SAFETY INSTRUCTIONS
WARNING Read all safety warnings, instructions,
illustrations and specifications. Failure to
follow all instructions listed below may result in electric shock,
fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE
REFERENCE.
The term “power tool” in the warnings refers to your mains-operated
(corded) power tool or battery-operated (cordless) power tool.
Work area safety
Keep work area clean and well lit. Cluttered or 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.
Electrical safety
Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
Battery tool use and care
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 re when used with another battery pack.
Use power tools only with specifically designated battery
packs. Use of any other battery packs may create a risk of injury
and re.
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 burns or a re.

4
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 burns.
Do not use a battery pack or tool that is damaged or modified.
Damaged or modied batteries may exhibit unpredictable behavior
resulting in re, explosion or risk of injury.
Do not expose a battery pack or tool to fire or excessive
temperature. Exposure to re or temperature above 265 °F (130 °C)
may cause explosion.
Follow all charging instructions and do not charge the battery
pack or tool outside the temperature range specified in the
instructions. Charging improperly or at temperatures outside the
specied range may damage the battery and increase the risk of re.
Service
Have your power tool serviced by a qualified repair person
using only identical replacement parts. This will ensure that the
safety of the power tool is maintained.
Never service damaged battery packs. Service of battery packs
should only be performed by the manufacturer or authorized service
providers.
Specific Safety Rules
Before using battery, read all instructions and cautionary mark-
ings on (1) battery charger, (2) battery pack, and (3) product
using battery.
Risk of re and burns. Do not recharge, disassemble, heat at
temperature above 265 °F (130 °C), or incinerate. Keep battery out
of reach of children and in original package until ready to use.
Battery tools do not have to be plugged into an electrical out-
let; therefore, they are always in operating condition. Be aware
of possible hazards when not using your battery tool or when
changing accessories.

5
Do not place battery tools or their batteries near fire or heat.
Charge battery pack within the required temperature range.
Store charger and battery pack in locations where temperature
is within the recommended storage temperature range. This is
important to prevent serious damage to the battery cells.
Do not crush, drop or damage the battery pack. Do not use a
battery pack or charger that has been dropped or received a
sharp blow. A damaged battery is subject to explosion. Properly
dispose of a dropped or damaged battery immediately.
Do not insert battery pack in charger if battery pack case is
cracked. Using damaged battery pack may result in electric shock
or re.
Batteries vent hydrogen gas and can explode in the presence
of a source of ignition such as a pilot light. To reduce the risk
of serious personal injury, never use any cordless product in the
presence of open ame. An exploded battery can propel debris and
chemicals. If exposed, ush with water immediately.
Do not recharge battery in damp or wet environment. Do not
expose charger to rain or snow. Water entering battery charger
may result in electric shock or re.
Do not store outside or in vehicles.
Do not store battery pack in charger. Battery pack stored in
charger over a long period of time could lead to battery pack
damage and re.
Battery leakage may occur under extreme usage or temperature
conditions. Avoid contact with skin and eyes. The battery liquid
is caustic and could cause chemical burns to tissues. If liquid comes
in contact with skin, wash quickly with soap and water. If the liquid
contacts your eyes, ush them with water for a minimum of 10
minutes and seek medical attention.
Do not let gasoline, oils, petroleum-based products, etc. come
in contact with plastic parts. They contain chemicals that can
damage, weaken or destroy plastic.

6
Do not touch the uninsulated portion of output connector or
uninsulated battery terminal. There is a risk of electric shock.
Replace battery pack if a substantial drop in operating time per
charge is observed. Battery pack may be nearing the end of its
life.
