The speed selector is on top of the motor housing. Allow the tool to come to a com- plete stop before changing speeds. See “Applications” for recommended speeds under various conditions.
1.For Low speed (up to 400 RPM), push the speed selector back, displaying the "1" for low.
2.For High speed (up to 1400 RPM), push the speed selector forward, display- ing the "2" for high.
Using Control Switch (Fig. 8, 9 and 10)
will not work while the control switch is in the center locked position. Always lock the trigger or remove the battery pack before performing maintenance, changing acces- sories, storing the tool and any time the tool is not in use.

Starting, Stopping & Controlling Speed
1. | To start the tool, pull the trigger. |
2. | To stop the tool, release the trigger |
| and an electric brake stops the tool |
| instantly. |
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 Materi- als and Plastic
When drilling in wood, composition materi- als and plastic, start the drill slowly, gradu- ally 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 splin- tering, back work with a piece of scrap wood. Select low speeds for plastics with a low melting point.
Overloading
Continuous overloading may cause per- manent damage to tool or battery pack.
WARNING!
High rotational force. To reduce the risk of injury, always hold or brace securely.
Bit Binding
A high rotational force occurs when a bit binds. If the bit binds, the tool will be forced in the opposite direction of the bit rotation. Bits may bind if they are misaligned or when they are breaking through a hole. Wood boring bits can also bind if they run into nails or knots. Be prepared for bit binding situations.
The control switch may be set to three positions: forward, reverse and lock. Due to a lockout mechanism, the control switch can only be adjusted when the ON/OFF switch is not depressed. Always allow the motor to come to a complete stop before using the control switch.
For forward (clockwise) rotation, push in the control switch from the right side of the tool (Fig. 8). Check the direction of rota- tion before use.

Push in for forward
For reverse (counterclockwise) rotation, push in the control switch from the left side of the tool (Fig. 9). Check direction of rotation before use.

All models feature variable speed control. To vary the speed, increase or decrease pressure on the trigger. The further the trigger is pulled, the greater the speed.
Drilling
Set the torque selector collar to the drill position
Place the bit on the work surface and ap- ply firm pressure before starting. Too much pressure will slow the bit and reduce drill- ing 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.
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 nonferrous 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 se- lector 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 trig- ger. Screws can be removed by reversing the motor.
To reduce the chance of bit binding:
•Use sharp bits. Sharp bits are less likely to bind when drilling.
•Use the proper bit for the job. There are bits that are designed for specific purposes.
•Use caution when drilling pitchy, knotty, wet or warped material or when drilling in material that may con- tain nails, screws, staples, etc.
