2. Important Safety Instructions
Always observe the following safety precautions to reduce the risk of electric shock, fire, and serious injury.

- Power Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Do not use the power tool if the switch does not turn it on and off. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.
- Battery Tool Use and Care: Recharge only with the charger specified by the manufacturer. Use power tools only with specifically designated battery packs.
