Torque Adjustment Collar/Electronic Clutch
(Fig.A)
Your tool has an electronic adjustable torque screwdriver
mechanism for driving and removing a wide array of fasteners.
Circling the torque adjustment collar
5
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.

WARNING: When the torque adjustment collar is in the
drill or hammerdrill positions, the drill will not clutch. The
drill may stall if overloaded, causing a suddentwist.
Three-Speed Gearing (Fig.A)
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
8
all the way forward. Speed 2 (middle torque and speed setting)
is in the middle position. Speed 3 (highest speed setting) is to
therear.
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.
If the speed shifter becomes stuck or is difficult to select the
desired gear, pull the variable speed trigger switch
3
to rotate
the motor, then select thegear.
LED Worklight (Fig.E)
The LED worklight

and its worklight switch
10
are located on
the foot of the tool. The worklight is activated when the trigger
switch is depressed. The low, medium, and spotlight 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 and medium settings, the beam will automatically
turn off 20 seconds after the trigger switch isreleased.
Spotlight Mode
The high setting 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.
