Setup

Attaching the Auxiliary Handle:

The auxiliary handle can be attached to either side of the grinder head for left-handed or right-handed operation, providing optimal control and comfort. Screw the handle firmly into the designated threaded hole until secure.

Installing the Protective Guard:

The protective guard is essential for safety. Loosen the guard's clamping screw, position the guard over the spindle housing, and rotate it to cover the disc as much as possible, directing sparks away from you. Tighten the clamping screw securely.

Mounting the Grinding/Cutting Disc:

1. Ensure the tool is unplugged from the power source.
2. Press and hold the spindle lock button.
3. Place the inner flange onto the spindle.
4. Position the desired 4-1/2" abrasive disc onto the inner flange, ensuring it sits flat.
5. Screw the outer flange onto the spindle.
6. Use the two-pin wrench to firmly tighten the outer flange, securing the disc. Release the spindle lock.

Operating Instructions

General Operation:

Before starting, ensure the power cord is in good condition and connected to a 120V power outlet. Hold the grinder firmly with both hands, using the main handle and the auxiliary handle. The tool features a switch with a continuous use function for prolonged tasks.

Grinding Applications:

For grinding, position the disc at a slight angle (typically 15-30 degrees) to the workpiece. Apply moderate pressure and move the grinder smoothly across the surface. Avoid excessive pressure, which can overload the motor and damage the disc.

Cutting Applications:

When cutting, use a thin cutting disc and hold the grinder perpendicular to the workpiece. Make shallow passes, gradually deepening the cut. Do not twist or bind the disc in the cut, as this can cause kickback or disc breakage.

Maintenance

Cleaning:

Regularly clean the ventilation openings of the tool to prevent overheating. Use a soft brush or compressed air to remove dust and debris. Do not use water or chemical cleaners.

Disc Replacement:

Replace worn or damaged discs immediately. Follow the disc mounting instructions in the "Setup" section. Always use discs with the correct diameter and arbor size (4-1/2" and 5/8-11 UNC-1A spindle).

Carbon Brushes:

The carbon brushes are wear parts. If the motor performance decreases or sparks become excessive, the carbon brushes may need replacement. This should ideally be performed by a qualified service technician.

Storage:

Store the angle grinder in a dry, secure place, out of reach of children. Protect it from direct sunlight and extreme temperatures.
