3. How to use Laser Level

Introduction:

Congratulations! You have just purchased a time-saving precision laser tool of superior quality. The laser level is both precise and easy to use. Simply turn the laser level on and you have three, perfectly square beams for your level, plumb and square applications. Use the bubble vials to manually level your new laser level.

Turning laser level on and off:

To turn the laser level on, turn the knob on the back of the unit clockwise.

To turn the laser level off, turn the knob counter clockwise to the original position.

Leveling laser level:

The laser level has three 90° beams that can be used to level, plumb and square.

When the laser level is in the horizontal orientation the bubble in the bubble vial (A) in the middle of the unit must

be centered.

When the laser level is in the vertical orientation the bubble in the bubble vial (B) closest to the beams must be centered.

Battery Replacement:

Turn on/off switch on the back of the laser level in the counter-clockwise direction and completely unscrew the switch. This will provide you access to the battery compartment. Replace all three batteries and then return the switch to the original position.

Note: Alkaline batteries offer the longest battery life when used in this device.
