❓ Frequently Asked Questions

Q: What does "Expand-It" mean and what attachments are compatible?

A: The Expand-It system allows you to transform this string trimmer into multiple tools by swapping attachments. Compatible attachments include edger, pole saw, hedge trimmer, cultivator, blower, and more—all using the same powerhead, saving money and storage space.

Q: Does this open box RYOBI trimmer come with batteries and a charger?

A: Yes! This open box unit includes batteries. Open box items are inspected, tested, and verified to work like new, offering professional-grade performance at a value price with significant savings.

Q: How does a 40V cordless trimmer compare to gas-powered models?

A: RYOBI's 40V system delivers power comparable to gas trimmers without the hassle of mixing fuel, pull-starts, or engine maintenance. You get instant starts, quieter operation, zero emissions, and consistent power throughout the battery charge.

Q: What is the runtime on a full battery charge?

A: Runtime varies based on battery capacity and workload. With a 40V 4.0Ah battery, expect 30-45 minutes of continuous trimming. Higher capacity batteries (5.0Ah or 6.0Ah) provide extended runtime for larger yards.

Q: Can I use this trimmer for edging along sidewalks and driveways?

A: Absolutely! The 15-inch cutting swath and cordless maneuverability make it perfect for edging, trimming tight spaces, and maintaining clean lines along walkways, driveways, fences, and garden beds.

Q: Is the 15-inch cutting width sufficient for larger yards?

A: Yes! The 15-inch cutting swath provides an excellent balance between precision and coverage, making it ideal for residential yards up to 1 acre. The cordless design eliminates extension cord limitations for maximum mobility.

Q: What type of trimmer line does this use?

A: This RYOBI string trimmer uses standard 0.080-inch or 0.095-inch diameter trimmer line. The bump-feed head makes line advancement quick and easy during operation.

Q: Are RYOBI 40V batteries interchangeable with other RYOBI 40V tools?

A: Yes! All RYOBI 40V batteries work across the entire 40V tool platform, including mowers, blowers, chainsaws, and more. Build your cordless yard care system with one battery platform.

Q: What's the advantage of buying an open box string trimmer?

A: Open box units are customer returns or display models that have been professionally inspected, tested, and verified to meet original performance standards. You get the same quality and functionality at a discounted price—perfect for budget-conscious homeowners.

Q: Does this trimmer have variable speed control?

A: Yes! The variable speed trigger allows you to adjust power output for different tasks—use lower speeds for delicate trimming around flowers and higher speeds for thick grass and weeds.
