• Do not stare directly at the laser beam.
• Do not project the laser beam directly into the eyes of others.
• 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.
• Keep the laser tool out of the reach of children and other untrained persons.
• Do not attempt to view the laser beam through optical tools such as telescopes as
serious eye injury may result.
• Always turn the laser tool off when not in use or left unattended for a period of time.
• Remove the batteries when storing the tool for an extended time (more than 3 months)
to avoid damage to the tool should the batteries deteriorate.

IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Battery Installation
Unscrew the cover on the back top of the unit and insert four (4) AA
batteries (included). Follow polarity on housing.
Note: Used/discharged batteries are hazardous waste and must be
disposed of properly.
Tripod Set-up
Open up the tripod and position it firmly on a surface that is even
and as near level as possible. For uneven surfaces and inclines,
compensate by adjusting the telescoping legs of the tripod. Tightly
screw the unit and tripod together.
The rotary laser can be used either with the tripod or independently.
Leveling the Laser
Bring the unit into a level position by means of the horizontal “X” and
“Y” adjusting screws (top mounted vials for horizontal application)
and one (1) vertical “Z” adjusting screw (one side mounted vial for
vertical application).
To obtain accurate measures, use the leveling screws found on the
mounting base and ensure that the bubble in each vial is perfectly
centered.

7. Using the Product
To turn on, rotate the on/off and variable speed switch in the
direction indicated by the arrow. Use this on/off and variable speed
control knob to create a single laser point or an intermittent line or
a continuous line. The slower the rotation, the more visible the
beam will be. If used with an optional detector, use fastest rotation
speed.
Note: Due to the 360° rotating feature of the laser beam, extra care
must be taken to avoid direct contact with the eyes.

8. Self-Check & Fine Calibration
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Checking for Accuracy:
1. Start by placing the laser 1’ away from a wall (near wall), and
at least 20’ from a wall (far wall).
2. Align the laser so that one axis (vial) points to both walls.
3. Turn the laser on and adjust the thumbscrews until the unit is
level in both the X and Y axis.
4. Make a mark where the laser hits the near wall (wall #1), and
then the same for the far wall (wall #2).
5. Next, move the laser to 1’ next to the far wall, and ensure it is
in the same axis.
6. Level the laser, and then adjust the height so that the laser is
level and hits the mark you made on the far wall (wall #2).
You may need to re-level to achieve this.

7. Then walk over to the original near wall (wall #1) and measure
the difference between the original mark and the laser line. If
the value is more than 1/8” at 30’, then calibration is required.
8. Ensure accuracy is verified for both the X and Y axis.
Note: X and Y axis are determined by the end user, either vial can be
considered X/Y.
Adjusting Accuracy:
1. Measure the difference between the original near wall mark
(wall #1) and where the laser is hitting the near wall.
2. Walk back to the far wall (wall #2) and adjust the laser so that
it is halfway between the two near wall marks (pencil mark
and laser mark).
3. Next, remove the screw cap for the vial for the axis you are
working with, and using a 2.5mm hex tool, adjust the vial so
that it appears level.
