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

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.
1. Turn off tool and disconnect tool from power
source.
2. Grasp the black sleeve of the chuck (D) with
one hand and use the other hand to secure the
tool as shown in Figure 6. Rotate the sleeve
counterclockwise (as viewed from the front) far
enough to accept the desired accessory.
3. Insert the accessory about 19 mm into the
chuck (Fig. 7). Tighten securely by rotating the
chuck sleeve clockwise with one hand while
holding the tool with the other hand (Fig. 8).
Continue to rotate the chuck sleeve until several
ratchet clicks are heard to ensure full gripping
power.
To release the accessory, repeat Steps 1 and 2
above.
Be sure to tighten chuck with one hand on the
chuck sleeve and one hand holding the tool for
maximum tightness.
LED Worklight (Fig. 1)
The LED worklight (C) and its worklight switch (M)
are located on the foot of the tool. The worklight is
activated when the trigger switch is depressed. The
low (N), medium (O) and spotlight (P) modes can be
changed by moving the switch on the foot of the
tool. If the trigger switch remains depressed, the
worklight will remain on in all modes.
When on low (N) and medium (O) settings, the beam
will automatically turn off 20 seconds after the trigger
switch is released.
SPOTLIGHT MODE
The high setting (P) is the spotlight mode. The
spotlight will run for 20 minutes after the trigger
switch is released. Two minutes before the spotlight
will shut off, it will flash twice and then dim. To
avoid the spotlight shutting off, lightly tap the trigger
switch.
WARNING: While using the worklight in
medium or spotlight mode, do not stare
at the light or place the drill in a position
which may cause anyone to stare into
the light. Serious eye injury could result.
CAUTION: When using the tool as a
spotlight, be sure it is secured on a
stable surface where it will not cause a
tripping or falling hazard.
CAUTION: Remove all accessories
from the chuck before using the drill as
a spotlight. Personal injury or property
damage could result.
LOW BATTERY WARNING
When in spotlight mode and the battery is nearing
complete discharge, the spotlight will flash twice
and then dim. After two minutes, the battery will be
completely discharged and the drill will immediately
shut down. At this point, replace with a charged
battery.
WARNING: To reduce the risk of
injury, always have a back-up battery
or secondary lighting available if the
situation warrants it.
