Using Control Switch

WARNING

To reduce the risk of injury, wear safety goggles or glasses with side shields.

Using Keyless Chucks

Your cordless 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.

Sleeve

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 se- cure when the chuck makes a ratcheting sound and the sleeve can not be rotated any further.

Selecting Speed

High

The speed selector is on top of the motor housing. Allow the tool to come to a complete stop before changing speeds. See “Ap- plications” for recommended speeds under various conditions.

1.For Low speed (up to 600 RPM), push the speed selector to the left.

2.For High speed (up to 1800 RPM), push the speed selector to the right.

Selecting Hammer or Drill Action

MILWAUKEE Hammer-Drills are designed for three operating modes: drilling with hammering action, drilling only, and driving screws. To set the operating mode, rotate the hammer/drill selector collar and torque selector collar to the desired symbols.

1.To use the hammer-drilling mode (Fig. 6), rotate the hammer/drill selector

collar until the hammer symbol ap- pears in line with the arrow. Then rotate the Torque selector collar until the drill

symbol appears in line with the ar- row. Apply pressure to the bit to engage the hammering mechanism.

rotate the hammer/drill selector collar

until the drill symbol

appears in line

with the arrow. Then rotate the Torque

selector collar until the drill symbol

appears in line with the arrow.

3.To use the driving screws mode (Fig. 8), rotate the hammer/drill selector

collar until the drill symbol appears in line with the arrow. Then rotate the torque selector collar until the desired clutch setting appears in line with the arrow.

Fig. 8

To Drive Screws

The adjustable clutch ,when properly ad- justed, will slip at a preset torque to prevent driving the screw too deep into different materials and to prevent damage to the screw or tool.

The torque specifications shown here are approximate values.

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 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. 9). Check the direction of rotation before use.

Fig. 9

Push in for forward

For reverse (counterclockwise) rotation, push in the control switch from the left side of the tool (Fig. 10). Check direction of rotation before use.

Fig. 10

Push in for reverse

To lock the trigger, push the control switch to the center position (Fig. 11). 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 maintenance, changing acces- sories, storing the tool and any time the tool is not in use.

3.To remove the bit, turn the sleeve in the counterclockwise 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.

NOTE: When using carbide bits, do not use water to settle dust. Do not attempt to drill through steel reinforcing rods. This will dam- age the carbide bits.
