Installing Trimmer Head

IMPORTANT: Make sure the trimmer head is for LEFT-HAND ROTATION (counterclockwise) as viewed from the operator’s position, and that the trimmer head adapter is a male, M8 x 1.25 left-hand thread.

Before Operation

Oil and Fuel

1. Thread the trimmer head into the gearcase, tighten

trimmer head firmly by hand (Fig. 6).

Figure 6

1. Gearcase 2. Trimmer Head

POTENTIAL HAZARD

• If the trimmer head is not adequately tightened,

it can come loose from the Trimmer during use.

WHAT CAN HAPPEN

• This may cause damage to property or personal

injury.

HOW TO AVOID THE HAZARD

• Make sure the trimmer head is securely

fastened to the splined shaft in the gearcase.

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 1/4–1/2 inch

(6mm–13mm) 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. 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.

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.

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 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.

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.

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.

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.
