manual abstract


The soft start feature also reduces the immediate torque reaction transmitted to the gearing and the operator if the hammer is G All rotary hammers are equipped with a torque limiting clutch that reduces the maximum torque reaction transmitted to the operator in the case of a jamming drill bit. This feature also prevents the gearing and motor from stalling. The torque limiting clutch has been factory set Electronic Speed and Impact Control The electronic speed and impact control allows the use of smaller drill English 582429-00/D25500 etc 1/29/03 9:29 AM Page 6 English bits without the risk of bit breakage, materials without shattering, and optimal chiseling. To set the control dial, turn the dial to the desired higher the number, the greater the speed and impact energy. Dial settings make the tool extremely flexible and different applications. The required setting depends on the bit size and hardness of material being drilled. Mode Selector (Fig. 6 & 7) Your rotary hammer (all units except D25550) can be used in two operating modes. In hammer drilling mode, the tool simultaneously rotates and impacts the work. This mode is appropriate for all concrete and masonry operations. In the FIG. 7 FIG. 6 hammering-only mode, the spindle-lock on the tool is engaged. The tool only impacts the work without rotating. This mode is appropriate for light chipping, chiseling and demolition applications. NOTE: In impact-only mode, the hammer can also be used as a lever to free a jammed drill bit. To select the required operating mode, rotate the selector lever over the safety lock until it covers the correct symbol. SERVICE AND POWER INDICATOR LEDS (D25600, D25650) The red service indicator LED lights up when the carbon brushes are nearly worn out to indicate that the tool needs servicing. After approximately 8 hours of use the motor will automatically be shut off. Take the tool to a DEWALT service location for routine inspection and maintenance. DRILLING WITH A SOLID BIT 1. Set the speed and impact control dial. 2. Set the model selector to the “hammer drilling” position (for all units except D25550). 3. Insert the appropriate drill bit. 4. Fit and adjust the side handle. 5. If necessary, set the drilling depth rod. 6. Mark the spot where the hole is to be 7. Place the drill bit on the spot and press the 8. Push with only enough force so that the hammer The hammer only needs enough pressure or mechanism. Pushing harder will not make the hammer 9. To stop the tool, release the ON/OFF switch. Always when work is finished and before unplugging. DRILLING WITH A CORE BIT 1. Turn the speed and impact control dial to the maximum torque position. (D25550, D25500, D25551, D25600, D25650, ) 2. Set the model selector to the “hammer drilling,” position (for all units except D25550). 3. Fit and adjust the side handle. 4. Assemble the centering bit and adapter shank into core bit. 5. Mark the spot where the hole is to be drilled. 6. Place the centering bit on the spot and press the ON/OFF switch. NOTE: Some core drills require the removal of centering bit after about 1 cm of penetration. If so, remove and continue d...
