2. Move START/STOP switch(3) to STOP position.

Operating

When operating the unit, you should clip the shoulder strap onto the clamp, check for the following:

• Wear hearing protection, eye protection, head protection and heavy clothing.
• Extend your left arm and hold handlebar grip with your left hand.
• Hold throttle grip with your right hand with finger on throttle trigger. Keep unit belowwaist level.
• Keep shoulder strap pad centered on your left shoulder and danger sign centered on your back.
• Maintain full weight of tool on your left shoulder.
• Without bending over, keep the blade or trimmer head near and parallel to the ground andnot crowded into material being cut.

RISK OF KICK-OUT (Blade Thrust)– T his reaction can only occur when using a bladedunit. Thissudden and violent reaction can cause serious injury. Please carefully review this section. It is important that you understand what causes Blade Kick-out, and how you can reduce the chanceofitoccurring. It is critical to understand how to remain in control of the unit if blade thrust occurs.

WHAT CAUSES KICK-OUT (Blade Thrust) – Blade Thrust can occur when the spinningbladecontacts an object that it cannot cut. This contact causes the blade to stop for an instant andthensuddenly move or “thrust” away from the object that was hit. The “thrusting” reaction canbeviolentenough to cause the operator to be propelled in any direction and lose control of the unit. Theuncontrolled unit can cause serious injury if the blade contacts the operator or others in the area.

WHEN KICKOUT OCCURS – Blade Thrust can occur without warning if the blade snags, stalls, orbinds. This is more likely to occur in areas where it is difficult to see the material being cut. Byusingthe unit properly, the occurrence of blade thrust will be reduced and the operator will be less likelytolose control.

• Cut only grass, weeds, and woody brush up to 1/2 inch (1 cm) in diameter with the blade. Do not
  let the blade contact material it cannot cut such as stumps, rocks, fences, metal, etc., or clustersofhard, woody brush having a diameter greater than 1/2 inch (1 cm).

• Keep the blade sharp. A dull blade is more likely to snag and thrust.

• Cut only at full throttle. The blade will have maximum cutting power and is less likelytobindorstall.

• “Feed” the blade deliberately and not too rapidly. The blade can thrust away if it is fedtoorapidly.

• Cut only from your left to your right. Cutting on right side of the shield will throwdebris awayfrom the operator.

• Use the shoulder strap and keep a firm grip on the unit with both hands. A properly adjustedshoulder strap will support the weight of the unit, freeing your arms and hands to control andguide the cutting motion.

• Keep feet comfortably spread apart and braced for a possible sudden, rapid thrust of unit. Donot
  overreach. Keep firm footing and balance.

• Keep blade below waist level; it will be easier to maintain control of unit.

• Do not raise the engine above your waist as the blade can come dangerously close to your body.

• Do not swing unit with such force that you are in danger of losing your balance.

Bring the engine to cutting speed before entering the material to be cut. If the blade does not turnwhen you squeeze the throttle trigger, make sure shaft is fully inserted into the engine.

Always release the throttle trigger and allow engine to return to idle speed when not cutting. Thebladeshould not turn while the engine is running at idle. If the blade turns at idle, do not use your unit. Refer to contact customer service.

Maintain good firm footing while using the unit. Cut while swinging the upper part of your bodyfromleft to right.As you move forward to the next area to cut, be sure to maintain your balance andfooting.

MAINTENANCE

WARNING: Disconnect the spark plug before performing any maintenance.

Check For Damaged Or Worn Parts

Contact customer service for replacement of damaged or worn parts.

ON/OFF Switch – Ensure ON/OFF switch functions properly by pushing and releasing the switch. Make sure engine stops. Wait 5 seconds before attempting to restart unit to allowswitch toreset. Restart engine and continue.
Fuel Tank – Immediately discontinue use of unit if fuel tank shows signs of damage or leaks.
Debris Shield – Discontinue use of unit if debris shield is damaged.

Clean Air Filter

A dirty air filter will decrease engine performance and increases fuel consumption and harmful emissions. It is important to clean the filter after every 5 hours of operation

1. 1. Clean the filter cover, and the area around it to keep dirt from falling into the carburetor chamberwhen removed.

2. Press the tabs on the air filter cover to remove the cover and air filter.
   NOTE: To avoid creating a fire hazard or producing harmful evaporate emissions, do not cleanfilterin gasoline or other flammable solvent.

3. Wash the filter in soap and water.

4. Allow the filter thoroughly dry be for reinstalling.

5. Replace parts.

Replace Spark Plug

Replacing the spark plug each year will help ensure that the engine starts easier, and runs better. Set
spark plug gap at 0.023”~0.028”(0.6~0.7 mm). The ignition timing is fixed and does not requireadjustment.

Storage

CAUTION: Perform the following steps after each use:

• Allow engine to cool before storing or transporting.
• Store unit and fuel in a well-ventilated area where fuel vapors cannot reach sparks or openflamesfrom water heaters, electric motors or switches, furnaces, etc.
• Store unit with all guards in place. Position unit so that any sharp object cannot accidentallycauseinjury.
• Store this unit and the fuel well out of the reach of children

Prepare your unit for storage at the end of season or if it will not be used for 30 days or more. If yourunit is to be stored for a period of time:

1. Clean the entire unit before lengthy storage.
2. Store in a clean dry area.

Fuel System

Adding fuel stabilizer helps to minimize the formation of fuel gum deposits during storage. Addstabilizer to the gasoline in the fuel tank and/or fuel storage container. Run the engine for at least 5minutes after adding to distribute stabilizer throughout the system.

Engine

1. Replace the spark plug with new one of recommended type.
2. Clean air filter.
