and see if chain oil is scattered off as shown in the figure.
The chain oil flow can be changed by inserting a scre-
wdriver in the hole on bottom of the clutch side. Adjust
according to your work conditions.

Adjusting carburetor
The carburetor on your unit has been factory adjusted,
but may require fine tuning due to change in operating
conditions. Before adjusting the carburetor, make sure
that provided are clean air/fuel filters and fresh, properly
mixed fuel.
When adjusting, take the following steps:
IMPORTANT
Be sure to adjust the carburetor with the bar chain at-
tached.
1. Stop engine and screw in both the H and L needles
until they stop. Never force them. Then set them back
the initial number of turn as shown below.
H needle: 3 / 4 + 3 / 8
L needle: 1 1 / 2 + 1 / 4
2. Start engine and allow it to warm up in low speed for
a few minutes.
3. Turn the 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) counter-clockwise so
that saw chain does not turn. If idling speed is too
slow, turn the screw clockwise.
5. Make a test cut adjust the H needle for best cutting
power, not for maximum speed.
Chain brake
This machine is equipped with and automatic brake to
stop saw chain rotation upon occur- ence of kickback
during saw cutting. 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.
