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:

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.
