1.2 Kickback Prevention and Safety Features

Kickback is a sudden, violent reaction of the chainsaw. It occurs when the chain’s upper tip strikes an object. The Husqvarna 455 features an inertia-activated chain brake to reduce kickback risks. Always engage the chain brake when starting the saw or moving with the engine running. Use bars and chains that meet ANSI B 175.1-2000 standards. Ensure the chain is sharp and correctly tensioned. Avoid cutting small-diameter branches above shoulder height. Maintain control and proper stance, with the saw close to your body.

• Engage the chain brake when starting.
• Use approved bars and chains.
• Avoid cutting above shoulder height.

Regular maintenance and correct techniques further prevent kickback incidents.
