3. Safety Instructions

WARNING: Always wear appropriate personal protective equipment (PPE) including safety glasses, hearing protection, and gloves when operating the angle grinder. Read and understand all safety warnings and instructions before use.

General Power Tool Safety:

• Work Area Safety: Keep your work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
• Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Avoid body contact with earthed or grounded surfaces. Do not expose power tools to rain or wet conditions.
• Personal Safety: Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication. Dress properly; avoid loose clothing or jewelry.
• Power Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.

Angle Grinder Specific Safety:

• Always ensure the guard is properly installed and adjusted for maximum safety.
• Use only wheels that are rated for the grinder's maximum RPM.
• Secure the workpiece. Use clamps or a vise to hold the workpiece firmly.
• Be aware of kickback. Always maintain a firm grip on the tool and position your body and arm to resist kickback forces.
• Allow the wheel to reach full speed before contacting the workpiece.
• Never use the side of a cutting wheel for grinding.
• After turning off the tool, wait until the wheel has completely stopped before setting the tool down.

4. Setup

Attaching the Auxiliary Handle:

The auxiliary handle can be installed in two positions (left or right) to provide optimal control and comfort for both right-handed and left-handed users. Simply screw the handle into the desired threaded opening on the grinder's gear housing until it is secure.

Installing Abrasive Wheels:

Always ensure the grinder is unplugged from the power source before changing wheels.

1. Step 1: Press and hold the spindle lock button located on the top of the gear housing.
2. Step 2: Use the provided spanner wrench to loosen and remove the flange nut.
3. Step 3: Place the desired abrasive wheel onto the spindle. Ensure the wheel is correctly oriented (refer to Figure 4.3 for specific wheel types).
4. Step 4: Replace the flange nut and tighten it securely with the spanner wrench while still holding the spindle lock button. Release the spindle lock once the nut is tight.

Always ensure the tool is held firmly with both hands during operation. Apply steady, even pressure and allow the tool to do the work. Avoid excessive pressure, which can damage the wheel or motor.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your angle grinder.

• Cleaning: After each use, clean the tool with a soft cloth to remove dust and debris. Use compressed air to clear the ventilation openings (wind tunnel and heat emission holes) to prevent overheating.
• Carbon Brush Replacement: The motor uses carbon brushes which wear down over time. If the tool experiences reduced power or intermittent operation, the carbon brushes may need replacement. Refer to a qualified service technician for this procedure. (Note: The package includes 2 spare carbon brushes).
• Cord Inspection: Regularly inspect the power cord for any signs of damage, cuts, or fraying. Do not use the tool if the cord is damaged.
• Storage: Store the angle grinder in a dry, secure location out of reach of children and away from direct sunlight or extreme temperatures.
