How to use

Attach the appropriate 125 mm abrasive disc, connect dust extraction if available, and switch on the sander.

Change abrasive grit progressively from coarse to fine for successive stages of preparation and finishing. Always follow the manufacturer's safety instructions and ensure the workpiece is securely fixed.

Recommendations

Do not use the sander near flammable materials. Wear appropriate eye, hearing and dust protection when sanding, and use recommended abrasive grits for the material and stage of work.
