• Do not set up laser tool at eye level or operate the tool near a reflective surface as
the laser beam could be projected into your eyes or into the eyes of others.
• Do not place the laser tool in a manner that may cause someone to unintentionally
look into the laser beam. Serious eye injury may result.
• Do not operate the tool in explosive environments, i.e. in the presence of gases or
flammable liquids.

6. perating Instructions
Battery Installation
Remove battery door by rotating it counter-
clockwise, put in two alkaline “AAA”
batteries according to the illustrated polarity
requirements, then install the battery door by
rotating it clockwise.
Note: Used (discharged) batteries are hazardous waste and should be
disposed of properly.
7. Using the Product
Power n/ ff
1. Press power switch to project laser line or point.
2. Press power switch again to shut off laser output.
Switch Between Laser Point
and Laser Line
1. Turn the mode conversion knob to switch
between laser line and laser point. Rotating
the lens up or down converts laser from a dot
to a line, or line to a dot. Rotating the lens
counter-clockwise, while in line
mode, rotates line from horizontal to vertical.

8. Self-Check & Fine Calibration
IMP RTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Checking Vials
Start by making sure that the vials are accurate. This is done by
placing the level on a flat surface and noting the position of the vial.
Rotate the level by 180 degrees (on the same gauging edge) and
observe that the bubble is in the same position.

Calibrating Vials
To access the calibration screws remove the stickers located to the
right and left of the vial at the top of the unit. First, adjust the
calibration screws to move the bubble back to center taking out half
of the error in the vial. Rotate the level 180° on the same gauging
edge and move the bubble to center. Repeat this process until the
error is entirely removed and the bubble stays in the center. Plumb
vial, cross check vial and 45° vial cannot be calibrated.
Checking Laser
Once the vials are accurate, laser accuracy can be verified (near tar-
get, far target method). Start by placing the unit on a flat surface and
aim the laser at a stationary target. Position the unit/target at close
range and note a reference point on the target. As the unit is moved
away from the target, such that alignment of the laser to the target is
fixed, and the only variable is distance, the accuracy of the laser can
be verified/calibrated.
Calibrating Laser
There are set screws on the side and bottom of the unit that provide
calibration for the laser. One screw will need to be loosened before
the opposite screw can be tightened.
For vertical calibration, use underside screws, tightening the front
screw to adjust up and tighten the rear to adjust down.
For horizontal calibration, use two screws on either side of the unit.
Tighten the right screw to adjust right. Tighten the left screw to
adjust left.
