English DeWALT Tool Tag Ready (Fig. A) Optional Accessory Your hammer comes with mounting holes 11 and fasteners for installing a DeWALT Tool Tag. You will need a T15 bit tip to install the tag. Only use the screws provided. The DeWALT Tool Tag is designed for tracking and locating professional power tools, equipment, and machines using the DeWALT Tool Connect™ app. For proper installation and use of the DeWALT Tool Tag refer to the DeWALT Tool Tag manual. Lock-On Button (Fig. A) Chipping mode only The lock-on button 8 offers increased comfort in extended use applications. To lock the tool on, depress the lock-on button while the tool is running. The tool will continue to run after the switch is released. To unlock and turn off the tool, depress and release the switch. NOTE: The lock-on button will not function in drilling mode. Electronic Speed and Impact Control (Fig. A) The electronic speed and impact control allows the use of smaller drill bits without the risk of bit breakage, hammerdrilling into light and brittle materials without shattering and optimal tool control for precise chiseling. To set the speed dial 9 , turn the dial to the desired level. The higher the number, the greater the speed and impact energy. Dial settings make the tool extremely flexible and adaptable for many different appli­cations. The required setting depends on the bit size and hardness of material being drilled. Overload Clutch In case of jamming of a drill bit, the drive to the drill spindle is interrupted by the overload clutch. Due to the resulting forces, always hold the tool with both hands and take a firm stance. After the overload, release and depress the trigger to re-engage drive. WARNING: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip the drill firmly to control the twisting action and avoid injury. E-Clutch® System (Fig. A) In addition to the integral (mechanical) clutch, the DeWALT anti-rotation E-Clutch® system, offers technology capable of detecting the motion of the tool. This feature senses the motion of the tool and shuts it down if necessary. The red indicator LED 10 illuminates when the E-Clutch® System is engaged. E-Clutch® and Service Indicator LEDs (Fig. A) Your rotary hammer has two LEDs 10 , indicating the E-Clutch® (ADC) function and a service indicator. Refer to the table for more information on LED functionality. LED Function Red (flashing) Red (permanently on) Yellow (permanently on) Description Lock-on/Service The red indicator LED 10 lights up if the lock-on button 8 is used in any mode except the chipping mode or if there is a fault with the tool or the brushes have completely worn out E-Clutch® E- Clutch® is engaged.
