Charge Indicators
This charger is designed to detect certain problems that can arise. Problems are indicated by the red
light flashing at a fast rate. If this occurs, re-insert the battery pack into the charger. If the problem
persists, try a different battery pack to determine if the charger is working properly. If the new pack
charges correctly, then the original pack is defective and should be returned to a service center or
other collection site for recycling. If the new battery pack elicits the same trouble indication as the
original, have the charger and the battery pack tested at an authorized service center.
HOT/COLD DELAY
This charger has a hot/cold delay feature: when the charger detects a battery that is hot, it
automatically starts a delay, suspending charging until the battery has cooled. After the battery
has cooled, the charger automatically switches to the pack charging mode. This feature ensures
maximum battery life. The red light flashes long, then short while in the hot/cold delay mode.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the charge indicator showing Pack
Charged.
WEAK BATTERY PACKS: Weak batteries will continue to function but should not be expected to
perform as much work.
FAULTY BATTERY PACKS: This charger will not charge a faulty battery pack. The charger will
indicate faulty battery pack by refusing to light or by displaying problem pack or charger.
NOTE: This could also mean a problem with a charger.
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 the 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. A cold battery pack will charge at about half the rate of a warm battery pack. The battery
pack will charge at that slower rate throughout the entire charging cycle and will not return to
maximum charge rate even if the battery pack warms.
4. 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 the 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.
5. 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 effect on the battery pack.
6. 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 the charger before attempting to clean.
7. Do not freeze or immerse the charger in water or any other liquid.
WARNING: Shock hazard. Don't allow any liquid to get inside the charger. Electric shock may
result.
WARNING: Burn hazard. Do not submerge the battery pack in any liquid or allow any liquid to
enter the battery pack. 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.

OPERATION
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect
tool from power source before making any adjustments or removing/installing
attachments or accessories.
Installing and Removing the Battery Pack (Fig. 2)
NOTE: For best results, make sure your battery pack is fully charged.
To install the battery pack (K) 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 (J) 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.
Drilling (Fig. 7)
NOTICE: If drilling thin material, use a wood "back-up" block to prevent damage to the material.
1. Select the desired speed/torque range using the gear shifter to match the speed and torque to
the planned operation. Turn the collar (C) to the drill symbol.
2. Use sharp drill bits only. For MASONRY, such as brick, cement, cinder block, etc., use carbide-
tipped bits rated for percussion drilling.
3. Always apply pressure in a straight line with the bit. Use enough pressure to keep drill 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. If model is not equipped
with side handle, grip drill with one hand on the handle and one hand on the battery pack.
WARNING: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip the
drill firmly to control the twisting action and avoid injury.
5. IF DRILL STALLS, it is usually because it is being overloaded or improperly used. RELEASE
TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO
NOT DEPRESS TRIGGER ON AND OFF IN AN ATTEMPT TO START A STALLED DRILL
— THIS CAN DAMAGE THE DRILL.
6. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit
through the last fractional part of the hole.
7 . Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
Screwdriving (Fig. 8)
1. Select the desired speed/torque range using the gear shifter to match the speed and torque to
the planned operation.
2. Turn the torque adjustment collar (C) to the desired position.
NOTE: Use the lowest torque setting required to seat the fastener at the desired depth. The
lower the number, the lower the torque output.
3. Insert the desired fastener accessory into the chuck as you would any drill bit.
4. Make some practice runs in scrap or on unseen areas of the workpiece to determine the proper
position of the torque adjustment collar.
5. Always start with lower torque settings, then advance to higher torque settings to avoid
damage to the workpiece or fastener.
Hammerdrilling (Fig. 9)
1. Select the desired speed/torque range using the gear shifter to match the speed and torque to
the planned operation. Turn the collar (C) to the hammerdrill symbol.
IMPORTANT: Use carbide-tipped or masonry bits rated for percussion drilling only.
2. Drill with 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.
3. Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit
when drillling as this will cause clogging of the bit flutes and a slower drilling speed.
4. When drilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of the
hole with tool still running to help clear debris from the hole.
NOTE: A smooth, even flow of dust from the hole indicates proper drilling rate.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect
tool from power source before making any adjustments or removing/installing
attachments or accessories.
Cleaning
WARNING: Blow dirt and dust out of all air vents with dry air at least once a week. Wear proper
ANSI Z87.1 (CAN/CSA Z94.3) eye protection and proper NIOSH/OSHA/MSHA respiratory
