OIL AND FUEL INFORMATION  
RECOMMENDED FUEL TYPE  
FUELING UNIT  
Old fuel is the primary reason for the unit not  
WARNING: Gasoline is extremely flammable  
and its vapors can explode if ignited. To  
avoid serious personal injury, 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

running properly. Be sure to use fresh, clean,  
unleaded Gasoline.  
NOTE: This is a four cycle engine. In order to avoid  
damage to the unit, do not mix oil with  
Gasoline.  
1. Remove fuel cap (Fig. 7).  
Definition of Blended Fuels  
Today's fuels are often a blend of gasoline and  
oxygenates such as ethanol, methanol or MTBE (ether).  
Alcohol-blended fuel absorbs water. As little as 1%  
water in the fuel can make fuel and oil separate or form  
acids when stored. Use fresh fuel (less than 60 days  
old), when using alcohol-blended fuel.  
WARNING: Remove fuel cap slowly to avoid  
injury from gasoline spray.  
Using Blended Fuels  
If you choose to use a blended fuel, or its use is  
unavoidable, follow recommended precautions.  
Always use fresh unleaded gasoline  
®
Use the fuel additive STA-BIL or an equivalent.  
Drain tank and run the engine dry before storing unit.  
Using Fuel Additives  
®
The use of fuel additives, such as STA-BIL Gas  
Stabilizer or an equivalent, will inhibit corrosion and  
minimize the formation of gum deposits. Using a fuel  
additive can keep fuel from forming harmful deposits in  
the carburetor for up to six (6) months. Add 0.8 oz.  
(23 ml.) of fuel additive per gallon of fuel according to the  
instructions on the container. NEVER add fuel additives  
directly to the unit's gas tank.

of trimming line is released. A blade in the cutting  
attachment shield will cut the line to the proper length if  
excess line is released.  
WARNING: Always wear eye, hearing, foot  
and body protection to reduce the risk of  
injury when operating this unit.  
For best results, tap the Bump Headon bare ground  
or hard soil. If line release is attempted in tall grass, the  
engine may stall. Always keep the trimming line fully  
extended. Line release becomes more difficult as the  
cutting line becomes shorter.  
Before operating the unit, stand in the operating position  
(Fig. 14). Check for the following:  
The operator is wearing eye protection and proper  
clothing.  
NOTE: Do not rest the Bump Headon the ground  
The right arm is slightly bent, and the hand is holding  
the shaft grip.  
while the unit is running .  
CAUTION: Do not remove or alter the line  
cutting blade assembly. Excessive line length  
will make the clutch overheat. This may lead  
to serious personal injury or damage to the  
unit.  
The left arm is straight, and the hand is holding the  
J-handle.  
Some line breakage will occur from:  
Entanglement with foreign matter  
Normal line fatigue  
Attempting to cut thick, stalky weeds  
Forcing the line into objects such as walls or fence  
posts  
TIPS FOR BEST TRIMMING RESULTS  
Keep the cutting attachment parallel to the ground.  
Do not force the cutting attachment. Allow the tip of  
the line to do the cutting, especially along walls.  
Cutting with more than the tip will reduce cutting  
efficiency and may overload the engine.  
Fig. 14  
The unit is at waist level.  
Cut grass over 8 inches (200 mm) by working from  
top to bottom in small increments to avoid  
premature line wear or engine drag.  
The sweeper/blower is parallel to the ground and is  
positioned so debris is blown away from operator.  
ADJUSTING TRIMMING LINE LENGTH  
Cut from left to right whenever possible. Cutting to  
the right improves the unit's cutting efficiency.  
Clippings are thrown away from the operator.  
The Bump Headcutting attachment allows you to  
release trimming line without stopping the engine. To  
release more line, lightly tap the cutting attachment on  
the ground (Fig. 15) while operating the trimmer at high  
speed.  
Slowly move the trimmer into and out of the cutting  
area at the desired height. Move either in a forward-  
backward or side-to-side motion. Cutting shorter  
lengths produces the best results.  
NOTE: Always keep the trimming line fully extended.  
Line release becomes more difficult as cutting  
line becomes shorter  
Trim only when grass and weeds are dry.  
The life of your cutting line is dependent upon;  
Following the previous trimming techniques  
What vegetation is being cut  
Where its being cut  
For example, the line will wear faster when trimming  
against a foundation wall as opposed to trimming  
around a tree.

