Selecting Speed
The speed selector is on top of the motor housing.
Allow the tool to come to a complete stop before
changing speeds. See “Applications” for recom
-
mended speeds under various conditions.
1. For
Low
speed, push the
speed selector to display
“1”.
2. For
High
speed, push the
speed selector to display
“2”.
Using the Control Switch
The control switch may be set to three positions:
forward, reverse and lock. Due to a lockout mecha
-
nism, the control switch can only be adjusted when
the ON/OFF switch is not pressed. Always allow the
motor to come to a complete stop before using the
control switch.

fore use.
2. For
reverse
(counter-
clockwise) rotation, push in the control switch
from the left side of the tool.
Check direction of
rotation before use.
3. To
lock
the trigger,
push the control switch to the
center position. The trigger will not work while the
control switch is in the center locked position.
Always remove the battery pack before performing
maintenance or changing accessories. Always
lock the trigger or remove the battery pack before
storing the tool and any time the tool is not in use.
Starting, Stopping and Controlling Speed
1. To
start
the tool, grasp the handle firmly and pull
the trigger.
NOTE:
An LED is turned on when the trigger is pulled.
2. To
vary
the speed, increase or decrease the pres-
sure on the trigger. The further the trigger is pulled,
the greater the speed.
3. To
stop
the tool, release the trigger. Make sure the bit
comes to a complete stop before laying the tool down.
Battery Pack Protection
To protect the battery from damage and extend its
life, the tool’s intelligent circuit monitors current draw,
temperature, and voltage drops.
In extremely high torque, binding, stalling, and short
circuit situations that cause high current draw, the
fuel gauge will flash, and then the tool will turn OFF.
To reset, release the trigger.
Under extreme circumstances, the internal tem-
perature of the battery could become too high. If this
happens, the fuel gauge will flash and the battery
pack will shut off. Let the battery pack cool and then
continue work.
APPLICATIONS
WARNING
To reduce the risk of electric shock,
check work area for hidden pipes
and wires before drilling or driving screws.
Drilling in Wood, Composition Materials
and Plastic
When drilling in wood, composition materials and
plastic, select the
drill-only operating mode.
Start the drill slowly, gradually increasing speed as
you drill. When drilling into wood, use wood augers
or twist drill bits. Always use sharp bits. When using
twist drill bits, pull the bit out of the hole frequently to
clear chips from the bit flutes. To reduce the chance of
splintering, back work with a piece of scrap wood. Se
-
lect low speeds for plastics with a low melting point.
Drilling in Metal
When drilling in metal, select the drill-only oper-
ating mode.
Use high speed steel twist drills or hole
saws. Use a center punch to start the hole. Lubricate
drill bits with cutting oil when drilling in iron or steel.
Use a coolant when drilling in nonferrous metals such
as copper, brass or aluminum. Back the material
to prevent binding and distortion on breakthrough.
Drilling in Masonry
When drilling in masonry, select the
hammer drill
operating mode. Use high speed carbide-tipped bits.
Drilling soft masonry materials such as cinder block
requires little pressure. Hard materials like concrete
require more pressure. A smooth, even flow of dust
indicates the proper drilling rate. Do not let the bit
spin in the hole without cutting. Do not use water to
settle dust or to cool bit. Both actions will damage
the carbide.
Driving Screws and Nut Running
Drill a pilot hole when driving screws into thick or hard
materials.
Set the torque selector collar to the proper
position and set the speed to low. Use the proper
style and size screwdriver bit for the type of screw
you are using. With the screwdriver bit in the screw,
place the tip of the screw on the workpiece and apply
firm pressure before pulling the trigger. Screws can
be removed by reversing the motor.
Overloading
Continuous overloading may cause permanent damage
to tool or battery pack.
