WARNING CONSIDERING HANDLING OF FUEL

a. The engine of this product is designed to run on a mixed

fuel which contains highly flammable gasoline. Never store

cans of fuel or refill the fuel tank in any place where here is

a boiler, stove, wood fire, electrical sparks, welding sparks,

or any other source of heat or fire which might ignite the

fuel.

b. Smoking while operating the product or refilling its fuel tank is extremely

dangerous. Always be sure to keep lit cigarettes away from the product

always.

c. When refilling the tank always turn off the engine first and take a careful

look around to make sure that there are no sparks or open flames

anywhere nearby before refueling.

d. If any fuel spillage occurs during refueling, use a dry rag to wipe up spills

before turning the engine back on again.

e. After refueling, screw the fuel cap back tightly onto the fuel tank and then

carry the product to a spot3ft. or more away from where it was refueled

before turning on the engine again.

BEFORE STARTING ENGINE

a. Check work area, the cutting object, and cutting direction. If there are

any obstacles, remove them.

b. Never start until you have a clear work area, secure footing, and a planned

retreat path from the failing tree.

c. Use caution and keep bystanders and animals out of the working area.

d. Inspect the machine and look for worn, loose, or damaged parts. Never

operate a machine that is damaged, improperly adjusted, or is not

completely and securely assembled. Make sure that the saw chain stops

moving when the throttle control trigger is released.

WHEN STARTING THE ENGINE

a. Always hold the machine firmly with both hands when the engine is running.

Use a firm grip with thumb and fingers encircling the handles.

b. Keep all parts of your body away from the machine when the engine is

running.

c. Before starting the engine, make sure the saw chain is not touching

anything.

OWNER’S MANUAL

WHEN OPERATING THE ENGINE

a. Keep the handles dry, clean, and free of oil or fuel mixture.

b. Never touch the muffler, spark plug, or other metal parts of the engine while

the engine is in operation or immediately after stopping the engine. Doing

so could result in serious burns or electrical shock.

c. Use extreme caution when cutting small size brush and saplings because

slender material may catch in the saw chain and be whipped toward you or

pull you off balance.

d. When cutting a limb that is under tension, be alert for spring back so that

you will not be struck when the tension in the wood fibers is released.

e. Check the tree for dead branches that could fall during the felling

operation.

f. Always shut off the engine before setting it down.

a. Kickback may occur when the nose or tip of the guide bar touches an

object, or when the wood closes in and pinches the saw chain in the cut.

Tip contact in some cases may cause a lightning fast reverse reaction,

kicking the guide bar up and back towards the operator. Either of these

reactions may cause you to lose control of saw which could result in

serious personal injury.

b. Do not rely exclusively on the safety devices built into your saw. As a chain

saw user you should take several steps to keep cutting jobs free from

accident or injury.

1)With a basic understanding of kickback, you can reduce or eliminate

the element of surprise. Sudden surprise contributes to accidents.

2)Keep a good grip on the saw with both hands, the right hand on the

rear handle, and the left hand on the front handle, when the engine is

running. Use a firm grip with thumbs and fingers encircling the chain

saw handles. A firm grip will help you reduce kickback and maintain

control of the saw.

3)Make certain that the area in which you are cutting is free from

obstructions. Don not let the nose of the guide bar contact a log,

branch, or any other obstructions which could be hit while you are

operating the saw.

4)Cut at high engine speeds.

5)Do not overreach or cut above shoulder height.
