Device description
The angle grinder features a spindle lock, an ON/OFF switch, an additional handle, a protective guard, and a flange nut wrench. It is powered by a lithium-ion battery with a capacity indicator.
Assembly and installation
Additional handle: The handle can be attached in three positions (A, B, C) to suit right-handed or left-handed users and for specific cutting tasks. The grinder must not be used without the additional handle.
Protective guard: The guard can be adjusted to protect your hands by directing sparks and debris away from your body. Ensure the guard is securely fastened before operation.

Safety and maintenance
