START OR OPERATE
THIS UNIT. Using old or improper oil or
fuel can cause engine damage. This type
of damage will void the engine warranty.
RECOMMENDED OIL TYPE
Using the proper type and weight of oil in the crankcase is
extremely important. Check the oil before each use and
change the oil regularly. Failure to use the correct oil, or
using dirty oil, can cause premature engine wear and fail-
ure.
Use high-quality SAE 30 weight oil of API (American
Petroleum Institute) service class SG, SF.
Fig. 15
ADDING OIL TO CRANKCASE - INITIAL
USE
Your unit is supplied with one bottle of oil, which contains
100 ml (3.4 fluid oz) of SAE 30 SF, SG oil (Fig. 14).
1. Open the bottle of oil.
Fig. 16
2. Install the funnel spout.
4. Reinstall oil fill plug / dipstick into the crankcase.
NOTE: Save the bottle and funnel spout for
future use.
NOTE: DO NOT ADD OIL TO THE FUEL.
Funnel Spout
100 ml
(3.4 oz)
Level
CHECKING THE OIL
The importance of checking and maintaining the proper oil
level in the crankcase cannot be overemphasized. Check
the oil BEFORE EACH USE as follows:
1. Make sure the engine is stopped, level (Fig. 16) and is
cool so the oil has had time to drain into the
crankcase.
Fig. 14
2. To keep dirt, grass clippings, etc. out of the engine,
clean the area around the oil fill plug / dipstick before
removing it.
3. Remove the oil fill plug / dipstick from the crankcase.
Pour the entire bottle of oil into the crankcase (Fig.
15). Make sure the engine is level (Fig. 16) when the oil
is poured into the crankcase.
3. Remove the oil fill plug / dipstick; wipe the oil off.
Reinsert it into the crankcase. Thread the oil fill plug /
dipstick into the crankcase.
4. Remove the oil fill plug / dipstick and check the oil
level. The oil level should be up to the top of the dip-
stick (Fig. 17).
5. If the level is low, add the oil to the top of the dipstick
(Fig. 17). Always check the level with the dipstick
before adding more oil.

OIL & FUEL INFORMATION (Continued)
RECOMMENDED FUEL TYPE
WARNING
Fuel is extremely flammable and its vapors can
explode if they are ignited. Always stop the
engine and allow it to cool before filling the fuel
tank. Do not smoke while filling the tank. Keep
sparks and open flames away from the area.
O-ring
Full (100 ml/3.4 oz)
Add Oil
Fill the fuel tank, using clean, fresh, unleaded gasoline.
NOTE: Alcohol blended fuel absorbs moisture
(water). As little as 1% moisture in the
fuel can cause fuel to separate and form
acids when stored.
Fig. 17
CHANGING THE OIL
For a new engine, change the oil after the first 10 hours of
operation. Thereafter, change the oil after every 25 hours
or before storing the unit for an extended period of time.
If this type of fuel must be used, use
fresh fuel (less than 60 days old).
DEFINITION OF BLENDED FUELS
Change the oil while the engine is still warm. The oil will
flow freely and carry away more impurities.
Today's fuels are often a blend of gasoline and one or
more oxygenates such as ethanol, methanol or MTBE
(ether).
Change the oil as follows:
1. Remove the oil fill plug / dipstick.
USE OF BLENDED FUELS
2. Pour the oil into a container by tipping the trimmer in
a vertical position (Fig. 18). Be sure to allow ample
time for complete drainage. Dispose of oil properly.
If you choose to use a blended fuel or its use is unavoid-
able, the following precautions are recommended.
1. Always use fresh fuel.
2. Use the special additive GASOHOL GAS TREAT-
®
MENT (by Gold Eagle) or an equivalent to inhibit
corrosion.
3. Drain tank and run engine dry before storing the
unit.
USE OF FUEL ADDITIVES
®
The use of fuel additive such as STA-BIL Gas Stabilizer
or an equivalent, will inhibit corrosion and minimize the for-
mation of gum deposit. Add (23 ml) 0.8 oz per gallon of
fuel per instructions on container. NEVER add fuel addi-
tives directly to the unit's fuel tank. Using a fuel additive
can keep fuel fresh for up to six (6) months.
Fig. 18
3. Fill the crankcase, with new oil of the proper type, to
the top of the dipstick. Use the bottle saved from the
initial use.
4. Reinstall the oil fill plug / dipstick and tighten securely.
NOTE: Make sure the O-ring is in place on the
oil fill plug when checking and changing
the oil.
NOTE: To prevent extensive engine wear or
damage, always maintain the proper oil
level in the crankcase. Never operate the
engine with oil level below the bottom of
the dipstick.

