GL100 MX LASER PRECISION LEVEL
with Green Laser Technology™
Operating instructions:
The model GL100 MX Laser Precision Level is a hand carried precision level with a built in GREEN 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!

hazardous radiation exposure.
The level and plumb vials built into the GL100 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 Green.) Dark colors soak
up the light so the laser dot will be less bright. The GL100 MX Laser Precision Level is bright enough to be seen in direct
