@

rhc]

_as
-JI-

a) Recharge only with the charger specified by the manufacturer.
A charger that is
suitable for one type of battery pack may create a risk of fire when used with another battery
pack.
b) Use power tools only with specifically designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
c) 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 bums or a fire.
d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If
contact accidentally
occurs, flush with water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the battery may cause irritation or bums.

AND INSTRUCTIONS
REFERENCE

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or batteryoperated (cordless) power tool.
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders
cause you to lose control

away while operating a power tool. Distractions can

2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not
use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators,
ranges and refrigerators.
There is an increased risk of electric shock if your body is earthed
or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
power tool Keep cord away from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattention while operating power tools may
result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off position before
connecting
to power source and/or battery pack, picking up or carrying the tool
Carrying power tools with your finger on the switch or energizing power tools that have the
switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a
key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in
moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of dust collection can reduce dustrelated hazards.
4) POWER TOOL USE AND CARE
a) Do not force the power tool Use the correct power tool for your application.
The
correct power tool wll/ do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source andlor the battery pack from the power
tool before making any adjustments,
changing accessories, or storing power tools.
Such preventive safety measures reduce the risk of starting the power tool accidentally.
d) Store idle powertools
out of the reach of children and do not allow persons unfamiliar
with the power tool or these instructions
to operate the power tooL Power tools are
dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment
or binding of moving parts, breakage
of parts and any other condition that may affect the power tool's operation. If
damaged, have the power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control
g) Use the power tool, accessories
and tool bits, etc. in accordance
with these
instructions,
taking into account the working conditions
and the work to be
performed. Use of the power tool for operations different from those intended could result in
a hazardous situation.

Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
Hold power tool by insulated gripping surfaces, when performing an operation where
the cutting accessory may contact hidden wiring. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power tool "live" and could give the operator an
electric shock.
• 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.
• Wear safety goggles or other eye protection. Hammering and drilling operations cause
chips to fly. Flying particles can cause permanent eye damage.
• Keep a firm grip on the tool at all times. Do not attempt to operate this tool without holding
it with both hands.
• Accessories and tool may get hot during operation. Wear gloves when handling them if
performing heat producing applications such as hammerdril/ing and drilling metals.
• Do not operate this tool for long periods of time. Vibration caused by hammer action may
be harmful to your hands and arms. Use gloves to provide extra cushion and limit exposure by
taking frequent rest periods.
• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long
hair can be caught in moving parts.
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use
face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENX
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI $12.6 ($3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.

batteries. Any other uses may result in risk of fire, electric shock or electrocution.
Do not expose the charger to rain or snow.
Pull by the plug rather than the cord when disconnecting the charger. This will reduce the
risk of damage to the electric plug and cord.
Make sure that the cord is located so that it will not be stepped on, tripped over or
otherwise subjected to damage or stress.
Do not use an extension cord unless it is absolutely necessary. Use of improper extension
cord could result in risk of fire, electric shock or electrocution.
When operating a charger outdoors, always provide a dry location and use an extension
cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
An extension cord must have adequate wire size (AWG or American Wire Gauge) for
safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is,
16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. When using more than one extension to make up the
total length, be sure each individual extension contains at least the minimum wire size. The following
table shows the correct size to use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The lower the gauge number, the heavier the cord.

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.
if, WARNING: Shock hazard. Don't allow any liquid to get inside the charger. Electric shock may
result.
,t_,WARNING: Bum 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.
