Introduction Thank you for choosing the LP20 or LP40 Spectra Precision® Laser from the Trimble® family of precision hand-held lasers. This simple-to-use tool allows you to transfer points between the floor and ceiling and to establish 90° points for laying out wall lines and putting up wall partitions. You can also use the laser for other applications where true plumb, square, and level setups are required. Before using the laser, be sure to read this operator’s manual carefully. Included in it is information about setting up, using, and maintaining the laser. Also included in this manual are CAUTIONS and Notes. Each of these words represents a level or danger or concern. A CAUTION indicates a hazard or unsafe practice that could result in minor injury or property damage. A Note indicates important information unrelated to safety.

Battery Housing – 3 – 0002-8210 Universal Accessory Maintenance and Care You will get years of service from your laser by following the maintenance and care recommendations in this manual. However well the product is designed, mishaps do occur and the most common problems associated with these are covered in the following areas. Any damage to the laser caused by improper maintenance and care voids the warranty. Handling Precautions When transferring the laser from a very low temperature to a warmer environment or visa versa, always allow time for the laser to reach the new temperature before using. Allowing this time is especially important when transferring the laser from an extremely heated/cold vehicle to the job site. Installing/Removing the Batteries CAUTION: The batteries should be removed when storing the laser more than 30 days. 1. Release the battery door using your fingers. Open the door. 2. Install/remove the 4 AA batteries. Note: When installing the batteries, be sure to note the positive (+) and negative (–) diagrams molded on the battery housing. 3. Close the battery door and latch it shut. – 4 – – 8 – System Cleaning For maximum performance and accuracy always keep the lenses clean. When cleaning, apply very light pressure and use only a good quality glass cleaner on a soft cloth to clean the exterior of the laser and its lenses. CAUTION: A dry cloth or abrasive organic cleaner could scratch or damage these surfaces. CAUTION: Do not submerge the laser. Storage When you’re not using the laser, store it in its pouch/carrying case. CAUTION: Do not store the laser in a wet pouch/carrying case. If the pouch/carrying case gets wet, let it dry before storing the laser in it. CAUTION: The batteries should be removed when storing the laser more than 30 days. Battery Disposal Some states and local areas have regulations regarding the disposal of batteries. Be sure to dispose of discharged batteries properly. – 9 – – 10 – – 11 – – 12 – Calibration Checking Accuracy—Level Before each use, be sure to check the pocket laser for signs of 4.
