REV 05/06

Working with the Rechargeable Battery

Charging the Battery:

1.

Batteries are normally shipped with low or no charge to prevent potential problems during shipment. Before use, you must charge your new Battery.

Initial charge time is approximately 1 hour. Subsequent recharge time is approximately 1 hour.

2.

Plug the battery charger into a 120 VAC, 60 Hz power outlet.

3.

Insert the Battery into the charger by aligning the rib on the Battery with the groove in the charger. Press the Battery into place. The Red LED will illuminate indicating that a Battery is charging.

4.

NOTE:

During recharging, the Battery will become slightly warm to the touch.

This is normal and not a cause for concern. Do not keep the Battery or charger in an environment of extreme heat or cold. They will work best at room temperature.

5.

The Red LED will remain on for approximately 1 hour while the Battery charges. When the Battery is fully charged the charger will stop charging, the

Red LED will go out, and the Green LED will illuminate indicating that the

Battery is fully charged.

6.

When the Battery 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 in the charger indefinitely.

Installing the Battery

1.

Slide the Battery into the base of the handle.

CAUTION:

Do not press the battery into the handle if it is not properly aligned, as this may damage the body of the tool, and will not secure the battery.

2.

Be sure the Battery is properly installed before using the tool.

Using the battery locks and Removing the Battery

1.

After placing the Battery in the tool, battery locks on the side of the Battery engage to prevent the battery from coming out accidentally.

2.

To remove the Battery, depress the battery locks and remove the Battery by pulling straight out.

Special Drive System (SDS)

SDS bits use a cylindrical shank, with indents held by the chuck. To install a bit, pull the Chuck back, insert the bit, then press the chuck forward to lock the bit in place. To remove the bit, pull the Chuck back, pull the bit straight out, and release the Chuck.

The SDS system has the advantage of a spring-loaded chuck, so that bits can be chucked with a simple and quick hand action. Further, the bit and chuck are uniquely suited to hammer drilling in stone and concrete. While the drill bit is held solidly in the chuck, it can slide forward and back like a piston. The hammer of the drill acts to accelerate only the drill bit itself, and not the large mass of the chuck.

That makes hammer drilling with an SDS-plus drill bit much more productive than with other types of bits. SDS bits are most often used for masonry drilling, for which hammer drilling action is most helpful.

SDS bits use sliding keyways that open to the end of the bit, which mate with keys in the chuck. There are additional indents on the bit that are grasped by the chuck to prevent the drill bit falling out. The hammer of the drill hits the flat end of the bit.

NOTE:

To allow the bit to freely slide in the chuck, the shank of the bit must be lubricated with grease.

SDS is available in three sizes, SDS,

SDS-plus, and SDS-max. SDS-plus is the most common type, with masonry drills from 5 mm diameter to 30 mm diameter ordinarily available. The shortest SDS-plus masonry drill bits

SDS-plus chuck operation are about 110 mm overall length, and the longest 1000 mm. If extra long bits are used, a shorter bit must be used first to start the hole.

CAUTION: Use only SDS-Plus bits with this tool.

Operation

For use as a Hammer Drill:

CAUTION:

Use only impact grade SDS-Plus bits, designed for SDS-Plus hammer drills. Standard bits will not be properly held by this Chuck, and may break under the force created by this tool. SDS-Plus 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 Auxiliary Handle, slide the Auxiliary Handle Assembly (32) over the

Front Housing (24). Tighten the screw in the Handle Assemble to lock in place.

Adjust the length of the

Depth Gauge Rod to stop the drilling process when the correct hole depth is reached. Tighten the Depth

Gauge Rod in place by tightening the screw in the

Auxiliary Handle Assembly.

Handle Assembly screw

2.

This tool has three settings,

Drill Only, Hammer Only and Hammer Drill. Select the proper setting for the work you will do. Be sure the tool has come to a

The Hammer Drill with

Auxiliary Handle Assembly complete stop before moving the selector to another setting. Move the

Function Selector to the Hammer Drill setting. Please see picture on page 9 for reference. This setting will allow the drill to hammer as well as turn.

3.

Press the Forward-Reverse Switch (61) to the right for forward drilling, press it to the left for reverse drilling.

4.

The speed of the tool is controlled by squeezing the Trigger (60). Progressively increase or decrease pressure on the Trigger to make the tool operate faster or slower.

5.

The Hammer Drill is best suited for drilling into hard materials such as concrete or masonry. Select an appropriate size and type SDS-Plus hammer drill bit (not included). Insert it onto the Chuck and tighten securely. See instructions on page 7 for inserting SDS-Plus drill bits.

Warning:

Always wear ANSI approved safety glasses and full face shield when hammer drilling.

Caution:

Always check around and behind the area being drilled to prevent drilling into wires, pipes or causing other unintentional property damage.

Always use 2 hands when using this tool.

6.

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.

7.

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 Selector Switch to the Drill setting. Please see picture below for reference. This setting will allow the drill to turn but not hammer.

2.

Select and install an appropriate drill bit. Follow the instructions on page 7 for installing an SDS-plus drill bit.

3.

Start the drill by squeezing the trigger to be sure that the drill bit is properly centered in the Chuck.

Always use 2 hands when using this tool.

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, move the Forward-

Reverse Switch from right to left.

Then squeeze the trigger, the drill will operate in reverse. As needed, stop the operation of the tool, and press the Forward-Reverse Switch from left to right to reset the drill in forward rotation position.

CAUTION:

Do not press the Forward-Reverse

Switch while the tool is operating.

This might damage the tool.

For Use as a Hammer:

1.

Move the Selector Switch to the Hammer setting. Position the bit on the work material where desired. Squeeze the Trigger to make the tool operate. When finished, release the Trigger to stop the tool.

NOTE:

Always wear ANSI approved glasses and full face shield when hammering. Keep hands and fingers away from the tool bit area to prevent injury.

Troubleshooting

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 Pack will not hold a charge as long as older ones. Completely deplete and recharge Battery Pack several times to extend its charge life.

Drill operates as expected, but hole is not drilled effectively:

1.

Sharpen or replace the drill bit. Or select a drill bit more appropriate to the job.

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.

5.

Always dispose of used batteries properly. Contact your local hazardous waste authority for proper disposal guidelines.
