Safety Instructions for Lasers
WARNING! Read and understand all instructions. Failure to follow all instruc-
tions listed below may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WARNING! Laser Radiation Exposure. Do not disassemble or modify the laser level.
There are no user serviceable parts inside. Serious eye injury could result.
WARNING: Hazardous Radiation. Use of controls or adjustments or performance of proce-
dures other than those specified herein may result in hazardous radiation exposure.
• Do not operate the laser in explosive atmospheres, such as in the presence of flam-
mable liquids, gases, or dust. Lasers create sparks which may ignite the dust or fumes.
• Use the laser only with the specifically designated batteries. Use of any other batteries
may create a risk of fire.
• Store idle laser out of reach of children and other untrained persons. Lasers are
dangerous in the hands of untrained users.
• Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one laser, may create a risk of injury when used on
another laser.
• Tool service must be performed only by qualified repair personnel. Service or mainte-
nance performed by unqualified personnel may result in injury. To locate your nearest

• Turn the laser off when it is not in use. Leaving the laser on increases the risk of staring
into the laser beam.
• Do not disassemble the laser tool. There are no user serviceable parts inside.
• Do not modify the laser in any way. Modifying the tool may result in Hazardous Laser
Radiation Exposure.
• Do not operate the laser around children or allow children to operate the laser. Serious
eye injury may result.
• Do not remove or deface warning labels. Removing labels increases the risk of exposure
to radiation.

General Safety Rules For Battery Operated Tools
WARNING! Read and understand all instructions. Failure to follow all instruc-
tions listed below may result in electric shock, fire and/or serious personal injury.
WORK AREA
• Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flam-
mable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep bystanders, children, and visitors away while operating a power tool. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
• Use battery operated tool only with the specifically designed batteries. Use of any other
batteries may create a risk of fire.
Battery
This tool is powered by three AA size batteries.
To install batteries:
1. Before installing batteries, ensure that the ON/OFF button is in the OFF position (button fully
extended to prevent beam from coming on while inserting batteries).
2. Refer to the label on the laser to open battery compartment.
3. Insert three fresh AA batteries in the compartment, placing the battery polarity (+ and –)
according to the label on the battery compartment.
WARNING: Batteries can explode, or leak, and can cause injury or fire. To reduce this risk:
• Carefully follow all instructions and warnings on the battery label and package.
• Always insert batteries correctly with regard to polarity (+ and –), marked on the battery
and the equipment.
• Do not short battery terminals.
• Do not charge batteries.
• Do not mix old and new batteries. Replace all of them at the same time with new batteries
of the same brand and type.
• Remove dead batteries immediately and dispose of per local codes.
• Do not dispose of batteries in fire.
• Keep batteries out of reach of children.
• Remove batteries if the device will not be used for several months.

Operating Tips
or go to
• Use only new, high-quality, name brand batteries for best results.
• Ensure batteries are in good working condition.
• To extend battery life, turn laser off when not working with or marking the beam.
• To ensure the accuracy of your work, check to make sure your laser is calibrated often. (See
Field Calibration Check.)
• Before attempting to use the laser, make sure it is positioned securely, on a smooth, flat
surface.
• Always mark the center of the dot or pattern created by the laser.
• Extreme temperature changes may cause movement of internal parts that can affect
accuracy. Check your accuracy often while working. (See Field Calibration Check.)
• If the laser has been dropped, check to make sure your laser is calibrated. (See Field
Calibration Check.)
OPERATION
To Turn the Laser On and Off
1. With the laser off, place it on a flat surface or leveling base (included). Press the ON/OFF
button to power the laser ON. The laser will turn on and project three beams; one up (A) and
two square, level beams (B, C) (Fig. 1).
2. Press the ON/OFF button again. The laser will then turn off and no laser beams will be
projected.
Using the Laser
The beams are level or plumb as long as the calibration has been checked. (See Field
Calibration Check.) The laser can be used to level, plumb and square points using any
combination of the three beams. (See Leveling the Laser.)
NOTE: The laser has magnets which can be used to help position the tool against steel
surfaces. Always make sure the tool is positioned securely and on a smooth surface.
