I can't find a manual that is specific to that tool, but there is an online article, pretty basic, that seems to cover your level.
See here.
Most laser levels are self-leveling, to a degree. But you will have to set it up close to level, by using the bubble. Then turn it on and it will self level and project level laser dots for you to use for your layout, etc. If you have doubts, check with a standard four foot level and see how accurate the beams are. You'll soon set the level aside and depend on the laser. Just make sure the bubble is between the lines before relying on the laser beam.
A great time saver in my experience, setting cabinets and leveling floors, drop ceilings, etc. etc.
Beyond that, I think robotoolz is just a brand name for some company that used a Chinese manufacturer that pumps tools out and is unlikely to provide much in the way of support. (
See this link.) The robotoolz.com site seems to be defunct (see
here and
here.) I've seen identical lasers packaged with different company logos and colors and sold by Bosch, Porter-Cable, and others, for varying price. They're not bad tools, though, and you can usually pick them up relatively cheaply.
If you scan the ads at someplace like amazon.com and find an identical looking laser, you may be able to get a model number that would help you to find an instruction manual online.
(READ THIS:) But you're more likely in my opinion to be able to download the manual for a similar version from a viable company and find that the instructions pertain to your model as well. Compare yours to
this Bosch version, then check the Bosch website (
here, for example) for manuals. If that is in fact the right model, download the manual here.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
