String trimmer line Stihl CF3 Pro

The Stihl CF3 Pro string trimmer line is designed for efficient grass and vegetation trimming with a 3 mm diameter and durable polyamide construction. This multicolour line provides reliable cutting performance for common garden maintenance tasks and is sold as a single piece to fit compatible handheld trimmers. The product balances wear resistance and flexibility to maintain a consistent trimming result across regular domestic and professional applications.

Advantages

The 3 mm polyamide filament offers a combination of strength and flexibility suitable for standard trimming jobs. Its multicolour finish helps with visibility during operation and makes line management easier when reloading. The material resists abrasion and performs consistently under typical outdoor conditions, reducing the need for frequent replacements while providing steady cutting power on grass, light weeds and edge work.

How to use

Ensure the trimmer is switched off and the ignition is disabled or battery removed before replacing the line. Follow the trimmer manufacturer's instructions to open the cutting head, wind the CF3 Pro line onto the spool according to the indicated direction, and secure the line ends in the spool notches. Reassemble the head, check that the line protrudes evenly, and test at low speed to confirm correct installation before normal operation.

Usage recommendations

Use the 3 mm CF3 Pro line on trimmers specified by the equipment manufacturer for this diameter. Avoid cutting large woody stems or hard materials that can accelerate wear. Regularly inspect the line for wear and replace it when performance drops. For best results, operate at the trimmer’s recommended RPM and store the line in a cool, dry place away from direct sunlight.
