DeWalt XR DCD771 User Manual

ENGLISH
3. 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.
4. Always apply pressure in a straight line with the bit. Use
enough pressure to keep drill biting, but do not push hard
enough to stall the motor or deflect thebit.
5. Hold tool firmly with both hands to control the twisting
action of the drill. If model is not equipped with side handle,
grip drill with one hand on the handle and one hand on the
batterypack.

CAUTION: 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.
6. IF DRILL STALLS, it is usually because it is being overloaded
or improperly used. RELEASE TRIGGER IMMEDIATELY,
remove drill bit from work, and determine cause of stalling.
DO NOT CLICK TRIGGER ON AND OFF IN AN ATTEMPT
TO START A STALLED DRILL — THIS CAN DAMAGE
THEDRILL.
7. To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the last
fractional part of thehole.
8. Keep the motor running when pulling the bit back out of a
drilled hole. This will help preventjamming.
9. With variable speed drills there is no need to centre punch
the point to be drilled. Use a slow speed to start the hole
and accelerate by squeezing the trigger harder when the
hole is deep enough to drill without the bit skippingout.

end of its technical life, discard it with due care for ourenvironment:
• Run the battery pack down completely, then remove it from
thetool.
• Li-Ion cells are recyclable. Take them to your dealer or a
local recycling station. The collected battery packs will be
recycled or disposed ofproperly.
MAINTENANCE
Your 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.
Hammerdrill Operation (Fig.F)
(DCD776)
1. Turn the collar
3
to the hammerdrillsymbol.
2. Select the high speed setting by sliding the selector back
(away from thechuck).
IMPORTANT: Use carbide-tipped or masonry bitsonly.
3. Drill with just enough force on the hammer to keep it from
bouncing excessively or “rising” off the bit. Too much force
will cause slower drilling speeds, overheating and lower
drillingrate.
4. 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.
5. 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.
NOTE: A smooth, even flow of dust from the hole indicates
proper drillingrate.
