DeWalt DWC709 Instruction Manual page 39

NOTE: Continuous use in variable speed range is not recommended.
It may damage the switch and should be avoided.
Forward/Reverse Control Button (Fig. 4)
A forward/reverse control button (B) determines the direction of the
tool and also serves as a lock off button.
To select forward rotation, release the trigger switch and depress
the forward/reverse control button on the right side of the tool.
To select reverse, depress the forward/reverse control button on
the left side of the tool. The center position of the control button locks
the tool in the off position. When changing the position of the control
button, be sure the trigger is released.
NOTE: The first time the tool is run after changing the direction of
rotation, you may hear a click on start up. This is normal and does
not indicate a problem.
Torque Adjustment Collar (Fig. 5)
The torque adjustment collar (C) is clearly
marked with numbers and a drill bit
symbol. The collar should be rotated until
the desired setting is located at the top of
the tool. Locators are provided in the collar
to eliminate the guess work when selecting
fastening torque. The higher the number
on the collar, the higher the torque and the
larger the fastener which can be driven. To
lock the clutch for drilling operations, move
to the drill bit position.
NOTE: When using the Drill/Driver for
drilling holes, be sure that the Torque
Adjusting Collar is set so the figure of the
drill is aligned with the arrow on the top
of the tool. Failure to do this will allow the
clutch to slip while attempting to drill
Dual Range Gearing (Fig. 5)
The dual range feature of your Driver/Drill allows you to shift gears for
greater versatility.
To select the low speed, high torque setting, turn the tool off and
permit to stop. Slide the gear shifter (D) forward (towards the chuck)
(position 1), as shown. To select the high speed, low torque setting,
turn the tool off and permit to stop. Slide the gear shifter back (away
from chuck, position 2).
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. 6)
Your tool features a keyless chuck with one rotating sleeve for one-
handed operation of the chuck. To insert a drill bit or other accessory,
follow these steps.
FIG. 5
1. Lock the trigger in the OFF
position.
2. Grasp the black sleeve of
the chuck with one hand
and use the other hand to
secure the tool. Rotate the
C
sleeve counterclockwise far
enough to accept the desired
accessory.
D
3. Insert the accessory about 3/4"
(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.
