WARNING FOR CARBIDE BLANKS AND TOOLS:

Secure any long hair or loose clothing that might get tangled or caught in the machine's moving parts.

Long hair must be netted for safety around machine tools due to the extreme safety risk it poses.

Safety glasses should be worn.

Choose the necessary tools and prepare them. The length of the tool shouldn't stick out too far from the holder. Use only tools that have been properly sharpened. When changing tools, be careful not to interfere with the fixture or the work.

Securely clamp all work before running the machine. Machines may only be used with approved materials. Dust-producing materials that are abrasive will wear down machine parts.

Never blow chips from parts, machine surfaces, cabinets, controls, or the ground around the machine using compressed air. We are not responcible for any injury that may incur after purchase.
