starting. Stop the engine immediately if 
you are approached.
WARNING
Even though bystanders should be kept 
away from the running saw, never work 
alone. Keep within calling distance of 
others in case help is needed.

11 In the event of an emergency, switch off 
the engine immediately – move the slide 
control / stop switch to 0 or STOP.
WARNING
Always stop the engine before putting a 
chain saw down.
WARNING
The saw chain continues to move for a 
short period after the throttle trigger is 
released (flywheel effect).
Accelerating the engine while the saw 
chain is blocked increases the load and 
will cause the clutch to slip continuously. 
This may occur if...

WARNING
Reactive Forces including Kickback
WARNING
Reactive forces may occur any time the 
chain is rotating. Reactive forces can 
cause serious personal injury.The powerful force used to cut wood can 
be reversed and work against the 
operator. If the rotating chain is suddenly 
stopped by contact with any solid object 
such as a log or branch or is pinched, the 
reactive forces may occur instantly. 
These reactive forces may result in loss...

13 the bar and chain contact the object, the 
angle of contact, the condition of the 
chain and other factors.
The type of bar and saw chain you use 
is an important factor in the occurrence 
and force of the kickback reaction. Some 
STIHL bar and chain types are designed 
to reduce kickback forces. STIHL 
recommends the use of reduced 
kickback bars and low kickback chains.

the bar nose even without hand contact. 
See the chapter entitled "Chain Brake" 
of your instruction manual.
WARNING
Never operate your chain saw without a 
front hand guard. In a kickback situation 
this guard helps protect your left hand 
and other parts of your body. In addition, 
removal of the hand guard on a saw 
equipped with a Quickstop chain brake 
will deactivate the chain brake....

Therefore, always observe all safety 
precautions to avoid kickback situations.
Low Kickback Chain
Some types of saw chain have specially 
designed components to reduce the 
force of nose contact kickback. STIHL 
has developed low kickback chain for 
your powerhead.
"Low kickback saw chain" is a chain 
which has met the kickback 
performance requirements of § 5.11.2.4 
of ANSI B 175.1-2000...

16 A = Pull-in
Pull-in occurs when the chain on the 
bottom of the bar is suddenly stopped 
when it is pinched, caught or encounters 
a foreign object in the wood. The 
reaction of the chain pulls the saw 
forward and may cause the operator to 
lose control.
Pull-in frequently occurs when the 
bumper spike of the saw is not held 
securely against the tree or limb and 
when the chain is not rotating at full 
speed before it contacts the wood....

direction of the fall
For a conventional cut:
NProperly place felling notch 
perpendicular to the line of fall, 
close to the ground.
NCut down at approx. 45° angle to a 
depth of about 1/5 to 1/4 of the trunk 
diameter.
NMake second cut horizontal.
