WARNING
• Do not attempt to modify the battery pack or create accessories not recommended for use with this battery pack. Any such alteration or modification is misuse and could result in a hazardous condition leading to possible serious personal injury.

Before using the battery pack, read all instructions and cautionary markings on the battery pack, battery charger, and tools using the battery. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Before using it the first time, fully charge the battery pack.
A fully discharged battery pack will charge in about 70 minutes with charger KRC 2490-03 in a surrounding temperature between
41°F (5°C) and 104°F (40°C).

• 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.

Know your power tool. Read the operator’s manual carefully. Learn the tool’s applications and limitations, as well as the specific potential hazards related to this tool. Following this rule will reduce the risk of electric shock, fire, or serious injury.
• When the battery pack is not in use, keep it away from other metal objects like paperclips, 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 fire.
• Do not open the battery. There is a risk of a short circuit.
• Battery tools do not have to be plugged into an electrical outlet; they are always in operating condition. Be aware of possible hazards when not using your battery tool or when changing accessories. Following this rule will reduce the risk of electric shock, fire or serious personal injury.
• Do not place battery tools or their batteries near fire or heat. This will reduce the risk of explosion and possible injury.
• 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. Properly dispose of a dropped or damaged battery immediately.
• 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 flame. An exploded battery can propel debris and chemicals. If exposed, flush with water immediately.
• Do not charge the battery in a damp or wet location. Following this rule will reduce the risk of electric shock.
• For best results, your battery should be charged in a location where the temperature is greater than 41°F (5°C) and less than 104°F (40°C). Do not store outside or in vehicles.
