Oil and Fuel
POTENTIAL HAZARD
• In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
• A fire or explosion from gasoline can burn you,
others, and cause property damage.
HOW TO AVOID THE HAZARD
• Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is cold. Wipe up any gasoline that spills.
• Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4” to 1/2” (6 mm to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where gasoline fumes may be ignited by a spark.
• Store gasoline in an approved container and
keep it out of the reach of children.
• Never buy more than a 30-day supply of
gasoline.
1. Do not smoke near fuel.
2. Mix and pour fuel outdoors and where there are no
sparks or flames.
7. Wipe up any spilled fuel before starting the engine.
8. Move the String Trimmer at least 10 feet (3 m) away
from the fueling location and fuel storage container before starting the engine (Fig. 2).
Recommended Oil Type
Only use a two-cycle engine oil formulated for use in high-performance, air-cooled two-cycle engines. Toro brand 2-cycle oil is formulated for use in high-performance, air-cooled two-cycle engines.
IMPORTANT: Do not use National Marine Manufacturer’s Association (NMMA) or BIA certified oils. This type of 2–cycle engine oil does not have the proper additives for air-cooled, 2–cycle engines and can cause engine damage.
Do not use automotive motor oil. This type of oil does not have the proper additives for air-cooled, 2–cycle engines and can cause engine damage.
Recommended Fuel Type
Use clean, fresh lead-free gasoline, including oxygenated or reformulated gasoline, with an octane rating of 85 or higher. To ensure freshness, purchase only the quantity of gasoline that can be used in 30 days. Use of lead-free gasoline results in fewer combustion chamber deposits and longer spark plug life. Use of premium grade fuel is not necessary or recommended.
3. Always shut off the engine before refueling. Never
remove the String Trimmer fuel tank cap while the engine is running or right after just stopping the engine.
POTENTIAL HAZARD
• Gasoline contains gasses that can build up
pressure inside a gas tank.
WHAT CAN HAPPEN
• Fuel can be sprayed on you when removing gas
cap.
HOW TO AVOID THE HAZARD
• Remove fuel cap slowly to avoid injury from
fuel spray.
4. Always open the fuel tank cap slowly to release any
possible overpressure inside the tank.
5. Do not overfill the fuel tank. Stop filling 1/4–1/2 inch
(6mm–13mm) from the top of the tank.
Use Of Fuel Additives
IMPORTANT: NEVER USE METHANOL, GASOLINE CONTAINING METHANOL GASOHOL CONTAINING MORE THAN 10% ETHANOL, PREMIUM GASOLINE, OR WHITE GAS BECAUSE ENGINE FUEL SYSTEM DAMAGE COULD RESULT.
DO NOT USE FUEL ADDITIVES OTHER THAN THOSE MANUFACTURED FOR FUEL STABILIZATION DURING STORAGE SUCH AS TORO’S STABILIZER/CONDITIONER OR A SIMILAR PRODUCT. TORO’S STABILIZER/CONDITIONER IS A PETROLEUM DISTILLA TE BASED CONDITIONER/STABILIZER.
,
11
Page 12
TORO DOES NOT RECOMMEND STABILIZERS WITH AN ALCOHOL BASE SUCH AS ETHANOL, METHANOL OR ISOPROPYL. ADDITIVES SHOULD NOT BE USED TO TRY TO ENHANCE THE POWER OR PERFORMANCE OF MACHINE.
Mixing Instructions
IMPORTANT: Never mix gasoline and oil directly in the String Trimmer fuel tank.
1. Always mix fuel and oil in a clean container approved
for gasoline.
2. Mark the container to identify it as fuel mix for the
String Trimmer.
Mixing Gasoline And Oil
IMPORTANT: The engine used on this String Trimmer is of a 2–cycle design. The internal moving parts of the engine, i.e., crankshaft bearings, piston pin bearings and piston to cylinder wall contact surfaces, require oil mixed with the gasoline for lubrication.
Failure to add oil to the gasoline or failure to mix oil with the gasoline at the appropriate ratio will cause major engine damage which will void your warranty.
For your fuel premix, only use a quality oil designed for 2–cycle air cooled engines. Toro 50:1 2–Cycle Oil is formulated to meet the requirements of high-performance, air-cooled two-cycle engines.
Fuel Mixture
The fuel:oil ratio is 50 parts gasoline to 1 part oil or 50:1.
3. Use regular unleaded gasoline and fill the container
with half the required amount of gasoline.
4. Pour the correct amount of oil into the container then
add the remaining amount of gasoline.
5. Close the container tightly and shake it momentarily to
evenly mix the oil and the gasoline before filling the fuel tank on the String Trimmer.
6. When refilling the String Trimmer fuel tank, clean
around the fuel tank cap to prevent dirt and debris from entering the tank during cap removal.
7. Always shake the premix fuel container momentarily
before filling the fuel tank
8. Always use a spout or funnel when fueling to reduce
fuel spillage.
9. Fill the tank only to within 1/4–1/2 inch (6mm–13mm)
from the top of the tank. Avoid filling to the top of the tank filler neck.
Note: Never use a mixing ratio less than 50:1 regardless of the oil package mixing instructions. Ratios less the 50:1, (for example, 60:1, 80:1, 100:1), reduce the amount of lubrication to the internal moving parts of the engine and can cause damage.

