L100M MX LASER PRECISION LEVEL™ 

Operating instructions: 

The Model L100M MX Laser Precision Level™ is a hand carried precision level with a built in LASER! This 

Laser projects a beam of light from the end of the level and produces an eye visible laser dot that can be seen on 

almost any surface even in direct sunlight. The laser actually extends the level reference to over 500 FEET and is 

ten times brighter than standard red laser beams. 

Here's How It Works.... 

1. Measure level or plumb using the precision level vial or two plumb vials. They're built in and factory 

set. 

2. Turn the laser on by turning the battery cap switch. 

3. Mark the center of the laser dot and subtract 1/2 inch to reference the bottom of the level. 

IT'S THAT SIMPLE!

result in hazardous radiation exposure. 

The level and plumb vials built into the L100M MX Laser Precision Level™ are used just like standard spirit 

levels. Just center the bubble between the long index lines for a level indication. Remember, the more accurate the 

bubble is centered between the lines, the more accurate the laser beam will be for referencing level. Note: Give 

the bubble a few seconds to settle after moving the level. 

Turn the laser beam on by rotating the battery compartment end cap clockwise. To turn the beam off, 

turn the end cap counter-clockwise a quarter turn. Avoid over tightening since it isn't necessary. (CDRH: 

The battery cap On/Off is an alternate to the beam attenuator requirement.) 

The laser beam produces a bright green spot on most any reflective surface. However, the laser dot can be seen 

best when the surface is of a lighter color (i.e. wooden 2x4s, white wallboards, forms, and anything colored White 

or Red.) Dark colors soak up the light so the laser dot will be less bright. The L100 MX Laser Precision Level™ 

is bright enough to be seen in direct sunlight. The laser dot can be seen better when the sun is shaded from shining 

directly onto the laser dot. Standing in front of the sun or using a sun screen (your hand, your helper’s body, a 

piece of paper, etc.) will work.
