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. 2)
Your tool has an adjustable torque screwdriver mechanism for
driving and removing a wide array of fastener shapes and sizes and
in some models, a hammer mechanism for drilling into masonry.
Circling the collar (C) are numbers, a drill bit symbol, and in some
models, a hammer symbol. 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.
Dual Range Gearing (Fig. 2)
The dual range feature of your drill/driver allows you to shift gears
for greater versatility.
1. To select speed 1 (high torque setting), turn the tool off and
permit it to stop. Slide the gear shifter (D) forward (towards the
chuck).
2. To select speed 2 (low torque setting), turn the tool off and
permit it to stop. Slide the gear shifter back (away from the
chuck).
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
are having trouble changing gears, make sure that the dual range
gear shifter is either completely pushed forward or completely
pushed back.
Worklight (Fig. 2)
There is a worklight (E) located just above the trigger switch (A).
The worklight is activated when the trigger switch is depressed,
and will automatically turn off 20 seconds after the trigger switch
is released. If the trigger switch remains depressed, the worklight
will remain on.
NOTE: The worklight is for lighting the immediate work surface and
is not intended to be used as a flashlight.
Keyless Single Sleeve Chuck (Fig. 3–5)
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 and disconnect tool from power
source 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.
Your tool features a keyless chuck (F) with one rotating sleeve for
one-handed operation of the chuck. To insert a drill bit or other
accessory, follow these steps.
1. Turn tool off and disconnect tool from power source.
2. Grasp the black sleeve of the chuck with one hand 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 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.
Be sure to tighten chuck with one hand on the chuck sleeve and
one hand holding the tool for maximum tightness.
To release the accessory, repeat steps 1 and 2 above.
