Make sure the switch is in the OFF position, the spark plug wire is disconnected, and the blade has stopped moving before removing jammed material from the cutting blade. Do not grab or hold the unit by the cutting blade.

Inspect unit before each use for worn,

loose, missing, or damaged parts. Do not use until unit is in proper working order. Keep outside surfaces free from oil and

fuel. Never start or run engine inside a closed

room or building. Breathing exhaust fumes can kill. Avoid dangerous environments. Do not use

MAINTAIN YOUR UNIT PROPERLY

Have all maintenance other than the rec-

ommended procedures described in the instruction manual performed by an authorized service dealer. Disconnect spark plug before performing

maintenance except for carburetor adjustments. Do not use a cutting blade that is bent,

warped, cracked, broken, or damaged in any other way. Have worn or damaged parts replaced by an authorized service dealer. Useonly recommended Jonsered!cutting

blades and replacement parts; use of any other parts may void your warranty and cause damage to your unit. Empty fuel tank before storing the unit. Use

and the muffler and cutting blade away from your body. Allow engine to cool, empty the fuel tank,

and secure the unit before storing or transporting it in a vehicle.

Safety Glasses

Do not store the unit orfuel in a closed area

where fuel vapors can reach sparks or an open flame from hot water heaters, electric motors or switches, furnaces, etc. Store the unit so the cutting blade cannot

accidentally cause injury. Store in a dry area out of reach of children.

SAFETY NOTICE:

through prolonged use of gasoline powered hand tools could cause blood vessel or nerve damage in the fingers, hands, and joints of people prone to circulation disorders or abnormal swelling. Prolonged use in cold weather has been linked toblood vessel damage in otherwise healthy people. If symptoms occur such as numbness, pain, loss of strength, change in skin color or texture, or loss of feeling in the fingers, hands, or joints, discontinue the use of this tool and seek medical attention. An anti vibration system does not guarantee the avoidance of these problems. Users who operate power tools on a continual and regular basis must monitor closely their physical condition and the condition of this tool.

The CHOKE helps to supply fuel to the engine to aid in cold starting. Activate the choke by moving choke lever to the desired position. See STARTING YOUR ENGINEforcomple testarting information.

PRIMER BULB

The PRIMER BULB removes airfrom the carburetor and fuel lines and fills them with fuel. This allows you to start the engine with fewer pulls on the starter rope. Activate the primer bulb by pressing it and allowing it to return to its original position.

FUELING ENGINE

WARNING:

when refueling. This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality synthetic 2-cycle aircooled engine oil designed to be mixed at a ratio of 40:1. Mix gasolineandoilataratioof40:1. A 40:1 ratio is obtained by mixing 3.2 ounces (95 ml)of oil with 1gallon(4liters)of unleaded gasoline. DO NOT USE automotive oil or boat oil. These oils will cause engine damage. When mixing fuel, follow instructions printed on container.Once oil is added togasoline, shakecontainermomentarilytoassurethat thefuelisthoroughlymixed.Alwaysread and follow the safety rules relating to fuel before fueling your unit.

Remove fuel cap slowly

IMPORTANT

Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, empty the fuel system before storage for 30 days or longer.Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

WARNING:

making idle speed adjustments. The blade will be moving during most of this procedure. Wear your protective equipment and observe all safety precautions. When making adjustments, use a screwdriver short enough to keep your hands behind the handguard and away from the blade. After making adjustments, the blade must not moveatidlespeed.

The carburetor has been carefully set at the factory. Adjustments may benecessary if you notice any of the following conditions:

Engine will not idle when the throttle is re-

leased. The blade moves at idle.

Keep others away when making idle speed adjustments. Make adjustments with the unit resting on a level surface free of debris that can be caught in the hedge trimmer blade. Serious injury to the operator and others can occur if the carburetor is not properly adjusted. Keep all parts of your body away from the blade and muffler.

Keep others away when

Idle Speed Adjustment

Allow engine to idle. Adjust speed until engine runswithout blade moving (idle toofast) orengine stalling (idle speed too slow).

Turn idle speed screw clockwise to in-

crease engine speed if engine stalls ordies. Turn idle speed screw counterclockwise to

decrease engine speed if the blade moves at idle.
