GENERAL SAFETY PRECAUTIONS

Cutting equipment designed to reduce kickback

WARNING! Faulty cutting equipment or ! the wrong combination of bar and saw

chain increases the risk of kickback! Only use the bar/saw chain combinations we recommend, and follow the ﬁling instructions. See instructions under the heading Technical data.

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.

Bar

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

Chain

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

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

WARNING! Any contact with a rotating ! saw chain can cause extremely serious

injuries.

Some terms that describe the bar and chain

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.

Bar

•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

•Chain pitch (inches)

•Drive link width (mm/inches)

•Number of drive links.
