OPERATION
WARNING Always remove battery pack before changing or removing ac- cessories. Only use accessories specifically recommended for this tool. Others may be
hazardous.
WARNING To reduce the risk of injury, wear safety goggles or glasses with side
shields.
Using Keyless Chucks
This tool is equipped with a spindle lock. The chuck can be tightened with one hand, creating higher grip strengths on the bit.
Always remove the battery pack or lock the trigger before inserting or removing bits.
1.To open the chuck jaws, turn the sleeve in the counterclockwise direction.
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, turn the sleeve in the clockwise direction. The bit is secure when the chuck makes a ratcheting sound and the sleeve can not be rotated any further.
3.To remove the bit, turn the sleeve in the coun- terclockwise direction.
NOTE: A ratcheting sound may be heard when the chuck is opened or closed. This noise is part of the locking feature, and does not indicate a problem with the chuck's operation.
Using the Adjustable Clutch
This tool has an adjustable clutch for driving differ- ent types of screws into different materials. When properly adjusted, the clutch will slip at a preset torque to prevent driving the screw too deep and to prevent damage to the screw or tool.
To adjust the clutch, turn the clutch adjusting ring so that the desired setting

NOTE: Because the settings shown in the table are only a guide, use a piece of scrap material to test the different clutch settings before driving screws into the workpiece.
Selecting Speed
The speed selector is on top of the motor housing. Allow the tool to come to a complete stop before changing speeds. See “Applications” for recom- mended speeds under various conditions.
1.For Low speed (up to 350 RPM), push the speed selector to the left (“1” is displayed).
2.For High speed (up to 1400 RPM), push the speed selector to the right (“2” is displayed).

High = 2
Using Control Switch
The control switch may be set to three positions: forward, reverse and lock. Due to a lockout mecha- nism, the control switch can only be adjusted when the ON/OFF switch is not pressed. Always allow the motor to come to a complete stop before using the control switch.

Push to center position to lock trigger
For forward (clockwise) rotation, push in the control switch from the right side of the tool (Fig. 4). Check the direction of rotation before use.
For reverse (counterclockwise) rotation, push in the control switch from the left side of the tool (Fig. 5).
Check direction of rotation before use.
To lock the trigger, push the control switch to the center position (Fig. 6). The trigger will not work while the control switch is in the center locked posi- tion. Always lock the trigger or remove the battery pack before performing maintenance, changing accessories, storing the tool and any time the tool is not in use.
Starting, Stopping and Controlling Speed
1.To start the tool, grasp the handle firmly and pull the trigger.
NOTE: An LED is turned on when the trigger is pulled. It will go off when the trigger is re- leased.
2.To vary the speed, increase or decrease the pressure on the trigger. The further the trigger is pulled, the greater the speed.
3.To stop the tool, release the trigger. Make sure the bit comes to a complete stop before laying the tool down.
Drilling
Set the torque selector collars to the drill position. Place the bit on the work surface and apply firm pressure before starting. Too much pressure will slow the bit and reduce drilling efficiency. Too little pressure will cause the bit to slide over the work area and dull the point of the bit.
If the tool begins to stall, reduce pressure slightly to allow the bit to regain speed. If the bit binds, reverse the motor to free the bit from the workpiece.
APPLICATIONS
WARNING To reduce the risk of electric shock, check work area for hidden pipes
and wires before drilling or driving screws.
Drilling in Wood, Composition Materials and Plastic
When drilling in wood, composition materials and plastic, start the drill slowly, gradually increasing speed as you drill. When drilling into wood, use wood augers or twist drill bits. Always use sharp bits. When using twist drill bits, pull the bit out of the hole frequently to clear chips from the bit flutes. To reduce the chance of splintering, back work with a piece of scrap wood. Select low speeds for plastics with a low melting point.
Drilling in Metal
When drilling in metal, use high speed steel twist drills or hole saws. Use a center punch to start the hole. Lubricate drill bits with cutting oil when drilling in iron or steel. Use a coolant when drilling in non- ferrous metals such as copper, brass or aluminum. Back the material to prevent binding and distortion on breakthrough.
Driving Screws and Nut Running
Drill a pilot hole when driving screws into thick or hard materials. Set the torque selector collar to the proper position and set the speed to low. Use the proper style and size screwdriver bit for the type of screw you are using.
With the screwdriver bit in the screw, place the tip of the screw on the workpiece and apply firm pressure before pulling the trigger. Screws can be removed by reversing the motor.
