• 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.

PERSONAL SAFETY
• Stay alert, watch what you are doing and use common sense when operating a laser 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.
• 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 may be
required 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 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 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.
