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 flam-
mable 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
• 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 suitable
for one type of battery may create a risk of fire when used with another battery.
• Use battery operated tool only with the specifically designated 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. Air vents often cover moving parts and should also be avoided.
• Avoid accidental starting. Be sure switch is in the locked or off position before inserting bat-
tery 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 a 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 a 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 pre-
ventative safety measures reduce the risk of starting the tool accidentally.
• Store idle tools out of reach of children and other untrained persons. Tools are dan-
gerous in the hands of untrained users.
• 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 con-
nection 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 edges 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 tools 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 mainte-
nance performed by unqualified personnel 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 cut-
ting tool may contact hidden wiring or its own cord. Contact with a "live" wire will make
exposed metal parts of the tool "live" and shock the operator.
CAUTION: Wear appropriate personal hearing protection during use. Under some con-
ditions and duration of use, noise from this product may contribute to hearing loss.
CAUTION: Some tools with large battery packs will stand upright on the battery pack but may
be easily knocked over. When not in use, place tool on its side on a stable surface where it will
not cause a tripping or falling hazard.
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.
• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling,
and other construction activities. Wear protective clothing and wash exposed areas
with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may pro-
mote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust, which may cause serious and
permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face and body.

Introduction
Some chargers are designed to use standard 120 volt AC, 60 Hz power. A vehicular charger will
charge from 12 volts through a cigarette lighter socket. Charge time is approximately one hour.
Extended Run-Time battery packs may require slightly longer charge.

Charging Procedure (Fig. 1)
These chargers require no adjustment and are designed to be as easy as possible to operate.
Simply place your battery pack into the receptacle of a plugged in charger (Fig. 1) and it will auto-
matically charge the pack.

PROBLEM POWER LINE
If your charger has a Problem Power Line indicator: 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, flashing the red light with two fast blinks followed by a
pause. This indicates the power source is out of limits.
HOT/COLD PACK DELAY
If the charger detects a battery that is hot or excessively cold, it automatically starts a Hot/Cold
Pack Delay, suspending charging until the battery temperature has stabilized. 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 Pack Delay mode.
Installing and Removing the Battery Pack (Fig. 2 & 3)
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 (Fig. 2) and slide the battery pack firmly into the handle until you hear the lock snap
into place. To remove the battery pack from the tool, press the release buttons and firmly pull
the battery pack out of the tool handle as shown in Fig. 3. Insert it into the charger as described
in the charger section of this manual.
NOTE: Battery storage and carrying caps are provided for use whenever the battery
is out of the tool or charger. Remove cap before placing battery in charger or tool.
WARNING: 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.
without battery cap. 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.
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 — (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 location
where the surrounding air temperature is approximately 65°F - 75°F (18°- 24°C). (4) If
charging problems persist, take or send 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 in to 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, 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 immerse charger in water or any other liquid.
