EN Checking Accuracy - Horizontal Beam, Pitch Direction (See figure 7 ) User Manual Checking the horizontal pitch calibration of the laser requires a single wall at least 30' (9m) long. It is important to conduct a calibration check using a distance no shorter than the distance of the applications for which the tool will be used. 1. Attach the laser to one end of a wall using its pivot bracket. Cleaning 2. Turn on the laser's horizontal beam and pivot the laser toward Exterior plastic parts may be cleaned with a damp cloth. Although these parts are solvent resistant, NEVER use solvents. Use a soft, dry cloth to remove moisture from the tool before storage. 3. the opposite end of the wall and approximately parallel to the adjacent wall. Mark the center of the beam at two locations c , d at least 30' (9m) apart. Accuracy Check and Calibration 4. Reposition the laser to the opposite end of the wall. 5. Turn on the laser's horizontal beam and pivot the laser back toward the first end of the wall and approximately parallel to the Checking Accuracy - adjacent wall.

Mark the center of the beam e directly above or below the farthest mark c . 8. Measure the distance between these two marks c , e . 1. Attach the laser to a wall using its pivot bracket. Make sure the laser is facing straight ahead. 9. If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center. 2. Turn on the laser's horizontal beam and pivot the laser approximately 45˚ so that the right-most end of the laser line is Checking Accuracy - striking the opposing wall at a distance of at least 30' (9m).

It is important to conduct a calibration check using a distance no shorter than the distance of the applications for which the tool will be used.

Turn on the laser's vertical beam and position the unit at one end of the line, facing the line. 3. Adjust the unit so its beam is aligned and centered on the line on the floor. 4. Mark the position of the laser beam on the ceiling f . Mark the center of the laser beam directly over the midpoint of the line on the floor. 5. Reposition the laser at the other end of the line on the floor. Adjust the unit once again so its beam is aligned and centered on the line on the floor. 6. Mark the position of the laser beam on the ceiling g , directly beside the first mark f . 8 7. Measure the distance between these two marks. The Battery Meter LED's Flash 8. If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center. When all 4 LED's continuously flash on the Battery Meter this indicates that the unit has not been fully powered off using the Distance Between Walls Allowable Distance Between Marks Pendulum Lock switch B . The Pendulum Lock switch should always be placed in the LOCKED/OFF position when the laser is not in use. 30' (9m) 40' (12m) 50' (15m) 1/4" (6.0mm) 5/16" (8.0mm) 13/32" (10.0mm) Service and Repairs • Note: Disassembling the laser level(s) will void all warranties on the product. Troubleshooting The Laser Does Not Turn On • Make sure AA batteries (when used) are installed correctly according to (+) and (-) on the inside of the battery door. • Make sure the batteries or rechargeable pack are in proper working condition. If in doubt, try installing new batteries. • Make sure that the battery contacts are clean and free of rust or corrosion. Be sure to keep the laser level dry and use only new, high-quality, name brand batteries to reduce the chance of battery leakage. • If the laser unit is heated above 120˚F (50˚C), the unit will not turn on. If the laser has been stored in extremely hot temperatures, allow it to cool. The laser level will not be damaged by pressing the on/off button before cooling to its proper operating temperature. To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment should be performed by authorized service centers. Service or maintenance performed by unqualified personnel may result in a risk of injury.

The Laser Beams Flash The DW088LR and DW088LG have been designed to self-level up to an average of 4° in all directions when positioned as shown in 3 . If the laser is tilted so much that internal mechanism cannot level itself, the laser beam will flash indicating that the tilt range has been exceeded. The flashing beams created by the laser are not level or plumb and should not be used for determining or marking level or plumb. Try repositioning the laser on a more level surface. The Laser Beams Will Not Stop Moving The DW088LR and DW088LG are precision instruments. Therefore, if the laser is not positioned on a stable (and motionless) surface, the laser will continue to try to find level. If the beam will not stop moving, try placing the laser on a more stable surface. Also, try to make sure that the surface is relatively flat, so that the laser is stable. 9
