Working with the Rechargeable Battery
Charging the Battery Pack:
1. Battery Packs are normally shipped with low or no charge to prevent potential
problems during shipment. Before use, you must charge your new Battery Pack.
Initial charge time is approximately 1-½ hour. Subsequent recharge time is
approximately 1-½ hour. New Battery Packs will not hold a charge as long as
older ones. Completely deplete and recharge Battery Pack several times to
extend its charge life.
2. Plug the battery charger into a 120 VAC, 60 Hz power outlet, the Green LED will
illuminate.
3. Insert the Battery Pack into the charger by aligning the rib on the Battery Pack
with the groove in the charger. Press the Battery Pack into place. The Green
LED will shut off and the Red LED will illuminate indicating that a Battery Pack
is installed in the charger, and that it has started charging.
NOTE: During recharging, the Battery Pack will become slightly warm to the touch.
This is normal and not a cause for concern. Do not keep the Battery Pack or
charger in an environment of extreme heat or cold. They will work best at room
temperature.
4. The red LED will remain on for approximately 1 hour while the Battery Pack
charges. When the Battery Pack is fully charged the Red LED will go out, and
the Green LED will illuminate indicating that the Battery Pack is fully charged.
5. When the Battery Pack is fully charged, remove the charged battery from the
charger, and unplug the charger from its power source. Put the charger away for
safekeeping. Do not leave the Battery Pack in the charger indefinitely.
Installing the Battery Pack
1. Slide the Battery Pack onto the rail of
the body before pressing it into the
handle. CAUTION: Do not press the
battery into the handle if it is not
properly aligned on the rail, as this may
damage the body of the tool, and will
not secure the battery.
2. With the Battery Pack properly
aligned on the rail, press into place
in the handle.

Operation
For use as a Hammer Drill:
CAUTION: Use only impact grade bits, designed for hammer drills. Standard bits may
break under the force created by this tool. Impact grade bits are available from
Harbor Freight Tools.
1. The Auxiliary Handle must be installed for additional stability when Hammer
Drilling. Always use both hands to hold this tool during hammer drill
operation. To install Axillary Handle, loosen the screw on the side of the assembly.
Slide the Auxiliary Handle assembly over the aluminum portion of the tool, as
shown in the photograph. Adjust the length of the Depth Gauge Rod to stop the
drilling process when the correct hole depth is reached.Tighten the assembly in
place by turning the handle
clockwise. The handle may be
installed on either the right or left
side of the tool.
2. Select and install an appropriate drill
bit. Do this by opening the jaws of
the Chuck using the Chuck Key.
Insert the butt end of the drill bit
into the center of the Chuck. Rotate
the Chuck to close the Jaws on the
drill bit. Be sure that the bit is
centered in the Chuck Jaws.
Tighten in place using the Chuck
Key.
3. Move the Torque Selection Ring to
the Hammer Drill setting. Please see picture on page 7 for reference.This setting
will allow the drill to hammer as well as turn.
4. This tool has two Gear Settings, Low and High. Please refer to photo on page 7.
With the Gear Selector moved forward in High position the maximum blows per
minute is 19,200 BPM and rotation is 1,290 RPM. With the selector back in the
Low position, the maximum speed is 5,280 BPM and 360 RPM.
5. The Hammer Drill is best suited for drilling into hard materials such as concrete
or masonry. Select an appropriate size and type hammer drill bit (not included).
Insert it onto the Chuck and tighten securely. Be sure the drill bit is properly
inserted and tight before proceeding.
Warning: Always wear ANSI approved safety glasses and full face shield when
hammer drilling, as removed material will fly uncontrollably, possibly causing
injury. Caution: Always check around and behind the area being drilled to prevent
drilling into wires, pipes or causing other unintentional property damage.

4. Position the drill bit at the place to be drilled and squeeze the Trigger. The tool
is variable speed, and will rotate and hammer faster as the Trigger is
progressively squeezed.
5. When the forward end of the Depth Gauge Rod contacts the work surface, you
know the hole is the desired depth. Release the Trigger to stop the operation
of the tool, and withdraw the bit from the hole.
For Use as a Drill:
1. Move the Torque Selection Ring to the Drill setting. Please see picture on
page 7 for reference.This setting will allow the drill to turn but not hammer.
Move the Gear Selector to High or Low.
2. Select and install an appropriate drill bit. Do this by opening the jaws of the
Chuck using the Chuck Key. Insert the butt end of the drill bit into the center
of the Chuck. Rotate the Chuck to close the Jaws on the drill bit. Be sure that
the bit is centered in the Chuck Jaws. Tighten in place using the Chuck Key.
3. Start the drill by squeezing the trigger to be sure that the drill bit is properly
centered in the Chuck.
4. Position the drill bit at the appropriate point on the workpiece and squeeze the
trigger to start the drill operating. The tool is variable speed, and will rotate
faster as the Trigger is progressively squeezed.
5. When the desired depth has been reached, release the Trigger to stop the
operation of the tool, and withdraw the bit from the hole.
NOTE: This tool is reversible. If
the drill bit does not withdraw
easily from the hole, you may
reverse the rotation to help it
come out. With the tool stopped,
press the REV button from left to
right. Then lightly squeeze the
trigger; the drill will operate in
reverse. As needed, stop the
operation of the tool, and press
the REV button from right to left
to reset the drill in forward
rotation position. CAUTION: Do
not press the REV button while
the tool is operating. This will damage the tool.

For Use as a Screwdriver:
1. Move the Torque Selection Ring to the desired Torque setting, and the Gear
Selector to the desired selection. The Torque Setting will allow the internal
clutch to slip when the desired torque is reached. This will prevent the screw
from being driven too deep into the work material. This also prevents damage
to the tool caused by sudden stops as the screw bottoms out.You should
determine the proper torque setting by drilling several screws into scrap
material before beginning work. A higher number is higher torque.
NOTE: Press the REV button from left to right and then squeeze the trigger to
allow the tool to operate in reverse.
NOTE: Use of a screw holder bit attachment (not included) is recommended to
prevent possible injury to your hand or fingers.
Trouble Shooting
Tool will not operate or operates slowly:
1. Battery Pack may be discharged. Replace Battery Pack with a fresh one, or
recharge the Battery Pack.
2. Too great a load is being placed on the tool. Lighten pressure on workpiece.
Battery Pack loses charge quickly:
1. New Battery Packs will not hold a charge as long as older ones. Completely
deplete and recharge Battery Pack several times to extend its charge life.
Maintenance
1. Keep your tool clean and dry. Wipe dirt and grease from it if it becomes dirty.
2. Do not allow your tool, Battery Packs or Charger to become wet.
3. Do not leave Battery Pack in Charger unattended for long periods of time.
