d. If any fuel spillage occurs during refueling, use a dry rag to w

ipe 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 spot 3 m or more away from where it was refueled before turning on the engine.

Check working place, the cutting object and cutting direction. If there is obstacle, remove it. Never start cutting until you have a clear work area, secure footing and a planned retreat path from the falling tree.

Use caution and keep bystanders and

animals out of the working area whose diameter is 2.5 times of the cutting object. Inspect the machine for worn, loose, or damaged parts. Never operate

the 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.

Always hold the machine firmly with both hands when the engine is running. Use a firm grip with thumb and fingers encircling the handles. Keep a

ll parts of your body away from the machine when the engine

running.

WORKING CONSIDERING HANDLING OF FUEL

BEFORE STARTING ENGINE

WHEN STARTING THE ENGINE

Page 7

Before starting the engine, make sure the saw chain is not contacting anything.

Keep the handles dry, clean and free of oil or fuel mixture. Never touch the muffler, spark plug or other metallic parts of the engine while the engine is in operation or immediately after stopping the engine. Doing so could result in serious bums or electrical shock.

Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance.

When cutting a limb that is under tension,

be alert for spring back to that you won’t be struck when the tension in the wood fibers is released check the tree for dead branches that could fall during the felling operation.

Always shut of the engine before setting it down.

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 oper

ator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclusively on the safely devices built into your saw. As a chain saw user you should take several steps to keep cutting jobs free from accident or injury.

With a basic understanding of kickback you can reduce or eliminate the element of surpr

ise. Sudden surprise contributes to accidents. 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. Make certain that the area in which you are cutting is free from obstructions Do not let the nose of the guide bar contact a log, branch, or any othe

r obstructions which could be hit while you are operating the saw. Cut at high engine speeda.

This machine is equipped with an automatic brake to stop saw chain r

otation upon occurrence of kickback while in saw cutting operation. The brake is automatically operated by inertial force which acts on the weight fitted inside the front guard. This brake can also be operated manually with the front guard turned down to the guide bar.(F16) To release brake, pull up the front guard toward the front handle till”click”sound is head.

Be sure to confirm brake operation on the daily inspection How to confirm (1)Turn off the engine. (2)Holding the chain saw horizontally, release your hand from the front handle, hit the tip of the guide bar to a st

ump or a piece of wood, and confirm brake

operation. Operating level varies by bar size.(F17) In case the brake is not effective, ask our dealer inspection and repairing. The engine, If being dept rotated to high speed with the brake engaged, heats the clutch, causing a trouble, When the brake is operated while in operation, immediately release your fingers from the throttle lever and keep the engine idling.

WARNING

Page 16

It is extremely important that the chain brake be checked for proper operation before each use and that the chain be sharp in order to maintain the kickback safety level of this saw. Removal of the saf ety dev ices. In adequate mainten ance, or incorrect replacement of the bar or chain may increase the risk or serious personal injury due to kickback.

Decide the felling direction considering the wind, lean of the tree, location of heavy branches, ease of job after felling and other factors While clearing the area aro

und the tree, arrange a good foothold and retreat path. Make a notch cut one-third of the way into the tree on the felling side.

Make a felling cut from the opposite side of the notch and at a level slightly higher than the bottom of the notch.

Before starting work, check the direction of bending force inside the log to be cut. always finish cutting from the opposite side of bending direction to prevent

FELLING A TREE(F20)
