## Questions & Answers

**Q: If you ran it wide open, how long will it run until a recharge is needed?**
A: About 15 minutes max. And do not recharge it while the battery is hot.

**Q: Is this trimmer very heavy...I am 5 ft. tall and cannot handle trimmers that are for people who are taller, and if it is overly heavy.**
A: The length of the trimmer is adjustable and is not heavy.

**Q: Does this come with line string to start you off or do you need to purchase this separately?**
A: It comes with minimal string - I'd say maybe 3 ft. on the spool.  There's a pack of three on Amazon - a generic brand - for @$10.  Just get those when you order.

**Q: Does the LST300 come with batery and charger?**
A: yes it does come with both...handy little tool, light weight & does a great job. the batteries don't last long, but my fence row has grown tremendously because my other died, but still great tool. takes app. 4 hrs to completely recharge. I also boutght an extra charger + battery. helps a lot.
