STOPPING THE ENGINE

for a few minutes. 

2.  Set the switch to the “O” (STOP) position.

6. Sawing

1.  H and L needles are restricted within the number of 

turn as shown below. 

 

 

H needle :   1

 

1/2

 

± 

1/4

 

 

L needle  :  

 

2

 

± 

1/4

2.  Start the engine and allow it to warm up in low speed 

for a few minutes. 

3.  Turn the idle adjusting screw (T) counterclockwise 

so that the saw chain does not turn. If the idling 
speed is too slow, turn the screw clockwise. 

4.  Make a test cut and adjust the H needle for best 

cutting power, not for maximum speed. 

•  Before  proceeding  to  your  job, 

read the section “For Safe 
Operation”. It is recommended 
to first practice sawing easy 
logs. This also helps you get 
accustomed to your unit. 

•  Always  follow  the  safety  regu-

lations. The chain saw must 
only be used for cutting wood. 
It is forbidden to cut other 
types of material. Vibrations 
and kickback vary with differ-
ent materials and the require-
ments of the safety regulations 
would not be respected. Do 
not use the chain saw as a le-
ver for lifting, moving or split-
ting objects. Do not lock it over 
fixed stands. It is forbidden to 
hitch tools or applications to 
t h e  P T O  o t h e r  t h a n  t h o s e 
specified by the manufacturer. 

 •  It  is  not  necessary  to  force  the 

saw into the cut. Apply only 
light pressure while running the 
engine at full throttle. 

•  When  the  saw  chain  is  caught 

in the cut, do not attempt to pull 
it out by force, but use a wedge 
or a lever to open the way.

•  If the guide bar and saw chain 

becomes caught in wood while 
operating it, stop the engine. 
Do not pry the handle with ex-
cessive force. Use a wedge to 
remove the chain instead. 

■ 

GUARD AGAINST KICKBACK

To prevent kickback, do not use the tip of the guide 
bar for cutting.

■ 

FELLING A TREE

Notch cut

Felling cut

Felling direction

1.  Decide the felling direction considering the wind, 

lean of the tree, location of heavy branches, ease of 
completing the task 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. 

WARNING

When you fell a tree, be sure to warn neighboring work-
ers of the danger.
