Drill Operation; Maintenance - DeWalt DCD710 Manual

Be sure to tighten chuck with one hand on the chuck
sleeve and one hand holding the tool for maximum
tightness.
CHUCK REMOVAL (FIG. 6)
Turn the adjustment collar to the "drill" position and
gear shifter to position 1 (low speed). Tighten the
chuck around the shorter end of a hex key (not
supplied) of 6.35 mm (1/4") or greater size. Using
a wooden mallet or similar object, strike the longer
end in the clockwise direction, as shown. This will
loosen the screw inside the chuck.
Open chuck jaws fully, insert screwdriver (or Torx
tool if required) into front of chuck between jaws
to engage screw head. Remove screw by turning
clockwise (left-hand-thread). Place hex key in chuck
and tighten, as shown in Figure 6. Using a wooden
mallet or similar object, strike key sharply in the
counterclockwise direction. This will loosen the
chuck so that it can be unscrewed by hand.
CHUCK INSTALLATION (FIG. 7)
Screw the chuck on by hand as far as it will go
and insert screw (left-hand thread). Tighten screw
securely. Tighten the chuck around the shorter end
of a 6.35 mm (1/4") or larger hex key (not supplied)
strike the longer end in the clockwise direction with
a wooden mallet, as shown. Tighten the screw once
again by turning in a counterclockwise direction.

Drill Operation

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.
WARNING: To reduce the risk of
personal injury, ALWAYS ensure
workpiece is anchored or clamped
firmly. If drilling thin material, use a wood
"back-up" block to prevent damage to
the material.
Turn the collar to the drill bit symbol for drilling. Select
the desired speed/torque range using the gear
shifter to match the speed and torque to the planned
operation.
1. Use sharp drill bits only. For WOOD, use twist
drill bits, spade bits, or hole saws. For METAL,
use high-speed steel (HHS) twist drill bits or
hole saws.
2. 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.
3. Hold tool firmly with both hands to control the
twisting action of the drill.
WARNING: The drill may stall if
overloaded causing a sudden twist.
Always expect the stall. Grip the drill
firmly with both hands to control the
twisting action and avoid injury.
4. 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.
5. To minimize stalling or breaking through the
material, reduce pressure on drill and ease the
bit through the last fractional part of the hole.
6. Keep the motor running when pulling the bit
back out of a drilled hole. This will help prevent
jamming.
7. With variable speed drills there is no need to
center 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.
Operation as a Screwdriver
Select the desired speed/torque range using the
dual range gear shifter on the top of tool to match
the speed and torque to the planned operation.
Insert the desired fastener accessory into the chuck
as you would any drill bit. Make a few practice runs
in scrap or unseen areas to determine the proper
position of the clutch collar.
