The laser beam center is positioned 1/2 inch from the bottom of the level. This means that a half inch needs to be
subtracted from the center spot of the laser dot to reference the actual bottom of the level.
Mark the bull’s eye of the circular "target" and subtract 1/2 inch. This second mark is level with the bottom of the
L100M MX Laser Precision Level™ within 1/8 inch out to 100 feet or any distance in between!
Helpful hints:
1. To find the laser dot on long shots, follow the laser beam out to the marking spot by sticking a piece of paper or
any target in front of the beam and tracing the beam path to the marking spot. This works great in bright sunlight
conditions. Also, even though the laser beam is low powered, avoid looking directly into the laser beam. The laser
beam is quite bright.
2. To aim the laser in the general direction of the shot, sight down the top of the laser by looking lengthwise down
the top of the level at the target spot.
Battery Replacement:
Unscrew the battery compartment end cap and remove the batteries. Replace with 2 Panasonic CR 123A Lithium
Photo Batteries or equivalent.
Remember: The negative ends (the flat end of the battery) goes in first. The positive ends with the button end
sticking up go toward the brass end cap.
Maintenance:
The L100M MX Laser Precision Level™ is designed to be weather resistant and construction tough, but like any
precision instrument, general care should be taken to avoid abuse.
1. The precision glass level vial and plumb vials are protected and shock mounted. Avoid direct contact with the
level vials.
2. The front optic window is coated with a high performance film. Clean with a lint free cloth or swab using a
premium glass cleaner solution.
3. Clean the outside of the level with a damp cloth.
Calibration: The L100M MX Laser Precision Level™ uses wedge prisms for beam steering and should not
require any adjustments for the life of the unit. However should adjustments or repairs be required, contact Laser
