ENGLISH
WARNING: To reduce the risk of serious
personal injury, ALWAYS hold securely in
anticipation of a sudden reaction.
Proper hand position requires one hand on the main handle (i).
Trigger Switch (Fig. A)
To turn the tool on, squeeze the trigger switch (1). To turn the
tool off, release the trigger switch. Your tool is equipped with
a brake. The chuck will stop when the trigger switch is fully
released.
The variable speed switch enables you to select the best speed
for a particular application. The further you squeeze the trigger,
the faster the tool will operate. For maximum tool life, use
variable speed only for starting holes or fasteners
NOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should be
avoided.
Forward/Reverse Control Button
(Fig. A)
A forward/reverse control button (2) determines the 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, 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.
LED Worklight (Fig. A)
There is a LED worklight (8) located under the torque
adjustment collar (3). The worklight will be activated when the
trigger switch is squeezed.
NOTE: The worklight is for lighting the immediate work surface
and is not intended to be used as a flashlight.
Torque Adjustment Collar (Fig. A)
The torque adjustment collar (3) is clearly marked with numbers
and a drill bit symbol.The collar should be rotated until the desired
setting is located at the top of the tool. Locators are provided in the
collar to eliminate the guess work when selecting fastening torque.
The higher the number on the collar, the higher the torque and
the larger the fastener which can be driven. To lock the clutch for
drilling operations, move to the drill bit position.
NOTE: When using the drill/driver for drilling holes, be sure that
the torque adjusting collar is set so the figure of the drill is aligned
with the center line on the top ofthe tool. Failure to do this will
allow the clutch to slip while attempting to drill.

Gear Shifter (Fig. A, D)
The dual range feature of your driver/drill allows you to shift gears
for greater versatility.
To select the low speed, high torque setting, turn the tool off and
permit to stop. Slide the gear shifter (4) forward (towards the
chuck). To select the high speed, low torque setting, turn the tool
off and permit to stop. Slide the gear shifter back (away from
chuck).
NOTE: Do not change gears when the tool is running. If you
are having trouble changing gears, make sure that the dual range
gear shifter is either completely pushed forward or completely
pushed back.
Keyless Chuck (Fig. E)
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. Lock the trigger in the OFF position as previously described.
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.
To release the accessory, repeat step 2 above.
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 when changing acces sories.
Be sure to tighten chuck with one hand on the chuck sleeve and
one hand holding the tool for maximum tightness.
Chuck removal (FIG. F)
Turn the adjustment collar to the "drill" position and gear shifter
to position 1 (low speed). Tighten the chuck around the shorter
end of a hex key (not supplied) of 6.35 mm (1/4") or greater
size. Using a wooden mallet or similar object, strike the longer
end in the clockwise direction, as shown. This will loosen the
screw inside the chuck.
Open chuck jaws fully, insert screwdriver (or Torx tool if required)
into front of chuck between jaws to engage screw head.
Remove screw by turning clockwise (left-hand-thread). Place
hex key in chuck and tighten, as shown in Figure F. Using
a wooden mallet or similar object, strike key sharply in the
counterclockwise direction. This will loosen the chuck so that it
can be unscrewed by hand.
