• Do not incinerate the battery pack even if it is severely damaged or is completely
worn out. The battery pack can explode in a fire. Toxic fumes and materials are created
when lithium ion battery packs are burned.
• Do not charge or use battery in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust. Inserting or removing the battery from the charger may ignite the dust
or fumes.
• If battery contents come into contact with the skin, immediately wash area with mild soap
and water. If battery liquid gets into the eye, rinse water over the open eye for 15 minutes or
until irritation ceases. If medical attention is needed, the battery electrolyte is composed of a
mixture of liquid organic carbonates and lithium salts.
• Contents of opened battery cells may cause respiratory irritation. Provide fresh air. If symp-
toms persists, seek medical attention
WARNING: Burn hazard. Battery liquid may be flammable if exposed to spark or flame.
• Charge the battery packs only in D
• DO NOT splash or immerse in water or other liquids.
• Do not store or use the tool and battery pack in locations where the temperature may
reach or exceed 105°F (40˚) (such as outside sheds or metal buildings in summer).
WARNING: Never attempt to open the battery pack for any reason. If battery pack case is
cracked or damaged, do not insert into charger. Do not crush, drop or damage battery pack.
Do not use a battery pack or charger that has received a sharp blow, been dropped, run over
or damaged in any way (i.e., pierced with a nail, hit with a hammer, stepped on). Damaged
battery packs should be returned to service center for recycling.
WARNING: Fire hazard. Do not store or carry battery so that metal objects can contact
exposed battery terminals. For example, do not place battery in aprons, pockets, tool boxes,
product kit boxes, drawers, etc., with loose nails, screws, keys, etc. Transporting batteries
can possibly cause fires if the battery terminals inadvertently come in contact with
conductive materials such as keys, coins, hand tools and the like. The US Department of
Transportation Hazardous Material Regulations (HMR) actually prohibit transporting batteries in
commerce or on airplanes (i.e., packed in suitcases and carry-on luggage) UNLESS they are
properly protected from short circuits. So when transporting individual batteries, make sure that
the battery terminals are protected and well insulated from materials that could contact them
and cause a short circuit.

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 current at 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 ser-
vice 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. Foreign materials of a conductive nature such as, but not limited to, 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. Do not allow any liquid to get inside charger.
CAUTION: 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.

SHOCKS
TM
– Active Vibration Control
For best vibration control, hold the tool with one hand on the main handle (E) and the other
hand on the side handle (A). Apply just enough pressure so the hammer is approximately mid-
stroke. The hammer only needs enough pressure to engage the internal active vibration control.
Applying too much pressure will not make the tool drill faster and active vibration control will not
engage.
SDS Chuck (Fig. 4)
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect
tool from battery pack before making any adjustments or removing/installing attachments
or accessories.
CAUTION: Do not use chipping bits in this tool. Using chipping bits may cause the tool to bind-
up and damage to the tool may occur.
To insert bit, insert shank of bit about 3/4" into chuck (J) . Push and rotate bit until it locks in
place. The bit will be securely held.
To release bit, pull the sleeve (K) back and remove the bit.
Drilling
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect
tool from battery pack before making any adjustments or removing/installing attachments
or accessories.
1. Use sharp drill bits only. For MASONRY, such as brick, cement, cinder block, etc., use car-
bide-tipped bits rated for percussion drilling. Be sure the material to be drilled is anchored
or clamped firmly. If drilling thin material, use a wood "back-up" block to prevent damage to
the material.
2. 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.
3. Hold tool firmly with both hands to control the twisting action of the drill.
4. 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 CLICK TRIGGER ON AND OFF IN AN AT TEMPT TO START A STALLED DRILL
— THIS CAN DAMAGE THE DRILL.
5. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
6. Use a slow speed to start the hole and accelerate by squeezing the trigger harder when the
hole is deep enough to drill without the bit skipping out.
DRILLING IN MASONRY
WALT tools
E
When drilling in masonry, use carbide tipped bits rated for masonry drilling. Be certain that the
bit is sharp. Ensure that the hammer mode is selected. Use a constant and firm force on the tool
to drill most effectively. 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 disconnect
tool from battery pack before making any adjustments or removing/installing attachments
or accessories.
Cleaning
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.
CHARGER CLEANING INSTRUCTIONS
WARNING: Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt
and grease may be removed from the exterior of the charger using a cloth or soft non-metallic
brush. Do not use water or any cleaning solutions.
Lubrication
Your tool was properly lubricated before leaving the factory. In from two to six months, depend-
ing upon use, take or send your tool to an authorized service center for a complete cleaning,
inspection and lubrication. Tools used constantly on production jobs will need relubrication more
often. Also, tools "out of service" for long periods should be relubricated before being put back
to work.
