offered by DeWALT, have not been tested with this
product, use of such accessories with this tool could be
hazardous. To reduce the risk of injury, only DeWALT
recommended accessories should be used with
thisproduct.
Recommended accessories for use with your tool are
available at extra cost from your local dealer or authorized
service center. If you need assistance in locating any
accessory, please contact DeWALT call 1-800-4-DeWALT

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.
Hammerdrilling DCD805
IMPORTANT: Use carbide-tipped or masonry bits rated for
percussion drillingonly.
1. Select the desired speed/torque range using the speed
selector
8
to match the speed and torque to the
planned operation. Turn the mode selection collar
5
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.
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.
Screwdriving
Your tool has a clutch with adjustable torque for driving
and removing a wide array of fastener shapes and sizes. The
numbers 1–15 on the mode selection collar
5
are used to
set a torque range for screwdriving. The higher the number
on the collar, the higher the torque and the larger the
fastener which can bedriven.
1. Turn the mode selection collar
5
to the desiredposition.
Refer to Mode Selection.
2. Pull the trigger switch applying pressure in a straight line
with the bit until the fastener is seated at the desired
depth in theworkpiece.
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
5
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 easier 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.
