maintained in effective working order,

or the engine be constructed, equipped

and maintained for the prevention of

fire. Check with your state or local

authorities for regulations pertaining to

these requirements. Failure to follow

these requirements could subject you

to liability or a fine. This unit is not

factory equipped with a spark

arrestor. If these items are required in

your area, ask your dealer to install the

Optional Accessory Part #180030

Spark Arrestor Kit.

Fueling And Before Operating

1. Gasoline is extremely flammable and its vapors

can explode if ignited. Always stop the engine

and allow it to cool before filling the fuel tank.

Do not smoke while filling the fuel tank. Keep

sparks and open flames away from the area.

EN–7

Before Starting

Oil & Fuel

THIS ENGINE IS CERTIFIED TO OPERATE

ON UNLEADED GAS AND OIL MIXTURE.

Note: BE SURE TO READ THESE

INSTRUCTIONS CAREFULLY

BEFORE ATTEMPTING TO START

OR OPERATE THIS UNIT. Using old

or improper oil or fuel, or improperly

mixing the oil and fuel can cause

engine damage. This type of damage

will void the engine warranty.

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.

Recommended Oil Type

An 8 oz. (0.24 liter) bottle of 2-cycle engine oil is

included with your product.

TORO 2-cycle oil is recommended for this outdoor

power tool. If another brand of 2-cycle oil is used,

make sure it is high quality oil, formulated for

2-cycle, air-cooled engines.

POTENTIAL HAZARD

• Gasoline/oil mixture contains petroleum

distillate.

WHAT CAN HAPPEN

• Gasoline/oil mixture can be harmful or

fatal if swallowed. It can also irritate your

skin.

HOW TO AVOID THE HAZARD

• Do not drink gasoline/oil mixture.

• Avoid prolonged contact with skin. Wash

thoroughly after handling.

• Do not reuse oil bottle.

IMPORTANT: If gasoline/oil mixture is

swallowed, do not induce vomiting. CALL

PHYSICIAN IMMEDIATELY.

Recommended Fuel Type

Use clean, fresh, unleaded gasoline that is less than

60 days old.

Note: Alcohol blended fuel absorbs moisture

(water). As little as 1% moisture in the

fuel can cause fuel and oil to separate

and form acids when stored.

If this type of fuel must be used, use

fresh fuel, (less than 60 days old) and

mix according to the mixing

instructions.

Definition Of Blended Fuels

Today’s fuels are often a blend of gasoline and one or

more oxygenates such as ethanol, methanol or MTBE

(ether).

Use Of Blended Fuels

If you choose to use a blended fuel or its use is

unavoidable, the following precautions are

recommended.

EN–8

1. Always use fresh fuel mix per your operator’s

manual.

2. Use a special additive such as Toro Gas

Stabilizer/Conditioner, STA-BILr or an

equivalent.

3. Always agitate the fuel mix before fueling the

unit.

4. Drain the tank and run the engine dry before

storing the unit.

Use Of Fuel Additives

The use of fuel additive, such as Toro Gas

Stabilizer/Conditioner, STA-BILr Gas Stabilizer or

an equivalent, will inhibit corrosion and minimize the

formation of gum deposit. Add 0.8 oz (23 ml) per

gallon of fuel per instructions on container. NEVER

add fuel additives directly to the unit’s fuel tank.

Using a fuel additive can keep fuel fresh for up to

six (6) months.

Mixing Oil And Fuel

Note: For proper engine operation and

maximum reliability, pay strict

attention to the oil and fuel mixing

instructions on the 2-cycle oil

container. Use a 32:1 fuel/oil ratio

when you use 2-cycle oil. Using

improperly mixed fuel can severely

damage the engine.

Thoroughly mix the proper ratio of 2-cycle engine oil

with unleaded gasoline in a separate fuel can, 32:1.

Do not mix them directly in the engine fuel tank. See

the table below for specific gas and oil mixing

ratios.

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 being

sprayed with fuel.

Operation

Starting/Stopping

1. Mix oil with gas and fill fuel tank with fuel/oil

mixture — per instructions on page 8.

2. Put the ignition switch in the “on” position. See

Fig. 10 for the location of the ON/OFF

SWITCH.

3. Fully press and release the primer bulb 5 to 7

times. See Fig. 11 for the primer bulb location.

4. Place the choke lever in the full “choke”

position. See Fig. 11.

5. With the unit on the ground, squeeze the throttle

trigger fully and pull the starter rope briskly

(Fig. 12) until the engine sounds like it wants to

run. (Normally 2 to 5 pulls).

6. Place the choke lever in the “partial” choke

position (fig. 11). pull the starter rope briskly 1

to 3 times to start the engine (Fig. 12).

7. If the engine does not start, repeat steps 4

through 6.

8. After the engine warms up for 5 to 10 seconds,

place the choke lever in the “run” position

(Fig. 11).

9. To stop the engine, put the ignition switch in the

“off” position (Fig. 10).

EN–9

Note: When storing the unit or when setting

unit down between uses, place the unit

flat on the floor so it sits on its stand

instead of hanging it by the guard or

the cutting head (Fig. 13).

Using The Brush Blade

Note: Always use the shoulder harness when

using the brush blade accessory.

1. Always maintain the proper stance for using the

brush blade kit (Fig. 14).

Sharpening The Brush Blade

IMPORTANT: Do not sharpen the brush

blade.

POTENTIAL HAZARD

• Sharpening the blade can cause the blade

tip to break off while in use.

WHAT CAN HAPPEN

• Contact with a thrown blade or piece of

blade could result in serious personal

injury to operator or bystanders.

HOW TO AVOID THE HAZARD

• DO NOT SHARPEN THE BRUSH

BLADE. Replace blade if dull.

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 Toro Service Dealer.

Adjusting The Trimming Line

Length

Your trimmer is equipped with a bump head that

allows the operator to release more trimming line

without stopping the engine. To release additional

line, lightly tap the trimming head on the ground

(Fig. 15) while operating the trimmer at high speed.

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 1 in (25.4 mm)

of trimming line is released. A blade in the string

guard will cut the line to the proper length if excess
