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.

4. When not in use, remove the Battery Pack and store both tool and Battery

Packs in its case in a dry, secure location.
