Stihl 00009302421 brush cutter/string trimmer accessory String trimmer line

STIHL 2.4 mm Round Quiet 83 m replacement cutting line is a trimmer line engineered for mowing grass and light vegetation with reduced cutting noise. The line has a round profile and 2.4 mm diameter, supplied on an 83-metre spool suitable for consumer string trimmers and brushcutters that accept round 2.4 mm line. The quiet formulation lowers operational noise compared with standard lines while maintaining cutting performance for routine garden maintenance tasks such as edging, weeding and trimming around obstacles.

Advantages

The round 2.4 mm profile provides smooth feeding and consistent cutting performance across typical garden grasses and light weeds. The quiet/low-noise formulation reduces audible cutting noise, making operation less intrusive in residential areas. An 83 m length on the spool offers extended run time between replacements and reduces the frequency of reloading for medium-sized gardens. Compatibility with common consumer trimmers that accept 2.4 mm round line ensures straightforward fit and use.

Suitable for

• Lawn edge trimming and mowing of fine to medium grass
• Weeding and clearing light vegetation around flowerbeds and paths
• Trimming around trees, fences and garden decorations
• Use with consumer string trimmers and brushcutters accepting 2.4 mm round line

Key specifications

• Profile: round
• Diameter: 2.4 mm
• Length: 83 m
• Noise-reducing/quiet formulation for lower cutting sound
• Intended vegetation: grass and light weeds

How to use

Fit the 83 m spool of 2.4 mm round line into the trimmer head following the trimmer manufacturer's instructions for line winding and securing. Ensure the line is threaded and anchored correctly to avoid feeding problems. Adjust cutting length and trimmer speed according to the vegetation being cut; use lower speed for fine grass and higher speed for denser patches. Replace the line when wear reduces cutting efficiency or the diameter is visibly reduced.

Usage recommendations

For best results, check your trimmer head compatibility with 2.4 mm round line before installation. Wear appropriate protective equipment and avoid using thick or woody stems that exceed the line's intended use to prevent premature wear. Store the spare spool in a dry, cool place to maintain line flexibility and performance.
