Power tool maker Ryobi launched the first affordable portable benchtop planer, the AP10. The company has brought a number of other products within reach of the do-it-yourself enthusiast. The BT3000 was the first affordable, precision woodcutting system, and the 18v Super Combo was the first cheap cordless power tool system in which a number of tools shared the same battery, including the drill. In addition to the low initial purchase price, Ryobi tools have extensive consumer-serviceable maintenance features, which helps keep ownership costs low. One of these features is the easily removable chuck in its drills.
Lock the drill's trigger switch. Place the selector that changes the direction of rotation in the center position. The switch is adjacent to the trigger.
Insert the 5/16" hex key into the chuck and tighten the jaws. Get them as tight as possible.
Tap the hex key with the mallet in a clockwise direction. Tap the hex key quite sharply. The screw inside the chuck will loosen.
Open the chuck jaws and take out the hex key. Use the screwdriver to unscrew the screw. It has left-hand threads and unscrews in a clockwise direction.
Put the hex key back into the chuck and tighten the jaws again. Tap the hex key with the mallet—this time in a counter-clockwise direction. The chuck will loosen.
Unscrew the chuck by hand.
