The only way to avoid kickback is to make sure that the 
kickback zone of the bar never touches anything.

By using cutting equipment with ”built-in” kickback 
reduction and keeping the chain sharp and well-
maintained you can reduce the effects of kickback.

The smaller the tip radius the lower the chance of 
kickback.

A chain is made up of a number of links, which are 
available in standard and low-kickback versions.

To maintain the safety features of the cutting equipment, 
you should replace a worn or damaged bar or chain with 
a bar and chain combinations recommended by 
Husqvarna. See instructions under the heading Technical 
Data for a list of replacement bar and chain combinations 
we recommend.

•

Length (inches/cm)

•

Number of teeth on bar tip sprocket (T).

•

Chain pitch (inches). The spacing between the drive 
links of the chain must match the spacing of the teeth 
on the bar tip sprocket and drive sprocket.

•

Number of drive links. The number of drive links is 
determined by the length of the bar, the chain pitch 
and the number of teeth on the bar tip sprocket.

•

Bar groove width (inches/mm). The groove in the bar 
must match the width of the chain drive links.

•

Chain oil hole and hole for chain tensioner. The bar 
must be matched to the chain saw design.

•

Chain pitch (inches)

•

Drive link width (mm/inches)

•

Number of drive links.

IMPORTANT! No saw chain design eliminates the 
danger of kickback.
