e. After refuelling, screw the fuel cap back tightly onto the fuel tank and then carry the product to a spot 3m or more away from where it was refuelled before turning on the engine.

BEFORE STARTING ENGINE

• Check working place, the cutting object and cutting direction. It 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.

WHEN STARTING THE ENGINE

• Always hold the machine rmly with both hands when the engine is running.

• Use a rm grip with thumb and ngers encircling the handles.

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

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

OPERATION

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

• Never touch the mufer, 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 burns or electrical shock. Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped towards you or pull you off balance.

• 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 bres 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 SAFETY PRECAUTIONS FOR CHAIN SAW USERS

WARNING

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 lightningfast reverse reaction, kicking the guide bar up and back toward the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward 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 upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your 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;

·Inspect the machine for worn,

loose, or damaged parts. Never

the choke knob and pull the starter again to start the engine.

9. Allow the engine to warm up with the throttle lever pulled slightly.

WARNING

Keep clear of the saw chain as it will start rotating upon starting of engine.

CHECKING OIL SUPPLY

After starting the engine, run the chain at medium speed and see if chain oil is scattered

off as shown in the gure. (F13)

CHAIN OIL

The chain oil ow can be changed by inserting

a screwdriver in the hole on bottom of the clutch side. Adjust according to your work conditions. (F14)

ADJUSTER

The oil tank should become nearly empty by the

time fuel is used up. Be sure to rell the oil tank

every time when refuelling the unit.

ADJUSTING CARBURETTOR (F15)

The carburettor on your unit has been factory

adjusted, but may require ne turning due to

change in operating conditions. Before adjusting the carburettor, make sure

that provided are clean air/fuel lters and fresh,

properly mixed fuel. When adjusting, take the following steps:

NOTE

Be sure to adjust the carburettor with the bar chain attached,

1. Stop engine and screw in both H and L needles until they stop. Never force. Set them back the initial number of turns as shown below.

H needle: 1±⅜

L needle: 13/4±¼

2. Start engine and allow it to warm up at halfthrottle.

3. Turn L needle slowly clockwise to nd a

position where idling speed is maximum, then set the needle back a quarter (1/4) turn counterclockwise.

4. Turn idle adjusting screw (3) counterclockwise so that saw chain does not turn. If idling speed is too slow, turn the screw clockwise.

5. Make a test cut and adjust the H needle for best cutting power, not for maximum speed.

1. L needle.

2. H needle.

3. Idle adjusting screw.

CARBURETTOR ANTI-FREEZE MECHANISM

Operating the chain saw in temperatures of 0-5°C at times of high humidity may result in ice forming within the carburettor, and this in time may cause the output power of the engine to be reduced or for the engine to fail to operate smoothly. This product has accordingly been designed with a ventilation hatch the back of the air cleaner cover to allow warm air to be supplied to the engine and to thereby prevent icing from occurring. (For some other models, the hot air intake can be adjusted by the wind cover) Under normal circumstances the product should be used in normal operating mode. However when the possibility exists that icing may occur, the unit should be set to operate in anti-freeze mode before use.

■FELLING A TREE (F20)

1.Decide the felling direction considering

the wind, lean of the tree, location of heavy

branches, ease of job after felling and other

factors.

2.While clearing the area around the tree,

arrange a good foothold and retreat path.

3.Make a notch cut one-third of the way into

the tree on the felling side.

4.Make a felling cut from the opposite side

of the notch and at a level slightly higher

than the bottom of the notch.
