Charger Diagnostics
This charger is designed to detect certain problems that can arise with the battery packs or the
charger. Problems are indicated by the three red lights flashing together in different patterns.
PROBLEM POWERLINE
When the charger is used with some portable power sources such as generators or sources that
convert DC to AC, the charger may temporarily suspend operation. The three red lights will flash
together with two fast blinks followed by a pause. This indicates that the power souce is out
of limits.
BAD BATTERY
The charger can detect a weak or damaged battery. The three red lights will flash together with
rapid blinking. The battery will no longer charge and should be returned to a service center or a
collection site for recycling.
BAD CHARGER
The charger will detect if it is not functioning properly. The three red lights will flash together with
one fast blink followed by a long blink. The charger will no longer work and should be returned
to an authorized service center or replaced.
LEAVING THE BATTERY IN THE CHARGER
The charger and battery pack can be left connected with the red lights glowing indefinitely. The
charger will keep the battery pack fresh and fully charged. This charger features an automatic tune-
up mode which equals or balances the individual cells in the battery pack to allow it to function
at peak capacity. Battery packs should be tuned up weekly or whenever the battery no longer
delivers the same amount of work. To use the automatic tune-up mode, place the battery pack in
the charger and leave it for at least 8 hours.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery pack is charged when the air
temperature is between 65 °F and 75 °F (18 °–24 °C). DO NOT charge the battery pack in an
air temperature below +40 °F (+4.5 °C), or above +105 °F (+40.5 °C). This is important and will
prevent serious damage to the battery pack.
2. The charger and battery pack may become warm to touch while charging. This is a normal
condition, and does not indicate a problem. To facilitate the cooling of the battery pack after
use, avoid placing the charger or battery pack in a warm environment such as in a metal shed,
or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check operation of receptacle by plugging in a lamp or other appliance;
b. Check to see if receptacle is connected to a light switch which turns power off when you turn
out the lights;
c. Move charger and battery pack to a location where the surrounding air temperature is
approximately 65 °F–75 °F (18 °– 24 °C);
d. If charging problems persist, take the tool, battery pack and charger to your local service
center.
4. The battery pack should be recharged when it fails to produce sufficient power on jobs which
were easily done previously. DO NOT CONTINUE to use under these conditions. Follow the
charging procedure. You may also charge a partially used pack whenever you desire with no
adverse affect on the battery pack.
5. Under certain conditions, with the charger plugged into the power supply, the exposed
charging contacts inside the charger can be shorted by foreign material. Foreign materials of a
conductive nature such as, but not limited to, grinding dust, metal chips, steel wool, aluminum
foil, or any buildup of metallic particles should be kept away from charger cavities. Always
unplug the charger from the power supply when there is no battery pack in the cavity. Unplug
charger before attempting to clean.
6. Do not freeze or immerse charger in water or any other liquid.
WARNING: Shock hazard. Don't allow any liquid to get inside charger. Electric shock may result.
WARNING: Burn hazard. Never attempt to open the battery pack for any reason. If the plastic
housing of the battery pack breaks or cracks, return to a service center for recycling.
Storage Recommendations
1. The best storage place is one that is cool and dry away from direct sunlight and excess heat
or cold.
2. For long storage, it is recommended to store a fully charged battery pack in a cool dry place
out of the charger for optimal results.
NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will
need to be recharged before use.

Your tool is equipped with a brake. The chuck will stop as soon as the trigger switch is fully released.
NOTE: Continuous use in variable speed range is not recommended. It may damage the switch
and should be avoided.
Forward/Reverse Control Button (Fig. 1)
A forward/reverse control button (B) determines the direction the tool will spin and also serves as
a lock-off button.
To select forward rotation, release the trigger switch and depress the for ward/re verse control button
on the right side of the tool.
To select reverse, depress the forward/reverse control button on the left side of the tool.
The center position of the control button locks the tool in the OFF position. When changing the
position of the control button, be sure the trigger is released.
NOTE: The first time the tool is run after changing the direction of rotation, you may hear a click on
start up. This is normal and does not indicate a problem.
Mode Control Collar
Your drill is equipped with a separate mode control collar (Fig. 1, C) to switch between drilling,
screwdriving and hammerdrilling mode.
SCREWDRIVING (FIG. 2)
1. Select the desired speed/torque range using the three-speed gear shifter (E) on the top of tool
to match the speed and torque to the planned application. To set the torque level to the proper
setting on the clutch collar, initially set the clutch collar at a lower setting to ensure the fastener
to be set to your specification.
NOTE: Use the lowest torque setting required to seat the fastener at the desired depth. The
lower the number, the lower the torque output.
2. Rotate the mode control collar (C) so the screw symbol is aligned with the arrow.
3. Set the torque adjustment collar (D) to the appropriate number setting for the torque desired.
NOTE: The torque adjustment collar may be set on any number and change between
screwdriving and drilling modes using the mode control collar.
DRILLING (FIG. 3)
CAUTION: When the mode collar is in the drill/hammerdrill mode, the drill will not clutch out
regardless of the position of the torque adjustment collar (D).
Rotate the mode control collar (C) so the drill symbol is aligned with the arrow.
NOTE: The torque adjustment collar (D) may be set on any number.
HAMMERDRILLING (FIG. 4)
Rotate the mode control collar (C) so the hammer symbol is aligned with the arrow.
