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 dan-
gerous 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

• 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 unin-
tentionally 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 con-
struction activities contains chemicals known to the State of California to cause cancer, birth
defects, or other reproductive 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.
WARNING: Use of this tool can generate and/or disburse dust, which may cause serious
and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory pro-
tection appropriate for the dust exposure. Direct particles away from face and body.
• The label on your tool may include the following symbols.
V ............................volts
mW ........................milliwatts
................laser warning symbol
nm ..........................wavelength in nanometers
II..............................Class II Laser
IIIa ..........................Class IIIa Laser
WARNING LABELS
For your convenience and safety, the following label is on your laser.
CAUTION: LASER RADIATION - DO NOT STARE INTO THE LASER BEAM.
CLASS II LASER PRODUCT.
CAUTION: CLASS 2 LASER RADIATION WHEN OPEN DO NOT STARE INTO
THE BEAM.

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 power tools 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.
• 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 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.
• 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.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use tool while tired or under the influence of drugs, alcohol, or
medication. A moment of inattention while operating power tools may result in serious
personal injury.
• Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your
hair, clothing, and gloves away from moving parts. Loose clothing, jewelry, or long hair
can be caught in moving parts. Air vents often cover moving parts and should also be
avoided.
• Do not overreach. Keep proper footing and balance at all times. Proper footing and balance
enables better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes,
hard hat, or hearing protection must be used for appropriate conditions.
TOOL USE AND CARE
• Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled
with the switch is dangerous and must be repaired.
• Store idle tools out of reach of children and other untrained persons. Tools 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 tool, may become hazardous when used on
another tool.
SERVICE
• Tool service must be performed only by qualified repair personnel. Service or mainte-
nance performed by unqualified personnel could result in a risk of injury.
• When servicing a tool, use only identical replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk of electric shock or injury.

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 batteries 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 DW086 and DW087 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).
