Here are the precautions for using an angle grinder: 1. Pre-use inspection: Before operation, the operator should check whether the accessories are intact, whether the insulation cable is damaged or aged, etc. After inspection, plug in the power supply before starting work. 2. Replacing the grinding wheel: When the grinding wheel is worn out and needs to be replaced, the power must be disconnected to prevent unnecessary accidents. 3. Preventing overheating: After continuous use for more than 30 minutes, the grinder should be stopped and allowed to rest for at least 20 minutes until it cools down before resuming operation. Prolonged use can cause overheating, which may lead to damage and work-related accidents.
Never be careless when using an angle grinder—I've personally witnessed injuries caused by improper operation. Before starting, always wear full protective gear: safety goggles to block flying debris, cut-resistant gloves to protect your hands, and earplugs if possible to prevent noise damage. Avoid loose clothing while working, as it can get caught in the machine. Stand firmly, grip the tool with both hands, and maintain a cutting angle of around 90 degrees—never apply sideways pressure. The most dangerous risk is a cutting disc shattering, so always inspect the grinding wheel for cracks before use and replace any old or abnormally noisy discs immediately. Keep the spark zone away from flammable materials like paint cans or wood shavings. Always unplug the tool when changing discs and tighten the nut securely. After each use, clean off dust and perform maintenance to extend the tool's lifespan.
