Applications

Using Control Switch

The control switch may be set to three posi-

Starting, Stopping and Controlling Speed

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. 8). Check the direction of rotation 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 rota- tion before use.

Push in for reverse

To lock the trigger, push the control switch to the center position (Fig. 10). 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.

1.To start the tool, grasp the handle ﬁrmly and pull the trigger.

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 both the hammer/drill and torque selector collars to the drill positions.

Place the bit on the work surface and ap- ply 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.

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 cut- ting 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.

Drilling in Masonry

When drilling in masonry, select the hammer- drill operating mode (hammer-drills only). Use high speed carbide-tipped bits. Drilling soft masonry materials such as cinder block requires little pressure. Hard materials like concrete require more pressure. A smooth, even ﬂow of dust indicates the proper drill- ing rate. Do not let the bit spin in the hole without cutting. Do not use water to settle dust or to cool bit. Both actions will damage the carbide.

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.

Overloading

Continuous overloading may cause perma- nent damage to tool or battery pack.
