If chain brake functions properly, turn the engine off and return the chain brake to the 
disengaged position. 

9.7 

Saw chain / bar lubrication 

Adequate  lubrication  of  the  saw  chain  is  essential  at  all  times  to  minimize  friction  with  the 
guide  bar.  Never  starve  the  bar  and  chain  of  oil.  Running  the  saw  with  too  little  oil  will 
decrease  cutting  efficiency,  shorten  saw  chain  life,  cause  rapid  dulling  of  chain,  and  cause 
excessive wear of bar from overheating. Too little oil is evidenced by smoke, bar discoloration 
or pitch build-up. 

Note: saw chain stretches during use, particularly when it is new, and it will 
occasionally  be  necessary  to  adjust  and  tighten  it.  New  chain  will  require 
adjustment after about 5 minutes of operation. 

9.8 

Automatic oiler 

Your  chain  saw  is  equipped  with  an  automatic  clutch  driven  oiler  system.  The  oiler 
automatically  delivers  the  proper  amount  of  oil  to  the  bar  and  chain.  As  the  engine  speed 
increases, so does the oil flow to the bar pad. 

Do  not  adjust  the  chain  lubrication  system  unless  the  motor  has  been 
turned off. 

The chain lubrication system has been preset to medium oil flow at the factory. The flow can 
be adjusted if necessary. 

 To adjust the oil flow, turn the adjusting screw at the bottom side of the housing (Fig 11) 

(19) 

 Turning it clockwise reduces the oil flow, while turning it counterclockwise increases the oil.

General cutting instructions 

9.9.1 

Felling 

Felling is the term for cutting down a tree. Small trees up to 6-7 inches (15-18cm) in diameter 
are  usually  cut  in  a  single  cut.  Larger  trees  require  notch  cuts.  Notch  cuts  determine  the 
direction the tree will fall. 

Felling a tree: 

Warning:  a  retreat  path  (A)  should  be  planned  and  cleared  as  necessary 
before cuts are started. The retreat path should extend back and diagonally 
to the rear of the expected line of fall, as illustrated in fig. 12a 

Caution:  if  felling  a  tree  on  sloping  ground,  the  chain  saw operator  should 
keep  on  the  uphill  side  of  the  terrain,  as  the  tree  is  likely  to  roll  or  slide 
downhill after it is felled. 

Note: direction of fall (B) is controlled by the notching cut. Before any cuts 
are  made,  consider  the  location  of  larger  branches  and  natural  lean  of  the 
tree to determine the way the tree will fall. 

Warning: do not cut down a tree during high- or changing winds or if there 
is a danger to property. Consult a tree professional. Do not cut down a tree 
if there is a danger of striking utility wires; notify the utility company before 
making any cuts.
