• Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Avoid body contact with earthed or grounded surfaces. Do not expose power tools to rain or wet conditions.
• Personal Safety: Always wear eye protection (safety glasses or goggles) and hearing protection. Use a dust mask if operations create dust. Dress properly; avoid loose clothing or jewelry.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.
• Double Safety Switch: The HYCHIKA Mini Circular Saw is equipped with a double protection switch to prevent accidental startup. Both the lock-off button and the trigger must be pressed simultaneously to operate the saw.
• Spindle Lock: Use the spindle lock button only when the saw blade is completely stopped to change blades.
