NOTE
The oil tank should become nearly empty by the time fuel is used up. Be sure to refill the oil tank every time
when refueling the unit.
ADJUSTING CARBURETOR (F14)
The carburetor on your unit has been factory adjusted, but may require fine
running due to change in operating condition. Before adjusting the carburetor,
make sure that provided are clean air/fuel filters and fresh, properly mixed
fuel. When adjusting, take the following steps:
NOTE
Be sure to adjust the carburetor with the bar chain attached.
1.
Stop engine and screw in both H and L needles until they stop. Never force. Then set them back the initial
number of turns as shown below.
H needle: 1 ⅜
L needle: 1 ¼
2.
Start engine and allow it to warm up at half-throttle.
3.
Turn L needle slowly clockwise to find a position where idling speed is maximum, then set the needle back
a quarter (1/4) turn counterclockwise.
4.
Turn idle adjusting screw (T) 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.

CARBURETOR 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 carburetor, and forming within the carburetor, and this in turn 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. Under normal circumstances, the product should be used in normal
operating mode, i.e. in the mode to which it is set at the time of shipment. However, when the possibility
exists that icing may occur, the unit should be set to operate in anti-freeze mode before use. (F15)
