through "V"-shaped supports on top of a 
sawhorse. Never permit another person 
to hold the log. Never hold the log with 
your leg or foot.Logs under strain:
Risk of pinching! Always start relieving 
cut (1) at compression side.Then make 
bucking cut (2) at tension side. If the saw 
pinches, stop the engine and remove it 
from the log.
Only properly trained professionals 
should work in an area where the logs, 
limbs and roots are tangled....

23 Felling Cut for Large Diameter Trees
WARNING
Felling a tree that has a diameter greater 
than the length of the guide bar requires 
use of either the sectioning felling cut or 
plunge-cut method. These methods are 
extremely dangerous because they 
involve the use of the nose of the guide 
bar and can result in kickback. Only 
properly trained professionals should 
attempt these techniques.
Sectioning Method
For the sectioning method make the first 
part of the felling cut with the...

WARNING
In order to reduce the risk of personal 
injury, never stand directly behind the 
tree when it is about to fall, since part of 
the trunk may split and come back 
towards the operator (barber-chairing), 
or the tree may jump backwards off the 
stump. Always keep to the side of the 
falling tree. When the tree starts to fall, 
withdraw the bar, shut off the engine and 
walk away on the preplanned escape 
path. Watch out for falling limbs.
WARNING
Be extremely careful with...

25 Keep the chain, bar and sprocket clean; 
replace worn sprockets or chains. Keep 
the chain sharp. You can spot a dull 
chain when easy-to-cut wood becomes 
hard to cut and burn marks appear on 
the wood. Keep the chain at proper 
tension.
Tighten all nuts, bolts and screws after 
each use.
WARNING
In order for the chain brake on your 
STIHL chain saw to properly perform its 
function of reducing the risk of kickback 
and other injuries, it must be properly 
maintained. Like an...

Chain scabbard
Your saw comes standard with a chain 
scabbard that matches the cutting 
attachment.
If you use guide bars of different lengths 
on the saw, the length of the chain 
scabbard must be matched to the guide 
bar to reduce the risk of injury. It should 
cover the full length of the guide bar.
The length of the matching guide bars is 
marked on the side of the chain 
scabbard.
Removing the chain sprocket cover
NUnscrew the nut and remove the 
chain sprocket cover.

slide in the locating hole (2) –- place 
the chain over the sprocket (3) at 
the same time.
NTurn the tensioning screw (4) 
clockwise until there is very little 
chain sag on the underside of the

28 This engine is certified to operate on 
unleaded gasoline and STIHL two-
stroke engine oil at a mix ratio of 50:1.
Your engine requires a mixture of high-
quality gasoline and two-stroke air 
cooled engine oil.
Use mid-grade unleaded gasoline with a 
minimum octane rating of 89 (R+M/2) 
and no more than 10% ethanol content.
Fuel with a lower octane rating may 
increase engine temperatures. This, in 
turn, increases the risk of piston seizure 
and damage to the engine.
The chemical...
