Operation - DeWalt DC927-XE Instruction Manual

2. Rotate the mode control collar (C) so the screw symbol is aligned with the arrow.
3. Set the torque adjustment collar (D) to the appropriate number setting for the
torque desired.
NOTE: The torque adjustment collar may be set on any number and change
between screwdriving and drilling modes using the mode control collar.
DRILLING (FIG. 3)
CAUTION: When the mode collar is in the drill/hammerdrill mode, the drill will not
clutch out regardless of the position of the torque adjustment collar (D).
Rotate the mode control collar (C) so the drill symbol is aligned with the arrow.
NOTE: The torque adjustment collar (D) may be set on any number.
HAMMERDRILLING (FIG. 4)
Rotate the mode control collar (C) so the hammer symbol is aligned with the arrow.
Torque Adjustment Collar (Fig. 2)
Your tool has an adjustable torque screwdriver mechanism for driving and removing
a wide array of fastener shapes and sizes and a hammer mechanism for drilling into
masonry. Circling the torque adjustment collar (D) are numbers. These numbers are
used to set the clutch to deliver a torque range. The higher the number on the collar,
the higher the torque and the larger the fastener which can be driven. To select any of
the numbers, rotate until the desired number aligns with the arrow.
Three-Speed Gearing (Fig. 2)
The three-speed feature of your tool allows you to shift gears for greater versatility. To
select speed 1 (highest torque setting), turn the tool off and permit it to stop. Slide the
gear shifter (E) all the way to the left. Speed 2 (middle torque and speed setting) is in
the middle position. Speed 3 (highest speed setting) is to the right.
NOTE: Do not change gears when the tool is running. Always allow the drill to come
to a complete stop before changing gears. If you have trouble changing gears, make
sure that the gear shifter is engaged in one of the three speed settings.
Self-Tightening Chuck Operation (Fig. 5–7)
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.
WARNING: Always ensure the bit is secure before starting the tool. A loose bit
may eject from tool causing possible personal injury.

TO INSERT A DRILL BIT OR OTHER ACCESSORY
1. Lock the trigger in the OFF position.
2. Grasp the chuck sleeve (F) with one hand and use the other hand to secure the
tool as shown in Figure 5. Rotate the sleeve counterclockwise (viewed from the
front) far enough to accept the desired accessory.
3. Insert the bit or other accessory about 19 mm (3/4") into the chuck, as shown
in Figure 6. Grasp the chuck sleeve securely and rotate the sleeve clockwise
(viewed from the front) with one hand while using the other hand to secure the
tool. Rotate the sleeve clockwise until sleeve cannot be rotated any further, as
demonstrated in Figure 7. As the drill is being operated in the forward position,
the chuck will continually self-tighten the jaws of the chuck onto the bit to
maximize the bit gripping strength.
To release the accessory, repeat Step 2.
