Variable Speed Trigger Switch (Fig. A) Depressing the variable speed trigger switch 4 turns the tool on, releasing the variable speed trigger switch turns the tool off. The variable speed trigger switch permits speed control-the farther the trigger is depressed, the higher the speed of the drill. Forward/Reverse Button (Fig. A) A forward/reverse button 3 determines the direction of the tool. It is located in front of the trigger switch. To select forward rotation, release the trigger switch 4 and depress the forward/reverse button on the right side of the tool. To select reverse, depress the forward/reverse button on the left side of the tool. When changing the position of the button, be sure the trigger is released. NOTE: The first time the tool is run after changing the direction of rotation, you may hear a click on start up. This is normal and does not indicate a problem. Keyed Chuck Open the chuck jaws by turning collar by hand and insert the shank of the bit about 3/4" (19 mm) into chuck. Tighten the chuck collar by hand. Place chuck key ( 10 , Fig. A) in each of the three holes, and tighten in clockwise direction. It's important to tighten chuck with all three holes. To release the bit, turn the chuck counterclockwise in just one hole, then loosen the chuck by hand. NOTE: When using hex shank or three-sided shank bits, be sure to align the flat sides of the bit with the chuck jaws to ensure the bit is properly engaged by the jaws. Removal of Keyed Chuck (Fig. G) Remove the left-handed chuck screw using a T25 torx wrench, rotating clockwise to loosen.Tighten the chuck around the shorter end of a hex wrench (not supplied) of 3/8" (10 mm) size. With the tool braced securely, use a soft hammer and strike the hex wrench sharply in the counterclockwise direction when viewed from the front of the tool. This will loosen the chuck so that it can be removed by hand. Keyed Chuck Installation (Fig. H) Screw the chuck on by hand as far as it will go. Insert the shorter end of a hex wrench (not supplied) of 3/8" (10 mm) size and strike it in the clockwise direction with a soft hammer. Reinstall the left handed clutch screw. FIG. G FIG. H English Worklight (Fig. A) CAUTION: Do not stare into worklight. Serious eye injury could result. The worklight 9 is located on the foot of the tool. The worklight is activated when the trigger switch is depressed, and will automatically turn off 20 seconds after the trigger switch is released. If the trigger switch remains depressed, the worklight will remain on. NOTE: The worklight is for lighting the immediate work surface and is not intended to be used as a flashlight. OPERATION WARNING: To reduce the risk of serious personal injury, turn unit off and remove the battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental start-up can cause injury. Installing and Removing the Battery Pack (Fig. I) NOTE: For best results, make sure your battery pack is fully charged. To install the battery pack 12 into the tool handle, align the battery pack with the rails inside the tool's handle and slide it into the handle until the battery pack is firmly seated in the tool and ensure that it does not disengage. To remove the battery pack from the tool, press the release button 13 and firmly pull the battery pack out of the tool handle. Insert it into the charger as described in the charger section of this manual. Squeeze the tool trigger for three seconds to dissipate the slight electric charge that may still be in the tool. The worklight may come on for a brief moment. Fig. I 12 13 Proper Hand Position (Fig. J) WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position as shown.
