AWTOOLS AW80391 power chainsaw accessory

AWTools AW80391 power chainsaw accessory is a replacement guide bar and chain set designed for AWTOOLS CS580 and CS620 chainsaws. The guide bar is made from a one-piece high-quality hardened steel with a powder-coated finish and a replaceable sprocket nose mounted on four high-tensile rivets. The chain uses hardened steel with semi-chisel cutters and a chrome-plated top plate to improve cutting speed and wear resistance. A roller bearing ensures precise guidance with minimal friction loss while an automatic chain lubrication system supports consistent operation. The set is supplied as a 400 mm depth unit with a total weight of approximately 1.3 kg.

Advantages

The one-piece hardened-steel guide bar combined with powder coating provides enhanced resistance to abrasion and high temperatures. A replaceable sprocket nose and roller bearing reduce friction and improve cutting precision. The chain’s semi-chisel cutters and chrome-plated top plate deliver faster cutting and increased wear resistance, while riveted tie straps enhance chain integrity and reduce the risk of breaking or stretching during use. The automatic lubrication system maintains consistent chain lubrication and contributes to longer component life.

Suitable for

• Replacement of worn guide bar and chain on AWTOOLS CS580 and CS620 chainsaws
• General woodcutting tasks including pruning and felling small to medium trees
• DIY projects and home maintenance involving timber cutting
• Professional light- to medium-duty cutting where reliable guidance and reduced friction are required

How to use

Fit the guide bar and chain set to an AWTOOLS CS580 or CS620 chainsaw following the manufacturer’s instructions for bar and chain replacement. Ensure the sprocket nose is correctly seated and that the four rivets securing the nose are intact. Adjust chain tension according to the chainsaw manual so the chain moves freely but does not sag from the guide bar. Fill the chainsaw’s oil reservoir and verify the automatic lubrication system is functioning before cutting. Inspect the chain and bar for damage or excessive wear prior to each use and replace components when necessary.

Usage recommendations

Use the AWTOOLS AW80391 set with the compatible AWTOOLS CS580/CS620 models and maintain regular lubrication and correct tension to extend service life. For best results, sharpen semi-chisel cutters as specified by the chainsaw manufacturer and avoid cutting materials with embedded metal or excessive dirt to reduce wear.
