Replacement chainsaw guide bar DeWalt BD-DT20661 with a 46 cm cutting length is a precision-made guide component intended for compatible chainsaws. The bar provides the mounting surface and groove for the saw chain, ensuring correct chain alignment and supporting stable cutting performance for general purpose tasks such as felling, limbing and processing firewood when installed on a matching DeWalt or compatible model saw.

Advantages

The guide bar is manufactured to DeWalt quality standards to deliver consistent chain tracking and reduced vibration during operation. Its 46 cm length balances cutting capacity and maneuverability for both larger logs and everyday tasks. The hardened nose and reinforced rail design improve wear resistance and extend service life under normal working conditions. The bar is shaped to simplify chain installation and tensioning, enabling accurate fitment and reliable performance when paired with the correct chain and sprocket.

How to use

Before fitting, ensure the chainsaw is switched off, the spark plug wire is disconnected (for petrol models) or the battery is removed (for battery models). Remove the side cover and existing bar and chain according to the saw manufacturer's instructions. Position the replacement guide bar on the mounting studs, fit the correct length chain into the bar groove and loop it around the drive sprocket, then adjust chain tension to the manufacturer’s recommended specification. Refit the side cover and secure fasteners, then perform a tension recheck after a short run-in period. Use appropriate personal protective equipment and follow the chainsaw manufacturer's safety and maintenance guidelines.

Usage recommendations

Use chains lubricants and maintain correct chain tension to reduce wear on the guide bar. Inspect the bar groove and nose for damage regularly; rotate or replace the bar if excessive wear or deformation is present. Match the guide bar with a correctly sized chain and compatible sprocket to ensure safe, efficient cutting performance.
