What cutting line should I use with this head and how does it perform?

The AutoCut 2-2 accepts 2.0 mm diameter line, a common size that balances durability and flexibility for grass and light weed trimming. Using the recommended line size ensures consistent feeding and reduces jams, helping the trimmer cut evenly across lawns and edges.

• Suitable for grass, light weeds, and general edging
• Proper line size prevents feeding problems

How long will this trimmer head last before replacement?

Longevity depends on use and material contact: frequent heavy-duty jobs or hitting hard surfaces will wear the head and line faster than occasional lawn maintenance. Treat it as a consumable wear part — inspect regularly and replace the head when mounting points or line feed features show significant wear.

• Durability varies with workload and terrain
• Inspect head after impact or heavy use
• Replace when line feed or housing is damaged
• Keep a spare head on hand for uninterrupted work
