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. 6 Operation To Turn the Lasers On and Off (See Figure 2 , 5 ) With the laser off, place it on a flat surface. This model has a pendulum locking switch B and a keypad C to activate the laser beams with two ON/OFF buttons; one for a horizontal laser line D and one for a vertical laser line E . Each laser line is powered on by moving the pendulum lock switch B to the UNLOCKED/ON position and pressing the required ON/OFF button on the keypad. The laser lines can be powered one at a time or at the same time. Pressing the ON/OFF buttons again turns the laser lines off. The pendulum locking switch disables the lasers as well as locking the pendulum, and should always be placed in the LOCKED/OFF position when the laser is not in use. If the pendulum lock switch is not placed in the lock position all 4 LED's will continuously flash on the Battery Meter. Using the Lasers Out of LEVEL Range Indicator The lasers are designed to self-level. If the laser has been tilted so much that it cannot self-level ( > 4° ), the laser beam will flash. There are two flashing sequences associated with the out of level condition: (i) between 4° and 10° the beams flash with a constant blink cycle; (ii) at angles greater than 10° the beams flash with a three blink cycle. When the beams flash the laser 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. The laser ceiling mount J (if included) offers more mounting options for the laser. The ceiling mount has a clamp at one end K which can be fixed to a wall angle for acoustic ceiling installation. At each end of the ceiling mount is a screw hole M , allowing the ceiling mount to be attached to any surface with a nail or screw. Once the ceiling mount is secured, its steel plate provides a surface to which the magnetic pivot bracket G can be attached. The position of the laser can then be fine-tuned by sliding the magnetic pivot bracket up or down on the wall mount. Using the Lasers with Accessories The lasers are equipped with 1/4 - 20 and 5/8 -11 female threads on the bottom of the unit. This thread is to accommodate current or future DeWALT accessories. Only use DeWALT accessories specified for use with this product. Follow the directions included with the accessory. CAUTION: The use of any other accessory not recommended for use with this tool could be hazardous. If you need any assistance in locating any accessory, please contact DeWALT Industrial Tool Co., 701 East Joppa Road, Towson, MD 21286 or call 1-800-4-DeWALT (1-800-433-9258) Leveling the Lasers As long as the lasers are properly calibrated, the lasers are self-leveling. Each laser is calibrated at the factory to find level as long as it is positioned on a flat surface within ± 4° of level. No manual adjustments must be made. Using the Pivot Bracket (See figure 3 ) The lasers have a magnetic pivot bracket G permanently attached to the units. This bracket allows the unit to be mounted to any upright surface made of steel or iron. Common examples of suitable surfaces include steel framing studs, steel door frames and structural steel beams. The bracket also has a keyhole slot H allowing the unit to be hung from a nail or screw on any kind of surface. Position the laser and/or wall mount on a stable surface. Serious personal injury or damage to the laser may result if the laser falls. Maintenance • To maintain the accuracy of your work, check the laser 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 prior to storage. Using the Laser with the CEILING Mount (See Figure 5 ) 7
