WARNING

to sound level and hours of operations for the product.

■ BEFORE STARTING THE ENGINE

1. The area within a perimeter of 15 m of

the person using the product should be considered a hazardous area into which no one should enter. If necessary, yellow warning rope, warning signs should be placed around the perimeter of the area. When work is to be performed simultaneously by two or more persons, care should also be taken to constantly look around or otherwise check for the presence and locations of other people working so as to maintain a distance between each person sufficient to ensure safety.

2. Check the condition of working area to

avoid any accident by hitting hidden obstacles such as stumps, stones, cans, or broken glass.

Remove any obstacle before beginning work.

3. Inspect the entire unit for loose

fasteners and fuel leakage. Make sure that the cutting attachment is properly installed and securely fastened.

4. Be sure the cutting attachment guard is

firmly attached in place.

5. Always use the harness. Adjust the

harness for comfort before starting the engine. The harness should be adjusted so the left hand can comfortably hold the handlebar grip approximately waist high.

■ STARTING THE ENGINE

1. Keep bystanders and animals at least

15 m away from the operating point. If you are approached, immediately stop the engine.

2. The product is equipped with a

centrifugal clutch mechanism, so the cutting attachment begins to rotate as soon as the engine is started by putting the throttle trigger into the start position. When starting the engine, place the product onto the ground in a flat clear area and hold it firmly in place

IMPORTANT

so as to ensure that neither the cutting part nor the throttle trigger come into contact with any obstacle when the engine starts.

Never place the throttle trigger into the high-speed position when starting the engine.

3. After starting the engine, check to make sure that the cutting attachment stops rotating when the throttle is moved fully back to its original position. If it continues to rotate even after the throttle trigger has been moved fully back, turn off the engine and take the unit to your authorized ZENOAH servicing dealer for repair.

■ USING THE PRODUCT

Cut only materials recommended by the manufacturer. And use only for tasks explained in the manual.

1. Grip the handles firmly with both hands using your whole hand. Place your feet slightly apart (slightly further apart than the width of your shoulders) so that your weight is distributed evenly across both legs, and always be sure to maintain a steady, even posture while working.

2. Keep cutting attachment below waist level.

3. Maintain the speed of the engine at the level required to perform cutting work, and never raise the speed of the engine above the level necessary.

4. If the unit starts to shake or vibrate, turn off the engine and check the whole unit. Do not use it until the trouble has been properly corrected.

5. Keep all parts of your body away from rotating cutting attachment and hot surfaces.

6. Never touch the muffler, spark plug, or other metallic parts of the engine while the engine is in operation or immediately after shutting down the engine. Doing so could result in

WARNING

■ HANDLING FUEL

1. The engine of the ZENOAH product is designed to run on a mixed fuel, which contains highly flammable gasoline. Never store cans of fuel or refill the tank of the unit in any place where there is a boiler, stove, wood fire, electrical sparks, welding sparks, or any other source of heat or fire which might ignite the fuel.

2. Never smoke while operating the unit or refilling its fuel tank.

3. When refilling the tank, always turn off the engine and allow it to cool down. Take a careful look around to make sure that there are no sparks or open flames anywhere nearby before refueling.

4. Wipe spilled fuel completely using a dry rag if any fuel spillage occurs during refueling.

5. After refueling, screw the fuel cap back tightly onto the fuel tank and then carry the unit to a spot 3 m or more away from where it was refueled before turning on the engine.

■ TRANSPORTATION

1. When hand-carrying the product, cover over the cutting part if necessary, lift up the product and carry it paying attention to the blade.

2. Never transport the product over rough roads over long distances by vehicle without removing all fuel from the fuel tank. If doing so, fuel might leak from the tank during transport.

■ CONTROLLING BLADE THRUST

Blade thrust can cause serious personal injury. Carefully study this section. It is important that you understand what causes blade thrust, how you can reduce the chance of blade thrust and how you can remain in control of the unit if blade thrust does occur.

1. What causes blade thrust:

Blade thrust can occur when the moving blade contacts an object that it cannot cut.

WARNING

4. Safety precautions

This contact causes the blade to stop for an instant and then suddenly move or ”bounce” away from the object that was hit. The operator can lose control of the unit and the blade can cause serious personal injury to the operator or any person nearby if the blade contacts any part of the body.

2. How you can reduce the chance of blade thrust:

(1) Recognize that blade thrust can

happen. By understanding and knowing about bounce, you can help eliminate the element of surprise.

(2) Cut fibrous weeds and grass only. Do

not let the blade contact materials it cannot cut such as hard, woody vines and brush or rocks, fences, metal, etc

(3) Be extra prepared for blade thrust if

you must cut where you cannot see the blade making contact such as in areas of dense growth.

(4) Keep the blade sharp. A dull blade

increase the chance of blade thrust.

(5) Avoid feeding the blade too rapidly.

The blade can bounce away from material being cut if the blade is fed

faster than its cutting capability. (6) Cut only from your right to your left. (7) Keep your path of advance clear of

material that has been cut and other

debris.

3. How you can maintain the best

control:

(1) Keep a good, firm grip on the unit with

both hands. A firm grip can help

neutralize bounce. Keep your right

and left hands completely around the

respective handles. (2) Keep both feet spread apart in a

comfortable stance and yet braced for

the possibility that the unit could

bounce. Do not overreach. Keep firm

footing and balance.
