4.1 Mounting the Grinder

The DEWALT DW756 features an industrial cast iron base designed for stability. It is crucial to bolt the grinder securely to a sturdy workbench or a dedicated stand before use. While the manual may provide a template, it is often more accurate to use the actual base of the tool to mark and drill mounting holes. Ensure the mounting bolts are appropriate for your workbench thickness and provide a secure fit without overtightening, allowing the rubber feet to absorb vibration.

4.2 Installing Tool Rests

Attach the precision-machined aluminum tool rests to the grinder. These rests are essential for accurately positioning your work against the grinding wheels. Adjust them so that they are close to the grinding wheel but not touching, maintaining a small, consistent gap to prevent workpieces from getting caught.

4.3 Attaching Eye Shields and Spark Deflectors

Install the eye shields and spark deflectors. These components are critical for user safety, protecting against flying debris and sparks during operation. Ensure they are securely fastened and positioned to provide maximum protection. The plastic guards, while identical, may require careful orientation to ensure proper fit and function.
