OPERATION SDS CHUCK See Figures 4 - 5. The rotary hammer has an SDS chuck that is used with SDS bits. A keyless chuck is also supplied with the rotary hammer. The rotary hammer can be used with just the SDS chuck or with the supplied keyless chuck installed into the SDS chuck. To install chuck and bits into the SDS chuck: Unplug the rotary hammer. Slide the chuck body down. Install the SDS chuck or bit into the chuck. Release the chuck body. Once the keyless chuck has been installed into the SDS chuck, the keyless chuck can now be used with standard drill bits. The keyless chuck makes it simple to tighten or release drill bits in the chuck jaws. Grasp and hold the collar of the chuck with one hand. Rotate the chuck body with your other hand. The arrows on the chuck indicate which direction to rotate the chuck body in order to GRIP (tighten) or RELEASE the drill bit. WARNING: Do not hold the chuck body with one hand and use the power of the rotary hammer to tighten the chuck jaws on the drill bit. The chuck body could slip in your hand, or your hand could slip and come in contact with the rotating drill bit. This could cause an accident resulting in serious personal injury. WARNING: Always unplug the tool when installing or removing bits, adjusting settings, or when the tool is not in use. Failure to unplug the tool may result in accidental starting and serious personal injury. INSTALLING BITS IN KEYLESS CHUCK See Figures 5 - 6. Unplug the rotary hammer. Open or close the chuck jaws to a point where the opening is slightly larger than the bit size you intend to use. Also, raise the front of the rotary hammer slightly to keep the bit from falling out of the chuck jaws. Insert the drill bit. Tighten the chuck jaws securely on the bit. NOTE: Rotate the chuck body in the direction of the arrow marked GRIP to close the chuck jaws. Do not use a wrench to tighten or loosen the chuck jaws. REMOVING BITS See Figure 5. Unplug the rotary hammer. Open the chuck jaws. Note: Rotate the chuck body in the direction of the arrow marked RELEASE to open the chuck jaws. Do not use a wrench to tighten or loosen the chuck jaws.
