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.
