2. Snap the steel ring (K) over the collar (L) behind the tool holder (M). Squeeze both ends of the steel ring together. Mount the bushing (N) and insert the pin (O). 3. Slide the side handle clamp (J) over the bushing and screw on the clamp knob (H)–do not tighten. 4. Screw the side handle (C) into the clamp knob (H) and tighten. 5. Rotate the side handle mounting assembly to the desired position. For hammerdrilling horizontally with a heavy drill bit, place the side handle assembly at an angle of approximately 20° to the tool for optimum control. 6. Lock the side handle mounting assembly in place by tightening the clamp knob (H). TO MOUNT IN REAR POSITION (FIG. 3) 1. Unscrew the side handle (C) and remove it from the side handle mounting assembly. Leave the side handle mounting assembly in the front position. 2. Screw the side handle directly into one of the rear side handle positions (I) on either side of the tool. Active Vibration Control (Fig. 1) D25602, D25651, D25831, D25851 For best vibration control, hold the tool with one hand on the main handle (D) and the other hand on the side handle (C). Apply just enough pressure so the damping device on the main handle is approximately mid stroke. The hammer only needs enough pressure to engage the active vibration control. Applying too much pressure will not make the tool drill or chip faster and active vibration control will not engage. Inserting and Removing Spline Drive Accessories (Fig. 4) D25553, D25651, D25851 WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before making any adjustments or removing/installing attachments or accessories. 1. Insert the bit shank into the tool holder (M) as far as it will go. The groove on the chisel shank (Q) must be aligned with the symbol (R) on the toolholder. If inserted correctly, the locking sleeve (P) moves back to the end position and shows a closed lock symbol. 2. Pull on the bit to be sure that it is properly locked. 3. If the chisel groove is not aligned with the symbol, or is not inserted to the complete depth the lock symbol remains open. To remove the bit, pull back the locking sleeve and pull the bit out. Inserting and Removing SDS Max® Accessories D25501, D25602, D25831 WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before making any adjustments or removing/installing attachments or accessories. 1. Pull back the locking sleeve (P) and insert the bit shank. The bit shank must be clean. 2. Turn the bit slightly until the sleeve snaps back into position. 3. Ensure the bit is properly engaged. NOTE: The bit needs to move several centimeters in and out of the tool holder (M) when properly engaged. 4. To remove the bit, pull back the locking sleeve and pull the bit out. Complete Torque Control (Fig. 5) D25602, D25651 NOTICE: Always turn the tool off before changing torque control settings or damage to tool may result. The Complete Torque Control (CTC) feature of this tool is designed to provide additional control with a two-stage clutch mechanism. Clutch Setting 1 (S) is designed for most hammerdrilling applications and is designed to easily clutch out when the drill bit encounters re-bar or other foreign substances. Clutch Setting 2 (T) is designed for higher torque applications such as core-bits and deep hole hammerdrilling and is designed to clutch out at a higher torque threshold. Move the torque control lever (U) to setting 1 or 2 as needed for application. 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. 5) D25602, D25651, D25831, D25851 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 (G) 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 appli cations. 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 D25501, D25553, D25602, D25651 uses 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 D25831 and D25851 use 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 imp...
