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.
