2. Safety Instructions

Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury when using power tools.

• Work Area Safety: Keep your work area clean and well-lit. Cluttered or dark areas invite accidents.
• Electrical Safety: Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Personal Safety: Always wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, and gloves. Secure loose clothing and long hair.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.
• Secure Workpiece: Always clamp or otherwise secure the workpiece to a stable platform. Holding the workpiece by hand or against your body is unstable and may lead to loss of control.
• Safety Lock Button: The saw is equipped with a safety lock button to prevent accidental starting. Always engage the safety lock when the tool is not in use or when changing blades.
