Frequently Asked Questions
Will it fit my tool / vehicle?
The compatibility list is in the title and specs — check your model against it before ordering. Model numbers matter here more than brand names.
What voltage does it run on?
30V, which is standard household here. No adapter, no converter, nothing extra to buy.
Is it built to last?
Metal where it counts and a housing that takes shop knocks. It is a working tool, not a display piece.
What is in the box?
The listing lists exactly what ships with it. Anything not listed is not included.
Is it easy to use?
Straightforward once it is in your hand — no special technique beyond what the instructions show.
