6. Operating Instructions
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Battery Installation
Open the cover on the back of the unit in
accordance with markings on the cover and insert
three AAA batteries (included in 40-0912 only).
Place cover back onto unit.
Note: Used (discharged) batteries are hazardous
waste and should be disposed of properly.
The unit must be locked/turned off before returning the laser to its
case. Locking the unit must be done when the unit is in its upright
position. It is done to hold the internal components in place to avoid
damage to the internal mechanism during transport. The
knob must be unlocked/turned on prior to each use and
locked/turned off after each use of the laser.
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.
Tripod working range from 17" to 47".
The laser can be used either with the tripod or independently.

7. Using the Product
Horizontal and Vertical Line Projection
Turning on the knob on the side of the unit will generate a simultaneous
vertical and horizontal line laser beam. To turn off, simply turn knob
counter-clockwise. If you have unlocked the knob on side of the unit
(as per previous page) then simply allow for the unit to level itself.
The unit can be manually rotated to the full 360º range.
Note: The laser level is able to compensate for slope of +/- 6º. If
the level is placed on a slope that is too great, it will not be able to
level itself accurately. The laser beam will flash if outside of its
leveling range.

8. Self-Check & Fine Calibration
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Re-calibration can be performed as described below:
1. Use a level to mark a horizontal reference line on the wall.
2. Power on the unit to compare the projected horizontal line with
its reference. Compensator has to be locked before making
calibration adjustments. If the line is tilted, remove the side
plastic screw/plug and use a 2 mm hex head wrench to cali-
brate the unit through its side calibration hole. Rotate the hex
head wrench clockwise when the horizontal line tilts to the
right. Rotate the hex head wrench counter-clockwise when the
horizontal line tilts to the left.
3. If the horizontal line is too low or too high, carefully remove the
housing by removing the four screws located at the top of the
housing. Carefully remove the housing paying close attention
to the power cord inside the unit. Locate the three screws at
the front of the unit below the glass prisms. If the line needs
to be moved down, loosen the two outer screws and tighten
the inner screw. If the line needs to be moved up, loosen the
inner screw and tighten the two outer screws. Reassemble the
housing after completing the calibration procedure.
