English Electronic Speed and Impact Control (Fig. E) 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 chipping. To set the control dial, turn the dial 7 to the desired level. The higher the number, the greater the speed and impact energy. Dial settings make the tool extremely adaptable for many different applications. The required setting depends on the bit size and hardness of material being drilled. Mode Selector (Fig. A) NOTICE: Never change the mode while the unit is running. Tool must come to a complete stop before activating the mode selector button or damage to the tool may result. CAUTION: Do not change to hammerdrill mode with chisel bit in tool holder. Personal injury and damage to tool may result. The D25604 and D25652 use two operating modes. To select the required operating mode, rotate the mode selector 6 until the arrow points to the hammerdrilling or the chipping icon. The D25831 and D25851 use only the chipping mode. Rotary Hammering Mode ( ) D25604, D25652 The tool simultaneously rotates and impacts the work. This mode is appropriate for all concrete and masonry operations. Chipping Mode ( ) D25831, D25851 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 ( ) D25604, D25652, D25831, D25851 Turn the mode selector to one of the chisel bit adjustment icons to adjust the chisel to the desired position. There are multiple 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. Indicator Lights (Fig. A, E) The yellow brush wear indicator LED 10 lights up when the carbon brushes are nearly worn out indicating that the tool needs servicing within the next 8 hours of use. The red indicator LED 9 lights up if the lock-on slider 2 and/or E-Clutch® System is engaged in any mode except the chipping mode. 6 The red indicator LED 9 starts to flash if there is a fault with the tool or the brushes have completely worn out (refer to Repairs under Maintenance). INDICATOR OFF SOLID FLASHING DIAGNOSIS SOLUTION Tool is functioning normally Follow all warnings and instructions when operating tool Perform and protect With tool properly control has been supported, release activated trigger; the tool will function normally when the trigger is depressed again and the indicator light will go out Perform and protect control is malfunctioning Take the tool to an authorized DeWALT repair agent. NOTE: If the tool power is insufficient for normal hammering and if the LED does not flash repeatedly after cycling the trigger, take the tool to an authorized DeWALT repair center. OPERATION WARNING: To reduce the risk of serious personal injury, turn unit off and disconnect it from power source before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury. WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is anchored or clamped firmly. If hammerdrilling thin material, use a wood "back-up" block to prevent damage to the material. WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the side handle properly installed and securely tightened. Failure to do so may result in the side handle slipping during tool operation and subsequent loss of control. Hold tool with both hands to maximize control. WARNING: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip the drill firmly with both hands to control the twisting action and avoid injury. NOTE: Operating temperature of this tool is 19 ˚F to 104 ˚F (-7 ˚C to +40 ˚C). Using the tool outside of this temperature range will decrease the life of the tool. Proper Hand Position (Fig. F) WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position as shown. WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of a sudden reaction.
