Dewalt D25604K Instruction Manual - Page 9

Proper hand position requires one hand on the side handle 3 , with the other hand on the main handle 4 . Fig. F 4 3 Trigger Switch (Fig. A) D25604, D25652 In chipping mode only, lock the trigger switch on by pushing the lock-on slider 2 upward 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 chipping mode. The machine will stop running when trying to engage the lock-on slider in hammerdrilling mode. The motor will stop if the lock-on slider is activated when changing from chisel mode into hammerdrilling mode. D25831, D25851 For continuous operation, move the toggle switch 1 to the on position. To stop continuous operation, move the toggle switch to the off position. 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. Hammerdrilling with a Solid Bit (Fig. A, E) D25604, D25652 NOTE: The D25831 and D25851 have only chipping modes with no hammerdrilling capability. 1. Set the mode selector 6 to hammerdrilling mode. 2. Insert the appropriate drill bit. 3. Adjust the side handle (front or rear position) 3 . 4. Mark the spot where the hole is to be drilled. 5. Place the drill bit on that mark and depress the trigger switch 1 . 6. Apply only enough pressure to engage active vibration control (refer to SHOCKS Active Vibration Control® System). English 7. To stop the tool, release the trigger switch. Always turn the tool off when work is finished and before unplugging. Hammerdrilling with a Core Bit (Fig. A, E) D25604, D25652 CAUTION: Do not use a core bit for hammerdrilling wood. Personal injury and damage to tool may result. NOTE: The D25831 and D25851 have only chipping modes with no hammerdrilling capability. 1. Set the mode selector 6 to hammerdrilling mode. 2. Adjust the side handle (front or rear position) 3 . 3. Assemble the centering bit and adapter shank into core bit. 4. Mark the spot where the hole is to be drilled. 5. Place the centering bit on that mark and depress the trigger switch 1 . NOTE: Some core drills require the removal of centering bit after about 1 cm of penetration. If so, remove and continue hammerdrilling. 6. When hammerdrilling through a structure thicker than the depth of the core bit, break away the round cylinder of concrete or core inside the bit at regular intervals. To avoid unwanted breaking away of concrete around the hole, first drill a hole the diameter of the centering bit completely through the structure. Then drill the cored hole halfway from each side of the structure. 7. To stop the tool, release the trigger switch. Always turn the tool off when work is finished and before unplugging. Chipping and Chiseling (Fig. A, E) D25831, D25851 1. Set the mode selector 6 to chipping mode. 2. Set the impact control dial 7 to desired setting (refer to Electronic Speed and Impact Control). 3. Insert the appropriate chisel and rotate it by hand to lock it into the desired position. NOTE: For SDS Max models, only use SDS Max bits. 4. Adjust the side handle (front or rear position) 3 . 5. Depress the trigger switch 1 . 6. Apply only enough pressure to engage active vibration control (refer to SHOCKS Active Vibration Control® System). 7. To stop the tool, release the trigger switch. Always turn the tool off when work is finished and before unplugging. 7
