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=05245 Muffler Assembly.
This Unit Can Use an Power Start or Power Start Bit Optional Accessory! Please refer to the Power Starter or Power Start Bit operator's manual for proper use of these features. (Items may be Sold Separately! Please refer to page 9 of this manual for more information about purchasing these accessories.)
Read the Operator's Manual and follow all warnings and safety instructions. Failurs to do so can result in serious injury to the operator and/or bystanders. FOR QUESTIONS, CALL 1-800-4-MY-HOME®

• iMPORTANT SAFETY iNSTRUCTiONS READ ALL iNSTRUCTiONS
BEFORE OPERATING
Always stop the engine and allow it to cool before filling the fuel tank. Never remove the cap of the fuel tank, or add fuel, when the engine is hot. Never operate the unit without the fuel cap securely in place. Loosen the fuel tank cap slowly to relieve any pressure in the tank.
• Read the instructions carefully. Be familiar with the controls and proper use of the unit. Do not operate this unit when tired, ill, or under the influence of alcohol, drugs, or medication.
Add fuel in a clean, well-ventilated outdoor area where there are no sparks or flames. Slowly remove the fuel cap only after stopping engine. Do not smoke while fueling. Wipe up any spilled fuel from the unit immediately. Always wipe unit dry before using. Move the unit at least 30 feet (9.1 m) from the fueling source and site before starting the engine. Do not smoke or allow sparks and open flames near the area while adding fuel or operating the unit. WHILE OPERATING
Children and teens under the age of 15 must not use the unit, except for teens guided by an adult. All guards and safety attachments must be installed properly before operating the unit. Inspect the unit before use. Replace damaged parts. Check for fuel leaks. Make sure all fasteners are in place and secure. Replace parts that are cracked, chipped, or damaged in any way. Do not operate the unit with loose or damaged parts.
Never start or run the unit inside a closed room or building. Breathing exhaust fumes can kill. Operate this unit only in a well ventilated outdoor area.
Carefully inspect the area before starting the unit. Remove all debris and hard or sharp objects such as glass, wire, etc. Clear the area of children, bystanders, and pets. At a minimum, keep all children, bystanders, and pets outside a 50 feet (15 m.) radius; there still may be a risk to bystanders from thrown objects. Bystanders should be encouraged to wear eye protection. If approached, stop the unit immediately.
Be aware of the risk of injury to the head, hands and feet. Wear safety glasses or goggles that are marked as meeting ANSI Z87.1-1989 standards. Also wear ear/hearing protection when operating this unit. Wear a face or dust mask if the operation is dusty. Long sleeve shirts are recommended. Wear heavy, long pants, boots and gloves. Do not wear loose clothing, jewelry, short pants, sandals or go barefoot. Secure hair above shoulder level.
Use only Craftsman Hassle-FreeTM XTRA QUIET Spiral Une or 0.095 inch (2.41 mm) diameter spool line as replacement line. Never use metal-reinforced line, wire or rope. These can break off and become dangerous projectiles. Squeeze the throttle control and check that it returns automatically to the idle position. Make all adjustments or repairs before using unit. SAFETY WARNINGS FOR GAS UNITS

The cutting attachment shield must always be in place while operating the unit. Do not operate unit without both trimming lines extended, and the proper line installed. Do not extend the trimming line beyond the length of the shield. This unit has a clutch. The cutting attachment remains stationary when the engine is idling. If it does not, have the unit adjusted by an authorized service technician. Adjust the D-handle position that will provide the best grip. Be sure the cutting attachment is not in contact with anything before starting the unit. Use the unit only in daylight or good artificial light. Avoid accidental starting. Be in the starting position whenever pulling the starter rope. The operator and unit must be in a stable position while starting. See Starting/Stopping Instructions.

manual
• Drain the tank and run the engine dry before storing the unit USING FUEL ADDITIVES The bottle of 2-cycle oil contains a fuel additive which will help inhibit corrosion and minimize the formation of gum deposits. It is recommended to use our 2-cycle oil with this unit. If unavailable, 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.
Fig. 5
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded fuel in a separate fuel can. Use a 40:1 fuel/oil ratio. Do not mix them directly in the engine fuel tank. See the table for specific gas and oil mixing ratios. NOTE: One gallon (3.8 liters) of unleaded fuel mixed with one 3.2 oz. (95 ml.) bottle of 2-cycle oil makes a 40:1 fuel/oil ratio. NOTE: Dispose of the old fuel/oil mix in accordance to Federal, State and Local regulations. may explode. Always stop the engine and allow it to cool before filling the fuel tank.

For best results, tap the cutting 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 cutting head on the ground while the unit is running. Some line breakage will occur from: • Entanglement

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.
