hancement glasses are NOT intended to protect your eyes in any way.  
TOOL USE AND CARE  
1.  
2.  
Do not force the tool. Use the correct tool for your application. The correct  
tool will do the job better and safer at the rate for which it is designed.  
Do not use the tool if the Power Switch does not turn it on or off. Any tool  
that cannot be controlled with the Power Switch is dangerous and must be re-  
placed.  
3.  
Remove the Batteries from the tool before making any adjustments, chang-  
ing accessories, or storing the tool. Such preventive safety measures reduce  
the risk of starting the tool accidentally.  
4.  
5.  
Store idle tools out of reach of children and other untrained persons. Tools  
are dangerous in the hands of untrained users.  
Maintain tools with care. Keep tools clean and dry. Properly maintained  
tools are less likely to malfunction and are easier to control. Do not use a dam-  
aged tool. Tag damaged tools “Do not use” until repaired.  
6.  
7.  
Check for misalignment or binding of moving parts, breakage of parts, and  
any other condition that may affect the tool’s operation. If damaged, have  
the tool serviced before using. Many accidents are caused by poorly main-  
tained tools.  
Use only accessories that are recommended by the manufacturer for your  
model. Accessories that may be suitable for one tool may become hazardous  
when used on another tool.  
SERVICE  
1.  
2.  
Tool service must be performed only by qualified repair personnel. Service  
or maintenance performed by unqualified personnel could result in a risk of injury.  
When servicing a tool, use only identical replacement parts. Follow  
instructions in the “Inspection, Maintenance, And Cleaning” section of this  
manual. Use of unauthorized parts or failure to follow maintenance instructions  
may create a risk of electric shock or injury.

SPECIFIC SAFETY RULES  
1.  
WARNING! Laser light can harm the eye. Do not look directly into this  
Laser Level, or the reflection of the light. Do not allow any other person or animal  
to be exposed to the direct or reflected laser beam. If necessary, wear protective  
laser goggles (not included) appropriate for this laser type to protect yourself and  
others from harmful laser beams.  
2.  
3.  
Make sure the laser beam is aimed at a sturdy object without reflective  
surfaces. Reflective surfaces are not suitable for laser applications, as the reflec-  
tive surface may direct the laser beam back at the operator, causing potential eye  
damage.  
Do not attempt to alter the laser light or replace it with a different type. Doing  
so may result in hazardous radiation exposure. Only qualified and trained em-  
ployees must be assigned to install, adjust, and operate laser equipment.  
4.  
5.  
6.  
Never leave the Laser Level unattended when it is turned on. Make sure to  
turn off the tool before leaving the work area.  
Do not use the Laser Level if it has been dropped, damaged, or immersed in  
liquid.  
This Laser Level features a variable rotation speed of 0 to 600 RPM. Higher  
rotation speeds allow the operator to see the laser beam at greater distances  
outdoors. However, higher rotation speeds make the laser beam less detectable  
when the Laser Level is used indoors. Typically, the slower the rotation speed the  
brighter the laser beam appears. The exact speed at which that happens de-  
pends on the individual and will require dialing the rotation speed to best match  
your own eyes.  
7.  
Take care not to accidentally bump or move the Laser Level and itsTripod  
after they have been set up and leveled. If the Laser Level is accidentally  
bumped or moved you must re-level the unit and its Tripod using the Level Vials.  
Accuracy when using the Level Vials is crucial. For example, when you are  
aligning the bubble with the scribe on the Level Vial and you are “off” by just the  
thickness of the scribed line, then when you are measuring an object a hundred  
feet away that small difference will equal about three inches.  
8.  
9.  
Maintain labels and nameplates on the Laser Level. These carry important  
information. If unreadable or missing, contact Harbor Freight Tools for a replace-  
ment.  
Always turn off the Laser Level and remove its Batteries before changing

accessories, performing inspection, maintenance, cleaning procedures, or  
storing the tool.  
10.  
Battery precautions: Never burn Batteries, as they can explode in a fire. Con-  
tact local solid waste authorities for instructions on correct disposal or recycling of  
the Batteries.  
11.  
12.  
Industrial applications must follow OSHA requirements.  
Use the right tool or attachment for the right job. Do not attempt to force a  
small tool or attachment to do the work of a larger industrial tool or attachment.  
There are certain applications for which this product was designed. It will do the  
job better and more safely at the rate for which it was intended. Do not modify  
this product, and do not use this product for a purpose for which it was not in-  
tended.  
13.  
WARNING! The warnings, precautions, and instructions discussed in this  
manual cannot cover all possible conditions and situations that may occur. The  
operator must understand that common sense and caution are factors, which  
cannot be built into this product, but must be supplied by the operator.

If using the Laser Level with the Tripod (3), thread the Tripod Stud located on the  
Tripod Neck into the bottom of the Laser Level. The Tripod swivels 360 degree.  
Position the Tripod on a flat, level, dry ground surface. Extend the Legs of the  
Tripod and lock the Legs in place. Level the Tripod Neck (4), using the Level Vial  
(4) located on the Tripod Head. Then, lock the Tripod Neck in position with the  
Thumb Screw (6). (See Figure B.)

The Laser Level may also be installed on a wall surface without the Tripod (3).  
To do so, use the Wall Bracket (7) to secure the Laser Level to the wall. Use the  
wall bracket as a template. Mark drill holes and always check before drilling to  
make sure there are no hidden electrical wires or cables in the drilling path.  
Secure the Laser Level to the wall surface using screws and plastic anchors (not  
included). (See Figure A.)  
Level the Laser, using a Leveling Knob (8) located on each side of the Laser and  
the two Level Vials (9) located at the top of the Laser. (See Figure C.)

OPERATING INSTRUCTIONS  
1.  
When the Laser Level is properly positioned, turn on the Laser by rotating the  
Rotation Speed Control (10), clockwise. Then, recheck the Level Vials (4, 9) to  
make sure the Laser Level has not been bumped or moved.  
(See Figures B and C.)  
2.  
3.  
The rotation speed can be set by adjusting the Rotation Speed Control (10) knob.  
Turn the Control clockwise to make the beam rotate faster.  
Turn the Control counterclockwise to slow the beam down.  
Mark the desired measurement. Then, turn off the Laser Level by rotating the  
Rotation Speed Control (10), counterclockwise all the way. (See Figure C.)  
Using the Laser LevelTo Equalize Height Of Distant Objects:  
For example: If you wish to install cement footings for a storage shed, first deter-  
mine the desired height of any one of the footings. Align the laser beam with the  
top surface of the reference footing, and check to make sure the Vial Levels (4, 9)  
are level with the ground. 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, i.e., to align pictures on a  
wall.  
UsingThe Laser LevelTo Install Horizontal OrVertical Objects:  
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 check to make sure the Vial  
Levels (4, 9) are level with the floor. Shine the laser beam on the adjoining wall,  
and have an assistant mark that location. Then, 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 objects.  
UsingThe Laser 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 (3). Check to make sure the Vial Levels (4, 9) are  
level with the floor. Measure the vertical drop from the Laser Lens to the floor  
surface. Shine the laser beam on a ruler held vertical at the other end of the floor.  
The difference in these measurements is the amount of slope in the floor. This  
technique can also be used to design slope, such as when constructing an out-  
door surface which will require a runoff slope.
