Maintaining your electric angle grinder is essential for safety and longevity. Tim Carter of Ask the Builder notes that regular inspections can prevent accidents.

A well-maintained grinder is less likely to malfunction and cause injury.

Influencer and woodworking expert, Ana White, emphasizes that unplugging your tool is a crucial step in preventing accidental startups, which can lead to serious injuries.
