Common questions
The R01201K is an 18V model. RIDGID lists a 4.0Ah 18V lithium-ion pack in the kit and says the tool is compatible with RIDGID 18V batteries.
Yes, the R01201K kit listing includes a 4.0Ah battery and charger. Check the product number carefully because the trimmer is also sold as a tool without the kit components.
Match the 18V platform and confirm the pack fits the R01201K using RIDGID's compatibility information. Use the approved charger and avoid relying on voltage alone for cross-brand fit.
RIDGID specifies a bump-feed head supplied with 0.095-inch trimmer line. Follow the manual when replacing or winding line.
