Before Operation 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.

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 1/41/2 inch (6mm13mm) from the top of the tank.

6. Tighten the tank fuel cap carefully but firmly after refilling.

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. NO TAG).

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 Manufacturers Association (NMMA) or BIA certified oils. This type of 2cycle engine oil does not have the proper additives for air-cooled, 2cycle 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, 2cycle 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.

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 TOROS

10

STABILIZER/CONDITIONER OR A SIMILAR PRODUCT. TOROS STABILIZER/CONDITIONER IS A PETROLEUM DISTILLATE BASED CONDITIONER/STABILIZER.

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 Gasoline And Oil IMPORTANT: The engine used on this String Trimmer is of a 2cycle 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 2cycle air cooled engines. Toro 50:1 2Cycle 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.

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.

Fuel Mixture Chart

Gasoline 50:1 2-cycle oil

1 gallon 2.6 oz.

2 gallons 5.2 oz.

5 gallons 12.8 oz.

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.

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 1/41/2 inch (6mm13mm) from the top of the tank. Avoid filling to the top of the tank filler neck.

11

Starting And Stopping

Before Starting The Engine

Idle Speed Adjustment This Brushcutter is equipped with non-adjustable fuel mixture carburetor. The engine idle speed is the only adjustment for the operator.

POTENTIAL HAZARD Engine must be running to make some

carburetor adjustments. When engine is running, Brushcutter blade is

rotating and other parts are moving.

WHAT CAN HAPPEN Contact with rotating Brushcutter blade or

other moving parts could cause serious personal injury or death.

HOW TO AVOID THE HAZARD Keep hands, feet and clothing away from

Brushcutter blade and other moving parts. Keep all bystanders and pets away from unit

while making carburetor adjustments.

The Brushcutter blade 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 Brushcutter blade must not rotate and the engine should not stall (stop running) at engine idle speed.

To adjust the engine idle speed, rotate the idle speed adjustment screw on the carburetor (Fig. 20).

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!

Contact your local authorized Toro Dealer for assistance and servicing.

Figure 20 1. Idle Speed Adjustment Screw

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 air cleaner cover (Fig. 17).

2. Loosen the knob and lift off the cylinder cover (Fig. 17).

3. Clean all dirt and debris from the cooling fins and from around the cylinder base.

4. Reinstall the cylinder and air cleaner covers (Figs 17).

Spark Arrester

POTENTIAL HAZARD Muffler surface becomes hot when Brushcutter

is in operation and remains hot for some time after the engine is shut off.

WHAT CAN HAPPEN Contact with hot muffler surfaces could cause a

burn.

HOW TO AVOID THE HAZARD Make sure the muffler is cool before inspecting

and cleaning the spark arrester.

Maintenance Interval

The spark arrester should be inspected and cleaned after every 25 hours of use.

Replace the screen if it cannot be thoroughly cleaned, or if it is damaged.

Spark Arrester Maintenance

1. With the engine at ambient (room) temperature, loosen the knob and remove the air cleaner cover (Fig. 17).

2. Loosen the knob and lift off the cylinder cover (Fig. 17).

3. Remove the two socket head screws holding the spark arrester assembly to the muffler (Fig. 21).

General Cleaning and Tightening

POTENTIAL HAZARD When engine is running, cutting blade is

rotating and other parts are moving.

WHAT CAN HAPPEN Contact with rotating cutting blade or other

moving parts could cause serious personal injury or death.

HOW TO AVOID THE HAZARD Always turn off your Brushcutter before you

clean or perform any maintenance on it.

The Toro Brushcutter will provide maximum performance for many, many hours if it is maintained properly. Good maintenance includes regular checking of all fasteners for correct tightness, and cleaning the entire machine.

Blade Sharpening IMPORTANT: Replace any blade that is worn, cracked or damaged.

IMPORTANT: Sharpen every tooth evenly so the blade rotates smoothly. If you sharpen a blade with a grinder, do not overheat the blade, and do not quench a hot blade in water to cool it.

Federal and California Emission Control Warranty Statement A Two Year Limited Warranty

Your Warranty Rights and Obligations

The U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB) and Toro are pleased to explain the emission control system warranty on your 1995 and later utility/lawn/garden equipment engine. In California, new utility/lawn/garden equipment engines must be designed, built and equipped to meet the States stringent antismog standards. In other states, new 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.

Manufacturers Warranty Coverage:

Utility/Lawn/Garden equipment engines are warranted for two years from the date of delivery. If any emissionrelated part on your engine is defective in materials or workmanship, the part will be repaired or replaced by Toro free of charge.

Owners Warranty Responsibilities:

As the engine owner, you are responsible for the performance of the required maintenance listed in your owners 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 nonwarranty 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:

Toro Customer Service Department 8111 Lyndale Avenue South Bloomington, MN 554201196 6128888801 8003482424

Warranted Parts:

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 addon 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 addon or modified parts. Toro 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.

Any warranted part which is not scheduled for replacement as required maintenance, or which is scheduled only for regular inspection to the effect of repair or replace as necessary shall be warranted for the warranty period. Any warranted part which is scheduled for replacement as required maintenance shall be warranted for the period of time up to the first scheduled replacement point for that part. Coverage under this warranty extends only to the parts listed below (the emissions system parts) to the extent that these parts were present on the engine when purchased.
