The Laser Gay - er - I mean - Laser Straight is a small device designed to be stuck on walls to help assure the straightness of pictures, chair rails, and similar articles.

It comes with two small packets of "Blu Tack" adhesive to affix it to the wall without leaving marks, and two pins for when the Blu Tack seems like it may not hold - a kind of extra security.

What it does is project a straight red line in front of wherever you place it, for up to 50 feet.


SIZE



To use the product, feed it first (see directly below), and then you'll be ready to rock.

Remove one of the pins from the battery compartment for later use if needed.

Remove two small pieces of Blu Tack adhesive from the little pack it comes in, and affix them to the bottom of the Laser Straight. Apply the adhesive to each end of the bottom of the Laser Straight as shown in the provided instructional material.

Place the Laser Straight on a clean dry area of the wall to the side of where you'll be working.

Adjust the Laser Straight until the horizontal bubble is level (if aligning horizontal objects) or the vertical bubble is level (if aligning vertical objects).

Once the bubble is level, press the Laser Straight firmly against the wall. Your Laser Straight will stick to the wall. You can make MINOR adjustments to readjust the bubble if necessary.

Press and release the grey triangular button on the side of the Laser Straight to turn the laser on. A red line should now be visible along the entire length of the wall in front of the unit. This line is not bright, but it should be visible in normal room illumination.

For extra safety, use the pin (drywall and soft wood only) to secure the Laser Straight to the wall; pushing the pin through the hole on the back of the Laser Straight.

I'm not a carpenter, and I don't play one on TV or on the internet, so please read the instructional material that comes with the Laser Straight in case I missed something very important.



Turn the Laser Straight upside-down, with the laser facing forward. Pull back slightly on the clip on the front of the battery door, lift the door away, throw it in the {vulgar term for feces}bowl, and flush it away...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Remove the two used AAA cells if necessary, and dispose of or recycle them as you see fit.

Insert two new AAA cells in the battery compartment, orienting the cells so the flat-end (-) negative of each one faces a spring for it in each chamber.

Place the battery door back on, pressing down on the clip-end so it clicks, and there, you're finished.
Aren't you glad you didn't flush that battery door down the toilet now?

Current consumption measures 20.11mA on my DMM's 40mA scale.



This is a laser levelling device, not a flashlight meant to be thrashed and abused, so I won' try to drown it in the toilet, smash it against a concrete sidewalk, throw it against a wall, stomp on it, sit down hard on it, or otherwise abuse it. So this portion of the web page will be more bare than this section of the web page on a page about a flashlight.

Like I said earlier, I'm not a carpenter, and I don't play one on TV or on the internet, so please read the instructional material that comes with the Laser Straight in case I missed something very important.
