Variable Speed Trigger Switch (Fig. 2)
To turn the tool on, squeeze the trigger switch (A). To turn the tool
off, release the trigger switch. Your tool is equipped with a brake. The
chuck will stop as soon as the trigger switch is fully released.
NOTE: Continuous use in variable speed range is not recommended.
It may damage the switch and should be avoided.
Forward/Reverse Control Button (Fig. 2)
A forward/reverse control button (B) determines the rotational
direction of the tool and also serves as a lock-off button.
To select forward rotation, release the trigger switch and depress the
forward/reverse control button on the right side of the tool.
To select reverse rotation, 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. Circling the
collar (C) are numbers and a drill bit 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.
