Drill Operation - DeWalt DCD716D2 Original Instructions Manual

To select the low speed, high torque setting, turn the tool off
and permit to stop. Slide the gear shifter
the chuck). To select the high speed, low torque setting, turn
the tool off and permit to stop. Slide the gear shifter back (away
from chuck).
nOTE: Do not change gears when the tool is running. If you are
having trouble changing gears, make sure that the dual range
gear shifter is either completely pushed forward or completely
pushed back.
Keyless Single Sleeve Chuck (Fig. A, D)
Your tool features a keyless chuck
one-handed operation of the chuck. To insert a drill bit or other
accessory, follow these steps.
1. Lock the trigger in the OFF position as previously described.
2. Grasp the black sleeve of the chuck
and use the other hand to secure the tool. Rotate the
sleeve counterclockwise far enough to accept the
desired accessory.
3. Insert the accessory about 19 mm into the chuck and
tighten securely by rotating the chuck sleeve clockwise with
one hand while holding the tool with the other. Your tool is
equipped with an automatic spindle lock mechanism. This
allows you to open and close the chuck with one hand.
To release the accessory, repeat step 2 above.

WARNING: Do not attempt to tighten drill bits (or any
other accessory) by gripping the front part of the chuck
and turning the tool on. Damage to the chuck and
personal injury may result. Always lock off trigger switch
when changing acces sories.
Be sure to tighten chuck with one hand on the chuck sleeve and
one hand holding the tool for maximum tightness.
Chuck Removal (Fig. E)
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 mm 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 E. 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. F)
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 mm 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 battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can cause injury.

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.

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.
Screwdriver Operation
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.
