OPERATION

Instructions for Use

WARNING: Always observe the safety

instructions and applicable regulations.

WARNING: To reduce the risk

of serious personal injury, turn

tool off and disconnect tool from

power source before making any

adjustments or removing/installing

attachments or accessories.

Proper Hand Position (ﬁ g. 10)

WARNING: To reduce the risk of

serious personal injury, ALWAYS

use proper hand position as shown

in figure 10.

WARNING: To reduce the risk of

serious personal injury, ALWAYS hold

securely in anticipation of a sudden

reaction.

Proper hand position requires one hand on the main

handle (i), with the other hand on the side handle (h).

Drill Operation

1. Select the desired speed/torque range using

the gear shifter to match the speed and torque

to the planned operation. Set the mode control

collar to the drill symbol.

2. For WOOD, use twist bits, spade bits, power

auger bits or hole saws. For METAL, use high-

speed steel twist drill bits or hole saws. Use

a cutting lubricant when drilling metals. The

exceptions are cast iron and brass which should

be drilled dry.

3. Always apply pressure in a straight line with the

bit. Use enough pressure to keep the drill bit

biting, but do not push hard enough to stall the

motor or deflect the bit.

4. Hold tool firmly with both hands to control the

twisting action of the drill.

5. IF DRILL STALLS, it is usually because it

is being overloaded. RELEASE TRIGGER

IMMEDIATELY, remove drill bit from work,

and determine cause of stalling. DO NOT

CLICK TRIGGER OFF AND ON IN AN

ATTEMPT TO START A STALLED DRILL –

THIS CAN DAMAGE THE DRILL.

6. Keep the motor running when pulling the bit

back out of a drilled hole. This will help prevent

jamming.

Screwdriver Operation (ﬁ g. 4–6)

1. Select the desired speed/torque range using the

three-speed gear shifter (g) on the top of tool

to match the speed and torque to the planned

application. Initially set the torque adjustment

collar (e) at a lower setting to ensure the

fastener to be set to your specification.

NOTE: Use the lowest torque setting required

to seat the fastener at the desired depth. The

lower the number, the lower the torque output.

2. Rotate the mode control collar (f) so the screw

symbol is aligned with the arrow.

3. Reset the torque adjustment collar (e) to the

appropriate number setting for the torque

desired. Make a few practice runs in scrap or

unseen areas to determine the proper position

of the torque adjustment collar.

NOTE: The torque adjustment collar may be

set to any number at any time. However, the

torque adjustment collar is only engaged during

screwdriving mode and not in drill and hammerdrill

modes.

Hammerdrill Operation

1. Select the desired speed/torque range using

the gear shifter to match the speed and torque

to the planned operation. Set the mode control

collar to the hammer symbol.

2. When drilling, use just enough force on the

hammer to keep it from bouncing excessively.

Too much force will cause slower drilling

speeds, overheating, and a lower drilling rate.

3. Drill straight, keeping the bit at a right angle to

the work. Do not exert side pressure on the bit

when drilling as this will cause clogging of the

bit flutes and a slower drilling speed.

4. When drilling deep holes, if the hammer speed

starts to drop off, pull the bit partially out of

the hole with the tool still running to help clear

debris from the hole.

5. For masonry, use carbide-tipped masonry

bits. A smooth, even flow of dust indicates the

proper drilling rate.

MAINTENANCE

Your DEWALT power tool has been designed to

operate over a long period of time with a minimum

of maintenance. Continuous satisfactory operation

depends upon proper tool care and regular cleaning.
