Product Overview
The Sealey 1100W Angle Grinder (SG125EU.V2) is a heavy-duty power tool designed for grinding applications. It features a 125mm disc capacity, a powerful 1100W motor reaching 12000rpm, and a vibration-reducing composite body for improved comfort.

Safety Precautions
Warning: Failure to follow safety instructions can result in electric shock, fire, or serious injury. Always wear appropriate personal protective equipment (PPE), including eye protection, gloves, and a dust mask. Ensure the work area is clean, well-lit, and free of flammable materials. Never operate the tool in explosive atmospheres. Always disconnect the power supply before performing any maintenance or changing accessories.
Assembly
Before assembly, ensure the tool is unplugged. The safety guard must be securely attached and positioned to protect the operator from sparks and debris. To attach a disc, use the spindle lock button to hold the spindle stationary while tightening the retaining flange nut with the provided pin wrench. Ensure the flange orientation matches the specific disc type (flat or depressed center) as shown in the manual's diagrams.
Operation
The grinder features an ON/OFF switch designed to prevent accidental starting. To operate, slide the switch forward and press down. If power is interrupted, release the trigger immediately. When starting, the tool may kick to the right; maintain a firm grip with both hands using the side handle. Grind at an angle of 10° to 20° to the workpiece for optimal results. Do not apply excessive pressure or jam the disc.
Maintenance
Regularly inspect the tool for loose screws and ensure air vents are clean to prevent motor overheating. Use a soft brush or dry cloth for cleaning; never use caustic agents or water. Store the tool in a secure, dry, and childproof location. For repairs, contact Sealey at [email protected] or 01284 757505.
