WHILE OPERATING WITH

CUTTING BLADE

• Read and understand all safety warnings before

operating this unit.

• Always use the shoulder harness when using the

brush blade accessory.

• Keep the J-handle between the operator and cutting

attachment or blade at all times.

• NEVER cut when the cutting blade is 30 inches

(76 cm) or more above the ground level.

• Blade thrust may occur when the spinning blade

contacts an object that it does not immediately cut.

Blade thrust can be violent enough to propel the unit

and/or operator in any direction, possibly causing a loss

of control. Blade thrust can occur without warning if the

blade snags, stalls or binds. This is more likely to occur

in areas where it is difficult to see the material being cut.

• For operation with the brush blade, do not cut

anything thicker than 1/2 inch or a violent kickback

could occur.

5

RULES FOR SAFE OPERATION

• Do not attempt to touch or stop the blade when it is

rotating.

•A coasting blade can cause injury while it continues to

spin after the engine is stopped or the throttle trigger

is released. Maintain proper control until the blade has

completely stopped rotating.

• Do not run the unit at high speed when not cutting.

• If you strike or become entangled with a foreign

object, stop the engine immediately and check for

damage. Have any damage repaired before attempting

further operations. Do not operate unit with a bent,

cracked or dull blade. Discard blades that are bent,

warped, cracked or broken.

• Do not sharpen the cutting blade. Sharpening the blade

can cause the blade tip to break off while in use. This

can result in severe personal injury. Replace the blade.

• Do not use the cutting blade for edging or as an edger;

severe personal injury to yourself or others may incur.

Use the cutting blade only for the purpose described

in this manual.

• Stop the engine IMMEDIATELY if you feel excessive

vibration. Vibration is a sign of trouble. Inspect

thoroughly for loose nuts, bolts or damage before

continuing. Repair or replace affected parts as

necessary.

After Use

• Clean cutting blades with a household cleaner to

remove any gum buildup. Oil the blade with machine

oil to prevent rust.

• Lock up and store the cutting blade in an appropriate

area to protect the blade from unauthorized use or

damage.

OIL AND FUEL INFORMATION

RECOMMENDED OIL TYPE

Using the proper type and weight of oil in

the crankcase is extremely important.

Check the oil before each use and change

the oil regularly. Failure to use the correct oil, or using

dirty oil, can cause premature engine wear and failure.

Use a high-quality SAE 30 weight oil of API (American

Petroleum Institute) service class SF, SG, SH.

ADDING OIL TO CRANKCASE: INITIAL USE

NOTE: This unit is shipped without oil. In order to avoid

damage to the unit, put oil in the crankcase

before you attempt to start the unit.

Your unit is supplied with one 3.4 fluid oz. (100 ml.)

bottle of SAE 30 SF, SG, SH oil (Fig. 16).

NOTE: Save the bottle of oil. It can be used to measure

the correct amount during future oil changes.

See Changing the Oil.

OIL AND FUEL INFORMATION

FUELING THE UNIT

1. Remove the fuel cap (Fig. 19).

Fig. 19

Fuel Cap

Fuel Tank

Gas Can Spout

2. Place the gas container’s spout into the fill hole on

the fuel tank (Fig. 19) and fill the tank.

NOTE: Do not overfill the tank.

3. Wipe up any gasoline that may have spilled.

4. Reinstall the fuel cap.

5. Move the unit at least 30 ft. (9.1 m) from the fueling

source and site before starting the engine.

NOTE: Dispose of the old gasoline in accordance to

Federal, State and Local regulations.

RECOMMENDED FUEL TYPE

Old fuel is the primary reason for improper unit

performance. 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.

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.

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.

Unleaded

Gasoline

Add fuel in a clean,

well ventilated

outdoor area. Wipe up any spilled fuel

immediately. Avoid creating a source of

ignition for spilt fuel. Do not start the engine

until fuel vapors dissipate.

WARNING:

Gasoline is

extremely

flammable. Ignited Vapors may explode.

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 at a distance from the area.

WARNING:

Remove fuel cap

slowly to avoid injury

from fuel spray. Never operate the unit

without the fuel cap securely in place

.