MAINTENANCE AND REPAIR INSTRUCTIONS  
CHECKING THE OIL LEVEL  
CHANGING THE OIL  
For a new engine, change the oil after the first 10 hours  
of operation. Change the oil while the engine is still  
warm. The oil will flow freely and carry away more  
impurities.  
CAUTION: To prevent extensive engine wear  
and damage to the unit, always maintain the  
proper oil level in the crankcase. Never  
operate the unit with the oil level below the  
bottom of the dipstick.  
CAUTION: Wear gloves to prevent injury  
when handling the unit.  
The importance of checking and maintaining the proper  
oil level in the crankcase cannot be overemphasized.  
Check oil before each use:  
1. Unplug spark plug boot to eliminate starting  
2. Remove the oil fill plug/dipstick.  
1. Stop engine and allow oil to drain into the crankcase.  
2. Place the unit on a flat, level surface to get a proper  
oil level reading.  
3. Pour the oil out of the oil fill hole and into a container  
by tipping the unit to a vertical position (Fig. 30).  
Allow ample time for complete drainage.  
3. Keep dirt, grass clippings, etc., out of the engine.  
Clean the area around the oil fill plug/dipstick before  
removing it.  
4. Remove the oil fill plug/dipstick and wipe off oil.  
Reinsert it all the way back in.  
5. Remove the oil fill plug/dipstick and check oil level.  
Oil should be up to the top of the dipstick (Fig. 28).

5. Refill the crankcase with 3.4 fluid ounce (100 ml) of  
SAE 30 SF, SG, SH oil.  
NOTE: Use the bottle and spout saved from initial use to  
measure the correct amount. 3.4 ounce (100 ml)  
is approximately to the top of the label on the  
bottle (Fig. 31). Check the level with the dipstick.  
If the level is low, add a small amount of oil and  
recheck (Fig. 28). Do not overfill.  
6. If the level is low, add a small amount of oil to the oil  
fill hole and recheck (Fig. 29). Repeat until the oil  
level reaches the top of the dipstick.

MAINTENANCE AND REPAIR INSTRUCTIONS  
CARBURETOR ADJUSTMENT  
The idle speed of the engine is adjustable. An idle  
adjustment screw is reached though a hole in the top of  
the engine cover (Fig 37).  
Idle Adjustment Screw  
NOTE: Careless adjustments can seriously damage your  
unit. An authorized service dealer should make  
carburetor adjustments.  
Check Fuel  
Old fuel is usually the main reason for the unit not  
running properly. Drain and refill the tank with clean,  
fresh unleaded fuel prior to doing any adjustments. Refer  
to Oil and Fuel Information.  
Clean Air Filter  
The condition of the air filter is important to the  
operation of the unit. A dirty air filter will restrict air flow  
and change the air/fuel mixture. This is often mistaken  
for an out of adjustment carburetor. Check the condition  
of the air filter before adjusting the idle speed screw.  
Refer to Air Filter Maintenance.  
Fig. 37  
3. If the cutting attachment rotates when the engine  
idles, turn the idle speed screw counterclockwise 1/8  
of a turn at a time (as needed), to reduce idle speed.  
Checking the fuel, cleaning the air filter, and adjusting  
the idle speed screw should solve most engine  
problems.  
Adjust Idle Speed Screw  
WARNING: The cutting attachment may be  
spinning during idle speed adjustment. Wear  
protective clothing and observe all safety  
instructions to prevent serious personal  
injury.  
If not and:  
The engine will not idle,  
The engine hesitates or stalls on acceleration,  
There is a loss of engine power,  
If after checking the fuel and cleaning the air  
filter the engine still will not idle, adjust the idle speed  
screw as follows.  
have the carburetor adjusted by an authorized service  
dealer.  
1. Start the engine and let it run at a high idle for a  
minute to warm up.  
WARNING: When the unit is turned off make  
sure the cutting attachment has stopped  
before the unit is set down to prevent serious  
personal injury.  
2. Release the throttle trigger and let the engine idle. If  
the engine stops, insert a small phillips or flat blade  
screwdriver into the hole in the engine cover  
(Fig. 37). Turn the idle speed screw in, clockwise,  
1/8 of a turn at a time (as needed) until the engine  
idles smoothly.  
NOTE: The cutting attachment should not rotate when  
the engine idles.

CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT  
YOUR WARRANTY RIGHTS AND OBLIGATIONS  
The California Air Resources Board and Ryobi  
MANUFACTURER'S WARRANTY COVERAGE:  
Outdoor Products (ROP), are pleased to explain the  
emission control system warranty on your 2000 and  
later small off-road engine. In California, new small  
off-road 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 small off-road engine for the periods  
of time listed below provided there has been no  
abuse, neglect or improper maintenance of your small  
off-road 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 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.  
Where a warrantable condition exists, ROP will repair  
your small off-road engine at no cost to you including  
diagnosis, parts and labor.  
The 2000 and later small off-road 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 small off-road engine owner, you are  
responsible for the performance of the required  
maintenance listed in your operator's manual. ROP  
recommends that you retain all receipts covering  
maintenance on your small off-road engine, but  
ROP cannot deny warranty solely for the lack of  
receipts or for your failure to ensure the  
The manufacturer is liable for damages to other  
engine components caused by the failure of a  
warranted part still under warranty.  
Failures caused by abuse, neglect or improper  
maintenance are not covered under warranty.  
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.  
performance of all scheduled maintenance.  
As the small off-road engine owner, you should  
however be aware that ROP may deny you warranty  
coverage if your small off-road engine or a part has  
failed due to abuse, neglect, improper maintenance  
or unapproved modifications.  
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.  
You are responsible for presenting your small  
off-road 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.  
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.  
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.
