Clutch setting #2 (R) is designed for higher torque applications such as core-bits and deep hole drilling. NOTE: Allow the motor housing to rotate a little while changing torque. Each time the tool is plugged in, it will automatically default to clutch setting #1, the most sensitive setting. Electronic Speed and Impact Control (Fig. 4) The electronic speed and impact control allows the use of smaller drill bits without the risk of bit breakage, drilling into light and brittle materials without shattering and optimal tool control for precise chiseling. To set the control dial, turn the dial (G) 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. Mode Selector (Fig. 1) CAUTION: Never change the mode while the unit is running. CAUTION: Do not change to hammerdrill mode with chisel bit in tool holder. Personal injury and damage to tool may result. The D25701 and D25730 use two operating modes. To select the required operating mode, rotate the mode selector (F) until the arrow points to the hammerdrilling or the chipping icon. The D25890 uses only the chipping mode. HAMMERDRILLING MODE ( ) The tool simultaneously rotates and impacts the work. This mode is appropriate for all concrete and masonry operations. CHIPPING MODE ( ) The spindle lock is engaged during chipping mode so the tool impacts the work without rotating. This mode is appropriate for light chipping, chiseling and demolition applications. NOTE: In chipping mode, the hammerdrill can also be used as a lever to free a jammed drill bit. CHISEL BIT ADJUSTMENT ( ) Turn the mode selector to one of the chisel bit adjustment icons to adjust the chisel to the desired position. There are 24 possible positions to set the angle of the chisel. After finding the desired position, slightly maneuver the chisel bit back and forth to ensure the chisel is properly engaged. Power Indicator Lights (Fig. 4) The red LED light (S) indicates a serious problem and the tool should be taken to a DEWALT authorized service center for repair. The yellow LED light (T) indicates when brushes are nearly worn and the tool needs servicing. After approximately 8 hours of use, the motor will automatically shut off. The tool should be taken to a DEWALT authorized service center for routine inspection and maintenance. OPERATION NOTE: Operating temperature of this tool is 19° to 104° F (-7 to +40° C). Using the tool outside of this temperature range will decrease the life of the tool. Switch (Fig. 1) To turn the tool on, depress the trigger switch (A). To stop the tool, release the trigger switch. To lock the trigger switch on, push the lock-on slider (B) upwards while depressing the trigger switch. To deactivate the lock-on slider, depress the trigger switch once then release. The lock-on slider may only be activated in chisel mode. The machine will stop running when trying to engage the lock-on slider in drill mode. The motor will stop if the lock-on slider is activated when changing from chisel mode into drill mode. SOFT START FEATURE The soft start feature allows you to build up speed slowly, thus preventing the drill bit from walking off the intended hole position when starting. The soft start feature also reduces the immediate torque reaction transmitted to the gearing and the operator if the hammer is started with the drill bit in an existing hole. Drilling (D25701, D25730) NOTE: The D25890 has only chipping mode with no drilling capability. DRILLING WITH A SOLID BIT 1. Set the model selector to hammerdrilling mode.

Move the torque control lever to Setting 1 (Q). 3. Set the speed and impact control dial. 4. Insert the appropriate drill bit. 5. Adjust the side handle (front or rear position). 6. Mark the spot where the hole is to be drilled. 7. Place the drill bit on that mark and depress the trigger switch. 8. Apply only enough pressure to engage active vibration control (refer to Active Vibration Control). 9. To stop the tool, release the trigger switch. Always turn the tool off when work is finished and before unplugging. DRILLING WITH A CORE BIT CAUTION: Do not use a core bit for drilling wood. Personal injury and damage to tool may result. 1. Set the model selector to hammerdrilling mode. 2. Move the torque control lever to Setting 2 (R). 3. Turn the speed and impact control dial to the maximum torque position. 4. Adjust the side handle (front or rear position). 5. Assemble the cent...