OPERATING INSTRUCTIONS
ADJUSTING THE TRIMMING LINE
USING THE BRUSH BLADE
LENGTH
1. Always maintain the proper stance when using the
brush blade (Fig. 25).
Your trimmer is equipped with a bump head that allows
the operator to release more trimming line without stop-
ping the engine. To release additional line, lightly tap the
trimming head on the ground (Fig. 23) while operating the
trimmer at high speed.
Sharpening the Brush Blade
WARNING
Do not sharpen the brush blade. Sharpening
the blade can cause the blade tip to break off
while in use. This can result in severe
personal injury to yourself or others.
The brush blade is designed with a second set of teeth,
which can be used by removing the blade, turning it
upside down, and reinstalling it.
If a crack is noticed, install a new blade from your
authorized service dealer.
Fig. 23
NOTE: Always keep the trimming line fully
extended. Line release becomes more
difficult as cutting line becomes shorter.
Each time the head is bumped, about 25.4 mm (1 in) of
trimming line is released. A blade in the line guard will cut
the line to the proper length if excess line is released.
For best results, tap the head on bare ground or hard soil.
If line release is attempted in tall grass, the engine may
stall.
DECORATIVE TRIMMING
Decorative trimming is accomplished by removing all
vegetation around trees, posts, fences, etc. Use a
30-degree angle when trimming with this method (Fig. 24).
Fig. 25
NOTE: Do not use the brush blade for edging.
Use the LE720r edger attachment.
WARNING
Keep the J-handle between the operator and
cutting head at all times.

CARBURETOR ADJUSTMENT
Throttle
Lever
Idle Speed
Screw
This unit is equipped with a diaphragm-type carburetor
that has been carefully calibrated at the factory. In most
cases, no further adjustment will be required.
NOTE: To meet the 1995 California emission
regulations, the carburetor has adjust-
ment needle limiter caps to restrict the
amount of adjustment.
High Speed
Mixture Needle
The condition of the air filter is important to the operation
of the trimmer. A dirty air filter will restrict the air flow,
which upsets the fuel-air mixture in the carburetor. The
resulting symptoms are often mistaken for an out-of-
adjustment carburetor. Therefore, check the condition of
the air filter before adjusting the carburetor. Refer to
Air Filter Maintenance.
Idle Speed
Mixture Needle
If the following conditions are experienced, it may be nec-
essary to adjust the carburetor:
Fig. 40
•
•
•
The engine will not idle
The engine hesitates or stalls on acceleration
The loss of engine power that is not corrected by
cleaning the air filter, muffler, spark arrester screen or
adjusting the valve clearance
4. Start the engine and let it run for three (3) to five (5)
minutes with the throttle trigger fully squeezed.
•
The engine operates in an erratic or fuel rich condition
5. Release the throttle trigger and let the engine idle. If
the engine stops, turn the idle speed screw (Fig. 40)
n (clockwise) 1/8 turn at a time (as required) until
the engine idles.
The carburetor has three basic adjustments: the idle
speed, idle speed mixture and high speed mixture.
NOTE: The string guard and line spool must be
installed and the cutting line extended to
its full cutting length when making
carburetor adjustments.
6. Final High Speed Mixture Needle Adjustment:
a. While squeezing the throttle trigger fully, set the
high speed mixture needle at the optimum setting
(Fig. 41). See “Definition of Optimum Setting” on
page 21.

CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
MANUFACTURER'S WARRANTY COVERAGE:
The California Air Resources Board and Ryobi Outdoor Products (ROP), are 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.
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.
•
•
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.
Where a warrantable condition exists, ROP will repair your lawn and garden equipment
engine at no cost to you including diagnosis, parts and labor.
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 nec-
essary" is warranted for the warranty period. Any 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:
•
As the lawn and garden equipment engine owner, you are responsible for the perform-
ance 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 manufacturer is liable for damages to other engine components caused by the fail-
ure of a warranted part still under warranty.
Failures caused by abuse, neglect or improper maintenance are not covered
under warranty.
•
•
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.
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.
You are responsible for presenting your lawn and garden equipment engine to an 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.
•
•
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.
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 durabili-
ty may be used in non-warranty maintenance or repair and will not reduce the warranty
obligations of the manufacturer.
If you have any questions regarding your warranty rights and responsibilities, you should
call 1-800-345-8746.
•
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.
