General Safety Rules – For All Battery Operated Tools
WARNING! Read and understand all instructions. Failure to follow all instructions listed
below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
• Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or
fumes.
• Keep bystanders, children, and visitors away while operating a power tool. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
• Do not abuse the cord. Never use the cord to carry the tool. Keep cord away from
heat, oil, sharp edges or moving parts. Replace damaged cords immediately.
Damaged cords may create a fire.
• A battery operated tool with integral batteries or a separate battery pack must be
recharged only with the specified charger for the battery. A charger that may be suit-
able for one type of battery may create a risk of fire when used with another battery.
• Use battery operated tool only with the specifically designed battery pack. Use of any
other batteries may create a risk of fire.
PERSONAL SAFETY
• Stay alert, watch what you are doing, and use common sense when operating a power
tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication.
A moment of inattention while operating power tools may result in serious personal injury,
• Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your
hair, clothing, and gloves away from moving parts. Loose clothing, jewelry, or long hair
can be caught in moving parts.
• Avoid accidental starting. Be sure switch is in the locked or off position before
inserting battery pack. Carrying tools with your finger on the switch or inserting the battery
pack into a tool with the switch on invites accidents.
• Remove adjusting keys or wrenches before turning the tool on. A wrench or key that is
left attached to a rotating part of the tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enables better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes,
hard hat, or hearing protection must be used for appropriate conditions.
TOOL USE AND CARE
• Use clamps or other practical way to secure and support the workpiece to a stable
platform. Holding the work by hand or against your body is unstable and may lead to loss of
control.
• Do not force tool. Use the correct tool for your application. The correct tool will do the job
better and safer at the rate for which it is designed.
• Do not use tool if switch does not turn it on or off. A tool that cannot be controlled with the
switch is dangerous and must be repaired.
• Disconnect battery pack from tool or place the switch in the locked or off position
before making any adjustments, changing accessories, or storing the tool. Such
preventative safety measures reduce the risk of starting the tool accidentally.
• Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.

WALT TOOL,
E
• When battery pack is not in use, keep it away from other metal objects like: paper clips,
coins, keys, nails, screws, or other small metal objects that can make a connection from
one terminal to another. Shorting the battery terminals together may cause sparks, burns, or
a fire.
• Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools,
with sharp cutting edge are less likely to bind and are easier to control.
• Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the tool's operation. If damaged, have the tool serviced before
using. Many accidents are caused by poorly maintained tools.
• Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may create a risk of injury when used on another
tool.
SERVICE
• Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
• When servicing a tool, use only identical replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk of shock or injury.
Additional Safety Rules
• Hold tool by insulated gripping surfaces when performing an operation where the
cutting tool may contact hidden wiring. Contact with a "live" wire will make exposed metal
parts of the tool "live" and shock the operator.
• CAUTION: When cutting into walls, floors or wherever live electrical wires may be
encountered, DO NOT TOUCH ANY METAL PARTS OF THE TOOL! Hold the tool only by
insulated grasping surfaces to prevent electric shock if you cut into a live wire.
• KEEP HANDS AWAY from cutting area. Never reach underneath the material for any reason.
Hold front of saw by grasping the contoured gripping area. Do not insert fingers or thumb into
the vicinity of the reciprocating blade and blade clamp. Do not stabilize the saw by gripping the
shoe.
• KEEP BLADES SHARP. Dull blades may cause the saw to swerve or stall under pressure.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-
struction activities contains chemicals known to cause cancer, birth defects or other reproduc-
tive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you do this type of work. To
reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to filter out
microscopic particles.

Battery Packs
Your tool uses a 12.0, 14.4 or an 18.0 Volt D
battery packs, be sure to include catalog number and voltage. XR PACK™ Extended Run-Time
battery packs deliver 25% more run-time than the standard battery packs. XR2 PACK™
Extended Run-Time battery packs deliver 40% more run-time. NOTE: Your tool will accept
standard or extended run-time battery packs. However, be sure you have the proper voltage.
NOTE: The batteries in your battery pack are the nickel–cadmium type. Cadmium is consid-
ered to be a toxic material by the Environmental Protection Agency. Before disposing of dam-
aged or worn out Nickel–Cadmium battery packs, check with your state Environmental
Protection Agency to find out about special restrictions on the disposal of these battery packs
or return them to a DeWALT certified service center for recycling.
Battery Chargers
Your battery can be charged in D WALT 1 Hour Chargers or 15 Minute Chargers. Be sure to
E
read all safety instructions before using your charger.
Charging Procedure
These chargers require no adjustment and are designed to be as easy as possible to oper-
ate. Simply place your battery pack into the receptacle of a plugged in charger (FIG.1) and it
will automatically charge the pack.
HOT PACK DELAY
If your charger has a Hot Pack Delay feature: When the charger detects a battery that is hot, it
automatically starts a Hot Pack 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
Pack Delay mode.
Using Tune-Up™ Mode
The Tune-up™ mode will equalize or balance the individual cells in the battery pack at its peak
capacity. This cycle takes up to 8 hours to complete. Battery packs should be tuned up weekly
or after 10 to 20 charge/discharge cycles or whenever the pack no longer delivers the same
amount of work.
1. To tune up your battery pack, place the battery in the charger as usual. The red light will blink
continuously indicating that the charge cycle has started.
2. The Tune-up™ Button may be pressed at any time after the charge has started. The red light
will stop blinking momentarily, blink quickly 3 times, and then resume blinking continuously.
The charger is now giving your batteries a tune-up.
3. When the charge cycle has completed, the light will stay on continuously. The pack is fully
charged and may be used at this time or left in the charger.
4. If you select Tune-up™ and then change your mind, remove the battery from the charger.
After 5 seconds, insert the battery into the charger. The normal charge cycle will commence.
Installing and Removing the Battery Pack
LOCK-OFF TRIGGER SWITCH BEFORE INSTALLING BATTERY PACK (SEE FIG. 4).
NOTE: Make sure your battery pack is fully charged.
To install the battery pack into the tool handle, align the base of the tool with the notch inside
the tool's handle (Figure 2) and slide the battery pack firmly into the handle until you hear the
lock snap into place as shown in Figure 2.
To remove the battery pack from the tool, press the release buttons and firmly pull the bat-
tery pack out of the tool handle. Insert it into the charger as described in the charger section
of this manual.
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.
3. If the battery pack does not charge properly — (1) Check current at receptacle by plugging
in a lamp or other appliance, (2) Check to see if receptacle is connected to a light switch
which turns power off when you turn out the lights. (3) Move charger and battery pack to a
WALT battery pack. When ordering replacement
