This manual provides essential safety and operational instructions for the Sealey 1100W Angle Grinder. Always ensure the tool is unplugged before performing any assembly, accessory changes, or maintenance. Wear appropriate personal protective equipment (PPE) including eye protection, gloves, and a dust mask during operation.
Safety Instructions
Electrical Safety: Ensure the voltage rating matches your power supply. Regularly inspect cables and plugs for damage. Use an RCD (Residual Current Device) if operating in damp locations.
General Safety: Keep the work area clean and well-lit. Keep children and bystanders away. Do not operate in explosive atmospheres or near flammable materials.
Kickback Prevention: Maintain a firm grip and use the auxiliary handle. Avoid corners and sharp edges where the accessory might snag. Never attach saw chain woodcarving blades or toothed saw blades.
Assembly
Guard Assembly: The guard must be securely attached and positioned to provide maximum protection. Loosen the locking device to rotate the guard to the required angle, then re-tighten.
Attaching Discs: Ensure the grinder is unplugged. Place the clamping flange on the spindle with the raised ring facing upwards. Place the disc over the spindle. Use the spindle lock button to hold the spindle while tightening the retaining flange nut with the supplied pin wrench. Ensure the flange nut orientation matches the disc type (see figures in the manual).
Handle: Screw the side handle into the left, right, or top position on the grinder head for better control.
Operation
Preparation: Ensure the disc is correctly mounted and the guard is secure. Plug the tool into the power supply.
Switching On/Off: The switch is designed to prevent accidental starting. Slide the switch forward and press down to turn on. Press the rear of the switch to turn off; it will spring back to the OFF position.
Grinding: Do not switch the grinder on while the disc is in contact with the workpiece. Allow the disc to reach full speed before starting. Grind flat surfaces at an angle of 10° to 20°.
Maintenance
Cleaning: Keep the tool clean. Use a soft brush or dry cloth. Do not use caustic agents. If necessary, use clean, dry compressed air to blow through ventilation holes. Never let water contact the tool.
Inspection: Regularly check that all fixing screws are tight. If the tool requires repair, contact an authorized service centre.
