ice center for recycling. If the new battery pack elicits the same trouble indication as the original, have charger tested at an authorized service center.

OPERATION

Installing and Removing the Battery Pack

NOTE: Make sure your battery pack is fully charged.

To install the battery pack into the tool handle, align FIG. 1A the base of the tool with the notch inside the tool’s handle (FIG. 1) and slide the battery pack firmly into the handle until you hear the lock snap into place as shown in FIG. 1A.

To remove the battery pack from the tool, press the release buttons and firmly pull the battery pack out of

the tool handle. Insert it into the charger as described in the charger section of this manu- al.

Variable Speed Switch (Fig. 2)

To turn the tool on, squeeze the trigger switch. To turn the tool off, release the trigger switch. Your tool is equipped with a brake. The chuck will stop as soon as the trigger switch is fully released.

The variable speed switch enables you to select the best speed for a particular application. The farther you squeeze the trigger, the faster the tool will operate. Use lower speeds for starting holes without a centerpunch, drilling in metals or plastics, driving screws and drilling ceramics, or in any application requiring high torque. Higher speeds are better for drilling in wood, wood compositions and for using abrasive and polishing accessories. For maximum tool life, use variable speed only for starting holes or fasteners.

NOTE: Continuous use in variable speed range is not recommended. It may damage the switch and should be avoided.

Forward/Reverse Control Button (Fig. 2)

A forward/reverse control button deter mines the direction the tool will spin and

also serves as a lock off button. To select forward rotation, release the trig-

ger switch and depress the forward/re- verse control button on the right side of the tool.To select reverse, depress the

forward/reverse control button on the left side of the tool. The center position of the control button locks the tool in the off position. When changing the position of the control button, be sure the trigger is released. NOTE: The first time the tool is run after changing the direc- tion of rotation, you may hear a click on start up. This is normal and does not indicate a problem.

Torque Adjustment Collar (Fig. 3)

Your tool has an adjustable torque screwdriver mechanism for FIG. 3 driving and removing a wide array of fastener shapes and sizes

and a hammer mechanism for drilling into masonry. Circling the collar are numbers, a drill bit symbol, and a hammer symbol.

These numbers are used to set the clutch to deliver a torque range. The higher the number on the collar, the higher the torque

and the larger the fastener which can be driven. To select any of the numbers, rotate until the desired number aligns with the arrow.

Dual Range Gearing (Fig. 3)

The dual range feature of your tool allows you to shift gears for greater versatility. To select the low speed, high torque setting, turn the tool off and permit to stop. Slide the gear shifter

forward (towards the chuck) (position 1), as shown. To select the high speed, low torque setting, turn the tool off and permit to stop. Slide the gear shifter back (away from chuck). NOTE Do not change gears when the tool is running. If you are having trouble changing gears, make sure that the dual range gear shifter is either completely pushed forward or completely pushed back.

Keyless Chuck (Fig. 4)

Your tool features a keyless chuck for greater FIG. 4 convenience. To insert a drill bit or other accessory, follow

the steps listed below.

1. Lock the trigger switch in the off position as described on page 6.

2.Grasp the rear half of the chuck with one hand and use your other hand to rotate the front half

counterclockwise, as shown. Rotate far enough so that the chuck opens sufficiently to accept the desired accessory.

3.Insert the bit or other accessory about 3/4” into the

chuck and tighten securely by holding the rear half of the chuck and rotating the front portion in the clockwise direction.

To release the accessory, repeat step 2 listed above.

WARNING: Do not attempt to tighten drill bits (or any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may result. Always lock off trigger switch when changing accessories.

Be sure to tighten chuck with two hands on both the rear sleeve and the forward sleeve for maximum tightness.

Single Sleeve Chuck

Some tools feature a keyless chuck with one plastic sleeve for one-handed operation of the chuck. To insert a drill bit or other accessory, follow the steps below.

1.Lock the trigger in the off position as described on page 6.

2.Grasp the black sleeve of the chuck with one hand and use the other hand to secure the tool as shown. Rotate the sleeve counterclockwise far enough so that the chuck opens sufficiently to accept the desired accessory.

3.Insert the accessory about 3/4” into the chuck and tighten securely by rotating the chuck sleeve clockwise with one hand while holding the tool with the other.

To release the accessory, repeat step 2 listed above.

WARNING: Do not attempt to tighten drill bits (or any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may result. Always lock off trigger switch when changing accessories.

Be sure to tighten chuck with one hand on the chuck sleeve and one hand holding the tool for maximum tightness.

NOTE: Do not install a single-sleeve chuck onto a tool that has a standare two-sleeve, key- less chuck. Tools originally built with a single sleeve chuck have an internal locking mech- anism that is not part of the chuck. Therefore, the single-sleeve chuck will not function properly on tools originally built with standard two-sleeve chucks.

Chuck Removal (Fig. 5)

Always wear eye protection.

Turn the adjustment collar to the “drill” position and low speed gear shifter position 1. Tighten the chuck around the shorter end of a hex key (not supplied) of 1/4” or greater size. Using a wooden mallet or similar object, strike the longer end in the clockwise direction, as shown. This will loosen the screw inside the chuck.

Open chuck jaws fully, insert screwdriver (or Torx tool if required) into front of chuck