Torque Adjustment Collar (Fig. 2)
Your tool has an adjustable torque screwdriver mechanism for driving and removing a wide array of
fastener shapes and sizes and a hammer mechanism for drilling into masonry. Circling the torque
adjustment collar (D) are numbers. These numbers are used to set the clutch to deliver a torque
range. The higher the number on the collar, the higher the torque and the larger the fastener which
can be driven. To select any of the numbers, rotate until the desired number aligns with the arrow.
Three-Speed Gearing (Fig. 2)
The three-speed feature of your tool allows you to shift gears for greater versatility. To select speed
1 (highest torque setting), turn the tool off and permit it to stop. Slide the gear shifter (E) all the way
to the left. Speed 2 (middle torque and speed setting) is in the middle position. Speed 3 (highest
speed setting) is to the right.
NOTE: Do not change gears when the tool is running. Always allow the drill to come to a complete
stop before changing gears. If you have trouble changing gears, make sure that the gear shifter is
engaged in one of the three speed settings.

TO INSERT A DRILL BIT OR OTHER ACCESSORY
Your tool features a keyless chuck with one rotating sleeve for one-handed operation of the chuck.
To insert a drill bit or other accessory, follow these steps.
1. Turn tool off and disconnect tool from power source.
2. Grasp the black sleeve of the chuck (F) with one hand and use the other hand to secure the tool
as shown in Figure 5. Rotate the sleeve counterclockwise (as viewed from the front) far enough
to accept the desired accessory.
3. Insert the accessory about 3/4" (19 mm) into the chuck and tighten securely by rotating the
chuck sleeve clockwise with one hand while holding the tool with the other hand. Continue to
rotate the chuck sleeve until several ratchet clicks are heard to ensure full gripping power.
Be sure to tighten chuck with one hand on the chuck sleeve and one hand holding the tool for
maximum tightness.
To release the accessory, repeat Steps 1 and 2 above.
OPERATION
WARNING: To reduce the risk of serious personal injury, turn tool off and remove the
battery pack before making any adjustments or removing/installing attachments or
accessories. An accidental start-up can cause injury.
Installing and Removing the Battery Pack (Fig. 8)
NOTE: For best results, make sure your battery pack is fully charged.
CAUTION: Make certain the forward/reverse (lock-off) button (B), as shown in Figure 1, is
engaged to prevent switch actuation before removing or installing battery.
To install the battery pack into the tool handle, align the battery pack with the rails inside the tool's
handle and slide it into the handle until the battery pack is firmly seated in the tool and ensure that
it does not disengage.
To remove the battery pack from the tool, press the release button (G) and firmly pull the battery
pack out of the tool handle. Insert it into the charger as described in the charger section of this
manual.
Side Handle
WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the side handle
properly installed. Failure to do so may result in the side handle slipping during tool operation and
subsequent loss of control. Hold tool with both hands to maximize control.
Side handle clamps to the front of the gear case as shown and may be rotated to
permit right- or left-hand use. Side handle must be tightened sufficiently to
resist the twisting action of the tool if the accessory binds or stalls. Be sure
to grip the side handle at the far end to control the tool during a stall.
If model is not equipped with side handle, grip drill with one hand on the
handle and one hand on the battery pack.
Screwdriver Operation (Fig. 2)
Select the desired speed/torque range using the three-speed gear shifter (E) on the top of tool
to match the speed and torque to the planned operation. Insert the desired fastener accessory
into the chuck as you would any drill bit. Set the torque adjustment collar (D) to the desired
setting. Make a few practice runs in scrap or unseen areas to determine the proper position of the
clutch collar.
Drill Operation (Fig. 3)
1. Select the desired speed/torque range using the gear shifter (E) to match the speed and torque
to the planned operation.
2. For WOOD, use twist bits, spade bits, power auger bits or hole saws. For METAL, use high-
speed steel twist drill bits or hole saws. Use a cutting lubricant when drilling metals. The
exceptions are cast iron and brass which should be drilled dry.
3. Always apply pressure in a straight line with the bit. Use enough pressure to keep the drill bit
biting, but do not push hard enough to stall the motor or deflect the bit.
4. Hold tool firmly with both hands to control the twisting action of the drill.
5. IF DRILL STALLS, it is usually because it is being overloaded. RELEASE TRIGGER
IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT CLICK
TRIGGER OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL – THIS CAN
DAMAGE THE DRILL.
6. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
Hammerdrill Operation (Fig. 4)
1. When drilling, use just enough force on the hammer to keep it from bouncing excessively or
"rising" off the bit. Too much force will cause slower drilling speeds, overheating, and a lower
drilling rate.
2. Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit
when drilling as this will cause clogging of the bit flutes and a slower drilling speed.
3. When drilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of the
hole with the tool still running to help clear debris from the hole.
4. For MASONRY, use carbide-tipped bits or masonry bits. A smooth, even flow of dust indicates
the proper drilling rate.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury, turn tool off and remove the
battery pack before making any adjustments or removing/installing attachments or
accessories. An accidental start-up can cause injury.
Cleaning
WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week. To
minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when performing
this.
WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts
of the tool. These chemicals may weaken the plastic materials used in these parts. Use a cloth
dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse
any part of the tool into a liquid.
