Small screws in softwood.
Medium screws in softwood or small
screws in hardwood.
Large screws in softwoods. Medium
screws in hardwood or large screws in
hardwood with pilot hole.
NOTE: Because the settings shown in the table are
only a guide, use a piece of scrap material to test the
dierent clutch settings before driving screws into
the workpiece.
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.
LOCK - Push to CENTER
ReverseForward
For forward (clockwise) rotation, push in the control
switch from the right side of the tool. Check the
direction of rotation before use.
For reverse (counterclockwise) rotation, push in the
control switch from the left side of the tool. Check
direction of rotation before use.
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
lock the trigger or remove the battery pack before
performing maintenance, changing accessories,
storing the tool and any time the tool is not in use.
WARNING
To reduce the risk of injury, always
hold or brace securely.
Starting, Stopping and Controlling Speed
1. To start the tool, grasp the handles rmly 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.
Drilling
Place the bit on the work surface and apply rm pres-
sure before starting. Too much pressure will slow the
bit and reduce drilling eciency. Too little pressure
will cause the bit to slide over the work area and dull
the point of the bit.
If the tool begins to stall, reduce pressure slightly to
allow the bit to regain speed. If the bit binds, reverse
the motor to free the bit from the workpiece.
APPLICATIONS
WARNING
To reduce the risk of electric shock,
check work area for hidden pipes
and wires before drilling or driving screws.
To reduce the risk of injury in applications that
produce a considerable amount of dust, use
an OSHA compliant dust extraction solution
in accordance with the solution’s operating
instructions.
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 utes. 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 ow 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. Select the driving screws mode. 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 rm pressure
before pulling the trigger. Screws can be removed
by reversing the motor.
Overloading
Continuous overloading may cause permanent dam-
age to tool or battery pack.
