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.
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 GL100
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 Duracell, MN1500 “AA” Alkaline
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 GL100 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 vials are protected and shock mounted. Avoid direct contact with 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 GL100 MX Laser Precision Level is factory calibrated and should not require any adjustments for the
life of the unit. However should adjustments or repairs be required, contact Laser Tools Co., Inc. directly.
Accessories:
The GL100 MX Laser Precision Level can be mounted to standard
camera tripods for stand alone operation. However, to speed up the fine
tuning of the level vial, the AP100A Leveling Adapter Plate or the
AP1000 Transit Adapter Plate is recommended. Both the AP100A and
AP1000 are designed with a 3 or 4 position adjustment system that
quickly and accurately centers the bubble within the level. This means
that the GL100 MX Laser Precision Level can be leveled and turned in a
360 degree circle to shoot in any direction without wasting time to
readjust the tripod for level. The AP100A and the AP1000 can be used
on any flat surface.
