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 (figure 1)
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 (figure 1)
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 (figure 1)
There is a worklight (e) located just above the
trigger switch (a). The worklight is activated when
the trigger switch is depressed. When the trigger is
released the worklight will stay illuminated for up to
20 seconds.
NOTE: The worklight is for lighting the immediate
work surface and is not intended to be used as a
flashlight.
Keyless Single Sleeve Chuck
(figure 7–9)
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 19 mm (3/4") 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.
