1.2 Protective Guard Installation

The protective guard is crucial for safety. Position the guard over the spindle head, ensuring it covers the top and sides of the disc. Secure it firmly according to the tool's mechanism, typically by tightening a screw or engaging a quick-release lever. Ensure it is correctly oriented to deflect sparks away from you.

1.3 Disc Installation

To install a disc, first ensure the grinder is switched off and the battery is removed. Press the spindle lock button to prevent the spindle from rotating. Place the inner flange onto the spindle, then position the desired cutting, grinding, or flap disc onto the inner flange. Finally, screw on the outer flange and tighten it securely with the provided wrench. Ensure the disc is centered and firmly held.

2. Operating Instructions

2.1 Power On/Off

To power on the grinder, ensure the battery is inserted and the protective guard and disc are correctly installed. Press the safety lock button (if present) and then squeeze the trigger switch. To turn off, release the trigger switch. Always maintain a firm grip on the tool.

2.2 Speed Adjustment

The Gisam Angle Grinder features 4-stage speed regulation. Use the speed selector switch to choose the appropriate RPM for your material and task. Lower speeds are suitable for fine machining or polishing, while higher speeds are for rapid cutting and heavy-duty grinding.

• Speed 1 (3500 RPM): Fine machining.
• Speed 2 (6500 RPM): Light grinding, cutting, repair work.
• Speed 3 (9500 RPM): High-efficiency cutting, moderate grinding.
• Speed 4 (12000 RPM): Rapid cutting, heavy-duty grinding.

2.3 Cutting and Grinding Techniques

Always wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and hearing protection. Position the workpiece securely. For cutting, use a cutting disc and apply steady, even pressure, allowing the disc to do the work. For grinding, use a grinding disc and maintain an angle of approximately 15-30 degrees to the workpiece for optimal material removal and control.
