Dewalt DW085K Instruction Manual - Page 2

INTEGRATED MAGNETIC PIVOTING BRACKET (FIG. 3) The DW085 has a magnetic pivoting bracket (I) permanently attached to the unit. This bracket allows the unit to be mounted to any upright surface made of steel or iron using the magnets (J) located on the back of the pivoting bracket. Common examples of suitable surfaces include steel framing studs, steel door frames and structural steel beams. Position the laser on a stable surface. CAUTION: Do not stand underneath the laser when it is mounted with the magnetic pivoting bracket. Serious personal injury or damage to the laser may result if the laser falls. The pivoting bracket also provides floor clearance of approximately 1-3/4" (44.5 mm) which aids in the installation of steel framing track. OUT OF TILT RANGE INDICATOR (FIG. 4) The DW085 laser is designed to self-level. If the laser has been tilted so much that it cannot level itself (> 4° tilt), it will flash the laser beam. The flashing beam indicates the tilt range has been exceeded and IS 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. USING THE LASER WITH ACCESSORIES The laser is equipped with a 1/4" x 20 female thread on the bottom of the unit.

ALIGNING THE SQUARE LAYOUT - FINE AJDUST (FIG. 2) The fine adjustment knob (R) on the side of the DW085 is for lining up the horizontal beams. Place the DW085 on a flat surface and turn the knob to the right to move the beam to the right or to the left to move the beam to the left. Rotating the fine adjustment knob adjusts the entire internal mechanism, maintaining the 90° angle between the three horizontal dots. LEVELING THE LASER This tool is self-leveling. It is calibrated at the factory to find plumb as long as it is positioned on flat surface within 4° of level. As long as the tool is properly calibrated, no manual adjustments must be made. MAINTENANCE To maintain the accuracy of your work, have the laser checked often to make sure it is properly calibrated. See Field Calibration Check. Calibration checks and other maintenance repairs may be performed by DEWALT service centers. When not in use, store the laser in the kit box provided. Do not store your laser at temperatures below -5 ˚F (-20 ˚C) or above 140 ˚F (60 ˚C). Do not store your laser in the kit box if the laser is wet. The laser should be dried first with a soft dry cloth. Cleaning 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. Field Calibration Check CHECKING ACCURACY - PLUMB (FIG. 5-6) Checking the plumb calibration of the laser can be most accurately done when there is a substantial amount of vertical height available, ideally 25' (7.5 m), with one person on the floor positioning the laser and another person near a ceiling to mark the dot created by the beam on the ceiling (Fig. 5). 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. Start by marking a point on the floor. 2. Place the laser so that the down beam is centered on the point marked on the floor. 3. Allow time for the laser to settle to plumb and mark the center of the beam created by the up beam. 4. Turn the laser 180° as shown (Fig. 6), making sure that the down beam is still centered on the point previously marked on the floor. 5. Allow time for the laser to settle to plumb and mark the center of the dot created by the up beam. If the measurement between the two marks is greater than shown below, the laser is no longer in calibration. Ceiling Height Measurement Between Marks 25' (7.5 m) 0.18" (4.5 mm) 50' (15 m) 0.35" (9.0 mm) 12. Measure the distance between points K and Q (Fig. 11D). If the measurement is greater than the values indicated in the chart below, the laser must be serviced at an authorized service center. Distance Between Marks (K to M) Measurement Between Marks (K to P, or K to Q) 25' (7.5 m) 1/8" (3 mm) 50' (15 m) 1/4" (6 mm) 75' (23 m) 3/8" (9 mm) Troubleshooting THE LASER DOES NOT TURN ON • Make sure batteries are installed according to (+), (-) markings on battery door. • Make sure the batteries 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 batteries to reduce the chance of battery leakage. • If the laser has been stored in extremely hot temperatures, allow it to cool. THE LASER BEAMS FLASH (FIG. 4) The DW085 laser level has been designed to self-level up to 4° in all directions when positioned as shown in Figure 4. If the laser is tilted so much that internal mechanism cannot plumb itself, it will flash the laser-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 DW085 is a precision instrument. Therefore, if it is not positioned on a stable (and motionless) surface, the tool will continue to try to find plumb. If the beam will not stop moving, try placing the tool on a more stable surface. Also, try to make sure that the surface is relatively flat, so that the laser is stable. Service and Repairs NOTE: Disassembling the laser level will void all warranties on the product.

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. Place unit 2"-3" (5-8 cm) from first wall, facing the wall (Fig. 7). 2. Mark the beam position on the first wall. 3. Turn the unit 180˚, and mark the beam position on the second wall (Fig. 8). 4. Place the unit 2"-3" (5-8 cm) from the second wall, facing the wall (Fig. 9). 5. Adjust the height of the unit until the beam hits the mark from step 3. 6. Turn the unit 180˚, and aim the beam near the mark on the first wall from step 2 (Fig. 10). 7. Measure the vertical distance between the beam and the mark. 8. If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center. Repeat steps 1 through 8 to check the front beam, left beam, and right beam. Distance Between Walls Measurement Between Marks 25' (7.5 m) 1/8" (3 mm) 50' (15 m) 1/4" (6 mm) 75' (23 m) 3/8" (9 mm) 25' (7.5 m) FIG. 7 FIG. 8 FIG. 9 FIG. 10 FIG. 11A K FIG. 11B K CHECKING LEVEL TO SQUARE BEAM 90° ACCURACY (FIG. 11A-D) Refer to Figure 11 for the location of the DW085 at each step and for the location of the marks made at each step. All marks can be made on the floor by placing a target in front of the level or square beam and transferring the location to the floor. 1. Find a room at least 35' (10 m) long. Mark a point (K) on the floor at one end of the room (Fig. 11A). 2. Set up the laser so that its down beam is over point K. Make sure the front level beam points toward the far end of the room (Fig. 11A). 3. Mark a point (L) on the floor at the center of the room using a target to transfer the front level beam location to the floor (Fig. 11A). 4. Mark a point (M) on the far wall or transfer the front level beam location to the floor (Fig. 11A). 5. Move the DW085 to point L and align the front level beam to point M again (Fig. 11B). 6. Mark the location of two square beams as N and O on the floor. NOTE: To ensure accuracy, the distances form K to L, L to M, L to N, and L to O should be equal. 7. Turn the DW085 90° so the front level beam aligns to point N (Fig. 11C). 8. Mark the location of a first square beam (P) on the floor as close as possible to point K (Fig. 11C). 9. Measure the distance between points K and P (Fig. 11C). If the measurement is greater than the values indicated in the chart below, the laser must be serviced at an authorized service center. 10.Next, turn the DW085 90° so that the front level beam aligns to point O (Fig. 11D). 11. Mark the location of a second square beam (Q) on the floor as close as possible to point K (Fig. 11D). L M FIG. 11C PK 1 L N N L O 1 2 M FIG. 11D KQ O N 2 L O M M