OPERATING INSTRUCTIONS

HOLDING THE TRIMMER

Before operating the unit, stand in the operating position

(Fig. 27). Check for the following:

• The operator is wearing eye protection and proper

clothing

• With a slightly-bent right arm, the operator’s right hand

is holding the shaft grip

• The operator’s left arm is straight, the left hand holding

the handle

• The unit is at waist level

• The cutting attachment is parallel to the ground and

easily contacts the grass without the need to bend over

After starting the unit and standing in the operating position,

hook the shoulder strap to the unit (CC4090 only).

Fig. 27

ADJUSTING TRIMMING LINE LENGTH

The Bump Head™ cutting attachment allows you to

release trimming line without stopping the engine. To

release more line, lightly tap the cutting attachment on the

ground (Fig. 28) while operating the trimmer at high speed.

NOTE: Always keep the trimming line fully extended.

Line release becomes more difficult as the cutting

line becomes shorter.

Each time the head is bumped, about 1 inch (25.4 mm) 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.

For best results, tap the Bump Head™ on 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.

NOTE: Do not rest the Bump Head™ on the ground

while the unit is running.

Fig. 28

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

• For best trimming results, operate unit at full throttle.

• 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.

• Cut grass over 8 inches (200 mm) by working from top

to bottom in small increments to avoid premature line

wear or engine drag.

• For the CC4090 brushcutter, cut from left to right

whenever possible. Cutting to the right improves the

unit's cutting efficiency. Clippings are thrown away from

the operator. For the other units, cut from right to left.

• 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.

• Trim only when grass and weeds are dry.

• The life of your cutting line is dependent upon:

• Proper adherence of explained trimming techniques

• What vegetation is cut

• Where vegetation is cut

For example, the line will wear faster when trimming against

a foundation wall as opposed to trimming around a tree.

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.

CAUTION:

Always wear eye,

hearing, foot and

body protection to reduce the risk of injury

when operating this unit.

WARNING:

Fig. 31

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing all

vegetation around trees, posts, fences and more.

Rotate the whole unit so that the cutting attachment is at

a 30° angle to the ground (Fig. 29).

CC4090 ONLY: USING THE CUTTING BLADE

Before operating the unit with the cutting blade, stand in

the operating position (Fig. 30). Refer to Holding the

Trimmer.

Cutting Blade Operating Tips

To establish a rhythmic cutting procedure:

• Plant feet firmly, comfortably apart.

• Bring the engine to full throttle before entering the

material to be cut. At full throttle the blade has

maximum cutting power and is less likely to bind, stall

or cause blade thrust (which can result in serious

personal injury to the operator or others).

• Cut while swinging the upper part of your body from

left to right.

• Always release the throttle trigger and allow the engine

to return to idle speed when not cutting.

• When you are finished, always unsnap the unit from

the harness before taking off the harness.

• Swing the unit in the opposite direction as the blade

spins, which increases the cutting action.

• After the return swing, move forward to the next area

to be cut plant your feet again.

• The cutting blade is designed with a second cutting

edge. You can use it by removing the blade, turning it

upside down, and reinstalling it.

To reduce the chance of material wrapping around the

blade, follow these steps:

• Cut at full throttle

• Swing the unit into material to be cut from your left to

your right (Fig. 31)

• Avoid the material just cut as you make the return swing

Always wear eye,

hearing, foot, body

protection and the shoulder strap to reduce the

risk of injury when operating this unit.

WARNING:

Do not use the

cutting blade for

edging or as an edger. Severe personal injury

to yourself or others can result.

WARNING:

The blade continues

to spin after the

engine is turned off. The coasting blade can

seriously cut you if accidentally touched.

WARNING:

Do not sharpen the

cutting blade.

Sharpening the blade can cause the blade tip

to break off while in use. This can result in

severe personal injury to yourself or others.

Replace the blade.

WARNING:

Bl

ade thrust may

occur when the

spinning blade contacts an object that it does

not immediately cut. Blade thrust can be violent

enough to cause the unit and/or operator to be

propelled in any direction, and possibly lose

control of the unit. Blade thrust can occur

without warning if the blade snags, stalls or

binds. This is more likely to occur in areas where

it is difficult to see the material being cut.

WARNING:

Do not clear away

any cut material with

the engine running or blade turning. To avoid

serious personal injury, turn off the engine.

Allow the blade to stop before removing

materials wrapped around the blade shaft.
