IMPORTANT SAFETY

INSTRUCTIONS

  1. SAVE THESE INSTRUCTIONS—This manual contains important safety and operating instructions for Flex-Force 60V lithium-ion battery packs and Flex-Force 60V lithium-ion battery chargers.

  2. Before using the battery charger or battery pack, read all the instructions and cautionary markings on the battery charger, battery pack, and product using the battery pack.

  3. CAUTION—To reduce risk of injury, charge Flex-Force 60V lithium-ion battery packs with Flex-Force 60V lithium-ion battery chargers only. Other brands of battery packs may burst, causing personal injury and damage.

  4. WARNING—North America: Plugging the battery charger into an outlet that is not 120V can cause a fire or electric shock. Do not plug the battery charger into an outlet other than 120V. For a different style of connection, use an attachment plug adapter of the proper configuration for the power outlet if needed.

  5. WARNING—Other Regions: Plugging the battery charger into an outlet that is not 100 to 240V can cause a fire or electric shock. Do not plug the battery charger into an outlet other than 100 to 240V. For a different style of connection, use an attachment plug adapter of the proper configuration for the power outlet if needed.

  6. These devices comply with Part 15 of the FCC rules. Operation is subject to the following 2 conditions: (1) These devices may not cause harmful interference; and (2) these devices must accept any interference received, including interference that may cause undesired operation.

I. Training

  1. Do not allow children or untrained people to operate or service this device. Allow only people who are responsible, trained, familiar with the instructions, and physically capable to operate or service the device.

  2. Do not allow children to use or play with the battery pack or battery charger; local regulations may restrict the age of the operator.

II. Preparation

  1. Use appliances only with specifically designated battery packs. Using other types of battery packs may create a risk of injury and/or fire.

  2. Do not use a damaged or modified battery pack or battery charger. It may exhibit unpredictable behavior, resulting in fire, explosion, or risk of injury.

  3. If the supply cord to the battery charger is damaged, contact an Authorized Service Dealer or distributor to replace it.

III. Operation

  1. Charge the battery pack with only the battery charger specified by the tool manufacturer. A charger suitable for 1 type of battery pack may create a risk of fire when used with another battery pack.

  2. Charge the battery pack in a well-ventilated area only.

  3. Follow all charging instructions and do not charge the battery pack outside of the temperature range specified in the instructions. Otherwise, you may damage the battery pack and increase the risk of fire.

  4. Under abusive conditions, the battery pack may eject liquid; avoid contact. If you accidently come into contact with the liquid, flush with water. If the liquid contacts your eyes, seek medical help. Liquid ejected from the battery pack may cause irritation or burns.

  5. Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130°C (265°F) may cause explosion.

  6. CAUTION—A mistreated battery pack may present a risk of fire, explosion, or chemical burn.

    • Do not disassemble the battery pack.

    • Replace the battery pack with a genuine Flex-Force battery pack only; using another type of battery pack may cause a fire or risk of injury.

    • Keep battery packs out of the reach of children and in the original packaging until you are ready to use them.

IV. Maintenance and Storage

  1. Do not allow children to clean or maintain the battery charger.

  2. When the battery pack is not in use, keep it away from metal objects such as paper clips, coins, keys, nails, and screws that can make a connection from 1 terminal to another. Shorting the battery terminals may cause burns or a fire.

  3. Do not attempt to repair the battery pack or battery charger. Have an Authorized Service Dealer or distributor perform service on the battery pack or battery charger using identical replacement parts to ensure that the product is safely maintained.

  4. Check with local codes for possible special battery disposal instructions.
