Cup Brush OverView
Recommended Use: Cleaning
- Primary application: For fast cleaning of large surfaces
- Knot Wire: For low to medium flexibility and aggressive cutting action
- Crimped Wire: Higher flexibility for light cleaning and removal, especially on irregular surfaces
How to correctly use and angle grinder
Hold the grinder firmly and use your free hand on the side handle to steadily let it come up to full speed before you touch the cup brush to the work surface. This helps keep your actions smooth and consistent. You will want the speed of the cup brush to do the work, so don't press too hard on the work surface. It's important to angle the grinder correctly to reduce the risk of injury.
It is important that you read the instruction manual for your angle grinder and the specifications for the wire cup brush you are using.
Wire Cup Brush Safety Requirements
- Safety Goggles: Safety goggles, or full face shields worn over safety glasses with side shields, MUST BE WORN by all OPERATORS and OTHERS IN THE AREA OF POWER BRUSH OPERATIONS. Comply with the requirements of ANSI Z87.1 (“Occupational Eye and Face Protection”).
- Guards: Keep all machine guards in place.
- Speeds: Observe all speed restrictions indicated on the brushes, containers, labels, or printed in pertinent literature. “MSFS” or “MAX.SFS” means Maximum Safe Free Speed (R.P.M.) - spinning free with no work applied. For reasons of safety, the “MSFS/MAX.SFS” should not be exceeded under any circumstances.
- Safety Standard: Comply with the safety standards of the American National Standards Institute, ANSI B165.1 and ANSI B165.2 - “Safety Requirements - Power Brushes.”
- Protective Equipment: Appropriate protective clothing and equipment (such as full face shield, gloves, respirator, etc.) must be used where a possibility of injury exists that can be prevented by such equipment.
- Before starting brush: Use eye protection and safety equipment. Inspect brush for rust, damage, speed limit, etc. If no-load speed marked on the power tool is higher than the brush speed limit, do not mount brush. Inspect and jog machine to assure the brush is mounted properly and securely, machine guards are in place, no vibration, etc. Run machine at operating speed for at least one minute before applying work. DO NOT STAND IN FRONT OF OR IN LINE WITH BRUSH.
