Milwaukee 2401-20 manual Applications

Using the Adjustable Clutch

This tool has an adjustable clutch for driving different types of screws into different materi- als. 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 (1-15) lines up with the arrow on the motor housing, as shown.

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.

Using Control Switch

The control switch may be set to three posi- tions: forward, reverse and lock. Due to a lockout mechanism, 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.

For forward (clockwise) rotation, push in the control switch from the right side of the tool. Check the direction of rotation before use.

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

To lock the trigger, push the control switch to the center position. The trigger will not work while the control switch is in the center locked position. Always lock the trigger or remove the battery pack before performing mainte- nance, changing accessories, storing the tool and any time the tool is not in use.

Battery Pack Protection

To protect the battery from damage and extend its life, the tool's intelligent circuit monitors current draw, temperature, and voltage drops.

In extremely high torque, binding, stalling, and short circuit situations that cause high current draw, the tool will vibrate for about 5 seconds, the fuel gauge will flash, and then the tool will turn OFF. To reset, release the trigger.

Under extreme circumstances, the internal temperature of the battery could become too high. If this happens, the fuel gauge will flash and the battery pack will shut off. Let the bat- tery pack cool and then continue work.

APPLICATIONS

WARNING

To reduce the risk of electric shock, check work area for hidden pipes and wires before drilling or driving screws.

This tool provides a quick, convenient means of drilling small holes and installing and removing screws. Because of the many screw sizes, types, thread engagements and materials available, it is difficult to limit the ap- plication of this tool by screw size. However, for applications in wood, a #6 wood screw with a full pilot hole is recommended as a practical limit.

Drilling in Wood, Composition Materials and Plastic

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.

Driving Screws

Drill a pilot hole when driving screws into thick or hard materials. Set the clutch ad- justing ring 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 pressing the foward/reverse switch up. Screws can be removed by pressing the foward/reverse switch down.

Locking the Screwdriver Bit

When the tool is off, the screwdriver bit automatically locks in place allowing you to use the screwdriver manually. Do this to tighten screws that require more torque than the driver is capable of delivering, when confirming the tightness of a screw or when loosening an extremely tight screw.
