SPARK ARRESTOR NOTE NOTE: For users on U.S. Forest Land and in the states of California, Maine,

Oregon and Washington. All U.S. Forest Land and the state of California (Public Resources Codes 4442 and 4443), Oregon and Washington require, by

law that certain internal combustion engines operated on forest brush and/or grass-covered areas be equipped with a spark arrestor, 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 factory equipped with a spark

arrestor. If it requires replacement, ask your LOCAL SERVICE DEALER to install the Accessory Part #753=06182 Muffler Assembly

The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols, and their explanations, deserve your careful

Always hold the unit with both hands when operating. Keep a firm grip on both the front and rear handle or grips.

Keep hands, face, and feet at a distance from all moving parts. Do not touch or try to stop the cutting head when it is rotating.

Do not touch the engine or muffler. These parts get extremely hot from operation. They remain hot for ashort time after turning off the unit.

Do not operate the engine faster than the speed needed to cut, trim or edge. Do not run the engine at high speed when not cutting.

This unit has an overspeed protection switch to keep the unit from overheating. When the unit is run at full throttle while not in use for

extended lengths of time the overspeed protection switch will engage. Always stop the engine when cutting is delayed or when walking from one

cutting location to another. If the unit is struck or becomes entangled with a foreign object, stop the

engine immediately and check for damage. Do not operate before repairing damage. Do not operate the unit with loose or damaged parts.

Stop and switch the engine to off for maintenance, repair, or for changing the cutting head or other attachments.

Use only replacement parts and accessories listed in the Parts List section of this operator's manual and distributed by a Craftsman outlet or service

center. Use of any replacement parts or accessories purchased elsewhere may be hazardous and will also void the warranty.

Keep unit clean of vegetation and other materials. They may become lodged between the cutting head and shield.

To reduce fire hazard, keep the engine and muffler free from grass, leaves, excessive grease or carbon build up.

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 D-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.

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.

OTHER SAFETY WARNINGS

Never store the unit, with fuel in the tank, inside a building where fumes

may reach an open flame or spark. Allow the engine to cool before storing or transporting. Be sure to secure

the unit while transporting. Store the unit in a dry area, locked up or up high to prevent unauthorized

use or damage, out of the reach of children.

Never douse or squirt the unit with water or any other liquid. Keep handles

dry, clean and free from debris. Clean after each use. See the Cleaning and Storage instructions.

Keep these instructions. Refer to them often and use them to instruct other

users. If loaning someone this unit, also loan them these instructions.

OiL AND FUEL MiXiNG iNSTRUCTiONS Old and/or improperly mixed fuel are the main reasons for the unit not

running properly. Be sure to use fresh, clean unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.

Definition of Blended Fuels

_L_ WARNING" It has been proven that fuel containing greater than I

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. It forms acids when stored.

When using alcohol-blended fuel, use fresh fuel (less than 60 days old). Using Blended Fuels

If choosing to use a blended fuel, or its use is unavoidable, follow recommended precautions:

• Always use the fresh fuel mix explained in the operator's manual

• Always agitate the fuel mix before fueling the unit

• Drain the tank and run the engine dry before storing the unit

Using Fuel Additives

The bottle of 2-cycle oil that came with the unit contains a fuel additive that

will help inhibit corrosion and minimize the formation of gum deposits.

Always use a good 2-cycle oil designed for air-cooled engines along with a fuel additive, such as STA-BIL® Gas Stabilizer or an equivalent. 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 fuel tank.

Thoroughly mix the proper ratio of

2-cycle engine oil with unleaded gasoline in a separate fuel can. Use a 40:1 fuel/oil ratio. Do not mix

them directly in the engine fuel tank.

Do not force the cutting head. 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. Cut from right to left whenever possible. Cutting to the left improves the

unit's cutting efficiency. Clippings are thrown away from the operator.

Slowly move the unit 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 the cutting line is dependent upon:

Following the trimming techniques

What vegetation is being 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. 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

DECORATIVE TRiMMiNG

Decorative trimming is

accomplished by removing all vegetation around trees, posts,

fences, etc.

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). Fig. 19

WARNING: Blade 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 itisdifficult to see the material being cut.

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.

off. The coasting blade can seriously cut you if accidentally touched.

Swing the unit inthe opposite direction as the blade spins,

which increases the cutting action.

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

cut and 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.
