Keep cutting equipment well lubricated and properly 
maintained!  A poorly lubricated chain is more likely to 
break and lead to increased wear on the bar, chain and 
drive sprocket.

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.
