User Tips

Safety First

Always wear appropriate personal protective equipment — including eye protection, hearing protection, and work gloves — when using an angle grinder to guard against sparks and debris.

Choose the Correct Disc

Select a grinding or cutting wheel that’s rated for 100 mm diameter and compatible with the task at hand (e.g., metal cutting, masonry grinding).

Allow Tool Break-In

Initial use may produce heavier friction or sparks; operate briefly at moderate pressure to help seat components before heavier work.

Keep Clean & Cool

Regularly clear debris from airflow vents and avoid prolonged operation without breaks to help prevent overheating.
