Safety Instructions for Lasers
WARNING! Read and understand all instructions. Failure to follow all instructions
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
procedures 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
flammable liquids, gases, or dust. Power tools 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 maintenance per-
formed by unqualified personnel may result in injury. To locate your nearest D
1-800-4-DEWALT (1-800-433-9258) or go to http://www.dewalt.com on the Internet.
• Do not use optical tools such as a telescope or transit to view the laser beam. Serious eye injury
could result.
• Do not place the laser in a position which may cause anyone to intentionally or unintentionally
stare into the laser beam. Serious eye injury could result.
• 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.
• Position the laser securely on a level surface. Damage to the laser or serious injury could result if the
laser falls.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activi-
ties contains chemi cals known to the State of California to cause cancer, birth defects, or other reproduc tive
harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such
as those dust masks that are specially designed to
filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and
other construction activities. Wear protective clothing and wash exposed areas with soap and
water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful
chemicals.
• The label on your tool may include the following symbols.

General Safety Rules For Battery Operated Tools
WARNING! Read and understand all instructions. Failure to follow all instructions
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 laser tools in explosive atmospheres, such as in the presence of flammable liquids,
gases, or dust.
• Keep bystanders, children, and visitors away while operating a laser 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 1.5V AA size batteries.
To install batteries:
1. Lift up the battery compartment cover (A) as shown in Figure 1.
2. Insert three fresh AA batteries in the compartment, placing the batteries according to (+) and (–) on the
inside of the battery door.
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.
• A lways insert batteries correctly with regard to polarity (+ and –), marked on the battery and the equip-
ment.
• Do not short battery terminals.
• Do not charge batteries.
• D o 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.
PERSONAL SAFETY

Operating Tips
• Use only new, high-quality, name brand batteries for best results.
• Ensure batteries are in good working condition. If the low battery red indicator light is flashing, the bat-
teries need replacement.
• 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 beam 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 still calibrated. See Field Calibration Check.
LOW BATTERY INDICATION
The DW087 and DW088 lasers are equipped with a red indicator light (B), as shown in Figure 2. The red indicator
lights are located to the left of the ON/OFF buttons (C, D).
A flashing red indicator light indicates that the batteries are low and need to be replaced. The laser may continue
to operate for a short time while the batteries continue to drain, but the beam(s) will quickly dim. After fresh
batteries are installed and the laser is turned on again, the laser beam(s) will return to full brightness and the
red indicator light will stay off. (A flashing laser beam is not caused by low batteries; see Out of Tilt Range
Indicator.)

OPERATION

To Turn the Lasers On and Off (Fig. 2)
With the laser off, place it on a flat surface. This model has two ON/OFF buttons, one for a horizontal laser line (C)
and one for a vertical laser line (D). Each laser line is powered on by pressing its ON/OFF button. The laser lines
can be powered one at a time or at the same time. Pressing the ON/OFF buttons again turns the laser lines off.
Using the Lasers
The beams are level or plumb as long as the calibration has been checked (see Field Calibration Check) and
the laser beam is not flashing (see Out of Tilt Range Indicator).
