Step-by-Step Guide to Changing the Drill Chuck
Changing the drill chuck on your DeWalt DCD 796 is a straightforward process if you follow these steps carefully.
Step 1: Prepare Your Workspace
Before starting, ensure your workspace is organized and free of clutter. Turn off and unplug your drill for safety. If it’s a battery-operated model, remove the battery to avoid any mishaps.
Step 2: Remove the Old Chuck
