When using drill bits, allow the bit to strike the bottom of the chuck. Center the bit in the chuck jaws and lift it about 1/16" off of the bottom.

When using screwdriver bits, insert the bit far enough for the chuck jaws to grip the hex of the bit.

2.To close the chuck jaws, hold the collar while turning the sleeve in the clock- wise direction. Tighten securely.

NOTE: If the spindle rotates when opening or closing the chuck jaws, grasp the chuck and slightly rotate back and forth to en- gage the spindle-lock mechanism.

The spindle will remain locked until the tool is turned on. The spindle-lock mechanism will automatically disengage when the tool is turned on.

WARNING!

To reduce the risk of injury, al- ways wear eye protection.

Chuck Removal (Fig. 7)

This tool is equipped with a threaded spindle to hold the chuck. Before removing the chuck, unplug the tool and open the chuck jaws. A left-handed thread screw is lo- cated inside the chuck to prevent the chuck from loosening when the tool is operated in reverse direction. Remove the screw by turning it clockwise. To remove the chuck, hold the tool so that only the side of the chuck rests firmly and squarely on a solid workbench. Insert the chuck key or a chuck remover bar in one of the keyholes. Turn the chuck so the key is at about a 30° angle to the bench top and strike the key sharply with a hammer so the chuck turns in a counterclockwise direction (looking from

the front of the tool). This should loosen the chuck from the spindle which has a right hand thread making it easy to remove the chuck by hand.

NOTE: When replacing the chuck, always replace the left hand thread screw in the chuck.

1.Remove the chuck from the drill follow- ing instructions (See “Removing the Chuck From the Drill”). Slip the double hex coupling (1) over the hex on the drill spindle.

Loosen the clamping screws on the clamping sleeve (2) and slip the sleeve onto the drill collar.

2.Slide the Right Angle Drive head (4) into the other side of the sleeve and turn the drive head slightly in either direc- tion so the hexagonal hole in the cou- pling (1) engages the hexagonal por- tion of the spindle (3).

NOTE: Attaching the drill chuck to the side marked “LOW” reduces the speed by 1/3, or 33%. Attaching the drill chuck to the opposite side increases the speed by 50%.

3.When assembled, turn the Right Angle Drive head to the desired position and tighten the clamping screws to secure the unit. Thread the chuck onto the Right Angle Drive spindle (5). INSTALL CHUCK LOCKING SCREW.

Removing the Chuck From Right Angle Drive Unit (Fig. 9)

Fig. 9

The chuck can be removed from the Right Angle Drive Unit in the same manner it is removed from the drill; however, ALWAYS REMOVE RIGHTANGLE DRIVE FROM THE DRILL BEFORE ATTEMPTING TO LOOSEN THE CHUCK. This will prevent damaging the drill's gearing. Use the open end wrench provided to hold the Right Angle Drive spindle before attempting to loosen the chuck.
