Avoid running the drill/driver at low speeds for extended periods of time. Running at low
speeds under constant usage may cause the drill/driver to become overheated. If this
occurs, cool the drill/driver by running it without a load and at full speed.
KEYLESS CHUCK (Fig. 9 and 9a)
The drill/driver has a keyless chuck which allows you to hand tighten or loosen accessory bits
without the use of a chuck key.
1. Grasp and hold the rear chuck collar with one hand (see Fig. 9).
2. Rotate the front of the chuck with your other hand, clockwise to CLOSE and
counterclockwise to OPEN the chuck jaws (as viewed from the front of the chuck).
The front of the chuck also has embossed "pointing hands", indicating which direction to
rotate the front of the chuck to GRIP (tighten) or RELEASE (loosen) the accessory bits in
the chuck jaws (see Fig. 9a).

continue to tighten the screw.
,, Repeat this process until you reach a torque setting that drives and tightens the screw
without the clutch ratcheting.
,, Use that torque setting to drive and tighten the remaining screws.
