• Note - Wire bore brush is for push-pull operations only. Mounted on a drill or corresponding driver handle, do not spin more than 2000 rpm.

• Select the Right Brush — Choose a brush from the 5-piece set whose 9mm diameter and 75mm head length fit your specific tube, port, or bearing opening. Ensure it can pass freely into the area needing cleaning.
• Mount for Power or Manual Use — For powered cleaning, securely attach the 1/4 inch hex shank to a drill or die grinder. For manual cleaning, use the corresponding driver handle. Do not exceed 2000 RPM if using power tools.
• Perform Push-Pull Cleaning — Use the brush in a push-pull motion within the tube or confined area. Apply moderate pressure to remove rust, dirt, or other residues. Avoid spinning the brush excessively, especially in delicate components.
• Clean and Store — After use, clean the brush bristles to remove debris. Store in a dry place to prevent rust and maintain bristle integrity for future use. Ensure the hex shank is clean before re-mounting.
