OPERATION

WARNING

To reduce the risk of injury, always

wear safety goggles or glasses

with side shields.

Using Forward/Reverse Switch

1. For forward (clockwise)

Front of Tool

rotation, push the for-

ward/reverse switch to

the left position as

shown.

2. For reverse (coun-

terclockwise) rotation,

push the forward/re-

verse switch to the

right position as shown.

Although an interlock

prevents reversing the

tool while the motor

is running, allow it to

come to a full stop be-

fore reversing.

WARNING

To reduce the risk of injury, keep

hands and cord away from the bit

and all moving parts.

Starting, Stopping and Controlling Speed

1. To start the tool, pull the trigger.

2. To stop the tool, release the trigger.

3. To vary the drilling speed, simply increase or

decrease pressure on the trigger. The further the

trigger is pulled, the greater the speed.

Locking Trigger

The lock button holds the trigger in the ON position

for continuous full speed use.

1. To lock the trigger, hold the lock button in while

pulling the trigger. Release the trigger.

2. To unlock the trigger, pull the trigger and release.

The lock button will pop out.

NR = Not recommended

WARNING

To reduce the risk of explosion,

electric shock and property dam-

age, always check the work area for hidden pipes

and wires before drilling.

Selecting Bits

When selecting a bit, use the right type for your job.

For best performance, always use sharp bits.

Drilling

1. Before drilling, be sure the workpiece is clamped

securely. Use backing material to prevent damage

to the workpiece during breakthrough.

2. When starting a hole, place the drill bit on the work

surface and apply rm pressure. Begin drilling at

a slow speed, gradually increasing the speed as

you drill.

3. Always apply pressure in line with the bit. Use

enough pressure to keep the drill biting, but do

not push hard enough to stall the motor.

4. Reduce pressure and ease the bit through the last

part of the hole. While the tool is still running, pull

the bit out of the hole to prevent jamming.

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 using twist drill bits, pull

the bit out of the hole frequently to clear chips from

the bit utes. Use low speeds for plastics with a low

melting point.

Drilling in Masonry

When drilling in masonry, 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

ow of dust indicates the proper drilling 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.

Drilling in Metal

When drilling in metal, use high speed steel twist drills

or hole saws. Use slow speeds for hard metals and

high speeds for softer metals. 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

When driving screws, use the proper screwdriver bit

for your job. After drilling pilot and shank holes, start

the screw slowly and increase the speed as driving

progresses. Set the screw by slowing to a stop. Do

not run screws down at excessive speeds. To remove

screws, reverse the motor.
