18. Be Eye Aware. Laser light can potentially harm the eye. WARNING: Do not  
look directly into this laser, or the reflection of the light. Do not allow any other  
person or animal to be exposed to the direct or reflected laser beam.  
Warning: The warnings, cautions, and instructions discussed in  
this instruction manual cannot cover all possible conditions and  
situations that may occur. It must be understood by the operator  
that common sense and caution are factors which cannot be built  
into this product, but must be supplied by the operator.  
Unpacking  
When unpacking, check to make sure the following parts are included.  
(1) Mini laser level  
(1) Tripod  
(3) 1.5V AG13 button cell batteries  
(1) Instruction booklet  
If any parts are missing or broken, please call Harbor Freight Tools at the number  
on the cover of this manual.  
Assembly  
1. To install batteries, unscrew the On/Off switch assembly, and insert three (3)  
1.5v batteries (included). Be sure to install the batteries matching the polarity  
marked in the battery compartment.  
2. This level may be used with or without the tripod. To install or remove the  
tripod, thread the tripod stud located on the tripod head into the bottom of  
the level. The tripod swivels 360 degrees, and may be tilted at up to 90  
degrees vertical. If using the tripod, adjust it as desired, and lock the level  
into place using the thumb screw located on the tripod head.  
3. The tripod legs may be extended and locked into place to provide greater  
working height or to compensate for an uneven surface.

Operation  
WARNING: Never allow the laser light or its reflection to shine  
directly into the eyes of any person or animal.  
Severe eye injury may result.  
1.  
2.  
Determine the intended use of the level, and optionally install the tripod,  
if it will be needed.  
Align the laser level as required, observing the vertical, horizontal or 45  
degree spirit levels. These will indicate the relative position of the laser  
level to actual level.  
3.  
4.  
When the laser level is correctly positioned, turn on the laser by depress-  
ing the On/Off switch at the end of the level. Recheck the spirit levels to  
be sure the laser level has not been moved.  
Mark the desired measurement, then turn the laser off by depressing the  
On/Off switch.  
Using the level to equalize height of distant components: For  
example: If you wish to install cement footings for a storage shed, first determine  
the desired height of any one of the footings. Align the laser beam with the top  
surface of the reference footing, and assure that the liquid level on top of the laser  
level is at level with the ground. Now direct the laser beam toward each of the  
remaining footing locations. On reference stakes at those locations, mark the spot  
that the laser illuminates. This indicates the desired top surface of that footing.  
This technique can be used for many similar applications, for example to align  
pictures on a wall.  
Using the level to install horizontal or vertical components: For  
example: To install a chair rail on an interior wall, first mark the desired height of  
the rail. Align the laser level with that point, and assure that the liquid level  
indicates level with the floor. Shine the laser light on the adjoining wall, and have  
an assistant mark that location. Now install the chair rail in a direct line between  
the two points. This same technique can be used to install vertical or 45 degree  
angle components.  
Using the level to check slope: For example: To determine the slope  
of a floor, place the laser level at one end of the floor, using the tripod. Assure that  
the laser is level to the ground by observing the liquid level on the top. Measure  
the vertical drop from the laser lens to the floor surface. Shine the laser light on a  
ruler held vertical at the other end of the floor. The difference in these measure-  
ments is the amount of slope in the floor. This technique can also be used to  
design slope, such as when constructing an outdoor surface which will require a  
run-off slope.  
Your laser level is a versatile tool. The above suggestions are only a few  
of the many uses you will discover for this tool.
