CAUTION
The battery used in this device may present a risk of re or chemical burn if mistreated.
CAUTION
Risk of Fire and Burns. Do Not Open, Crush, Heat Above 100°C(212°F) or Incinerate. Follow
Manufacturer’s Instructions.
CAUTION
When the 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.
CAUTION
Under abusive conditions, a liquid may be ejected from the battery; avoid contact. If contact
accidentally occurs, ush with water. If the liquid makes contact with your eyes, seek medical help.
Liquid ejected from the battery may cause irritation or burns.
CAUTION
Do not use a battery pack that is damaged or modied. Damaged or modied batteries may exhibit
unpredictable behavior resulting in re, explosion or risk of injury.
• When charging, make sure the temperature is between 6°C and 40°C (43 - 104°F), -14°C and
45°C (6.8 - 113°F) For discharge.
• Do not use a damp cloth or detergent on the battery or battery charger.
• Always remove the battery pack before cleaning, inspecting, or performing any maintenance on
the tool.
• Have services performed by a qualified repair person using only identical replacement parts.
This will ensure that the safety of the product is maintained.
• If the battery pack case is cracked or damaged, do not insert into the charger. Replace the
battery pack.
• Battery powered tools do not have to be plugged into an electrical outlet; therefore, they are
always in operating condition. Be aware of possible hazards when not using your battery
powered tool or when changing accessories. Following this rule will reduce the risk of electric
shock, re, or serious personal injury.
• Do not place the battery in high-temperature locations, such as near a re, heater, etc.
• 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 an explosion.

IMPORTANT SAFETY INSTRUCTIONS

• Batteries 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 charge the battery in a damp or wet location. Following this rule will reduce the risk of
electric shock.
• Under extreme usage or temperature conditions, battery leakage may occur. If liquid comes in
contact with your skin, wash immediately with soap and water. If liquid gets into your eyes, ush
them with clean water for at least 15 minutes, then seek immediate medical attention. Following
this rule will reduce the risk of serious personal injury.
• Keep battery pack dry, clean, and free from oil and grease. Always use a clean cloth when
cleaning. Never use brake uids, gasoline, petroleum-based products, or any solvents to clean
battery pack.

OPERATION
CHARGING THE BATTERY PACK
Battery packs are shipped in a low charge condition to prevent possible problems. Therefore,
you should charge before rst use. If the charger does not charge the battery pack under normal
circumstances, return both the battery pack and charger to your nearest Authorized Service Center
for service.
• Charge the battery pack only with the recommended charger.
• Connect the charger to a power supply. For approved power sources, refer to the operator’s
manual of the charger.
• Make sure the battery pack is secured in the charger before beginning operation.

the contacts in the charger.
• The battery pack may become slightly warm to the touch while charging. This is normal and does
not indicate a problem.
• Do not place the charger and battery pack in an area of extreme heat or cold. They will work best
at normal room temperature.
• When batteries become fully charged, unplug the charger from the power supply and remove the
battery pack.
