14 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 
of control, which, in turn, may cause 
serious or fatal injury. An understanding 
of the causes of these reactive forces 
may help you avoid the element of 
surprise and loss of control. Surprise 
contributes to accidents.
The most common reactive forces are:
–kickback,
–pushback,
–pull-in.

WARNING
The computer derived angles of the 
chain saw kickback standard may bear 
no relationship to actual kickback bar 
rotation angles that may occur in real life 
cutting situations.
In addition, features designed to reduce 
kickback injuries may lose some of their 
effectiveness when they are no longer in 
their original condition, especially if they 
have been improperly maintained. 
Compliance with the chain saw kickback 
standard does not automatically mean

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 chain 
saw equipped with a Quickstop chain 
brake will disable the activation 
mechanism of the chain brake.

Low Kickback Saw Chain
Some types of saw chains have 
specially designed components to 
reduce the force of nose contact 
kickback. STIHL has developed low 
kickback saw chain for your chain saw.

ANSI/OPEI B175.1-2012 when tested 
according to the provisions...

A=Pull-in
Pull-in occurs when the saw 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 saw chain pulls the chain 
saw forward and may cause the 
operator to lose control.
Pull-in frequently occurs when the 
bumper spike of the chain saw is not 
held securely against the tree or limb 
and when the saw chain is not rotating at 
full speed before it contacts the wood.
WARNING
Use extreme...
