3. Dual-handle design ensures enhanced control and stability during use.
4. Comes with a robust wheel guard for added protection.

Safety & Usage Guidelines for the Grinder:

1. Before initiating operations, ensure the switch is in the 'off' position. Firmly grip the machine to prevent any unexpected movements upon startup.

2. The motor and gear operations generate heat. The built-in fan in the angle grinder aids in cooling. A moderate temperature, felt on the plastic components, is typical and safe.

3. Post-operation, the fan ceases its cooling function. The machine then relies on its aluminum head shell for heat dissipation. It's normal for the head shell to feel warm. Newer machines might exhibit more warmth due to gear adjustments, but this will stabilize with continued use.
