Cleaning



WARNING: Blow dirt and dust out of all air vents with

clean, dry air at least once a week. To minimize the risk

of eye injury, always wear ANSI Z87.1‑approved eye

protection when performing thisprocedure.



WARNING: Never use solvents or other harsh

chemicals for cleaning the non‑metallic parts of the

tool. These chemicals may weaken the plastic materials

used in these parts. Use a cloth dampened only with

water and mild soap. Never let any liquid get inside the

tool; never immerse any part of the tool into aliquid.

MAINTENANCE



WARNING: To reduce the risk of serious personal

injury, turn unit off and remove the battery pack

before making any adjustments or removing/

installing attachments or accessories. An

accidental start‑up can causeinjury.

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.

• A smooth even flow of material indicates the proper

drillingrate.

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

Do not exert side pressure on the bit when drillling as

this will cause clogging of the bit flutes and a slower

drillingspeed.

• When drilling deep holes, if the hammer speed starts to

drop off, pull the bit partially out of the hole with tool still

running to help clear debris from thehole.

Recommendations for Screwdriving

• Start with lower torque settings, then advance to higher

torque settings to avoid damage to the workpiece

orfastener.

• Make some practice runs in scrap or on unseen areas of

the workpiece to determine the proper position of the

mode selectioncollar.

Drilling

IMPORTANT: For MASONRY, such as brick, cement, cinder

block, etc., use carbide‑tipped masonrybits.

1. Turn the mode selection collar

6

to the drillsymbol.

Refer to ModeSelection.

2. Place drill bit in contact with theworkpiece.

NOTE: Use sharp drill bitonly.

3. Pull the trigger switch applying pressure in a straight line

with the bit until it reaches the desireddepth.



WARNING: Drill may stall if overloaded causing a

sudden twist. Always expect the stall. Grip the drill

firmly to control the twisting action and avoidinjury.

4. Keep the motor running when pulling the bit back out of

a drilled hole to preventjamming.

Recommendations for Drilling

• When drilling, always apply pressure in a straight line

with the bit, but do not push hard enough to stall the

motor or deflect thebit.

• IF THE DRILL STALLS:

- RELEASE TRIGGER SWITCH IMMEDIATELY,

remove drill bit from work, and determine cause

ofstalling.

‑ DO NOT DEPRESS TRIGGER SWITCH ON AND OFF

IN AN ATTEMPT TO START A STALLED DRILL—

THIS CAN DAMAGE THEDRILL.

‑ To minimize stalling or breaking through the material,

reduce pressure on drill and ease the bit through the

last fractional part of thehole.

• Large holes (5/16" to 1/2" [7.9 mm to 12.7 mm]) in steel

can be made more easily if a pilot hole (5/32" to 3/16"

[4mm to 4.8 mm]) is drilledfirst.

• If drilling thin material or material that is prone to splinter,

use a wood “back‑up” block to prevent damage to

theworkpiece.

Hammerdrilling DCD798

IMPORTANT: Use carbide‑tipped or masonry bits rated for

percussion drillingonly.

1. Select the desired speed/torque range using the speed

selector

7

to match the speed and torque to the

planned operation. Turn the mode selection collar

6

to

the hammerdrillsymbol.

2. Pull the trigger, applying just enough pressure on the

hammer to keep it from bouncing excessively or "rising"

off the bit.

Recommendations for Hammerdrilling

• Too much force will cause slower drilling speeds,

overheating, and a lower drillingrate.
