  • Page 8: General Safety Rules

    General Safety Rules Read all instructions. Failure to follow all instructions listed below may result in hazardous radiation exposure, electric shock, fire and/or serious injury. The term “laser measure” in the warnings listed below refers to your battery-operated (cordless) laser mea- suring tool.
  • Page 9 Never aim the beam at a workpiece with a reflective surface. Bright shiny reflective sheet steel or similar reflective surfaces are not recommended for laser use. Reflective surfaces could direct the beam back towards the operator. Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
  • Page 10: Electrical Safety

    Electrical safety Batteries can explode or leak, cause injury or fire. To reduce this risk, always follow all instructions and warnings on the battery label and package. DO NOT short any battery terminals. DO NOT charge alkaline 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.
