WARNING

Do not start the engine while hanging the chain

saw with a hand. The saw chain may touch your

body. It’s very dangerous.

When the engine has ignited first, push in

the choke knob and pull the starter again to

start the engine.

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 figure. (F13)

CHAIN OIL

The chain oil flow 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 refill the oil tank

every time when refuelling the unit.

ADJUSTING CARBURETTOR (F15)

The carburettor on your unit has been factory

adjusted, but may require fine turning due to

change in operating conditions.

Before adjusting the carburettor, 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 carburettor with the bar

chain attached,

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

Start engine and allow it to warm up at half-

throttle.

Turn L needle slowly clockwise to find a

position where idling speed is maximum, then

set the needle back a quarter (1/4) turn counter-

clockwise.

Turn idle adjusting screw (3) counter-

clockwise so that saw chain does not turn.

If idling speed is too slow, turn the screw

clockwise.

Make a test cut and adjust the H needle for

best cutting power, not for maximum speed.

L needle.

H needle.

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.
