•  Store an idle laser out of reach of children and other 
untrained persons. Lasers are dangerous in the hands of 
untrained users.
•  Tool service MUST be performed by qualied repair 
personnel. Service or maintenance performed by unqualied 
personnel may result in injury. To locate your nearest D
EWALT 
service center go to http://www.DEWALT.com.
•  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.
•  Do not position the laser near a reective surface which 
may reect the laser beam toward anyone’s eyes. 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 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. If labels are 
removed, the user or others may inadvertently expose 
themselves to radiation.
•  Position the laser securely on a level surface. If the laser 
falls, damage to the laser or serious injury could result.
Personal Safety
•  Stay alert, watch what you are doing, and use common sense 
when operating the laser. Do not use the laser when you are 
tired or under the inuence of drugs, alcohol, or medication. 
A moment of inattention while operating the laser may result 
in serious personal injury.
•  Use personal protective equipment. Always wear eye 
protection. Depending on the work conditions, wearing 
protective equipment such as a dust mask, non-skid safety 
shoes, hard hat, and hearing protection will reduce personal 
injury.
Tool Use and Care
•  Do not use the laser if the Power/Transport Lock switch 
does not turn the laser on or off. Any tool that cannot be 
controlled with the switch is dangerous and must be repaired.
•  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.
