3. Insert the Battery into the charger by aligning the rib on the Battery with the groove in the charger. Press the Battery into place.The Red LED will illuminate indicating that a Battery is charging. 4. NOTE: During recharging, the Battery will become slightly warm to the touch. This is normal and not a cause for concern. Do not keep the Battery or charger in an environment of extreme heat or cold. They will work best at room temperature. 5. The Red LED will remain on for approximately 1 hour while the Battery charges. When the Battery is fully charged the charger will stop charging, the Red LED will go out, and the Green LED will illuminate indicating that the Battery is fully charged. 6. When the Battery is fully charged, remove the charged battery from the charger, and unplug the charger from its power source. Put the charger away for safekeeping. Do not leave the Battery in the charger indefinitely. Installing the Battery 1. Slide the Battery into the base of the handle. CAUTION: Do not press the battery into the handle if it is not properly aligned, as this may damage the body of the tool, and will not secure the battery. 2. Be sure the Battery is properly installed before using the tool. Installing the Battery Pack SKU 93722 For technical questions please call 1-800-444-3353 Page 6 Using the battery locks and Removing the Battery 1. After placing the Battery in the tool, battery locks on the side of the Battery engage to prevent the battery from coming out accidentally. 2. To remove the Battery, depress the battery locks and remove the Battery by pulling straight out. Special Drive System (SDS) SDS bits use a cylindrical shank, with indents held by the chuck. To install a bit, pull the Chuck back, insert the bit, then press the chuck forward to lock the bit in place. To remove the bit, pull the Chuck back, pull the bit straight out, and release the Chuck. The SDS system has the advantage of a spring-loaded chuck, so that bits can be chucked with a simple and quick hand action. Further, the bit and chuck are uniquely suited to hammer drilling in stone and concrete. While the drill bit is held solidly in the chuck, it can slide forward and back like a piston. The hammer of the drill acts to accelerate only the drill bit itself, and not the large mass of the chuck. That makes hammer drilling with an SDS-plus drill bit much more productive than with other types of bits. SDS bits are most often used for masonry drilling, for which hammer drilling action is most helpful. SDS bits use sliding keyways that open to the end of the bit, which mate with keys in the chuck. There are additional indents on the bit that are grasped by the chuck to prevent the drill bit falling out. The hammer of the drill hits the flat end of the bit. NOTE: To allow the bit to freely slide in the chuck, the shank of the bit must be lubricated with grease. SDS is available in three sizes, SDS, SDS-plus, and SDS-max. SDS-plus is the most common type, with masonry drills from 5 mm diameter to 30 mm diameter ordinarily available. The shortest SDS-plus masonry drill bits are about 110 mm overall length, and the longest 1000 mm. If extra long bits are used, a shorter bit must be used first to start the hole. CAUTION: Use only SDS-Plus bits with this tool. SDS-plus chuck operation SKU 93722 For technical questions please call 1-800-444-3353 Page 7 Operation For use as a Hammer Drill: CAUTION: Use only impact grade SDS-Plus bits, designed for SDS-Plus hammer drills. Standard bits will not be properly held by this Chuck, and may break under the force created by this tool. SDS-Plus impact grade bits are available from Harbor Freight Tools. 1. The Auxiliary Handle must be installed for additional stability when Hammer Drilling. Always use both hands to hold this tool during hammer drill operation. To install Auxiliary Handle, slide the Auxiliary Handle Assembly (32) over the Front Housing (24). Tighten the screw in the Handle Assemble to lock in place. Adjust the length of the Depth Gauge Rod to stop the drilling process when the correct hole depth is reached. Tighten the Depth Gauge Rod in place by tightening the screw in the Auxiliary Handle Assembly. 2. This tool has three settings, Drill Only, Hammer Only and Hammer Drill. Select the proper setting for the work you will do. Be sure the tool has come to a complete stop before moving the selector to another setting. Move the Function Selector to the Hammer Drill setting. Please see picture on page 9 for reference. This setting will allow the drill to hammer as well as turn. 3. Press the Forward-Reverse Switch (61) to the right for forward drilling, press it to the left for reverse drilling. 4. The speed of the tool is controlled by squeezing the Trigger (60). Progressively increase or decrease pressure on the Trigger to make the tool operate faster or slower. 5. The Hammer Drill is best suited for drilling into hard materials such as concrete or masonry.
