2. General Safety Instructions

Always follow basic safety precautions when using electrical tools to reduce the risk of fire, electric shock, and personal injury. Read all instructions carefully before operating this sander.

2.1 Work Area Safety

• Keep the 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. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2.2 Electrical Safety

• Power tool plugs must match the outlet. Never modify the plug in any way.
• Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep cord away from heat, oil, sharp edges, or moving parts.

2.3 Personal Safety

• Always wear eye protection. Use safety glasses or goggles.
• Wear appropriate dust mask or respirator, especially when sanding wood or materials that produce fine dust.
• Wear hearing protection when operating the sander for extended periods.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts.
• Stay alert, watch what you are doing, and use common sense when operating a power tool.

2.4 Sander Specific Safety

• Always secure the workpiece firmly before sanding.
• Ensure the sanding belt and disc are correctly installed and tensioned before use.
• Never sand materials containing asbestos.
• Do not apply excessive pressure to the workpiece; let the sander do the work.
• Always disconnect the power supply before changing sanding belts/discs or performing any maintenance.