m-2931
Page 20
POTENTIAL HAZARD
• Engine must be running to make some
carburetor adjustments.
• When engine is running, trimmer head is
rotating and other parts are moving.
WHAT CAN HAPPEN
• Contact with rotating trimmer head or other
moving parts could cause serious personal injury or death.
HOW TO AVOID THE HAZARD
• Keep hands, feet and clothing away from
trimmer head and other moving parts.
• Keep all bystanders and pets away from unit
while making carburetor adjustments.
The trimmer head may be rotating during idle speed adjustment. Wear the recommended personal protective equipment and observe all safety instructions. Keep hands and body away from the trimmer head.
When the throttle trigger is released, the engine should return to an idle speed between 2400 and 2800 RPM, or just below the clutch engagement speed. The trimmer head must not rotate and the engine should not stall (stop running) at engine idle speed (Fig. 13).
Cylinder Cooling Fins
Maintenance Interval
The cylinder cooling fins should be cleaned after every 25 hours of operation, or once a week, whichever comes first.
Air must flow freely around and through the cylinder cooling fins to prevent engine overheating. Leaves, grass, dirt and debris buildup on the fins will increase the operating temperature of the engine, which can reduce engine performance and shorten engine life.
Cooling Fin Cleaning
1. With the engine cool (ambient or room temperature),
remove the socket head screw holding the muffler cover, then remove the muffler cover (Fig. 26).
2. Loosen the cylinder cover screw and remove the
cylinder cover (Fig. 22).
3. Clean all dirt and debris from the cooling fins and
from around the cylinder base.
4. Reinstall the cylinder cover and the muffler cover
(Figs 22 and 26).
T o adjust the engine idle speed, rotate the idle speed adjustment screw on the carburetor (Fig. 25).
• Turn the idle speed screw in (clockwise) to increase
the engine idle speed.
• Turn the screw out (counterclockwise) to decrease the
engine idle speed.
If idle speed adjustment is necessary, and after adjustment the trimmer head rotates or the engine stalls, stop using the String Trimmer immediately!

Federal Emission Control Warranty Statement
A Two Year Limited Warranty
Your Warranty Rights and Obligations
The U.S. Environmental Protection Agency (EPA) and Toro are pleased to explain the emission control system warranty on your 1997 and later utility/lawn/garden equipment engine. 1997 and later model year utility/lawn/garden equipment engines must be designed, built and equipped, at the time of sale, to meet the U.S. EPA regulations for small nonroad engines. The equipment 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. Toro must warrant the emission control system on your utility/lawn/garden equipment engine for the period of time listed above provided there has been no abuse, neglect or improper maintenance of your utility/lawn/garden equipment engine.
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, and connectors and other emission related assemblies.
Where a warrantable condition exists, Toro will repair your engine at no cost to you including diagnosis, parts and labor.
Manufacturer’s Warranty Coverage:
The 1997 and later utility/lawn/garden equipment engines are warranted for two years from the date of delivery . If any emission–related part on your engine is defective in materials or workmanship, the part will be repaired or replaced by T oro free of charge.
Owner’s Warranty Responsibilities:
• As the engine owner, you are responsible for the performance of the required maintenance listed
in your owner’s manual. Toro recommends that you retain all receipts covering maintenance on your equipment, but Toro 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 the engine manufacturer.
• As the engine owner, you should, however, be aware that Toro may deny you warranty
coverage if your engine or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications or parts.
• You are responsible for presenting your equipment engine to a TORO 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 or if you need a
referral to a TORO Service Dealer, please feel free to contact us at the following address:

The warranty period begins on the date the engine or equipment is delivered to a retail purchaser. The manufacturer warrants to the initial owner and each subsequent purchaser that the engine 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.
Failures caused by abuse, neglect, or improper maintenance are not covered. The use of add–on or modified parts can be grounds for disallowing a warranty claim. The manufacturer is not liable to cover failures of warranted parts caused by the use of add–on or modified parts. T oro is liable for damages to other engine components caused by the failure of a warranted part still under warranty. The owner is responsible for the performance of the required maintenance, as defined by the manufacturer in the written instructions.
